11 metres, 18 metres and licensed HMOs, UK wide
High-Rise Residential and HMO Fire Safety
Residential fire safety duty now steps up at defined heights and a building that clears one threshold by a metre carries a materially different legal load from the one next door. AL23 Safety provides fire risk assessment, evacuation strategy and building safety support to landlords, managing agents, resident management companies and HMO operators across the UK.
Why it matters in high-rise residential and HMOs
The risks are real and so are the duties
This page deals with the height-banded fire duties and the houses in multiple occupation regime. Broader landlord and managing agent obligations sit on our health and safety in housing and property page and the Regulator of Social Housing consumer standards, Awaab's Law and the Decent Homes Standard sit on our social housing health and safety page. If you are a registered provider with tall blocks you will need all three and we run them as one programme rather than three unconnected pieces of work.
The reason the thresholds matter is that they are absolute. A building over 11 metres picks up fire door checking duties whether it is a converted mill or a new build. At 18 metres or seven storeys with two or more residential units it becomes a higher-risk building, with registration, an accountable person and a safety case report. Nobody is grandfathered. The Building Safety Regulator became a standalone body sponsored by MHCLG on 27 January 2026 and it paused new building assessment certificate applications on 9 July 2026 while it redesigns the process, having refused around two thirds of applications that year. The BSR was explicit that the underlying legal safety duties continue to apply throughout the pause. Nothing about the pause reduces what you owe your residents.
The main risks
Where the harm comes from
Compartmentation breaches
Service penetrations, riser shafts and post-handover data and access control installations quietly remove the fire separation the stay put strategy depends on.
Fire door failure
Missing or disconnected self-closing devices, damaged intumescent and smoke seals and doors wedged open during works are the most common defect found in occupied blocks.
External wall systems
Combustible insulation, cladding, balconies and window details can carry fire past compartment lines entirely and change the evacuation strategy on their own.
Lithium-ion charging
E-bikes and e-scooters charged in flats, corridors and bin stores produce fast, hot fires in exactly the places escape depends on.
Escape route obstruction
Buggies, bicycles, furniture and combustible storage in lobbies and stairs remove the width and the sterility the design assumed.
HMO alterations
DIY partitioning, cooking inside a bedsit on the escape route, overcrowding and blocked escape windows defeat the fire strategy from the inside.
The regulations that apply
Your legal framework, in plain terms
The Regulatory Reform (Fire Safety) Order 2005 governs the common parts, extended by the Fire Safety Act 2021 to the structure, external walls including cladding, balconies and windows and to flat entrance doors opening onto common parts. Section 156 of the Building Safety Act 2022, commenced on 1 October 2023, requires the fire risk assessment to be recorded in full regardless of building size, together with the arrangements, the responsible person's name and UK address and the identity of anyone engaged to carry out the assessment. Inside the dwelling the Housing Act 2004 applies, giving the local housing authority the Housing Health and Safety Rating System and the houses in multiple occupation licensing regimes. The Management of Houses in Multiple Occupation (England) Regulations 2006, SI 2006/372, impose duties directly on the manager whether or not the HMO is licensed. Building Safety Act 2022 Part 4 then sits on top for higher-risk buildings in occupation.
Fire Safety (England) Regulations 2022
Height-banded duties in force since 23 January 2023, set out in full below.
Building Safety Act 2022 Part 4
Registration, accountable person duties, safety case report and mandatory occurrence reporting at 18 metres or seven storeys with two or more residential units.
Fire Safety (Residential Evacuation Plans) (England) Regulations 2025
SI 2025/797, in force 6 April 2026, introducing person-centred fire risk assessments and emergency evacuation statements.
Housing Act 2004
Mandatory HMO licensing at five or more persons in two or more households, plus additional and selective licensing schemes set locally.
Management of HMO (England) Regulations 2006
Manager duties including means of escape kept free from obstruction and in good order.
