Fire Risk Assessment for HMOs: A Landlord's Guide to Staying Legal

If you let a house in multiple occupation, a fire risk assessment HMO landlords are legally required to have is not a nice-to-have — it is a duty under the Regulatory Reform (Fire Safety) Order 2005 and, for many HMOs, under the Housing Act 2004 licensing regime as well. An HMO packs several unrelated households into one building with shared escape routes, and that shared staircase is exactly where fire becomes lethal. The responsible person is usually the landlord or managing agent, who must assess the risk, maintain fire detection, keep escape routes clear and plan for evacuation. Because HMOs are high-risk, the assessment falls into the Enhanced tier, from £849 plus VAT. Get it wrong and the penalties are severe: an unlimited fine and up to two years' imprisonment on indictment. This guide explains what HMO landlords need to know.

What Counts as an HMO?

Before a landlord can work out their duties, they need to be clear that the property is actually an HMO, because the definition drives both fire-safety and licensing obligations. In broad terms, a house in multiple occupation is a property occupied by three or more tenants who form more than one household and who share facilities such as a kitchen or bathroom.

That covers the obvious shared houses let to students or young professionals, but also less obvious arrangements: a building converted into separate bedsits with shared access, or a house where the landlord lives with others but the threshold is still met. The exact definition matters because smaller HMOs (typically three or four occupants) and larger ones (five or more, or three storeys) attract different licensing duties, and all attract fire-safety duties under the RRO.

If you are unsure whether your let qualifies, the default safe position is to treat it as an HMO for fire-safety purposes. A fire risk assessment HMO landlords commission protects the tenants and the landlord alike, and the cost of getting the classification wrong is far higher than the cost of the assessment itself.

Who Is the Responsible Person?

Under the RRO, the responsible person for an HMO is normally the person who has control of the premises to the extent that they have control — in practice, the landlord, freeholder or managing agent who lets and manages the property. Where a managing agent is appointed, the duty does not disappear; it is shared, and both parties must cooperate and coordinate.

Tenants have their own limited duties — not to do anything that prejudices fire safety and to co-operate with the landlord — but the legal weight sits with the person controlling the building. That means the landlord is accountable for the means of escape, the fire detection, the maintenance of doors and the clarity of evacuation information.

You can use a competent person under Article 18 to carry out the assessment, but you remain the responsible person and stay liable. A commissioned report that is ignored is no defence. The duty is to ensure a suitable and sufficient assessment is done, recorded where you employ staff, and acted upon — and that applies whether you own one HMO or fifty.

The Fire Safety (England) Regulations 2022

HMO landlords in England must also comply with the Fire Safety (England) Regulations 2022, which added specific duties on top of the RRO, aimed squarely at multi-occupied residential buildings. These rules are now a standard part of any fire risk assessment HMO work.

For buildings containing flats, the regulations require responsible persons to check the fire doors of flat entrances at least every 12 months and the fire doors in common parts at least every three months. Where the top storey of the building is 11 metres or more above ground level, flat-entrance doors must be checked monthly and common-parts doors quarterly.

HMOs with individual rooms rather than self-contained flats are assessed on their own facts, but the door-checking principle — that fire doors are maintained and function — runs throughout. The regulations also require provision of fire-safety instructions to residents and information about the building's external walls where relevant. These are legal duties in their own right, and the assessment should confirm they are being met, not just note them in passing.

What the Assessment Must Cover

A proper HMO assessment, carried out to PAS 79-1:2020 and reflecting BS 9999:2017, has to address the features that make shared housing dangerous: a single shared staircase, multiple locked rooms, and occupants who may not know each other or the building.

The assessor documents ignition sources and fuel loads — overcrowded sockets, cooking in bedrooms, storage in halls — and evaluates who is at risk, including transient tenants and any vulnerable occupant. The means of escape is central: the shared route must be protected, illuminated, signed and kept clear, because everyone in the building depends on the same staircase.

Detection and warning must be adequate for a sleeping risk — interlinked smoke and heat alarms are standard. Fire doors, including those to individual rooms where the layout demands it, must be assessed for integrity. Because HMOs are high-risk, this is Enhanced-tier work, starting at £849 plus VAT.

Licensing and the Housing Act

For many HMOs, fire safety is also enforced through the Housing Act 2004 licensing regime, which dovetails with the RRO rather than replacing it. Local authorities licence larger HMOs — generally those with five or more occupants from more than one household, or three storeys — and condition those licences on adequate fire precautions.

A current, competent fire risk assessment is almost always a licensing requirement, and the local housing team will ask to see it alongside evidence of detection, doors and escape routes. Failure to hold a required licence, or to meet its fire-safety conditions, exposes the landlord to civil penalties, rent repayment orders and, in serious cases, prosecution.

The two regimes — RRO enforced by fire and rescue, and the Housing Act enforced by the council — look at the same building from different angles. A single good assessment satisfies both, provided its action points are closed and its recommendations are kept current. Treating licensing and fire safety as separate jobs is a common and costly landlord mistake.

Common HMO Fire Hazards

The hazards that actually cause HMO fires, and the enforcement findings that follow, are strikingly consistent, and most are about the shared nature of the building rather than any single tenant's behaviour.

Overloaded electrical sockets and illicit cooking in bedrooms are near-universal risks in shared housing, where individuals have limited space and limited concern for the whole building. Storage in hallways and on the shared staircase — bikes, prams, bins — blocks the one escape route everyone relies on, and is one of the fastest routes to an enforcement notice.

Missing or flat interlinked alarms, propped-open fire doors, and tenants who have never been given evacuation information complete the usual list. Good management — clear tenant induction, regular checks, and a current assessment — addresses all of these cheaply. The responsible person who treats the HMO as a collection of rooms rather than a single fire-risk system is the one who ends up before a magistrate.

Conclusion

A fire risk assessment HMO landlords must hold is a legal duty under the RRO 2005, reinforced by the Fire Safety (England) Regulations 2022 and, for licensed properties, the Housing Act 2004. The responsible person — usually the landlord or agent — is accountable for detection, escape routes, fire doors and evacuation information, and HMOs fall into the Enhanced tier from £849 plus VAT. Serious breaches carry an unlimited fine and up to two years' imprisonment on indictment.
