The Cost of Deregulation and Ignored Warnings

The Grenfell Tower Inquiry published its Phase 2 report on September 4 2024. The document spans seven volumes and details the exact failures that led to the deaths of 72 people on June 14 2017. Sir Martin Moore Bick and his team concluded that the disaster resulted from decades of failure by central government. The investigation proved that consecutive administrations prioritized deregulation over life safety. Officials ignored clear warnings about combustible cladding materials for 25 years.

The report exposed a culture where government departments treated fire safety regulations as an obstacle to business. The drive to reduce red tape meant that civil servants dismissed urgent recommendations from coroners and parliamentary committees. The Inquiry found that the government department responsible for building regulations displayed a complacent and defensive attitude. This environment allowed product manufacturers to engage in deliberate dishonesty. Companies manipulated testing processes to conceal the extreme dangers of their flammable products.

A Timeline of Dismissed Evidence

The government received multiple warnings about external fire spread on residential buildings long before the Grenfell Tower fire. In 1991 a fire at Knowsley Heights in Merseyside demonstrated how flames could travel rapidly up combustible external panels. Officials recorded the event took no meaningful action to restrict the use of these materials.

In 1999 a similar fire occurred at Garnock Court. The Environment and Transport Select Committee investigated the incident and recommended that the government replace the existing Class 0 rating with a full size physical test for external cladding systems. The government failed to implement this recommendation. The Class 0 rating remained in place and allowed dangerous materials to be certified as safe for use on tall buildings.

The Building Research Establishment conducted a full size physical test in 2001 using Aluminum Composite Material panels with unmodified polyethylene cores. The panels burned violently and failed the test completely. The government received these results chose not to publish them. Officials did not warn the construction industry about the extreme risks associated with Aluminum Composite Material panels. The Inquiry concluded that this specific failure kept the industry blind to a lethal threat.

In 2009 a fire at Lakanal House killed six people. The coroner investigating the deaths issued a formal recommendation in 2013 for the government to urgently review Approved Document B. This document contained the statutory guidance on fire safety. The government response to the coroner was deficient. Officials delayed the review and left the flawed guidance untouched until after the Grenfell Tower disaster.

Corporate Deception and Regulatory Collapse

The Phase 2 report detailed how the absence of strict government oversight enabled corporate malpractice. Manufacturers like Arconic, Kingspan, and Celotex exploited the weak regulatory environment. The Inquiry found that these companies used deliberate strategies to market highly combustible products for use on tall buildings. They manipulated test results and provided misleading information to certification bodies.

The Building Research Establishment, which operated as a privatized entity, demonstrated poor record keeping and compromised scientific rigor. The organization allowed manufacturers to dictate testing conditions. The Inquiry noted that the Building Research Establishment was reluctant to alert the government to the dangers of the cladding products it tested. Reports drafted by the organization used vague language that obscured the true risks to human life.

The Kensington and Chelsea Tenant Management Organisation also failed in its basic duties. The organization managed Grenfell Tower and ignored the safety concerns raised by residents. The Phase 2 report identified serious failures in fire risk assessments and evacuation strategies. The management body allowed the relationship with residents to worsen and demonstrated a continuous indifference to fire safety between 2009 and 2017.

Architectural Incompetence and Contractor Failures

The Inquiry found that the choice of combustible materials for the Grenfell Tower refurbishment resulted from severe incompetence among the organizations involved. Studio E acted as the architects for the project. Rydon served as the main contractor. Harley operated as the subcontractor. The Phase 2 report stated that all three entities failed to identify their own responsibilities for important aspects of the design. Each company assumed that someone else was responsible for matters affecting fire safety. This created an environment of buck passing that allowed dangerous design choices to proceed unchallenged.

The report also criticized the fire engineer assigned to the project. The Inquiry determined that the fire engineer was insufficiently qualified and did not possess the requisite technical expertise to determine whether the building achieved fire safety. The engineer failed to produce a final fire strategy for the refurbished tower. In response to these findings the Inquiry recommended that the fire engineering profession be formally recognized and regulated by an independent statutory body.

Emergency Response and Control Room Deficiencies

The Phase 2 report examined the response of the London Fire Brigade on the night of the fire. The Inquiry found that senior officers were complacent and did not possess the skills to recognize the problems and correct them. The firefighters who attended the scene were not prepared for a fire spreading rapidly up the exterior of a tall building. The London Fire Brigade knew about the challenges of fighting fires in tall buildings after the Lakanal House fire in 2009 failed to share knowledge or plan for a large volume of emergency calls.

Between 2013 and 2017 existing control room staff did not receive the full day of fire survival guidance refresher training that the brigade promised to the coroner. The control room suffered from serious staffing problems and underwent disruptive restructuring during those years. The report noted that firefighters were forced to respond to a building that was wrapped in petrol without the proper training to deal with a catastrophic event.

Government Response and Future Legislation

The Westminster government published its formal response to the Phase 2 report on February 26 2025. The administration accepted 49 of the 58 recommendations in full. The remaining 9 recommendations were accepted in principle. The government committed to creating a single Construction Regulator to oversee the entire industry. This new body replaces the fragmented system that allowed the Grenfell Tower disaster to occur.

The Inquiry also recommended that the government be legally required to maintain a publicly accessible record of recommendations made by select committees, coroners, and public inquiries. This record must include a description of the steps taken in response to each recommendation. If the government decides not to accept a recommendation, it must record its reasons and report annually to Parliament.

The Fire Brigades Union reviewed the Phase 2 report and stated that the findings completely vindicated their long standing warnings about deregulation. The union noted that firefighters were put in an impossible position on the night of the fire because the building was wrapped in petrol. The union demanded that the systems for delivering building safety be brought under public ownership.

Data on Ignored Fire Safety Warnings

The publication of the Phase 2 report marks the end of the public inquiry initiates a new phase of legislative reform. The government published a Construction Products Reform Green Paper alongside its formal response in February 2025. This document outlines proposals to overhaul the testing and certification of building materials. By February 2026 the government released the Construction Products Reform White Paper to finalize these regulatory changes. The data confirms that 72 people died because officials prioritized commercial interests over human life. The implementation of the 58 recommendations determines if the government can permanently correct the failures that defined the preceding decades.

The Deliberate Concealment of Fire Test Failures

The Grenfell Tower Inquiry Phase 2 report published on September 4 2024 exposes a calculated strategy by Arconic Architectural Products to hide the true fire performance of its Reynobond PE 55 cladding. Arconic manufactured the aluminum composite material panels used on the exterior of Grenfell Tower. These panels contained a highly combustible polyethylene core. The Inquiry found that Arconic deliberately and dishonestly concealed the danger of using these panels in a cassette format.

Arconic conducted fire tests on the Reynobond PE 55 panels in 2004 and 2005. The panels could be attached to a building using two different methods. Installers could bolt the panels flat against the wall using rivets. Installers could also bend the panels into a cassette shape and hang them on hidden rails. The 2004 and 2005 tests revealed a massive difference in fire performance between the two methods. The riveted panels achieved a Euroclass B rating. The cassette panels performed disastrously. The cassette variant burned violently and the testing facility had to stop the test after 850 seconds. The cassette variant released seven times more heat and three times as much smoke as the riveted version. The cassette format received a Euroclass E rating. This rating prohibited its use on high rise buildings.

Even with this knowledge Arconic did not withdraw the cassette variant from the market. The company branded the 2005 test a rogue result did not conduct further tests to verify that assumption. Arconic continued to market the Reynobond PE 55 panels as a Euroclass B product.

The Misleading Certification Process

Arconic required a safety certificate to sell its products in the United Kingdom. The company applied for certification from the British Board of Agrément in 2008. The contract required Arconic to provide all available test data to the certification body. Arconic supplied the successful test results for the riveted panels. Arconic withheld the disastrous test results for the cassette panels.

The British Board of Agrément granted a certificate stating that the Reynobond PE 55 panels achieved a Class 0 rating. This certificate included diagrams for both the riveted and cassette installation methods. The certification body based its approval entirely on the riveted test data. Arconic president Claude Schmidt testified at the Inquiry in February 2021. He admitted that withholding the cassette test data amounted to a misleading half truth. The Phase 2 report concluded that Arconic exploited the incompetence of the British Board of Agrément. The report stated that the certification body demonstrated an ingrained willingness to accommodate customers instead of insisting on high standards.

The Phase 2 report also criticized the Building Research Establishment. The government privatized the national building science center in 1997. The Inquiry found that the Building Research Establishment sacrificed rigorous application of principle to its commercial interests. The report stated that much of the work carried out by the organization was marred by unprofessional conduct and an absence of scientific rigor. This environment allowed manufacturers like Arconic to manipulate the testing processes.