Fire safety in high-rise residential and HMOs
Reading the height bands and knowing when stay put fails
Start with what the Fire Safety (England) Regulations 2022 actually require because the bands are frequently misread. Every building containing two or more sets of domestic premises, at any height, must give residents fire safety instructions appropriate to the evacuation strategy, covering how to report a fire and what to do if one occurs, plus information on the importance of fire doors. Above 11 metres the responsible person must check all fire doors in the common parts at least every three months and must use best endeavours to check every flat entrance door at least annually, including the self-closing devices, keeping records including of refused access. At 18 metres or seven storeys the duties step up again. You must provide the fire and rescue service with electronic building floor plans and a single-page block plan, install and maintain a secure information box holding hard copies and responsible person contact details, provide information on the design and materials of the external wall system including risk levels and mitigations and notify the service of material changes, carry out monthly checks of firefighting lifts, evacuation lifts and other key firefighting equipment with any fault that cannot be fixed in 24 hours reported to the fire and rescue service, record the results and make them available to residents and install wayfinding signage visible in low light or smoke identifying flat and floor numbers in stairwells. Our fire door surveys are structured around the three month and twelve month intervals so the record set matches the duty rather than approximating it.
Part 4 of the Building Safety Act 2022 applies to buildings of at least 18 metres or seven storeys with at least two residential units. The duties are registration with the Building Safety Regulator before occupation, identification of the accountable persons and the principal accountable person, assessment and management of the building safety risks of fire spread and structural failure, preparation of a safety case and submission of a safety case report, application for and compliance with a building assessment certificate when directed, mandatory occurrence reporting, maintenance of the golden thread of building information and a residents' engagement strategy with a complaints procedure. Residents carry their own duties under sections 95 and 96. One point causes constant confusion. Care homes and hospitals fall within Part 3 for design and construction but are excluded from the Part 4 in-occupation regime. The higher-risk building definition was reviewed and left unchanged, confirmed on 17 December 2025.
Stay put is not a policy you choose. It is a conclusion you draw. It holds only where each flat is a fire resisting compartment and fire will not spread beyond the flat of origin within the design period. Where compartmentation, the external wall system, fire doors or the smoke control system are known to be defective, the fire risk assessment must move the building to simultaneous evacuation. That change is not a line in a report. It requires a means of raising the alarm throughout the building, which means a common fire alarm system or, as a short-term interim measure only, a waking watch. Our waking watch and interim measures work is built around replacing that cost with a permanent alarm as quickly as the funding and the programme allow.
Changing to simultaneous evacuation above 11 metres now also triggers the Fire Safety (Residential Evacuation Plans) (England) Regulations 2025, SI 2025/797, in force since 6 April 2026. They apply to all high-rise residential buildings at 18 metres or seven storeys with two or more domestic units and to multi-residential buildings over 11 metres operating a simultaneous evacuation strategy. The responsible person must use reasonable efforts to identify relevant residents, meaning those for whom the building is their only or principal residence and who need assistance to evacuate because of a physical or cognitive impairment. You must offer each of them a person-centred fire risk assessment, record the agreed approach in a written residential emergency evacuation statement and give the resident a copy, share prescribed information with the fire and rescue authority only with the resident's explicit consent, install and maintain a secure information box if the authority asks for hard-copy sharing and prepare a building emergency evacuation plan reviewed annually or on change. The statements and the person-centred assessments are reviewed annually too. Note the statutory term is emergency evacuation statement. Residential PEEP is sector shorthand, not the language of the regulations. In practice this is a data, consent and resident engagement exercise as much as a fire safety one.
For shared housing and HMOs the benchmark used by councils and fire and rescue services remains the LACORS housing fire safety guidance of 2008, now maintained by the National Fire Chiefs Council. It is non-statutory. It gives risk-proportionate specifications for detection grade and category to BS 5839-6, fire doors, protected routes and escape windows and it bridges Housing Act enforcement inside the dwelling and Fire Safety Order enforcement in the common parts. Be honest about its age. LACORS predates the Fire Safety Act 2021, the Fire Safety (England) Regulations 2022, section 156 and the 2026 rating system and no replacement has been announced. We use it as the starting benchmark and say where a later duty overtakes it. Alongside it, the new Housing Health and Safety Rating System comes into force on 23 June 2026 under SI 2026/571, cutting 29 hazards to 21 with revised scoring, new baseline indicators and new statutory operating and enforcement guidance. Fire remains a hazard in its own right, a category 1 hazard creates a duty to act rather than a power and from 22 June 2026 councils can issue a £7,000 civil penalty for failing to fix serious hazards.
