Fire safety law for residential blocks has changed more in the last four years than in the previous two decades. The Building Safety Act 2022, the Fire Safety Act 2021, and updated guidance under the Regulatory Reform (Fire Safety) Order 2005 have together created a significantly more demanding compliance environment — with criminal sanctions for responsible persons who fail to meet it. For RMC and RTM directors managing blocks of any size in 2026, understanding exactly what is required, what a competent assessment covers, and what the Building Safety Regulator now expects is not optional.
This guide covers the legal basis for fire risk assessments in residential blocks, who the responsible person is and what that means in practice, how requirements differ by building height, what a compliant assessment must cover, when it must be reviewed, how to commission a competent assessor, and what the most common deficiencies look like when Fire and Rescue Services inspect. It applies to all residential blocks in England — from two-storey conversions to high-rises — with specific sections covering the enhanced obligations for higher-risk buildings above 18 metres.

The Legal Basis: Three Layers of Legislation
Fire safety in residential blocks sits across three interlocking pieces of legislation, each adding obligations on top of the last. Understanding which layer applies — and when — is the first step for any responsible person.
The Regulatory Reform (Fire Safety) Order 2005 is the foundational requirement. It applies to the common parts of all multi-occupied residential buildings — corridors, stairwells, lobbies, bin stores, plant rooms, and any other shared area. It requires the responsible person to carry out a suitable and sufficient fire risk assessment, implement appropriate fire safety measures, and review the assessment regularly.
The Fire Safety Act 2021 clarified, following the Grenfell Tower inquiry, that the RRO applies to the structure, external walls (including cladding and balconies), and flat entrance doors of multi-occupied residential buildings. These were previously contested areas. The Act removed the ambiguity: they are now unambiguously in scope and must be assessed.
The Building Safety Act 2022 created a distinct, more demanding regime for higher-risk buildings — those of 18 metres or more in height (or 7 or more storeys) with at least two residential units. Higher-risk buildings must register with the Building Safety Regulator, appoint a principal accountable person, maintain a safety case, and operate a residents' engagement strategy. The Act also created the Building Safety Regulator within the Health and Safety Executive.
Since the Fire Safety Act 2021 came into force, flat entrance doors in multi-occupied residential buildings are within scope of the RRO. This means the responsible person must include them in the fire risk assessment and take action on any deficiencies identified. In practice, this has required many blocks to assess and, in some cases, upgrade or replace flat front doors — a significant cost that falls within the scope of the building's fire safety obligations, not individual leaseholders' responsibility.
Who Is the Responsible Person?
The Regulatory Reform (Fire Safety) Order 2005 places duties on the "responsible person" — defined as the person who has control of the premises or who has an obligation by virtue of a contract or tenancy to maintain or manage them. In a residential block, identifying the responsible person is usually straightforward, but the position can be layered.
| Building Structure | Responsible Person | Notes |
|---|---|---|
| Freehold owned by RMC | RMC — Primary | The RMC directors are responsible. They will typically delegate operational fire safety management to a managing agent, but the duty remains with the RMC. |
| RTM company has exercised Right to Manage | RTM Company — Primary | Management functions — including fire safety — transfer to the RTM company. The RTM directors are responsible persons for RRO purposes. |
| Freeholder retains management | Freeholder — Primary | The freeholder is responsible. Where a managing agent is appointed, the agent acts on the freeholder's behalf but does not become the responsible person. |
| Multiple dutyholders (e.g. freeholder and head lessee) | Shared duty | Where two or more persons share control of premises, each is responsible for the parts they control. They must cooperate and coordinate fire safety measures. |
| Managing agent appointed | Agent — Delegated | The managing agent discharges fire safety obligations on behalf of the responsible person but does not bear primary RRO liability. The agent's contract should specify exactly what fire safety responsibilities are delegated. |
The RRO imposes duties on the responsible person — which in the case of an RMC or RTM company means the company itself and, potentially, its directors personally where the failure involves their individual conduct. Where a prosecution follows a serious fire safety failure, directors of management companies have faced personal criminal charges alongside the company. This is not a theoretical risk: prosecutions of block management companies and their officers have increased since the Building Safety Act came into force.