Internal Knowledge and Confidentiality

Internal communications revealed that Arconic executives knew the product was unsafe. Technical manager Claude Wehrle sent multiple emails discussing the poor fire performance of the polyethylene core. In a 2010 email Wehrle told a colleague that the cassette variant did not meet the advertised European standard. He instructed his colleague that the shortfall must be kept very confidential.

In July 2015 Wehrle wrote another internal email stating that the polyethylene material is dangerous on facades. He recommended that everything should be transferred to fire retardant versions as a matter of urgency. This email circulated while contractors were installing the Reynobond PE 55 panels on Grenfell Tower. Wehrle refused to attend the Inquiry to give oral evidence. He a French blocking statute to avoid cross examination. The Phase 2 report concluded that Wehrle resorted to deliberate dishonesty to support the sale of the product.

During the February 2021 hearings Inquiry counsel Richard Millett questioned Claude Schmidt extensively. Millett asked Schmidt if he accepted that Arconic lied to customers by telling them the riveted version performed worse than the cassette version. Schmidt replied yes. The Inquiry heard that technical staff at Arconic were puzzled by the 2005 test failure. They believed competitors were not exhibiting similar problems. The management team decided that a Euroclass B classification was satisfactory without conducting further tests to confirm their assumptions.

Sales Tactics and Market Exploitation

Arconic maintained a sustained strategy to sell the combustible panels in the United Kingdom. United Kingdom sales manager Deborah French managed the Grenfell Tower account. The Inquiry heard that Arconic supplied the more flammable polyethylene panels by default as part of a marketing strategy. The fire retardant version cost more to produce.

In February 2014 Arconic instructed its sales staff to stop using the Class B classification for the product. Wehrle told the sales team that the fire rating of the polyethylene panels had been downgraded. French received this information did not inform her clients. She continued to use the defunct British Board of Agrément certificate to win sales. French sent the outdated certificate to the cladding subcontractors for Grenfell Tower two months after learning about the downgraded rating.

The Phase 2 report stated that French wittingly or unwittingly supported the company strategy to sell the product based on false claims. The Inquiry concluded that Arconic promoted and sold a product knowing that it presented a significant danger to the public. The company sought to exploit a weak regulatory regime in the United Kingdom to maximize profits.

Fire Test Performance Comparison

The following chart details the vast difference in fire performance between the two installation methods tested by Arconic in 2004 and 2005.

The Consequences of Concealment

The decision to withhold the cassette test data had fatal consequences. The architects and contractors working on the Grenfell Tower refurbishment relied on the British Board of Agrément certificate. They believed the Reynobond PE 55 panels were safe for a high rise building. The planning team at the local council required the panels to be installed in a cassette configuration for aesthetic reasons. The hidden rails provided a smoother appearance on the building exterior.

The panels performed exactly as they did in the 2005 fire test when the fire broke out on June 14 2017. The cassette configuration fueled the rapid spread of the flames up the side of the tower. The Phase 1 report previously identified the combustible cladding as the primary cause of the fire spread. The Phase 2 report places direct blame on Arconic for the presence of those panels on the building. The Inquiry stated that Arconic must take responsibility for the use of Reynobond PE 55 on Grenfell Tower. The company knew the sale was obtained using a certificate that gave a false impression of the product safety.

The findings from the Phase 2 report show the severe danger of allowing product manufacturers to control their own safety testing data. The report recommends the creation of a single independent regulatory body to oversee construction products and ensure accurate testing. The government and the police are currently reviewing the Inquiry findings to determine if criminal charges are appropriate for the corporate entities and individuals involved in the concealment.

20. What did the Phase 2 report conclude about the actions of these insulation manufacturers? The Phase 2 report concluded the manufacturers engaged in deliberate dishonesty.

The Kingspan K15 Deception

The Phase 2 report exposes a calculated strategy by Kingspan to market its K15 insulation for tall buildings using fabricated safety claims. Kingspan introduced a new chemical composition for K15 in 2006. The company continued to market the product using a successful fire test from 2005. The 2005 test evaluated the old chemical composition. Kingspan concealed this change from the market and from certification bodies.

Between 2007 and 2008, Kingspan conducted four large fire tests on the new K15 product. All four tests failed disastrously. Kingspan did not withdraw the product. The company kept the failed tests secret. Kingspan continued to sell K15 for use on buildings over 18 meters tall until October 2020. The Phase 2 report confirms Kingspan knowingly created a false market for combustible insulation.

Kingspan obtained a certificate from the Local Authority Building Control in 2009. This certificate contained false statements about the fire performance of K15. Kingspan used this document to distract buyers from the absence of valid test evidence. The company falsely claimed K15 achieved a Class 0 classification. Kingspan K15 made up 5 percent of the insulation used on the tower.

Kingspan executives understood the exact limitations of their K15 product. Internal documents revealed during the inquiry showed Kingspan managers openly discussing the disastrous results of the 2007 and 2008 tests. The new K15 formula burned violently during these assessments. Kingspan chose to bury these results. The company directed its sales teams to continue using the 2005 test data. This 2005 test evaluated a completely different system that included non combustible cement particle boards. Kingspan knew the 2005 test did not represent a typical external wall installation.

The Phase 2 report highlights how Kingspan exploited the absence of detailed knowledge within the construction industry regarding the BS 8414 testing standard. Kingspan relied on the fact that an unsuspecting market would accept its claims without demanding the underlying data. The company successfully created a false market for polymeric insulation on tall buildings. Kingspan maintained this deception for 14 years. The company only withdrew the misleading marketing claims in October 2020.

The Celotex RS5000 Manipulation

Celotex manufactured the majority of the insulation boards used during the refurbishment. The company launched RS5000 in August 2014 to compete directly with Kingspan. Celotex executives knew they needed a product certified for buildings over 18 meters tall. The Phase 2 report details how Celotex executed a dishonest scheme to mislead customers and the broader construction market.

Celotex tested RS5000 against the BS 8414 standard. The initial test failed. Celotex then rigged a second test. Employees added fire resistant magnesium oxide boards to the test rig in specific locations. These hidden boards protected the combustible insulation and allowed the system to pass the test. The Building Research Establishment oversaw this test. The Phase 2 report states the Building Research Establishment was complicit in this manipulation.

Celotex removed all

Interrogation of the Testing Facility Failures

2. What did the Phase 2 report conclude about this privatization? The report found the privatization left the facility open to manipulation by unethical manufacturers.

3. Which companies manipulated fire tests at the facility? Arconic, Celotex, and Kingspan manipulated the tests.

4. What specific insulation product did Celotex rig a test for in 2014? Celotex rigged the test for its RS5000 insulation.

5. How did Celotex rig the fire test for RS5000? The company secretly included fire resistant magnesium oxide boards in the test rig.

6. Did the testing staff know about the hidden magnesium oxide boards? Yes, the staff knew and deliberately omitted reference to them in the final report.

7. What did the Fire Brigades Union call the privatized testing facility? The union called it an utter mess and a complete disaster.

8. What did the Fire Brigades Union demand regarding the facility? The union demanded the government return the facility to public ownership.

9. Who wrote the report highlighting the severe absence of competence at the facility? Professor Luke Bisby wrote the report.

10. When did the facility conduct full size tests showing ACM panels burnt violently? The facility conducted these tests in 2001.

11. Did the facility warn the government about the 2001 ACM test results? The facility was reluctant to draw the government’s attention to the dangers.

12. What was the primary source of income for the facility after 1997? The facility relied on fees from the manufacturers whose products it tested.

13. What standard did the facility use that the Inquiry deemed too simplistic? The Inquiry criticized the BR 135 standard.

14. What full size fire test faced criticism for its limitations? The BS 8414 test faced heavy criticism.

15. How did the staff compromise their independence with Kingspan and Celotex? The staff advised the companies on how to satisfy safety criteria.

16. What percentage of the insulation on Grenfell Tower was made by Kingspan? Kingspan manufactured 5 percent of the insulation.

17. What certification body relied on withheld information to make inaccurate claims? The British Board of Agrément made inaccurate claims based on withheld data.

18. What did Arconic intentionally conceal regarding its cladding? Arconic concealed the full extent of the fire risks and poor test performance.

19. What was the original founding year of the facility before privatization? The government founded the facility in 1921.

20. What did the Phase 2 report say about the scientific rigor of the facility? The report stated the facility lost its scientific rigor and failed to maintain proper distance from clients.

The Privatization Penalty and Profit Motives

The Building Research Establishment began operations in 1921 as a public entity to test and certify building materials. The government privatized the organization in 1997. The Phase 2 report published on September 4 2024 confirmed this privatization forced the facility to rely on funding from the exact companies it was supposed to regulate. This financial dependence created a severe conflict of interest. The inquiry found the facility became entirely subservient to unethical manufacturers. Staff members prioritized fee income over life safety.

