Fire safety in Houses in Multiple Occupation (HMOs) is critical to protect tenants and property. Many landlords and property managers face challenges meeting the required standards, which can lead to serious safety risks and legal issues. This post explains the typical fire safety expectations for HMOs, highlights common fail points, and shows how professional support can ensure compliance and safety.

Typical Fire Safety Expectations for HMOs
Typical Fire Safety Expectations for HMOs
Local authorities and FRAs normally require HMOs to have a mains-powered, interlinked fire detection system to BS 5839-6. For many shared-house HMOs this is Grade D1 with smoke detection in escape routes on every storey, plus a smoke alarm in the living room/lounge and any other high-risk areas, and a heat alarm in the kitchen. All alarms must be interlinked so activation of one sounds all units.
Lower-risk HMOs may sometimes be accepted with LD3 coverage, while bedsit-type HMOs or higher-risk properties may need LD1 or a Grade A panel system. The required grade and coverage are confirmed by the Fire Risk Assessment and local authority licensing standard.
Meeting these standards ensures early fire detection and clear warning signals, giving tenants the best chance to escape safely.
Common Fire Safety Fail Points in HMOs
Many HMOs fail to meet fire safety standards due to avoidable mistakes. Some of the most frequent issues include:
Alarms not interlinked
When alarms are not connected, only one alarm sounds during a fire, leaving other areas unaware. This can delay evacuation and increase risk.
Smoke alarms placed inside kitchens
Smoke alarms in kitchens often trigger false alarms from cooking fumes. Tenants may disable these alarms, which removes critical protection.
Inadequate coverage of escape routes
Some HMOs only install alarms in escape routes, but LD2 standards require coverage in escape routes and living rooms. Insufficient coverage leaves tenants vulnerable.
Poor maintenance and testing records
Fire alarm systems must be regularly maintained and tested by a competent person. Lack of proper records or maintenance can mean alarms fail when needed most.
These fail points often result from misunderstanding regulations or cutting corners during installation and upkeep.
How Professional Support Ensures Fire Safety Compliance
Professional fire safety services help landlords and managers meet the correct standards by:
Installing the appropriate Grade and LD category alarms based on a Fire Risk Assessment
Ensuring all alarms are properly interlinked for full coverage
Providing regular maintenance and testing by qualified technicians
Keeping detailed records to demonstrate compliance with legal requirements
This approach reduces the risk of fire-related incidents and avoids costly enforcement actions from local authorities.
Practical Tips for Landlords and Managers
To maintain fire safety in HMOs, consider these practical steps:
Always follow the Fire Risk Assessment recommendations for alarm types and placement
Avoid installing smoke alarms inside kitchens; use heat alarms instead
Check that all alarms are interlinked and test regularly
Keep clear, up-to-date maintenance and testing logs
Use professional services for installation and ongoing system checks
These actions protect tenants and help landlords meet their legal duties under fire safety legislation.
