Fire Safety Requirements for HMOs — Complete Landlord Guide

HMO landlords face strict fire safety obligations. This guide covers the alarm grades, emergency lighting, extinguisher requirements and what inspectors look for.

What Is an HMO?

A House in Multiple Occupation (HMO) is a property rented by at least three people who are not from the same household but share facilities such as a bathroom or kitchen. HMOs of five or more people from two or more households require a mandatory HMO licence from the local authority. Fire safety is a mandatory condition of licensing.

Fire Alarm Requirements for HMOs

The standard fire alarm requirement for most licensed HMOs is a Grade D, LD2 system — mains-powered, interlinked smoke alarms on all escape routes (hallways, landings) and in high-risk rooms (kitchen, living room), with battery backup. Larger HMOs (typically three or more storeys, or five or more occupants) may require a Grade A system — a full addressable panel-based system equivalent to a commercial fire alarm. Your local authority will specify the requirement as a condition of licensing.

Emergency Lighting for HMOs

Larger HMOs — particularly those of three or more storeys — are likely to require emergency lighting on escape routes under BS 5266. Emergency lighting ensures escape routes are illuminated if the mains power fails during an emergency. Monthly and annual tests must be carried out and recorded.

Fire Extinguishers in HMOs

Fire extinguishers are not always mandatory in domestic HMOs, but they are strongly recommended and may be required by your local authority or insurer. At minimum, a fire blanket should be provided in the kitchen. In larger or higher-risk HMOs, a CO2 extinguisher near electrical equipment and a water or foam extinguisher in communal areas is advisable.

Fire Doors and Compartmentation

HMOs require fire-rated doors on all habitable rooms that open onto escape routes. Doors must be self-closing and fitted with intumescent strips and cold smoke seals. Fire door inspections should be carried out regularly — FireJet provides fire door inspections and installations across the Northwest.

What Do HMO Inspectors Look For?

Local authority inspectors will check: fire alarm grade and category, detector locations, alarm test records, emergency lighting provision and test records, fire door condition and self-closers, escape route clearance, and whether a current fire risk assessment is in place. FireJet can help you prepare for an HMO inspection with a full fire safety survey. Call 0330 043 0646.
