What Is the Fire Safety Act 2021? One Missed Wall Check

An inspector from the fire and rescue authority asks for the fire risk assessment for a residential block, and then asks the question that decides the visit: where in that document is the external wall? The facilities manager reaches for the file, finds a generic assessment that covers the common parts, the bin store and the alarm, and discovers that the wall itself was never in scope. That gap is now the director's problem, because the Fire Safety Act 2021 closed it.

If you run residential blocks, the answer to "What Is the Fire Safety Act 2021?" is not academic. It is the reason your fire risk assessment has to name the structure, the external walls and the flat entrance doors, and the reason you may be asked to prove it on the day.

The Act put external walls and flat entrance doors beyond doubt

Sections 1 and 3 of the Fire Safety Act commenced on 16 May 2022. The Act amends article 6 of the Regulatory Reform (Fire Safety) Order 2005, usually called the Fire Safety Order, and it puts beyond doubt that structure, external walls and flat entrance doors fall within the scope of that Order in the case of multi-occupied residential buildings. The commencement factsheet on sections 1 and 3 sets out the position plainly.

Before the Act there was genuine ambiguity about whether external walls and flat entrance doors of a multi-occupied residential building should be included in the fire risk assessment required under the Fire Safety Order. The factsheet for lenders describes that ambiguity and how the Act resolved it. For a facilities manager, the practical effect is simple: the assessment you hold has to cover the wall and the front door of every flat, not just the corridors and the plant room.

The duty rests with the responsible person. Where a building contains two or more sets of domestic premises, that person must take account of structure, external walls and flat entrance doors in the fire risk assessment. Any building with two or more domestic premises and a shared common area, internal or external, falls within the Fire Safety Order. That covers most of the residential stock a UK portfolio holds, from a converted terrace in Leeds to a tower in Manchester.

What the inspector actually looks at on site

The visit is rarely a surprise inspection of the building fabric. It is a test of whether your paperwork matches the building in front of them. The inspector wants to see the current fire risk assessment, and then wants to see where the external wall and the flat entrance doors are addressed inside it. If the assessment was written before the Act and never updated, that is the finding.

On the wall itself, the assessor should have carried out a visual inspection where the fire risk assessment had not already been updated to include external walls. In many cases it will be manifestly obvious through a visual inspection that the risk to life from external fire spread is not such as to warrant a PAS 9980 assessment. That is particularly true in buildings with brick or masonry external walls, or low risk buildings which do not present any significant risk of fire spread. A competent assessor can record that judgement and move on.

The picture changes where there is a known or suspected risk from the form of construction, such as combustible materials used for cladding or external wall insulation. Then a more detailed fire risk appraisal of the external walls under PAS 9980 may be required, and a competent person should be appointed to carry it out. PAS 9980 provides the methodology for the fire risk appraisal of external wall construction and cladding in existing multi-occupied residential buildings. Where that appraisal, called a FRAEW, is conducted, it should give the responsible person recommendations on remedial action considered necessary, with a suitable time frame.

Flat entrance doors are the other half of the check. The assessor looks at the door between each flat and the common parts, because that is the door the Act brings into scope. A door that has been replaced by a leaseholder without certification, or one that no longer closes fully into its frame, is a finding that lands on the responsible person, not the resident.

Where the evidence usually lives, and what good looks like

Good evidence is not a single certificate. It is a chain that a stranger can follow without your help. The current fire risk assessment should state the building address, the date of the assessment, the name and competence of the assessor, and a section that deals explicitly with the external wall and the flat entrance doors. If a PAS 9980 appraisal was done, the FRAEW report sits alongside it, with its recommendations and time frames.

For high-rise residential buildings in England, there is a further layer. The Fire Safety (England) Regulations 2022 made it a legal requirement from 23 January 2023 for responsible persons of existing high-rise residential buildings in England to provide their local fire and rescue service with information about the design and materials of the building's external walls. Responsible persons must also inform their local fire and rescue service of any material changes made to external walls. If a remediation project changes the cladding, the file has to change with it.

Section 3 of the Act matters here. It makes clear that if a responsible person has followed the article 50 commencement guidance, they may then be able to use evidence of this compliance to demonstrate that they have met their obligations under the Fire Safety Order. If they have not complied with the guidance or the prioritisation tool, they may need to provide alternative evidence of how they have complied with this aspect of their Fire Safety Order obligations. The Fire Risk Assessment Prioritisation Tool has since closed, and the guidance was amended on 5 June 2026 to reflect that, so the evidence you hold now has to stand on its own.

One point that trips up portfolio managers: where the assessment has been carried out, for multi-occupied residential buildings of any height, the fire risk assessment does not need to be updated again other than after a review as required by article 9 of the Fire Safety Order. You are not chasing a fresh assessment every quarter. You are keeping the one you have current, and reviewing it when the building or its use changes.

What this costs you when the evidence is thin

The immediate cost is rarely a fine. It is the remediation bill that arrives without warning, because a FRAEW has recommended work with a time frame and the budget was set before the recommendation existed. It is the insurer asking for the external wall information before renewal, and the buyer's solicitor asking the same question during a disposal. The Fire Safety Act 2021 policy paper is clear that fire risk assessments are technical documents which cover a wide range of fire protection precautions, and that they cannot provide a binary output to inform lending decisions. That is precisely why lenders and buyers ask for the underlying evidence instead.

For a facilities manager with a thin team, the workable answer is a single building file per block, holding the current assessment, the wall appraisal if one exists, the door inspection records, and the information sent to the fire and rescue service. If you want to see how this plays out across a portfolio, the piece on how the Fire Safety Act 2021 reshapes multi-occupied building deals is worth ten minutes. So is the one on how the Act expands your liability in multi-occupied residential buildings.

Your 60-second self-check

• Could you produce the current fire risk assessment for every residential block today, and point to the section that covers the external wall?
• Could you show the flat entrance door inspection records for the last cycle, for every block, without asking a colleague to dig them out?
• For any high-rise residential building in England, could you show what was sent to the local fire and rescue service about the design and materials of the external walls, and any update after a material change?

If you want to walk into the next board or senior management meeting with answers rather than follow-ups, the free 5-minute Director's Risk Check gives you a control score for each building, the portfolio's breach exposure with official sources attached, and a board-ready briefing you can send to a colleague to complete. Five minutes now is a small price for not being the director who finds out on the day.

Herman's verdict

The fire risk assessment is not a document you file and forget. It is the record that proves you looked at the wall and the front door, and the only thing standing between a routine inspector visit and a remediation bill with your name on the covering note.