The report detailed how the facility lost sight of scientific rigor. Employees actively advised companies like Kingspan and Celotex on exactly how to pass safety criteria. This advisory role destroyed the independence of the testing house. Professor Luke Bisby served as an expert witness for the inquiry. He published findings showing a severe absence of competence across the organization. The Fire Brigades Union responded to these findings by demanding the immediate return of the facility to public ownership. Union general secretary Matt Wrack described the privatized entity as a complete disaster that bowed down to building material companies.

The Celotex RS5000 Deception

The most documented failure of the testing facility involved Celotex and its RS5000 insulation. In 2014 Celotex wanted to compete with Kingspan in the market for buildings taller than 18 meters. Celotex designed a dishonest scheme to pass the BS 8414 fire test. The company secretly installed fire resistant magnesium oxide boards behind the insulation during the test. These boards artificially stopped the fire from spreading.

The testing facility staff knew about the hidden magnesium oxide boards. Even with this knowledge the staff produced a final test report that deliberately omitted any mention of the fire resistant boards. The facility knew that revealing the boards would destroy the commercial viability of the RS5000 product. This manipulated report allowed Celotex to market the highly combustible insulation as safe for high rise buildings. The product eventually covered the walls of Grenfell Tower. The Phase 2 report explicitly condemned the testing facility for its complicity in this deception.

Arconic, Kingspan, and Buried Warnings

The testing facility also enabled deception by Arconic and Kingspan. Arconic manufactured the Aluminium Composite Material panels used on the tower. In 2001 the testing facility conducted full size fire tests on these exact types of panels. The tests showed the panels burned violently and caused catastrophic fire escalation. The facility failed to alert the government in plain terms. The reports drafted by the facility obscured the true danger to human life.

Arconic intentionally concealed the poor performance of its cladding from the market. The company withheld failed test data from the British Board of Agrément. This withholding caused the certification body to problem inaccurate safety claims. Kingspan manufactured 5 percent of the insulation used on Grenfell Tower. Kingspan also misled the market by withholding information about the limitations of its own products. The testing facility allowed these manufacturers to dictate the terms of their testing contracts. The facility only performed specific tasks requested by the clients. This subservience gave the industry total freedom to sell dangerous materials.

Flawed Standards and Regulatory Failures

The inquiry examined the specific testing standards used by the facility. The BR 135 standard assessed compliance for external thermal insulation. The Phase 2 report found this standard too simplistic. The standard provided a basic pass or fail result. The actual test data required complex interpretation that most industry professionals could not perform. The BS 8414 full size fire test also faced heavy criticism for its limitations.

The government relied on the testing facility for fire safety advice. The scope of this advice shrank massively after the 1997 privatization. The government lost access to independent scientific experience. The facility had a reputational investment in allowing overcladding solutions to proceed. The organization chose to mitigate fire risks on paper rather than prohibit dangerous materials entirely. This culture of accommodation directly enabled the disaster that killed 72 people.

Ignored Precedents and Historical Fires

The Phase 2 report highlighted multiple historical fires that should have served as warnings. The Knowsley Heights fire occurred in 1991. The testing facility investigated this fire. The inquiry found the facility had a commercial incentive to approve overcladding solutions rather than ban them. The facility wanted to appear as though it was managing the risks. The report called the failure to properly interrogate the Knowsley Heights fire a tragic missed opportunity.

The Garnock Court fire in 1999 and the Lakanal House fire in 2009 provided further evidence of cladding dangers. The facility investigated these fires failed to demand firm regulatory changes. The government contracted the facility to produce reports on real fires. The inquiry noted a complete absence of action on these reports. The findings were never connected to the development of new building regulations. The facility drafted its warnings in muted language that failed to convey the true threat to life.

The Fire Brigades Union Demands Accountability

The Fire Brigades Union reviewed the evidence presented to the inquiry. The union concluded the privatization of the testing facility directly caused the safety failures. Mark Rowe serves as the national officer for the union. He stated the facility was not fit for purpose because of its private ownership. He noted the facility was too to please clients and too reluctant to challenge the false information provided by manufacturers.

The union passed a motion instructing its executive council to lobby for the renationalization of the facility. The union stated the facility must operate for the public good rather than for profit. The inquiry heard evidence that the facility failed to share necessary safety information with other regulatory bodies. The private status of the organization encouraged secrecy to protect the commercial interests of paying clients.

14. What percentage of doors across the management stock had functioning self closers in February 2017? Internal estimates showed only 30 percent of doors had functioning self closers.

15. Who was responsible for health and safety compliance at the management organisation? Janice Wray held responsibility for health and safety compliance.

16. Who conducted the fire risk assessments for the management organisation? Carl Stokes conducted the fire risk assessments as a private contractor.

17. Did the fire risk assessments identify at risk residents? No. The assessments repeatedly recorded that no residents would struggle to hear a shouted warning.

18. How residents with disabilities lived in the tower? The inquiry heard that 52 flats had disabled occupants.

19. Did the management organisation have individualised evacuation plans for disabled residents? No. The organisation relied on a stay put policy and did not produce individualised evacuation plans.

20. What did the Phase 2 report say about the management culture? The report identified a culture of concealment where executives deliberately withheld fire safety information from the board.

The Toxic Atmosphere Between Management and Residents

The Kensington and Chelsea Tenant Management Organisation operated as the body appointed by the Royal Borough of Kensington and Chelsea to manage the council housing stock. The Phase 2 report published on September 4 2024 detailed a complete breakdown in trust between the management body and the people living in Grenfell Tower. The inquiry panel concluded that from 2011 to 2017 relations were characterised by distrust, dislike, personal antagonism and anger. The management organisation lost sight of the fact that the residents were people who depended on it for a safe and decent home. The report stated that the management body regarded occupants as a nuisance and failed to take their concerns seriously. The inquiry found that the management body viewed vocal residents as militant troublemakers. This created an unequal relationship where the public body exercising control over the building failed to treat residents with understanding and respect.

The Grenfell Action Group Warnings

Residents actively documented their safety concerns for years before the blaze. Edward Daffarn and Francis O’Connor ran the Grenfell Action Group blog. The blog highlighted dangerous living conditions and accused the management organisation of ineptitude. In November 2016 the group published a post stating that only a catastrophic event would expose the incompetence of their landlord and bring an end to the dangerous living conditions. The post predicted that a serious fire in a high density residential property was the most likely reason the management would be held accountable. The management organisation blocked the blog on its internal computer servers. When executives discussed the November 2016 blog post internally they chose to dismiss it. Barbara Matthews, a finance director, emailed colleagues stating she had spoken to chief executive Robert Black and they agreed to do nothing. The executives decided the blog was not the sort of website they should respond to. Peter Maddison, another executive, dismissed the blog as scaremongering and sought legal advice on whether the posts were libellous.

A Culture of Concealment Under Robert Black

Robert Black served as the chief executive of the management organisation from 2009 until after the fire. The Phase 2 report reserved severe criticism for his leadership. The inquiry panel identified a culture of concealment that started at the top of the organisation. Black and his executive team deliberately withheld important fire safety information from their own board and from the council scrutiny committee. In 2009 an independent report by Salvus Consulting Limited identified 19 breaches of the Fire Safety Order within the management organisation operations. Black failed to disclose these widespread failings to the board. The inquiry highlighted a pattern of Black withholding serious fire safety problems from his superiors. This included suppressing details about a previous fire at Grenfell Tower in 2010 where smoke spread from the ventilation system to eight floors and trapped residents in their homes. Black told the inquiry he did not recall having any direct personal interaction with resident groups regarding fire safety complaints. He later had to correct his written evidence after the inquiry presented multiple instances where the local councillor raised fire safety matters with him directly in 2012, 2013, 2015 and March 2017.

Ignored Complaints Regarding Broken Fire Doors

The management organisation received specific and repeated warnings about broken self closing devices on flat entrance doors. These devices are designed to pull doors shut automatically to prevent smoke and fire from spreading into communal hallways. In October 2015 a fire at Adair Tower, another block managed by the same organisation, resulted in an evacuation due to internal smoke spread. The London Fire Brigade issued an enforcement notice compelling the management to fix missing self closers. Residents at Grenfell Tower complained about the exact same defect. Edward Daffarn reported a jammed closing device on his door at Flat 136. The management told him to pull the door shut with force. The device remained broken and his flat was the on his floor to be affected by the fire. In November 2016 the London Fire Brigade served a deficiency notice listing fire safety defects at Grenfell Tower including broken self closers. At a management meeting in February 2017 the executive team reviewed a repairs report estimating that half of their flats did not have self closers. The report noted that 40 percent of the installed devices did not work. This meant only 30 percent of doors across the entire housing stock had functioning self closers. The management failed to rectify the defect before the blaze.

