HMO fire safety regulations require the landlord to carry out and record a fire risk assessment, provide a suitable fire detection and alarm system, keep escape routes clear and maintain fire doors, emergency lighting where needed and smoke and carbon monoxide alarms. Larger HMOs also need a licence from the council, which adds its own fire safety conditions.
This guide sets out what applies to a house in multiple occupation in England, where the rules come from, and what councils usually expect. It is written for landlords and managing agents. Our own HMO fire risk assessment service covers the practical side.
What counts as an HMO?
A house in multiple occupation is a property let to people who are not one household, who share facilities such as a kitchen or bathroom. For mandatory licensing in England, an HMO is generally a property occupied by five or more people forming two or more households. Councils can also bring smaller HMOs into licensing through additional or selective licensing schemes, so the licensing position depends on your street as well as your building. Always check with your local council.
Which laws apply to HMO fire safety?
| Rule | What it means for an HMO landlord |
|---|---|
| Regulatory Reform (Fire Safety) Order 2005 | Applies to the shared parts of an HMO. You must assess fire risk, record it and keep it under review. |
| Housing Act 2004 (HHSRS and licensing) | The council can assess fire hazards inside the whole property, including bedrooms, and attach licence conditions. |
| Smoke and Carbon Monoxide Alarm (England) Regulations 2015, as amended | Smoke alarms on each storey used as living accommodation, and carbon monoxide alarms in rooms with a fixed combustion appliance, with checks at the start of each tenancy. |
| Building Safety Act 2022, Section 156 | Since 1 October 2023 the responsible person must record the full fire risk assessment in all circumstances, including the assessor’s name and organisation. |
Where an HMO contains self-contained flats or is part of a larger converted building, other duties may also apply. If you are unsure which regime covers you, the risk assessment should say so.
Do HMOs need a fire risk assessment?
Yes. The shared parts of an HMO are not a private home, so the Fire Safety Order applies and the landlord, or whoever controls the premises, is the responsible person. The assessment should look at hazards, who is at risk (including people who are asleep), the escape routes, detection and warning, firefighting equipment, emergency lighting and the management arrangements. It must be recorded and kept up to date. Our fire risk assessment cost guide explains what a fair fee includes.
Fire alarm requirements in an HMO
Councils commonly refer to the LACORS housing fire safety guidance when setting standards for HMOs. In broad terms:
- A small, low-risk shared house may be expected to have interlinked, mains-powered smoke and heat alarms with battery back-up, usually described as a Grade D system.
- Larger or higher-risk HMOs, including those with more storeys or more complex layouts, are often expected to have a full fire alarm panel with detectors and sounders, usually described as a Grade A system, to a stated category such as LD2 or LD1.
- Where the property has a shared kitchen, heat detection is normally expected in that room rather than a smoke detector that would be triggered by cooking.
The right level is not a fixed number. It depends on size, layout, number of occupants and the council’s own standards, so use the assessment and your licence conditions as the reference point. Whatever the system, it needs regular testing and servicing, with the results logged.
Smoke alarm and carbon monoxide alarm rules
Under the Smoke and Carbon Monoxide Alarm (England) Regulations 2015, as amended, a private landlord must fit at least one smoke alarm on every storey of the property used as living accommodation. A carbon monoxide alarm must be fitted in any room used as living accommodation that contains a fixed combustion appliance, excluding gas cookers, and a landlord must make sure the alarms are working on the first day of each tenancy. If an alarm is reported faulty, it must be repaired or replaced. Councils can issue a civil penalty for breaches, so keep dated records of your checks. The government publishes an explanatory booklet for landlords.
Fire door requirements in an HMO
Escape routes in an HMO normally depend on fire doors to keep a fire out of the stairs and hall for long enough to leave. Typical expectations are:
- Doors to bedrooms and other rooms that open onto the escape route are fire-resisting and fitted with the correct frames, intumescent strips and smoke seals.
- Doors close fully and securely, using a properly fitted self-closing device where one is required.
- Gaps, hinges and glazing are in good order, with no damage or later alterations that weaken the door.
- Nothing is propped, wedged or tied open.
Many councils expect the doors to be 30-minute fire doors, and some require them to be fitted with smoke seals. Check your licence and the assessment.
Emergency lighting, escape routes and instructions
Escape routes should be clear, lit and easy to follow. In larger HMOs, emergency lighting may be needed in the stairs and halls, with periodic testing recorded. Residents should be told what to do if they hear the alarm, where the escape routes are and what to do if the way out is blocked. Fire action notices are normally displayed in shared areas.
Licensing conditions and penalties
An HMO licence usually sets conditions that the landlord must meet, which commonly include fire detection, fire doors, emergency lighting, maintenance and keeping fire safety records. Operating a licensable HMO without a licence, or breaking licence conditions, can lead to civil penalties of up to £30,000 per offence or prosecution with an unlimited fine, depending on the offence and the council’s approach. Breaches of the Fire Safety Order can also lead to prosecution. Councils publish their own HMO standards, which should be read alongside this guide.
HMO fire safety checklist for landlords
- Check whether the property needs a licence and whether it is in an additional or selective licensing area.
- Commission a recorded, suitable and sufficient fire risk assessment and keep it under review.
- Install and maintain the alarm system your assessment and licence require, and test it regularly.
- Fit smoke and carbon monoxide alarms as the 2015 regulations require, and test them at the start of each tenancy.
- Inspect fire doors and keep escape routes clear.
- Keep dated records of every test, inspection and repair.
- Give residents clear fire safety information on arrival.

HMO fire safety: frequently asked questions
Do I need a fire risk assessment for my HMO?
Yes. The shared parts of an HMO are covered by the Fire Safety Order, so the landlord must carry out a suitable and sufficient fire risk assessment, record it and keep it under review.
What fire alarm does an HMO need?
It depends on the size, layout and your council’s standards. Small shared houses often need interlinked mains-powered alarms (Grade D). Larger or higher-risk HMOs are often expected to have a full fire alarm system (Grade A). Your assessment and licence will state which applies.
Do HMO bedrooms need fire doors?
Often yes, where the bedroom opens onto an escape route. Many councils expect 30-minute fire doors with smoke seals and self-closing devices. Check your licence conditions and your assessment.
Do I need a carbon monoxide alarm in an HMO?
You need one in any room used as living accommodation that has a fixed combustion appliance, excluding gas cookers. Smoke alarms are required on each storey used as living accommodation.
What happens if an HMO does not meet fire safety standards?
The council can serve notices, add or enforce licence conditions, issue civil penalties or prosecute. The fire and rescue service can also enforce the Fire Safety Order in the shared parts.