Requirements by Building Height and Risk
The fire safety regime in England is now explicitly tiered by building height. Your obligations depend on which category your block falls into.
Low-rise residential blocks
RRO 2005 applies to common parts. Written FRA required and must be kept under review. From October 2023, the FRA must be recorded in writing regardless of the number of employees — the previous exemption for small organisations no longer applies to residential buildings. No Building Safety Act registration required.
Medium-rise residential blocks
All RRO obligations apply. The Fire Safety (England) Regulations 2022 — in force from January 2023 — introduce additional specific requirements:
- Monthly checks of lifts, evacuation lifts, and firefighting equipment
- Quarterly checks of all fire doors in common parts, including self-closing mechanisms and seals
- Annual checks of all flat entrance doors (fire door condition and self-closing)
- Provision of building information to Fire and Rescue Services on request
- Display of fire safety instructions in the building
Higher-risk buildings (HRBs) — Building Safety Act 2022
All RRO obligations plus the Fire Safety (England) Regulations 2022 requirements above, plus the full Building Safety Act regime:
- Mandatory registration with the Building Safety Regulator (BSR) — failure to register is a criminal offence
- Principal Accountable Person (PAP) must be identified and take responsibility for the safety case
- Safety case report must be prepared, maintained, and submitted to the BSR on request
- Residents' engagement strategy must be in place — residents must be consulted on fire and structural safety matters
- Mandatory occurrence reporting — prescribed fire and structural safety occurrences must be reported to the BSR
- Golden thread of information — a digital record of all building safety information must be maintained
What a Fire Risk Assessment Must Cover
A "suitable and sufficient" fire risk assessment under the RRO is not a form-filling exercise or a tick-box checklist. The responsible person must demonstrate that fire hazards have been identified, the people at risk have been considered, and adequate protective measures are in place. For residential blocks, this means examining the common parts in detail — and since 2021, the structure, external walls, and flat entrance doors as well.
| Area / Element | What the Assessor Must Evaluate |
|---|---|
| Means of escape | Travel distances, number and width of escape routes, exit signs, emergency lighting, stairwell fire protection, lobby separation, refuges for disabled persons. Assessment of "stay put" vs. simultaneous evacuation strategy for the building. |
| Fire detection and warning | Communal fire alarm system — type, coverage, testing regime, link to individual flat detection. Smoke and heat detectors in common parts. Fire alarm control panel location and accessibility for firefighters. |
| Fire doors — common parts | Condition and rating of all fire doors in corridors and stairwells. Self-closing devices functional. Intumescent strips and smoke seals present and intact. Door gaps within tolerance. No wedges or hold-open devices unless compliant (electromagnetic hold-open on fire alarm release). |
| Flat entrance doors (post-2021) | Condition of every flat front door in the building. Fire resistance rating. Self-closing mechanism. Seals. Any visible damage or modifications that reduce fire resistance. Particularly important in older blocks where doors may pre-date modern fire door standards. |
| External walls and cladding | External wall system composition and fire performance. Identification of any ACM or high-pressure laminate cladding. Cavity barriers. Spandrel panels. This requires specialist knowledge — a general FRA assessor may not be qualified to assess cladding systems; a separate external wall assessment (EWS1 form) may be required. |
| Firefighting facilities | Dry or wet risers, hose reels, fire extinguishers in communal areas (type, location, servicing). Sprinkler systems where present. Firefighter access routes and control panels. |
| Arson risk and housekeeping | Storage of combustible materials in common parts. Mobility scooters and e-bikes/e-scooters — their lithium batteries present specific risks and the FRA must assess whether current storage and charging arrangements are acceptable. |
| Structural fire protection | Compartmentation — integrity of fire breaks between flats and common parts. Any penetrations (e.g. pipe runs, cable routes) through fire-rated walls or floors must be firestopped. Ceiling void fire protection where relevant. |
| Vulnerable occupants | Personal Emergency Evacuation Plans (PEEPs) for residents who cannot self-evacuate. Identification of residents with mobility, sensory, or cognitive impairments. Refuges and their accessibility. |
The National Fire Chiefs Council has specifically highlighted lithium battery fires as a fast-growing risk in residential buildings. Fires involving e-bikes, e-scooters, and mobility scooters stored and charged in common areas are disproportionately severe and fast-spreading. A 2026-standard FRA must specifically address how and where these are charged and stored. If your building currently allows unrestricted charging in corridors or bin stores, the FRA will likely flag this as a significant risk requiring immediate action.