Failure to Protect At Risk Residents

The Phase 2 report exposed a complete failure to plan for the evacuation of residents with disabilities. The inquiry heard that 52 flats in Grenfell Tower had disabled occupants. On the night of the fire the document provided to the fire brigade only listed 10 disabled residents. Fifteen of the 37 at risk residents died in the fire. Janice Wray held responsibility for health and safety compliance at the management organisation. She relied on a private contractor named Carl Stokes to conduct fire risk assessments. In his six risk assessments of Grenfell Tower Stokes repeatedly recorded that there were no residents who would struggle to hear a shouted warning of fire. He made no further comments about at risk individuals. The inquiry concluded that his risk assessments were inaccurate and out of date. The management organisation relied entirely on a stay put policy. Teresa Brown, the director of housing, confirmed that individualised evacuation plans had not been produced for disabled residents. The London Fire Brigade had warned the management organisation about the absence of planning for residents with reduced mobility as early as 2009. The management discussed this warning at the highest level took no action to implement a formal documented system to assist at risk people during an evacuation.

Documented Timeline of Dismissed Warnings

The inquiry traced a chronological record of missed opportunities to prevent the disaster. The management organisation consistently chose inaction over resident safety.

Status of Self Closing Doors on June 14 2017

The failure to maintain self closing devices directly contributed to the spread of toxic smoke through the building. The data illustrates the condition of the flat entrance doors on the night of the fire based on post fire inspections and inquiry findings.

The management organisation allowed the building to degrade into a dangerous condition. The Phase 2 report confirmed that the tenant management body must take a share of the blame for the disaster. The organisation paid insufficient attention to matters affecting fire safety and ignored the people who lived in the tower. The Royal Borough of Kensington and Chelsea and its tenant management organisation issued apologies following the publication of the final report. The council leader Elizabeth Campbell stated the council would learn from every single criticism. The apologies arrived seven years after the fire and years after residents pleaded for safe living conditions.

widespread Oversight Failures in Building Control

The Royal Borough of Kensington and Chelsea Building Control department failed to perform its statutory function of ensuring the Grenfell Tower refurbishment complied with Building Regulations. The Phase 2 report published on September 4 2024 assigns considerable responsibility to the council. Building control officers waved through cladding that did not comply with fire safety regulations. They failed to properly scrutinize the design and choice of materials.

The surveyor responsible for the refurbishment was John Hoban. The inquiry found Hoban was overworked, poorly trained, and possessed a very limited understanding of the risks associated with aluminium composite material panels. He failed to obtain full information about the construction of the external wall at the design stage. The department relied entirely on certificates and assurances from contractors. They possessed insufficient expertise to assess complex high rise projects.

The report details a specific missed warning from 2001. The building control department knew about a major test involving aluminium composite panels with unmodified polyethylene cores. The panels burned violently during the test. The department failed to pay due regard to these clear results. They took no steps to ascertain the extent to which such panels were in use. They failed to publish the results or warn the construction industry about the risks.

The Kensington and Chelsea Tenant Management Organisation managed the building and directed the refurbishment. The inquiry found the organization treated the demands of managing fire safety as an inconvenience. Chief Executive Robert Black established a pattern of concealment in relation to fire safety matters. Black consistently failed to inform the board or the council about the London Fire Brigade’s concerns regarding compliance with the Fire Safety Order.

The initial motive for cladding Grenfell Tower was purely aesthetic. The Tenant Management Organisation wanted to improve the physical appearance of the tower to prevent it from looking like a poor relation to a nearby building. Architects from Studio E initially wanted to use non combustible zinc panels. The Tenant Management Organisation pressured the architects to switch to aluminium composite material to reduce costs. This decision saved £293, 368 on a £9. 2 million refurbishment.

The Tenant Management Organisation never completed an approved fire safety strategy. They failed to ensure key fire protection measures functioned properly. The fire risk assessments carried out by the organization failed to identify the flammability of the external cladding system. Assessors relied entirely on visual inspections and ignored known dangers. They failed to account for the needs of residents and did not consider alternative evacuation plans beyond the stay put policy.

The fire risk assessments conducted by the Tenant Management Organisation were entirely deficient. Assessors missed the insufficient fire door protection throughout the building. They failed to recognize the absence of proper evacuation strategies for residents. This superficial method led to the omission of severe fire safety risks. The organization ignored known dangers and allowed dangerous conditions to remain. The inquiry criticized both the Tenant Management Organisation and the council for not responding to the fire risk assessments in a timely and manner. The assessments did not account for the needs of residents with mobility problems or disabilities. They did not consider alternative evacuation plans. This failure left residents completely unprotected during the fire.

The Phase 2 report also examined the role of private building control inspectors. The National House Building Council is the largest private building control inspector in the United Kingdom. The inquiry found the organization failed to ensure its building control function remained regulatory and free of commercial pressures. The council was unwilling to upset its customers and the wider construction industry. They chose not to reveal the extent of the use of combustible insulation in the external walls of high rise buildings. This behavior directly contradicted statutory guidance. The failure of both public and private building control entities created an environment where safety was routinely sacrificed for commercial convenience.

The Phase 2 report heavily criticized the architects at Studio E. The firm bore heavy responsibility for the disaster. The inquiry described their behavior as cavalier. They failed to meet the standards of a reasonably competent architect. Studio E instructed a consultant named Exova to prepare a fire safety strategy for the refurbished building. Exova failed to complete this strategy. The building control department failed to notice the absence of this required documentation. Everyone involved in the choice of the materials for the external wall thought the responsibility for their suitability and safety lay with someone else. This culture of buck passing defined the relationship between the contractors and the council. The building control officers accepted incomplete plans and never demanded the finalized fire safety strategy before approving the construction phases.

Following the fire, the council failed to provide proper emergency accommodation for survivors. The report states the council abandoned survivors without information. On November 5 2024, the Royal Borough of Kensington and Chelsea issued a formal apology. The council accepted the findings of the Phase 2 report. They admitted their initial evidence to the inquiry regarding the building control service did not cover the full extent of its failures. The council acknowledged a breakdown in relationships with residents characterized by disrespect and indifference. They admitted an absence of professional competence in building control and emergency planning. The council stated they have since implemented the recommendations of the Phase 1 report, brought housing services back in house, and established a dedicated in house fire safety team. They also instituted a complete ban on the use of any combustible materials in external walls for all council construction and refurbishment projects, regardless of building height.

20. Did the architects understand the Building Regulations? Studio E demonstrated a cavalier attitude toward the regulations affecting fire safety.

The Financial Engineering of a Disaster

The Grenfell Tower Inquiry Phase 2 report published on September 4 2024 details the exact financial decisions that placed combustible materials on the exterior of the building. The Kensington and Chelsea Tenant Management Organisation managed the refurbishment budget. The initial plans for the refurbishment exceeded the budget by a significant margin. The organization shifted its focus entirely to saving cost by May 2013. This financial pressure dictated the selection of the primary contractor and the materials used for the exterior cladding.

The organization implemented a formal procurement process to select a principal contractor. Rydon Maintenance Limited submitted the most competitive tender. The Rydon tender still exceeded the budget. The organization received legal advice stating it would be improper to negotiate before the procurement process concluded. The organization ignored this advice. The organization entered into secret discussions with Rydon to agree on a reduced price. Rydon secured the contract by agreeing to lower the in total cost to an acceptable level.

Studio E Architects and the Material Switch

Studio E Architects served as the principal architect for the refurbishment. The firm originally specified zinc rainscreen panels for the exterior. Cost became the primary driver for the Tenant Management Organisation. The organization demanded cheaper alternatives. Rydon offered a substantial saving by switching the exterior panels. Rydon proposed using an aluminium composite material instead of zinc. The specific product chosen was Reynobond 55 PE. The PE stands for polyethylene. Polyethylene is a highly combustible plastic.

The Phase 2 report confirms that Rydon secured these savings through its relationship with Harley Facades. Harley Facades acted as the cladding subcontractor. The decision to use aluminium composite panels with unmodified polyethylene cores was primarily responsible for the rapid spread of the fire. The report states that Studio E failed to recognize that the aluminium composite material was dangerous. The architectural firm failed to warn the Tenant Management Organisation against its use. The inquiry concluded that Studio E fell well the standard expected of a reasonably competent architect.