Lithium-ion charging deserves a paragraph of its own. Department for Transport guidance published on 1 February 2024, covering England, Scotland and Wales, sets the practical controls: locate charging and storage so a fire cannot block escape routes, provide automatic ventilation linked to fire detection, keep 45 centimetres of separation between charging battery packs, provide secure battery lockers to discourage charging inside flats, prohibit visibly damaged batteries and in workplaces consider prohibiting on-site charging altogether. It points to London Fire Brigade guidance note GN103 for detail. It is also explicit that introducing a new fire hazard requires the fire risk assessment to be reviewed by a competent person, not signed off by the premises manager alone.
One honest limitation. Article 9A of the Fire Safety Order, inserted by section 156(4) of the Building Safety Act 2022 to govern the competence of anyone appointed to assist with a fire risk assessment, has not been commenced. Competence remains a practical expectation backed by BS 8674:2025 and by third-party schemes rather than a commenced statutory test. We also do not publish figures for HMO civil penalties or rent repayment orders because the commonly quoted numbers predate amendments made by the Renters' Rights Act and we have not been able to verify current values against a primary source.
How we help
Built around your operation
We work portfolio-wide rather than building by building so the same threshold question is answered once and applied consistently across the stock.
- Recorded fire risk assessment to section 156, with the external wall element addressed rather than deferred.
- Height banding review across the portfolio, establishing which buildings sit above 11 metres, which meet the higher-risk test and what each one therefore owes.
- Fire door inspection programmes on the quarterly communal and annual flat entrance cycles, with refused access logged.
- Compartmentation surveys and defect scheduling prioritised by the escape routes the evacuation strategy relies on.
- Evacuation strategy review, including the evidence base for retaining or leaving a stay put strategy.
- Residential evacuation plan implementation, covering identification of relevant residents, person-centred assessments, emergency evacuation statements and the building emergency evacuation plan.
- Safety case report development, golden thread structuring and building assessment certificate preparation for higher-risk buildings.
- HMO licensing support, Management of HMO Regulations 2006 compliance and LACORS benchmarked assessment for shared houses and bedsits.
- Lithium-ion charging policy, storage location design and resident communication that management can actually enforce.

Contact usAbove 11 metres you must check all fire doors in the common parts at least every three months and use best endeavours to check every flat entrance door at least annually, including self-closing devices, keeping records including of refused access. If the building also operates a simultaneous evacuation strategy, the Fire Safety (Residential Evacuation Plans) (England) Regulations 2025 have applied since 6 April 2026 and you must identify relevant residents and offer person-centred fire risk assessments.
You do not choose. The strategy follows the physical condition of the building. Where compartmentation, fire doors, the external wall system or smoke control are defective the assessment has to move the building to simultaneous evacuation and that requires a means of alerting everyone. A waking watch is a short-term bridge only and should be replaced by a common fire alarm as soon as reasonably practicable.
Not the same but overlapping. The Fire Safety Order applies to the common parts, the Housing Act 2004 and the Management of HMO Regulations 2006 apply inside and the practical benchmark for detection, doors and escape routes in converted housing is still the 2008 LACORS guidance. Mandatory licensing bites at five or more persons in two or more households and many councils operate additional or selective schemes that catch smaller properties.
The drivers are the number of buildings, their height, the number of flats, whether an external wall appraisal is needed and how much reliable record information already exists. A single recorded fire risk assessment on a low-rise block is a short job. A safety case report with a compartmentation survey and a residential evacuation plan rollout across a tall block runs over several months. Pay as you go is £95 per hour or £695 per day plus VAT. Call us and we will price it against your actual stock.
