Landlord Fire Risk Assessment Guide UK 2026 — HMOs and Blocks of Flats

A complete guide for UK landlords to the fire risk assessment (FRA) obligation under the Regulatory Reform (Fire Safety) Order 2005: when required, what it must cover, competent assessors, review frequency, and enforcement by fire authorities.

The Regulatory Reform (Fire Safety) Order 2005 requires the responsible person of non-domestic premises to carry out a 'suitable and sufficient' fire risk assessment. For landlords, this applies to HMOs (the whole property), the common parts of blocks of flats (entrance hall, corridors, stairwells), and any other multi-occupancy premises with shared areas.

Criminal offence

Failure to carry out an FRA, or carrying out an inadequate FRA, is a criminal offence under the RRO 2005. Penalties: unlimited fine on Crown Court conviction, up to two years' imprisonment. Fire authorities can also serve Prohibition Notices immediately closing the premises.

When an FRA is required

  • All HMOs (entire property — all rooms and communal areas)
  • Common parts of any block of flats (corridors, stairwells, plant rooms, roof voids, entrance lobby)
  • Shared-access buildings even if below HMO threshold
  • Self-contained houses let to a single family: domestic premises, RRO 2005 does not apply — but smoke alarm regulations still apply

What the FRA must cover

  • Identification of fire hazards: ignition sources, fuel sources, oxygen sources
  • Identification of people at risk and their vulnerabilities
  • Evaluation of existing controls and adequacy of escape routes, fire doors, emergency lighting, alarm systems
  • Written action plan with timescales
  • For blocks over 11m (Fire Safety (England) Regulations 2022): monthly lift checks, quarterly fire door checks also required

Frequently asked questions

Do I need a fire risk assessment for a 4-tenant HMO?+

Yes. Any HMO is non-domestic premises for RRO 2005 purposes regardless of size. You must carry out and record a suitable and sufficient FRA. For a simple HMO with a straightforward layout, a trained landlord may carry out a self-assessment, but professional assessment is strongly recommended given the criminal penalties for non-compliance.

How often must I review the fire risk assessment?+

The RRO 2005 does not specify a fixed period. In practice, annual review is the accepted standard for HMOs. Review must also be carried out after any material change to the property (works, change of use, new occupants with vulnerabilities) or after any fire or near-miss.