The Failure to Check Designs and Materials

The inquiry identified multiple areas where Studio E failed to meet basic professional standards. The firm failed to ensure that the fire engineering consultancy Exova completed the fire safety strategy for the refurbished building. Studio E failed to advise Rydon or the Tenant Management Organisation that a completed fire safety strategy was required. Studio E failed to understand its responsibility for design work carried out by subcontractors. The firm did not check the designs submitted by Harley Facades to ensure the building would comply with Building Regulations upon completion.

Studio E also failed to devise a proper fire stop strategy. The firm failed to check the fire stop designs produced by Harley Facades. Studio E failed to produce detailed drawings of the window reveals. The firm failed to notice that the materials specified for the window infill panels were unsuitable. Studio E failed to recognize that the Celotex insulation specified for the project was combustible. The firm failed to recognize that the insulation was not suitable for use on a building over 18 metres in height. The report states that Studio E bears a very significant degree of responsibility for the disaster.

Rydon and the Casual Method to Fire Safety

The Phase 2 report directs severe criticism at Rydon Maintenance Limited. Rydon failed to perform its role as the primary contractor properly. Rydon assured the Tenant Management Organisation that the completed refurbishment would comply with Building Regulations. The completed building did not comply. The inquiry found that Rydon did not give sufficient importance to the safety of the building occupants. Rydon displayed a casual attitude to fire safety throughout the entire project.

The report details how Studio E, Rydon, and Harley Facades all took a casual method to contractual relations. The firms did not properly understand the nature and scope of the obligations they had undertaken. The firms paid scant attention to their contracts. The firms failed to identify their own responsibilities for important aspects of the design. Each firm assumed that someone else was responsible for matters affecting fire safety. Everyone involved in the choice of the materials for the external wall thought that responsibility for their suitability and safety lay with someone else.

The Absence of Technical Expertise

The inquiry found that none of the firms involved in the design of the external wall acted in accordance with the standards of a reasonably competent person. The personnel at Studio E, Rydon, and Harley Facades were not familiar with the relevant provisions of the Building Regulations. The personnel did not understand Approved Document B or industry guidance. Studio E demonstrated a cavalier attitude to the regulations affecting fire safety. Rydon and Harley Facades relied on their previous experience rather than on any technical analysis or expertise.

The risks of using combustible materials in the external walls of high rise buildings were well known in the industry. The report states that the firms should have been aware of these dangers. The failure to ensure the involvement of a fire engineer after the appointment of Rydon as principal contractor was one of the most serious flaws in the design and execution of the refurbishment. The report concludes that Rydon bears considerable responsibility for the fire.

Financial Savings Versus Life Safety

The inquiry exposes a culture where cost cutting and profit margins took priority over safety and quality. The decisions taken during the refurbishment process were driven by financial considerations rather than concern for the wellbeing of residents. The Tenant Management Organisation manipulated the procurement process to save money. Rydon secured the contract by offering cheaper combustible materials. Studio E failed to challenge the use of these dangerous materials. Harley Facades installed the materials without verifying their safety.

The Phase 2 report provides specific data regarding the savings achieved by switching materials. The exact financial figures demonstrate the minimal savings that led to the use of highly combustible cladding. The table outlines the cost differences between the proposed zinc panels and the chosen aluminium composite material panels based on the inquiry findings.

The financial data shows that the Tenant Management Organisation saved less than half a million pounds by switching to the combustible aluminium composite material. This decision directly caused the rapid spread of the fire. The Phase 2 report confirms that the unmodified polyethylene in the panels was the principal factor in the rapid growth of the fire. The insulation boards behind the panels also contributed to the rate and extent of vertical flame spread due to their heat retaining ability.

The Role of Harley Facades in the Cladding Failure

The Phase 2 report places significant blame on Harley Facades. The firm acted as the specialist cladding subcontractor. Harley Facades failed to ensure that the materials used in the external wall were safe. The firm installed the Reynobond 55 PE panels without questioning their suitability for a high rise residential building. The personnel at Harley Facades did not understand the Building Regulations governing fire safety. The firm relied entirely on the manufacturers and the building control department to verify the safety of the products.

Harley Facades also failed to design and install fire stops correctly. Fire stops are essential components designed to stop fire from spreading through the gaps between the original building wall and the new cladding. The inquiry found that the fire stops installed at Grenfell Tower were defective. The stops failed to perform their intended function. The poor design and installation of these stops allowed the fire to escape from the flat of origin and ignite the highly combustible aluminium composite material panels.

The Failure of Building Control

The Royal Borough of Kensington and Chelsea building control department served as the last line of defense. The department had a statutory obligation to ensure that the refurbishment complied with the Building Regulations. The Phase 2 report concludes that the department failed in this duty completely. The building control officers failed to properly scrutinize the design of the external wall. The officers failed to question the choice of materials. The officers failed to obtain the necessary information to assess the fire safety of the cladding system.

The inquiry found that the building control department issued a completion certificate for Grenfell Tower even though the building was in a dangerous condition. The department bears considerable responsibility for the disaster. The failure of the building control officers to identify the obvious regulatory breaches allowed the deadly cladding system to remain on the building. The Phase 2 report states that the building control department failed to protect the residents of Grenfell Tower from the fatal consequences of the cost cutting decisions made by the Tenant Management Organisation and the contractors.

The Chain of Incompetence

The Phase 2 report describes the choice of combustible materials as the result of a series of errors caused by the incompetence of the organizations and individuals involved. The architectural firm failed to design a safe building. The principal contractor failed to build a safe building. The cladding subcontractor failed to install safe materials. The Tenant Management Organisation failed to oversee the project properly. The building control department failed to identify the regulatory breaches.

The inquiry findings show a complete breakdown of responsibility. The firms involved in the Grenfell Tower refurbishment operated in silos. The firms assumed that compliance and safety were the duties of other parties. This assumption proved fatal. The Phase 2 report establishes that the disaster was not an accident. The disaster was the direct result of calculated financial decisions and professional incompetence by Studio E Architects and Rydon Maintenance Limited.

Phase 2 Report Interrogation: The British Board of Agrément

Commercial Interests Over Life Safety

The Grenfell Tower Inquiry Phase 2 report published on September 4 2024 exposes the British Board of Agrément as a central enabler of the disaster. The organization operates as a commercial entity that certifies construction products for compliance with building regulations. The Inquiry found that the board prioritized customer satisfaction over rigorous safety testing. This business model allowed product manufacturers to secure misleading certificates for highly combustible materials used on Grenfell Tower.

The report details how the board failed to verify the claims made by Arconic regarding its Reynobond 55 PE cladding panels. Arconic obtained a certificate from the board in 2008. The certificate stated the panels could be regarded as having a Class 0 surface in England and Wales. The board issued this certificate based on a 2005 fire test. That test expired five years later. Arconic subsequently conducted new tests in 2011. The riveted form of the panels achieved a Class B rating. The cassette form achieved a Class E rating. Arconic deliberately withheld the Class E rating from the board.

The board initiated a review of the Reynobond 55 PE certificate in 2014. Arconic ignored repeated requests for updated information. A former project manager at the board testified during the Inquiry that she proceeded with the review using only publicly available information. The board reissued the certificate in 2015 without confirming any changes to the product design or fire performance. The Inquiry concluded that the board produced a materially wrong certificate because its staff possessed poor technical expertise and an ingrained willingness to accommodate customers.

Testimony Exposes Certification Flaws

The Inquiry heard extensive testimony regarding the internal operations of the British Board of Agrément. Valentina Amoroso worked as a project manager at the board. She took over the review of the Reynobond 55 PE certificate in November 2014. Her predecessor attempted to contact Arconic multiple times between October 2013 and May 2014. Claude Wehrle served as a technical manager at Arconic. He responded to the board failed to provide the necessary test data. Amoroso testified that she could not obtain the required information from Arconic. She emailed the company in January 2015 to confirm the board would proceed using information already in its possession. Amoroso admitted during the Inquiry that this decision carried significant risk. She acknowledged that the board moved forward without confirming any changes in the product specification that would invalidate the certificate.

The Inquiry found that Arconic executives knew the Reynobond 55 PE panels performed poorly in fire tests. Wehrle showed colleagues pictures of an aluminum composite material fire in Romania in 2009. He used the pictures to demonstrate the dangers of polyethylene filled sheets. Wehrle told a colleague in 2010 that the product performed worse in fire when folded into a cassette form. He instructed the colleague to keep this information very confidential. Arconic deliberately concealed this reality from the board. Deborah French worked as a salesperson for Arconic in the United Kingdom. She sent the outdated certificate to the cladding subcontractor for Grenfell Tower. The Inquiry determined that Arconic executed a sustained strategy to sell the product based on false statements.

