Essential guidance on fire risk assessments for HMOs — from identifying hazards to implementing cost-effective fire safety measures that satisfy licensing requirements.. Understanding HMO Fire Risks Houses in Multiple Occupation (HMOs) present significantly higher fire risks than single family dwellings. Multiple unrelated occupants, shared cooking facilities, varied lifestyles, and often aging building stock create a challenging fire safety environment. The Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to carry out a suitable and sufficient fire risk assessment. What Qualifies as an HMO? Under the Housing Act 2004, a property is an HMO if: It is occupied by three or more persons forming two or more households They share one or more basic amenities (bathroom, toilet, kitchen) It is their only or main residence Rent is payable by at least one occupant Additional licensing applies to larger HMOs (five or more persons forming two or more households). Key Fire Hazards in HMOs Common Ignition Sources Cooking equipment in shared kitchens Portable heaters in bedrooms Smoking materials Overloaded electrical sockets and extension leads Candles and incense E cigarette and lithium battery charging Fuel Sources Accumulation of personal belongings in bedrooms Storage in escape routes and common areas Combustible wall and ceiling linings Upholstered furniture (especially pre 2010 non compliant items) Fire Safety Measures for HMOs Detection and Warning Minimum requirement : LD2 detection system to BS 5839 6 (heat detectors in kitchen, smoke detectors in escape routes and all rooms) Larger HMOs : Consider LD1 system with detection in all rooms Interlinked detectors : All detectors must be interlinked (hardwired or radio linked) Control panel : Grade A system with control panel for licensable HMOs Means of Escape Protected escape routes : 30 minute fire resisting construction to corridors and stairways Fire doors : FD30S self closing fire doors to all rooms opening onto escape routes Emergency lighting : BS 5266 1 compliant emergency lighting in escape routes Travel distances : Maximum 9m to a protected stairway from any bedroom door Final exit doors : Readily openable from inside without keys Compartmentation 30 minute fire separation between: Individual letting rooms Common areas and escape routes Different floors (including ceiling/floor constructions) Fire stopping of all service penetrations Attention to hidden voids and historic alterations Lacors Housing Fire Safety Guide The LACORS Housing — Fire Safety guidance (originally published by CIEH and now adopted widely) provides a consistent framework for fire safety in residential accommodation.
