Grenfell Tower Inquiry Phase 1 Report
On 14 June 2017, a fire broke out in Grenfell Tower, a block of flats in North Kensington, London. The fire started shortly before 1 am and engulfed the building within 15 minutes. 72 people were eventually confirmed dead.
The Inquiry has been led by retired high court judge Sir Martin Moore-Bick and is in two phases:
- The first phase looked into the development of the fire itself and the chain of events that unfolded before it was finally extinguished.
- The second phase will consider how the building came to be so seriously exposed to the risk of a disastrous fire.
Grenfell Tower Inquiry: Phase 1 Report. Report of the Public Inquiry into the fire at Grenfell Tower on 14 June 2017 was formally published on 30 October 2019. However, it was issued to the bereaved, survivors and residents on 28 October 2019. Recipients were asked to sign a non-disclosure agreement, but despite this, the contents of the report were leaked.
A post on the Inquiry website said: “The Chairman and the whole Inquiry team are very disappointed that someone has seen fit to disregard the confidential nature of the report during the embargo period. It is equally disappointing that media elected to publish what they would have been aware was subject to strict obligations of confidence.”
Although phase 1 of the Inquiry was not intended to consider the building itself, the report set out compelling evidence that the external walls of the building failed to comply with Requirement B4(1) of Schedule 1 to the Building Regulations. It suggests that: “The principal reason why the flames spread so rapidly up, down and around the building was the presence of the aluminium composite material (ACM) rainscreen panels with polyethylene cores, which acted as a source of fuel.”
Fire compartments then failed because:
- The intensity of the heat was such that the glass in the windows failed, allowing the fire to penetrate flats.
- Extractor fan units in kitchens had a tendency to deform and become dislodged, providing a point of entry.
- A number of key fire protection measures failed. Although some fire doors held back the smoke, others did not. Some were left open and failed to close because they did not have effective self-closing devices, and others were broken down by firefighters or wedged open with firefighting equipment.
- There had been no training in the dangers associated with combustible cladding.
- Incident commanders had received no training in how to recognise the need for an evacuation or how to organise one.
- Once it was clear the compartmentation had failed, a decision should have been taken to evacuate the tower between 01.30 and 01.50. However, the best part of an hour was lost before the “stay put” advice was revoked.
The report makes a wide range of recommendations, including recommendations in relation to:
- The evacuation of high-rise residential buildings.
- The information made available to fire and rescue services about the construction of buildings.
- The availability of plans of high-rise residential buildings to local fire and rescue services.
- The inspection and testing of lifts designed for use by firefighters.
- The inspection of fire doors and self-closing devices.
- The provision of fire safety information to residents of high-rise residential buildings.
- Command and control and the handling of emergency calls.
- Internal signage.
- Co-operation between emergency services.
In response to the report, General Secretary of the Fire Brigades Union, Matt Wrack, said: "The truth is that the fire spread the way it did because it was wrapped in flammable cladding. The firefighters turned up after that had happened, after the building had already been turned, in reality, into a death trap… Firefighters' actions on the night, which were remarkable in the circumstances, are now being scrutinised. Nobody is trying to avoid scrutiny, but we think that the ordering of the inquiry is completely back to front."
The Construction Leadership Council (CLC) said: "The CLC believes that as an industry, we must collectively play our part in eliminating this risk on both new and existing buildings. Collectively, we must support all actions that are being taken to reform the industry ahead of the completion of the 2nd phase of the enquiry (sic). The CLC fully supports the work of the MHCLG and industry bodies in taking forward the agenda set by Dame Judith Hackitt, to improve standards of competence, improve the system of building regulation and to ensure the safety of construction products, and are ready to play our role in the necessary reform of the industry’s approach to fire and wider building safety."

Prime Minister Boris Johnson said: “Today, the whole country, the whole world, is finally hearing the truth about what happened at Grenfell Tower on 14 June 2017. For the survivors, the bereaved, and the local community, this report will prove particularly harrowing. Yet I hope it strengthens their faith in the inquiry’s desire to determine the facts of the fire – and in this government’s commitment to airing those facts in public, no matter how difficult they may be, and acting on them.”