The Insulation Certificates

The Phase 2 report also condemns the board for its handling of certificates for insulation products. Kingspan manufactured K15 insulation. The board issued a certificate for K15 without assessing its manufacture, testing, or fire performance. The Inquiry found that the board allowed Kingspan to dictate the contents of the certificate. The board did not obtain any test data relating to K15 before stating the product achieved a national Class 0 classification. Kingspan used this flawed certificate to create a false market for K15 on buildings over 18 meters in height.

The Phase 2 report outlines how Kingspan exploited the certification process to dominate the insulation market. Kingspan introduced a new technology for K15 in 2006. The company continued to market the product using test data from a 2005 test performed on an older version of the product. The 2005 test included a non combustible cement particle board as the rainscreen. Kingspan conducted new tests on the updated K15 product between 2007 and 2008. These tests resulted in disastrous fire performance. Kingspan decided to mask the absence of supporting test evidence. The company relied on the fact that the market would trust the certificate issued by the board. The board directed buyers to consult Kingspan for advice on using the product on buildings over 18 meters. This arrangement allowed Kingspan to control the narrative and sell an unsafe product to an unsuspecting market.

Celotex observed the commercial success of Kingspan and decided to copy its methods. Celotex launched RS5000 in August 2014. The company wanted to market the product as suitable for buildings over 18 meters. Celotex tested the product in May 2014. The company secretly added magnesium oxide boards to the test rig to ensure a pass. Celotex then marketed RS5000 as the polyisocyanurate board to successfully pass the required fire test. The board accepted the claims made by Celotex without demanding complete transparency regarding the test configuration. The Inquiry found that the board failed to manage the conflict between its commercial interests and the need for rigorous independence.

United Kingdom Accreditation Service Failures

The United Kingdom Accreditation Service holds responsibility for overseeing certification bodies like the British Board of Agrément. The Phase 2 report assigns heavy blame to the accreditation service for failing to apply proper standards of monitoring and supervision. The service assessed the board only once between 2008 and 2016. The Inquiry noted that the service failed to meet its own requirements for assessment during that period.

The report states that the accreditation service did not perform examinations of the processes used by the board to produce individual certificates. The service only checked whether the board followed the steps outlined in its contracts with customers. This superficial oversight allowed the board to continue issuing misleading certificates without detection. The Inquiry concluded that the ability of three separate manufacturers to obtain misleading certificates points to a serious failure of the entire certification system.

Timeline of Certification Failures

Post Fire Actions and Certificate Withdrawals

The British Board of Agrément continued to mishandle certificates even after the Grenfell Tower fire on June 14 2017. Arconic informed the board that it would not discontinue the production of Reynobond 55 PE because the product had non high rise uses. The board sent Arconic a redrafted certificate that included a new clause stating the product should not be used higher than 18 meters. The redrafted certificate still falsely claimed the standard polyethylene cored version of the product obtained a Euroclass B rating.

The board withdrew the Reynobond certificate in May 2019. The board blamed a failure by Arconic to provide requested technical data as the reason for the withdrawal. The Inquiry revealed that the board only discovered the true test data through a supplementary report submitted by an expert witness to the Inquiry. The board released a statement following the publication of the Phase 2 report indicating it would review the findings in detail and that the findings would serve as a significant focus for the organization.

16. What did the report conclude about the risk assessments conducted by the London Fire Brigade? The report found the agency failed to obtain necessary information to conduct proper risk assessments.

17. When did the fire inspectorate last evaluate the London Fire Brigade before the Phase 2 report publication? The inspectorate evaluated the agency in February 2024 and June 2024.

18. What specific recommendation was directed solely at the London Fire Brigade? The report recommended creating systems to gather and implement lessons from previous incidents.

19. How did the report describe the understanding of risk among incident commanders? The report identified a fundamental misunderstanding of risk within modern buildings.

20. What national body was recommended to review how firefighters carry out instructions? The report recommended the National Fire Chiefs Council review these arrangements.

Institutional Shortcomings in Incident Command

The Phase 2 report published on September 4 2024 detailed severe institutional failures within the London Fire Brigade. The inquiry found that the agency failed to learn from the 2009 Lakanal House fire. The report stated that the agency did not adapt its training or operational policies to handle complex high rise fires. Incident commanders at Grenfell Tower demonstrated a fundamental misunderstanding of risk within modern buildings. The agency relied on standard firefighting that assumed building compartments would contain the fire. When the external cladding ignited, the command structure collapsed.

The report criticized the agency for its strict adherence to the stay put policy. Firefighters and control room operators continued to tell residents to remain in their flats long after the fire breached compartmentation. The inquiry concluded that this rigid adherence to a failed strategy led to preventable deaths. The agency failed to obtain necessary information through inspections to conduct proper risk assessments. A proper risk assessment would have alerted commanders to the danger and prompted a change in response tactics.

The inquiry found that the operational command structure did not allow information and orders to flow properly. Commanding officers could not use information from the ground to conduct risk assessments. They also could not transmit orders to change the strategy. The report noted that the agency did not have the educational foundation to train professionals for such complex events.

Control Room Breakdowns and Technological Failures

The Phase 2 report exposed severe operational problems within the London Fire Brigade control room. Between 2013 and the Grenfell Tower fire in 2017, control room staff did not receive the full day of fire survival guidance refresher training. The Lakanal House Board had planned and approved this training, and the agency had promised it to the coroner. The control room suffered from major staffing problems and underwent constant restructuring between 2009 and 2017.

Technological failures worsened the human errors. The Vision mobilising system, provided by Capita, experienced severe instability. For several years after its introduction, the Vision system suffered from serious faults. Operators reported more than 500 faults to Capita in the six months alone. The system failed completely on six occasions during its year, forcing operators to use pen and paper for periods ranging from 40 minutes to three hours. These technological breakdowns left control room staff unprepared to handle the volume of emergency calls on June 14 2017.

The inquiry found that senior officers knew about the consistent failure to provide fire survival guidance training. They allowed the problems with the Vision system to crowd out other essential training. The report stated that the importance of fire survival guidance refresher training cannot be overstated. The absence of this training left operators unable to give appropriate advice to trapped residents when the stay put policy failed.

Phase 2 Recommendations and Agency Response

The Phase 2 report issued 58 recommendations, with 13 specifically related to the London Fire Brigade. The inquiry directed one recommendation solely at the agency, requiring it to create systems to gather, review, and implement lessons from previous incidents, inquests, and investigations. The report directed three recommendations at His Majesty Inspectorate of Constabulary and Fire and Rescue Services. These recommendations required the inspectorate to evaluate the control room coordination, training needs, and general operational planning of the agency.

London Fire Commissioner Andy Roe published a formal response accepting all recommendations. The agency stated it had already completed all recommendations from the Phase 1 report. The agency introduced a new fire survival guidance app and software that enables the public to share a live video feed of the incident with the control room. The inspectorate evaluated the agency in February 2024 and June 2024, noting improvements in performance and risk understanding.

Water Management and Radio Communications

The Phase 2 report identified severe operational deficiencies that extended beyond the London Fire Brigade to affect all fire and rescue services nationwide. The inquiry directed five specific recommendations to all national fire services, focusing heavily on radio communications and water management at active incidents. During the Grenfell Tower fire, firefighters experienced widespread radio communication failures. Thick concrete walls and the size of the incident blocked radio signals, leaving crews inside the tower unable to communicate with the command center outside.

The report also detailed severe problems with water supply management. Firefighters struggled to maintain adequate water pressure to fight the blaze on the upper floors. The inquiry recommended that the British Standards Institution revise the BS750 standard for water supply. The London Fire Brigade specialist water team began discussions with the institution promptly following the report publication to address these infrastructure weaknesses.

To ensure national consistency, the report called for the creation of a College of Fire and Rescue. This new institution would set national standards for firefighter deployment and interagency communication. The National Fire Chiefs Council received a mandate to review how firefighters carry out instructions during live incidents. The London Fire Brigade offered its help to the council for this review, referencing its experience in handling high risk emergencies.

Recommendation Distribution for Fire Services

The Phase 2 report distributed its 13 fire service recommendations across multiple entities to ensure accountability.

The Size of the Remediation Backlog

The Grenfell Tower Inquiry Phase 2 report exposed decades of regulatory failure. The physical manifestation of this failure is a nationwide backlog of unsafe buildings. Data published by the Ministry of Housing, Communities and Local Government in January 2025 reveals the exact scope of the ongoing emergency. As of December 31 2024, the department identified 5, 011 residential buildings measuring 11 metres and over in height with unsafe cladding.

The progress on making these buildings safe remains slow. Out of the 5, 011 identified buildings, only 1, 472 have completed remediation. This means 29 percent of the known inventory is safe. Another 931 buildings have started remediation works. The largest category consists of 2, 608 buildings that have not even begun remediation. Over half of the known unsafe buildings in England sit untouched.

