Who needs a fire risk assessment?
The Regulatory Reform (Fire Safety) Order 2005 (RRO 2005) requires a fire risk assessment for all non-domestic premises and for the common parts of residential buildings containing two or more dwellings. This means every HMO landlord, every owner or manager of a block of flats, every commercial property occupier, and every operator of a care home, school, or office is legally required to have a current fire risk assessment.
Private single-let dwellings — a house or flat let to a single household — are exempt from the RRO 2005. However, the landlord still has obligations under the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 to install smoke alarms on every storey and a carbon monoxide alarm in any room with a fixed combustion appliance.
London has a particularly high proportion of converted Victorian properties let as HMOs. These buildings — originally designed as single-family homes with open staircases, timber floors, and thin partition walls — present specific fire separation challenges. Many London HMO landlords require structural fire separation works as a result of their FRA, including fire-rated ceilings, fire doors, and additional means of escape.

HMO fire safety requirements
HMO fire safety in London
Smoke alarm requirements (2022 regulations)
The Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 require a smoke alarm in every room used as sleeping accommodation in an HMO — not just on each storey. This extended the previous requirement and applies to all HMOs from 1 October 2022. All smoke alarms in HMOs must be interlinked so that an alarm on any floor triggers all alarms throughout the property.
A heat detector is required in the kitchen in addition to a smoke alarm, as cooking activity can cause false activations from smoke alarms in this location. The heat detector must also be interlinked to the alarm system.
Fire doors in HMOs
Fire doors (FD30 — 30 minutes fire resistance) are required to bedroom doors and to the kitchen door in HMOs. The door must carry a BS 476 Part 22 or BS EN 1634-1 certification label, have intumescent strips and cold smoke seals, and be fitted with a self-closing device. Maximum gap tolerances are 3mm at the sides and top and 8mm at the bottom.
London HMOs in converted Victorian properties frequently require fire door upgrades as part of the FRA action plan. Original Victorian internal doors — typically ledged-and-braced 4-panel doors — do not provide adequate fire separation. Replacement with compliant FD30 doors is usually required.
Emergency lighting
Larger HMOs — typically those with three or more storeys or a total floor area over 200 square metres — are required to have emergency lighting in all escape routes and communal areas. Emergency lighting must be tested monthly (a brief function test) and annually (a full 3-hour duration discharge test). Records must be maintained. Emergency lighting failure in an HMO is both an HMO licensing breach and a fire safety offence.
London-specific challenges
The majority of London HMOs are in converted Victorian terraced houses with open timber staircases, original lath-and-plaster ceilings, and thin internal partitions. These buildings require specific fire separation measures — fire-resisting plasterboard linings to ceilings and staircases, intumescent paint on structural timbers, and fire-rated boarding to understairs cupboards. A thorough FRA will identify all of these and prioritise them in the action plan.
Assessment outcomes
Fire risk assessment outcomes explained
Satisfactory
The premises are adequately protected against fire risk. No immediate action is required, though recommendations for improvement may still be included. The responsible person should review the assessment after any significant change to the building or its use.
Action required
Specific improvements are needed to bring the premises to an adequate standard. The report will list actions with a recommended timescale — some may be immediately required; others may be scheduled. The FRA is re-issued as satisfactory once actions are completed.
Unsatisfactory
Immediate action is required. The premises present an unacceptable fire risk. The responsible person must take urgent steps to reduce the risk — which may include prohibiting use of part or all of the premises until remedial works are complete. The fire authority may issue an Enforcement Notice.

Common questions
Fire risk assessment Merton: frequently asked
Who is required to have a fire risk assessment?
The Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for all non-domestic premises and for the common parts of residential buildings with two or more dwellings. In Merton, this means all HMO landlords, owners and managers of blocks of flats (for the common areas), commercial property occupiers, offices, care homes, and schools. Private single-let dwellings are exempt from the RRO 2005 but must comply with smoke and carbon monoxide alarm regulations.
How often should an HMO fire risk assessment be done?
A fire risk assessment should be reviewed whenever there is a significant change to the building, its use, or the number of people at risk. For most HMOs in Merton, an annual review is recommended as good practice. The assessment must also be reviewed after a fire or near-miss incident. The FRA review should also be triggered by any change to the fire detection system, means of escape, or fire door provision. We cover all Merton areas including Wimbledon, Mitcham, Morden, Raynes Park.
What is included in a fire risk assessment report?
A fire risk assessment report documents the five steps of the RRO 2005 assessment process: identification of fire hazards, identification of people at risk, evaluation and reduction of risk, recording findings, and review. The report includes the assessor details and qualifications, the date of assessment, the overall risk rating (satisfactory, action required, or unsatisfactory), and a prioritised action plan with recommended timescales for each required improvement.