When the FRA Must Be Reviewed
The RRO requires the responsible person to review the fire risk assessment regularly and whenever there is reason to believe it is no longer valid. There is no fixed statutory review interval for most buildings — the requirement is risk-based, not calendar-based. That said, best practice for residential blocks is an annual review of the existing assessment and a full physical reassessment every three to five years.
Beyond the routine review cycle, the following events should trigger an immediate reassessment:
For buildings within the Building Safety Act regime, the safety case must be kept up to date and the BSR can require it to be reviewed or updated at any time. The PAP must also report prescribed occurrences to the BSR promptly. This is a continuous compliance obligation, not a periodic one — the safety case is a live document, not a report filed once and forgotten.
How to Commission a Competent Assessor
The RRO requires that the fire risk assessment be carried out by a competent person. Following the Building Safety Act, competence requirements have been tightened and the government has moved toward expecting third-party certification for assessors working on higher-risk and complex buildings. Here is what to look for when appointing an assessor for a residential block.
-
1Third-party certification scheme membership. Look for membership of a UKAS-accredited certification scheme — the main ones are BAFE SP205 (Life Safety Fire Risk Assessment), Institute of Fire Engineers (IFE), the Institute of Fire Safety Managers (IFSM), or the Fire Risk Assessment Competency Council (FRACC) register. For higher-risk buildings, third-party certification is now effectively the expected standard.
-
2Experience with residential blocks specifically. Fire risk assessment for a residential block is materially different from commercial premises assessment. The assessor must understand compartmentation in residential layouts, flat entrance door standards, stay-put policies, evacuation strategies for mixed-occupancy buildings, and the specific requirements of the Fire Safety (England) Regulations 2022. Ask for examples of similar buildings assessed.
-
3Knowledge of the building's height tier. For medium-rise and higher-risk buildings, the assessor must understand the specific additional requirements — fire door inspection frequencies, BSR registration obligations, safety case concepts. A generalist assessor comfortable with low-rise blocks may not be qualified for an 18-metre building.
-
4Clear scope and written report format. Before commissioning, confirm exactly what the assessment will cover — including flat entrance doors, external walls (or whether a separate specialist assessment is required), and communal fire doors. The report should be structured, action-specific, and prioritised by risk level. A report that lists observations without prioritising them or specifying remedial actions is not fit for purpose.
-
5Professional indemnity insurance. Confirm the assessor holds professional indemnity insurance with adequate coverage for the scale and value of the building. This is standard for any qualified assessor.
-
6Independence from remedial contractors. The assessor should have no financial interest in the remedial works their assessment recommends. Arrangements where the assessor also supplies or manages the remediation create an obvious conflict of interest and may undermine the independence of the assessment.
Common Deficiencies Found on Inspection
The following are the most frequently identified failures when Fire and Rescue Services inspect residential blocks — and when managing agents or new RMC/RTM directors audit buildings they have recently taken over. None are unusual. All are preventable.
-
Flat entrance doors that fail to self-close or have damaged seals
In many older blocks, flat front doors have been modified, damaged, or have simply degraded to the point where they no longer provide meaningful fire separation. A door that does not fully close, has gaps around the frame, or has missing intumescent strips is not providing the compartmentation the building's fire strategy depends on. Since 2021, the responsible person must assess and act on these — not treat them as the leaseholder's problem.
-
Fire doors in common parts wedged open or held open by non-compliant devices
Propped-open fire doors in corridors and stairwells are one of the most commonly cited deficiencies. The door must either be held open by an electromagnetically activated hold-open device that releases on fire alarm activation, or it must be kept closed. Wedges, door stops, and tied-back closers are not compliant — regardless of how long the practice has been tolerated.