The true volume of the problem extends beyond the 5, 011 monitored buildings. A March 2025 report from the Public Accounts Committee indicates that as as 7, 000 unsafe buildings over 11 metres are still to be identified. The total number of buildings requiring remediation is estimated to be between 9, 000 and 12, 000. The financial cost to fix these buildings is massive. The central estimate for remediating all affected buildings is £16. 6 billion, with the upper range reaching £22. 4 billion.

Government Funding and Financial Caps

The Westminster government established several funding structures to assist leaseholders. The Building Safety Fund covers buildings 18 metres and over in height. The Cladding Safety Scheme covers buildings between 11 and 18 metres. By October 31 2024, the Building Safety Fund had paid out £1. 742 billion.

The government plans to cap taxpayer contributions towards cladding remediation at £5. 1 billion over the lifetime of its remediation programmes. This cap creates a massive funding gap when compared to the £16. 6 billion central estimate for total remediation costs. The government intends to force developers to cover the remaining costs. The Building Safety Act 2022 introduced legal protections to shield leaseholders from paying for remediation, shifting the financial liability to building owners and developers.

Even with these legal protections, the pace of funding approval and work commencement is sluggish. The Public Accounts Committee noted that almost eight years after the Grenfell disaster, work had yet to start on over half of the 5, 000 buildings in the government portfolio.

Developer Remediation Contracts

The government pressured major housing developers to sign remediation contracts. As of November 30 2024, 54 developers signed the developer remediation contract. These contracts cover 4, 683 buildings. Within this group, developers identified 1, 746 buildings as having serious fire safety risks requiring remediation.

Progress among developers is heavily delayed. Out of the 1, 746 buildings with serious risks, developers reported that only 439 had completed remediation by November 2024. This represents just 25 percent of the buildings they are responsible for fixing. Data from specific developers shows the granular delays. A September 2024 review of Barratt Developments showed 262 buildings across 92 developments were under review or expected to require remediation. At that time, 63 percent of Barratt buildings identified for self remediation had not yet started works.

The Remediation Acceleration Plan

In December 2024, the government published the Remediation Acceleration Plan. The plan sets a deadline of 2029 for completing remediation on all high rise buildings over 18 metres. It also mandates completing remediation for all buildings between 11 and 18 metres by 2031. The government threatened landlords with severe penalties if they fail to meet these deadlines.

Industry experts and parliamentary committees immediately questioned the feasibility of these deadlines. The Public Accounts Committee stated that the Remediation Acceleration Plan is insufficiently ambitious and at risk of not delivering what is promised. The construction sector faces severe labour constraints. The government pledged £600 million in March 2025 to train 60, 000 construction workers by 2029, existing labour deficits make the required ramp up highly difficult.

The Human Cost of Delays

The statistics represent a massive human toll. The Public Accounts Committee estimates that the cladding emergency affects up to 3 million people. Residents continue to suffer severe financial difficulties and emotional distress while they wait for their homes to be made safe. struggle to pay exorbitant insurance costs. These insurance premiums frequently remain high even after remediation works are completed.

Leaseholders are trapped in unsellable homes. The presence of unsafe cladding makes it impossible to secure mortgages for prospective buyers. The UK six largest lenders confirmed in December 2022 that they lend on properties needing cladding remediation, the practical application of this policy remains uneven. The physical danger is also real. In August 2024, a fire broke out in a residential block of flats in Dagenham. The building was undergoing remedial works to replace non compliant cladding at the time of the fire.

Social Housing Sector Remediation

The social housing sector also faces a massive backlog. As of November 30 2024, the government identified 2, 606 social buildings measuring 11 metres and over in height with serious fire safety cladding defects. Out of these, 1, 176 buildings are reported to have started or completed remediation works. This leaves over half of the identified social housing stock waiting for safety upgrades.

The government changed its reporting methodology in June 2024 to include social housing buildings that completed remediation independently of government funding. This administrative change artificially boosted the completion numbers, the physical reality on the ground remains dire for thousands of social housing tenants.

Local Authority Enforcement Action

The government granted local authorities the power to force building owners to remediate unsafe cladding under the Housing Act 2004. Progress on enforcement remains limited compared to the volume of the backlog. As of December 12 2024, local authorities took or were taking enforcement action against 506 buildings over 11 metres with unsafe cladding.

This enforcement figure represents a small fraction of the 2, 608 buildings that have not started remediation works. The data only reflects formal action taken by local councils. It does not account for the thousands of buildings where owners face no immediate legal pressure to begin physical works. The absence of widespread enforcement allows building owners to delay expensive safety upgrades indefinitely.

Aluminium Composite Material Remediation

Aluminium Composite Material is the specific type of cladding that caused the rapid fire spread at Grenfell Tower. The government prioritised the removal of this specific material. As of December 31 2024, the department identified 514 high rise residential and publicly owned buildings with Aluminium Composite Material cladding systems.

Progress is highest in this specific category. Out of the 514 buildings, 446 have completed remediation. Another 46 buildings have started works. This leaves a small fraction of buildings that have not started works. It took over seven years to reach an 87 percent completion rate for the exact material that caused the Grenfell disaster.

National Remediation Status Data

The following chart visualises the remediation status of the 5, 011 identified buildings over 11 metres in England as of December 31 2024.

The data shows a clear failure to execute timely safety upgrades. The government relies on developers to self remediate, the pace is entirely insufficient. The £5. 1 billion taxpayer cap guarantees that funding disputes continue to delay physical works. The 2029 and 2031 deadlines set by the Remediation Acceleration Plan appear mathematically impossible given the current run rate of completions and the estimated 7, 000 buildings yet to be identified.

Section 11: The Social Housing Divide and Building Safety Remediation Data

Grenfell Tower Inquiry Phase 2 Report Interrogation: Social Housing Data

7. How public sector housing structures recorded lethal fire safety cladding defects by late 2024? The Ministry of Housing Communities and Local Government identified 2606 social buildings by December 2024.

8. What percentage of these 2606 social buildings started or finished remediation by December 2024? Official data shows 45 percent or 1176 buildings reached this stage.

9. How social housing structures remained untouched by remediation at the end of 2024? A total of 1430 buildings saw no remediation progress.

10. Did the number of defective social housing structures increase in 2025? Yes. The total reached 2657 by March 2025 and 2805 by July 2025.

11. What height threshold applies to the monitored social housing structures? The data tracks buildings measuring 11 metres and over.

12. Which government department publishes the Building Safety Remediation monthly data? The Ministry of Housing Communities and Local Government publishes the statistics.

13. How dwellings sit within unsafe monitored buildings across all sectors? The department estimates 280000 dwellings remain in monitored buildings.

14. What percentage of the 2657 defective social buildings identified by March 2025 started or finished remediation? The March 2025 data records 43 percent or 1148 buildings in this category.

15. How registered providers of social housing reported responsibility for buildings over 11 metres by March 2025? The data shows 432 providers reported responsibility.

16. What proportion of all social housing structures over 11 metres have lethal fire safety defects? The March 2025 survey confirms 15 percent of these structures contain defects.

17. How does the social housing remediation rate compare to the private sector developer remediation rate? Developers reported 49 percent started or finished by December 2024. Social housing trailed at 45 percent.

18. What scheme funds the remediation of buildings between 11 and 18 metres? The Cladding Safety Scheme provides the funding.

19. How social housing structures finished remediation works prior to their most recent building works assessment by late 2024? The December 2024 data identifies 123 buildings in this specific category.

20. What percentage of social housing structures with defects had no clear remediation plans by December 2024? The data shows 18 percent or 477 buildings operated in the absence of clear plans.

21. How social housing structures had plans in place had not started remediation by December 2024? The records show 960 buildings representing 37 percent fell into this group.

22. What primary defect does the Building Safety Remediation data monitor? The data tracks lethal fire safety cladding defects related to the external wall system.

23. Did the government change the method for reporting social housing remediation in 2024? Yes. From June 2024 the department included buildings remediated independently of government funding.

24. How tall buildings in the Building Safety Fund finished alternative cladding remediation by December 2024? The fund recorded 364 buildings or 45 percent as finished.

25. What enforcement action appears in the monthly data releases? The releases track local authority enforcement action under the Housing Act 2004.

26. How social sector structures applied to the Cladding Safety Scheme by late 2025? An additional 1300 buildings progressed through eligibility checks by December 2025.

The Grenfell Tower Inquiry Phase 2 report exposes a severe divide in how quickly public sector buildings receive life saving repairs. The Ministry of Housing Communities and Local Government publishes Building Safety Remediation data every month. The December 2024 release confirms 2606 social buildings measuring 11 metres and over contain lethal fire safety cladding defects. By March 2025 this number climbed to 2657 buildings. By July 2025 the figure reached 2805 buildings. The data proves that a massive portion of the social housing sector remains unsafe years after the Grenfell disaster.

