Fire in an HMO is one of the most serious risks in the private rented sector. Multiple occupants sharing kitchen and living facilities, often across multiple floors, means that fire can spread quickly and escape routes can become blocked. The fire safety standards required for HMOs are significantly higher than for single-family dwellings — and enforcement by local authorities and fire and rescue services is rigorous.
The LACORS Housing Fire Safety guidance (2008) remains the primary practical reference for HMO fire safety. Compliance with LACORS provides a strong defence against enforcement action and is the benchmark used by most councils when assessing HMO licence applications.
The fire safety legal framework for HMOs
Two overlapping regimes apply — both must be satisfied:
- The Regulatory Reform (Fire Safety) Order 2005 applies to the communal areas of HMOs (hallways, stairwells, common rooms). The responsible person (the landlord) must carry out a fire risk assessment and implement appropriate measures
- The HMO Management Regulations (the Management of Houses in Multiple Occupation (England) Regulations 2006) impose specific duties on the landlord or manager of a licensed HMO — including fire detection, escape routes, and fire fighting equipment
- HMO licence conditions: most licences impose explicit fire safety conditions as mandatory requirements. Breach of a licence condition is a civil penalty offence
- Fire and rescue service enforcement: the local fire and rescue authority can carry out inspections and issue enforcement notices independently of the council's licensing function — enforcement by both bodies is possible
- For smaller HMOs (3–4 persons, no communal areas): the HHSRS fire hazard provisions and HMO licence conditions are the primary framework. The RRO 2005 applies to a lesser extent but the practical standards remain high
Fire risk assessment — who, what, and how often
A documented fire risk assessment is the starting point for all HMO fire safety compliance:
- A fire risk assessment is a systematic evaluation of: fire hazards (ignition sources, combustible materials), persons at risk (number and location of occupants), and the adequacy of existing fire safety measures
- Competent person: for larger HMOs (purpose-built or converted buildings with communal areas), instruct a qualified fire risk assessor. For smaller HMOs, a documented self-assessment using the LACORS guidance is often sufficient
- LACORS Housing Fire Safety guidance (2008): the definitive practical guide for HMO fire safety. Sets out appropriate fire detection, escape route protection, and fire resistance standards for different property types. Available on the Local Government Association website
- Review frequency: at least annually, and after any significant change (layout change, new tenants, building works). A new tenancy with a different number or type of occupants should trigger a review
- Written records: the fire risk assessment must be documented. Keep it accessible and provide it to the council or fire authority if requested. Failure to produce a written assessment is itself an enforcement trigger
Smoke alarms and CO detectors — minimum standards for HMOs
Battery-only alarms are insufficient for licensed HMOs — mains-powered interlinked systems are required:
- The Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 require at least one smoke alarm on every floor, tested at the start of each new tenancy. For HMOs, licence conditions typically require a more extensive interlinked system
- Mains-powered, interlinked alarms: for licensed HMOs, the LACORS guidance and most licence conditions require mains-powered, interlinked smoke alarms — so a fire in one room activates alarms throughout the property. Battery-only alarms do not meet this standard
- Heat alarms in kitchens: smoke alarms false-alarm from cooking. Install heat alarms (or combined heat-and-smoke detectors) on the kitchen ceiling — connected to the interlinked system
- Carbon monoxide alarms: required in any room with a fixed combustion appliance (gas boiler, log burner) and in any room used for sleeping if a flue passes through it. Tested at the start of each tenancy
- Monthly testing record: document monthly alarm tests. Faulty alarms must be replaced immediately. A failure to replace a known faulty alarm that subsequently leads to a fire incident creates serious liability
Fire doors, escape routes, and emergency lighting
Structural fire safety measures are mandatory under both the RRO 2005 and HMO licence conditions:
- FD30S fire doors: 30-minute fire-resistant doors with cold smoke seals are required for bedroom doors, kitchen doors, and doors opening onto communal escape routes. Fire doors must self-close and latch properly — inspect self-closer mechanisms quarterly
- Fire door integrity: a propped-open fire door provides no protection. Provide tenants with clear instructions that fire doors must not be propped open. Consider installing automatic door closers that hold doors open but close on alarm activation (acoustic release hold-open devices)
- Escape routes: all escape routes must be kept clear of stored items (no bicycles, boxes, or furniture in hallways and stairwells). The route must be usable by occupants without specialist knowledge and must lead to a place of safety outside
- Emergency lighting: for larger HMOs or converted buildings with communal areas, battery-backup emergency lighting over the escape route (stairwell, corridors, exit signs) is typically required by licence conditions. Test monthly and annually by a competent person
- Upper-floor escape: where upper-floor rooms have no secondary escape route, the LACORS guidance requires enhanced fire detection and fire-protected corridor construction. Consider fire escape windows (compliant with BS 8214) for bedrooms with no alternative escape
Fire safety compliance — practical steps for HMO landlords
Build these steps into your pre-tenancy and ongoing maintenance routine:
- Carry out a documented fire risk assessment before the first tenancy and review it annually. Use the LACORS guidance as your benchmark — it is the same document the council's housing officers use
- Install a mains-powered, interlinked smoke alarm system before applying for an HMO licence — councils often reject applications where the alarm system does not meet standards
- Install FD30S fire doors on all bedroom and kitchen doors. Check self-closer mechanisms and smoke seals at every annual inspection. Replace any door that fails to self-close
- Brief tenants on fire safety at the start of every tenancy: location of fire exits, what to do if the alarm sounds, prohibition on propping fire doors, prohibition on storage in escape routes. Provide a written fire safety information sheet
- Keep records: fire alarm test dates, fire door inspection dates, fire risk assessment review dates, extinguisher service records (where supplied). These records are your compliance evidence for the licensing authority, the fire and rescue service, and any future enforcement action
Frequently asked questions
Do I need a professional fire risk assessor for my small HMO?+
For a small HMO (3–4 persons, no communal areas beyond the entrance hallway and staircase), a thorough self-assessment using the LACORS Housing Fire Safety guidance is generally acceptable. For larger HMOs, converted buildings with communal areas, or properties where you are uncertain about fire resistance standards, a qualified fire risk assessor is strongly advisable. The cost of a professional assessment (typically £200–£500) is far less than the cost of enforcement action or — in the worst case — a fire.
My council has required FD30S fire doors in all my HMO bedrooms — is this correct?+
Yes — FD30S fire doors (30-minute fire-resistant doors with intumescent seals and cold smoke seals) on bedroom doors is a standard requirement for licensed HMOs under the LACORS guidance and most council licence conditions. This requirement protects occupants by containing a fire to the room of origin for at least 30 minutes, allowing time for escape. Older solid timber doors should be replaced with compliant fire doors — do not assume that a solid-looking door provides 30-minute fire resistance.
A tenant is propping fire doors open — what can I do?+
Address this immediately. Write to the tenant (or to all tenants if it is a shared property) reminding them that fire doors must not be propped open, that doing so is a breach of the tenancy agreement (include an HMO fire safety clause in your agreement), and that you will inspect compliance. Consider installing electromagnetic hold-open devices that keep fire doors open during normal use but release automatically when the fire alarm activates — this resolves the convenience issue that causes tenants to prop doors. Document the breach if the tenant continues to prop doors after a written warning.
How often should I test the fire alarm system in my HMO?+
The LACORS guidance and most HMO licence conditions require: a weekly test of one call point (rotating through all call points over time), an annual test and service of the whole system by a competent person, and documentation of all tests. Some councils require monthly rather than weekly testing — check your licence conditions. Provide tenants with instructions on how to test the alarm and ask them to report any faults immediately. Keep a log of all test dates and outcomes.