-
Combustible materials stored in escape routes
Bicycles, furniture, boxes, mobility scooters, and general clutter stored in corridors and stairwells represent both a fire load and an obstruction to escape. The responsible person must enforce a clear corridors policy and take action when residents breach it — not merely issue reminder notices that are ignored.
-
Inadequate or out-of-date emergency lighting
Emergency lighting in escape routes must be tested monthly (brief duration) and annually (full three-hour duration for maintained systems). Many blocks have emergency lighting that has never been properly tested, has failed bulbs, or has batteries that no longer hold charge. This is a direct risk to the safety of escape in the event of a fire occurring when mains power fails.
-
Inadequate compartmentation — unsealed penetrations
Every hole through a fire-rated wall or floor — pipe runs, cable routes, ventilation ducts — must be firestopped. In older blocks, decades of maintenance and refurbishment work have often created multiple unsealed penetrations that compromise the compartmentation the building relies on to contain fire. Identifying these requires intrusive investigation and is frequently overlooked in superficial assessments.
-
FRA not reviewed after building works or changes
The responsible person commissions an FRA and files it — then carries out a communal area refurbishment, installs new fire doors, or changes the building's alarm system without revisiting the assessment. The FRA becomes out of date and no longer reflects the actual risk profile of the building. The requirement to review after material changes is not optional and is one of the first things the Fire Service checks on inspection.
-
No documented evacuation strategy or out-of-date PEEPs
Many residential blocks operate an implicit "stay put" policy — but have no documented evacuation strategy, no signage communicating the strategy to residents, and no Personal Emergency Evacuation Plans for residents who cannot self-evacuate. Post-Grenfell, this is an area of active enforcement focus. The strategy must be documented, communicated to residents, and reviewed whenever the building or its occupants change materially.
Penalties for Non-Compliance
Fire safety non-compliance is a criminal matter. Unlike service charge disputes or planning breaches — which are civil and carry financial consequences — failures under the RRO can result in prosecution, unlimited fines, and imprisonment.
The Building Safety Act 2022 adds further criminal sanctions specific to higher-risk buildings — including failure to register with the BSR, failure to comply with BSR notices, and providing false information. These carry separate penalties of up to two years' custody on conviction.
Fire and Rescue Services were given enhanced inspection powers and have increased audit activity on residential blocks since the Building Safety Act came into force. The Building Safety Regulator itself has begun proactive inspections of higher-risk buildings. The era of fire safety compliance being largely self-regulated has ended. RMC and RTM directors should assume their building may be inspected and ensure it can withstand scrutiny.
Fire Safety Compliance Is Part of How We Manage Every Block
Most fire safety failures in residential blocks are not the result of negligence — they are the result of managing agents who do not have systems to track obligations, commission reviews, or follow up on remedial actions. We treat fire safety as a core operational function, not a compliance box to tick annually.
- FRA commissioning and oversight. We appoint third-party certified assessors for every block we manage, brief them on the building's history and any recent changes, and review the report before presenting it to directors.
- Action tracking. Every FRA action item is logged in our compliance system with a priority rating, a responsible party, and a target completion date. Directors receive status updates at each management meeting.
- Fire door inspection programme. We manage the quarterly common-parts fire door checks and annual flat entrance door checks required under the Fire Safety (England) Regulations 2022 — including contractor appointment, access coordination, and reporting.
- Building Safety Act readiness. For higher-risk buildings, we manage BSR registration, support safety case preparation, and operate the residents' engagement strategy required under the Act.
- Compliance gap analysis on takeover. When we take over a building, we conduct a full fire safety compliance review in the first 30 days — identifying any FRA gaps, overdue actions, and documentation deficiencies before they become enforcement issues.
Frequently Asked Questions
Fire Safety in Blocks Is Not Self-Regulating Anymore
The combination of the Fire Safety Act 2021, the Fire Safety (England) Regulations 2022, and the Building Safety Act 2022 has created a materially more demanding compliance environment than existed five years ago. FRS inspections are increasing, BSR scrutiny of higher-risk buildings is active, and the consequences of getting it wrong are criminal. For RMC and RTM directors, the question is not whether to take this seriously — it is whether your current managing agent has the systems to manage it properly.