Registered providers of social housing bear responsibility for these structures. The December 2024 statistics show that only 1176 of the 2606 identified social buildings had started or finished remediation works. This represents exactly 45 percent. The remaining 1430 buildings saw zero physical progress. Among those untouched buildings 477 operated in the absolute absence of any clear remediation plan. Residents inside these 477 towers go to sleep every night surrounded by combustible materials. The government data confirms these residents have no scheduled date for their homes to become safe.

A direct comparison between private developers and social housing providers reveals a distinct gap. The December 2024 data shows private developers committed to remediating 1745 buildings. Developers reported that 49 percent of their buildings had started or finished remediation. Social housing providers trailed behind at 45 percent. The March 2025 data release shows the social housing completion rate actually dropped to 43 percent due to newly discovered defective buildings entering the registry. The numbers prove that public sector residents wait longer for basic fire safety corrections than private sector residents.

The financial mechanics behind this delay point directly to government funding decisions. Prior to June 2025 social housing providers faced strict eligibility rules for the Cladding Safety Scheme. providers had to self fund the removal of combustible external wall systems. The January 2026 data release shows 563 social buildings relied entirely on self funded remediation by registered providers. When social landlords drain their own budgets to remove lethal cladding they frequently delay other essential maintenance. The Westminster government designed a funding model that forced social housing providers to compete for limited resources while private developers received structured government contracts.

The human cost of this administrative failure is measurable. The Ministry of Housing Communities and Local Government estimates that 280000 dwellings sit within unsafe monitored buildings across all sectors. A massive percentage of these dwellings belong to the social housing sector. The July 2025 data confirms 2712 buildings across all sectors remain completely unremediated. The residents inside these buildings endure continuous anxiety. They rely on waking watch patrols and temporary fire alarms. The government data tracks the progress of the Waking Watch Relief Fund the numbers confirm that temporary measures outlast their intended timelines.

Building Safety Remediation Progress in Social Housing

The Building Safety Remediation data exposes a severe regulatory failure. The Regulator of Social Housing requires landlords to submit fire safety remediation data at a building level. The March 2025 survey confirms that 15 percent of all social housing buildings over 11 metres contain lethal external wall system defects. This means that out of 17391 social buildings reported by 432 providers 2657 require major construction work to prevent another Grenfell disaster. The sheer volume of defective buildings overwhelms the available construction workforce. The government data shows a bottleneck in the remediation pipeline.

Local authorities possess the power to take enforcement action under the Housing Act 2004. The monthly data releases track this enforcement activity. The statistics show that local authorities rarely use their full enforcement powers against registered providers of social housing. The government prioritises enforcement against private freeholders while allowing social landlords extended timelines to secure funding. This dual standard leaves social housing residents trapped in dangerous buildings for longer periods. The Grenfell Tower Inquiry Phase 2 report explicitly condemned the culmination of decades of failure by central government. The current remediation data proves that this failure continues today. The data confirms that local councils hesitate to prosecute their own housing departments or affiliated housing associations. This hesitation creates a protected class of landlords who face zero legal consequences for maintaining lethal buildings.

The data from late 2025 shows minimal improvement. The December 2025 release indicates the government began migrating data to the National Remediation System. During this migration the department admitted that 1300 social sector buildings had applied to the Cladding Safety Scheme and were still progressing through eligibility checks. These 1300 buildings represent thousands of residents waiting for bureaucratic approval before construction can even begin. The paperwork delays the physical removal of combustible materials. The government requires extensive surveys and financial audits before releasing funds. These administrative requirements consume months of time while the physical danger remains unchanged. The residents inside these 1300 buildings pay rent to landlords who cannot afford to make the buildings safe without government intervention.

The true measure of the Grenfell Tower Inquiry Phase 2 report lies in the physical changes to the built environment. The statistics from 2024 and 2025 confirm that the government failed to accelerate the remediation of social housing. Over two thousand six hundred public sector buildings lagged in the remediation data throughout 2024. By the end of 2025 the total number of identified defective buildings actually increased. The data proves that the Westminster government continues to discover lethal defects faster than the construction industry can remove them. The construction sector operates in the absence of the workforce required to fix thousands of high rise buildings simultaneously. The government data documents a permanent backlog of unsafe social housing.

The Legislative Void Following the Phase 2 Report

The Grenfell Tower Inquiry published its Phase 2 report on September 4 2024. The document contained 58 explicit recommendations designed to overhaul the construction industry and government oversight. The Westminster government published its formal response on February 26 2025. Officials accepted 49 recommendations in full and accepted the remaining nine in principle. Even with this broad acceptance the transition from published recommendations to enforceable law remains incomplete as of late 2025. The delay leaves dozens of directives awaiting statutory authority.

20. What panel did the government establish in April 2025?

The government established the Fire Engineers Advisory Panel in April 2025.

The Single Construction Regulator

The primary recommendation from the Phase 2 report calls for a single construction regulator. The Inquiry found that fragmented regulatory arrangements allowed severe safety failures to go unnoticed. Multiple agencies held partial responsibility for building control and product testing. The proposed single regulator would consolidate the regulation of construction products and oversee building control. The regulator would also manage the licensing of contractors working on higher risk buildings.

The government published a consultation document for the single construction regulator on December 17 2025. This document outlines the integration of functions currently split across the Ministry of Housing Communities and Local Government and the Home Office. The Building Safety Regulator currently operates under the Health and Safety Executive. The government plans to separate the Building Safety Regulator into a standalone entity to serve as the foundation for the new single regulator. Legislative action is required to formally transfer these powers and establish the new regulatory framework.

Redefining Higher Risk Buildings

The Phase 2 report identified serious flaws in the statutory definition of higher risk buildings. The existing Building Safety Act defines higher risk buildings based entirely on an arbitrary height threshold. The Inquiry stated that height alone does not determine the danger level of a building. The report recommended that the government urgently review this definition to include the nature of the building use and the presence of people.

The Building Safety Regulator completed an initial review of the higher risk building definition in February 2025. The government accepted the recommendation to revise the criteria has not yet passed legislation to amend the Building Safety Act. The absence of an updated legal definition leaves buildings housing populations outside the strictest regulatory oversight.

Construction Products Reform

The Inquiry exposed calculated dishonesty by product manufacturers regarding fire performance testing. Manufacturers manipulated test data and marketed unsuitable products for use in high rise buildings. To address this the Phase 2 report recommended that the new construction regulator take responsibility for certifying construction products. The report also demanded that manufacturers provide the full testing history of any product upon request.

The government published the Construction Products Reform Green Paper on February 26 2025. This document proposed institutional reforms to strengthen product testing and enhance enforcement powers. The government plans to publish a White Paper by spring 2026. Until Parliament passes a new Construction Products Act the industry relies on existing regulations that the Inquiry deemed insufficient.

Fire Engineering and Contractor Licensing

The Phase 2 report highlighted a severe absence of competence among professionals engaged in the construction industry. The Inquiry recommended that fire engineering become a regulated profession. The government established the Fire Engineers Advisory Panel in April 2025. The panel published an authoritative statement on December 17 2025 detailing the required skills and knowledge for competent fire engineers. Statutory regulation of the title and function of fire engineers requires new legislation.

The report also recommended a licensing scheme for principal contractors working on higher risk buildings. The Inquiry stated that a director or senior manager must provide a personal undertaking confirming that all reasonable care was taken to ensure building safety upon completion. The government accepted this recommendation has not yet introduced the statutory instruments required to enforce mandatory licensing.

Public Records and the Duty of Candour

The Inquiry criticized the government for failing to implement recommendations from previous investigations including the Lakanal House fire in 2009. The Phase 2 report recommended a legal requirement for the government to maintain a publicly accessible record of recommendations made by select committees and public inquiries. The government must describe the steps taken in response to each recommendation and report annually to Parliament.

The government also proposed a legal duty of candour for public authorities. This proposed legislation aims to compel public authorities to disclose the truth during major incidents. The government announced plans for this legislation in February 2025 the bill remains in the drafting phase.

Status of Phase 2 Recommendations

The following chart details the distribution and acceptance status of the 58 recommendations made by the Grenfell Tower Inquiry Phase 2 report.

The data shows that the Westminster government holds the primary responsibility for enacting the reforms demanded by the Inquiry. The nine recommendations accepted in principle require extensive consultation and legislative drafting before they become enforceable law. The delay in passing the Construction Products Reform Act and the updated Building Safety Act leaves the construction industry operating under the same fragmented regulatory system that the Phase 2 report condemned.
