North Kensington, London · 14 June 2017
At 00:54 on 14 June 2017, a fire started in a fourth-floor flat at Grenfell Tower caused by an electrical fault in a fridge-freezer. It should have been contained to that flat. It was not.
Within minutes the fire reached the building's exterior via highly combustible aluminium composite material (ACM) cladding installed during a 2016 refurbishment. It reached the roof in under 30 minutes. By 2am it had engulfed the entire building. Seventy-two people died — Britain's deadliest residential fire since World War II.
The Grenfell Tower Inquiry's final report, published 4 September 2024, concluded that the fire was "the culmination of decades of failure by central government and other bodies in positions of responsibility in the construction industry."[1] The government accepted the inquiry's findings and all 58 recommendations in February 2025.[2]
The cladding killed 72 people. But it did not arrive on the building unannounced.
The inquiry documented a decade of accumulated warnings about the building's fire safety that were ignored, dismissed, or suppressed by the Kensington and Chelsea Tenant Management Organisation (KCTMO).
The inquiry found a significant backlog of fire safety issues that were ignored, an emergency plan that was outdated and incomplete, and that the architect, principal contractor, and cladding subcontractor all assumed others were responsible for fire safety — so it was not taken seriously by anyone.[3]
The inquiry found no adequate system at KCTMO for ensuring that defects identified in fire risk assessments were remedied effectively — and chronic, systemic failings in the routine inspection and maintenance of fire doors.[1]
72 people dead. A seven-year public inquiry. Criminal investigations ongoing by the Metropolitan Police, who by May 2024 had 180 officers and staff investigating potential offences.[4] The government accepted all 58 inquiry recommendations in February 2025.[2]
The Building Safety Act 2022 — the most significant reform of building safety regulation in a generation — flows directly from Grenfell. The Golden Thread of building information, mandatory for higher-risk buildings, is a legislative response to exactly the documentation failures the inquiry identified.
The reputational, financial, and criminal consequences for the organisations involved continue to unfold. No prosecutions had concluded at the time of writing.
72 people. Their names are recorded on the memorial at the base of the tower, which remains standing, wrapped in white cladding, in North Kensington.
Of the 37 disabled residents living in Grenfell Tower at the time of the fire, 15 lost their lives — 41% of the building's disabled population.[4]
Families followed the 'stay put' advice given by 999 operators. That advice was based on the assumption that the building's fire compartmentation was intact. It was not. People who did as they were told died because of it.
The survivors and bereaved have waited seven years for a final report that named what happened and who was responsible. Criminal proceedings, if they come, remain ahead of them.
Grenfell is rightly understood as a cladding disaster. CleanReports does not detect combustible cladding, and we will not claim otherwise. The systemic regulatory and governmental failures documented in the inquiry — dishonest manufacturers, inadequate building regulations, decades of government inaction — are outside the scope of any communal area compliance platform.
What CleanReports addresses is the occupation-phase evidence gap that the inquiry also documented: the complete absence of a continuous, independent record of building condition observed by the people physically present in the building every week.
The Golden Thread, started from day one. The Building Safety Act 2022 requires a Golden Thread of building information for higher-risk buildings — a continuous, structured record of the building's condition throughout its occupied life. Every CleanReports inspection visit contributes to that thread. Fire door condition, self-closer function, communal escape route integrity — logged, timestamped, and stored in an immutable audit trail from the first visit onwards.
Fire doors observed on every visit. The inquiry found chronic, systemic failures in the routine inspection and maintenance of fire doors at Grenfell — doors that from 2011 were not meeting fire resistance standards, doors that the London Fire Brigade had issued an enforcement notice about in 2015. A cleaning operative attends the communal areas of a building more frequently than almost any other contractor. CleanReports turns every one of those visits into a structured fire door observation — condition noted, self-closer checked, any defect flagged and routed to the responsible person on the date it is observed.
An immutable notification record. KCTMO's central defence — that it was unaware of the scale of communal defects — was possible because no independent, timestamped record existed to contradict it. CleanReports creates exactly that record. Every defect observation generates an automatic notification to the responsible person, creating a documented chain that shows when they were informed and what, if anything, they did in response.
Contractor verification. The inquiry found that responsibility for fire safety fell between organisations because no one knew who was accountable. CleanReports' access pyramid logs every operative, contractor, and managing agent interaction against the building record — a verified chain of who attended, when, and what they found.
Implementing the lessons learned. The inquiry's 58 recommendations were accepted by government in February 2025. For managing agents and landlords, the question is no longer whether the lessons are known — it is whether their buildings have the systems in place to demonstrate compliance with them. CleanReports provides the occupation-phase evidence layer that regulators, the Building Safety Regulator, and future inquiries will expect to see: a continuous, independent record proving that the building was being monitored, that defects were being captured, and that responsible persons were being notified.
The case for CleanReports at Grenfell is not that it would have saved 72 lives. The case is that the building had a decade of observable warning signs — fire doors that weren't closing, defect notices that weren't resolved, a fire strategy that was never approved — and none of it was captured in a continuous, independent, timestamped record. The people walking through those corridors every week had no mechanism to make their observations permanent, dated, and legally standing. CleanReports is that mechanism. Not a promise of safety. Proof of process.
