Fire Door Requirements for Rent to Rent HMOs:
What You Must Install
Fire doors are one of the most critical — and most scrutinised — HMO compliance requirements. Get them wrong and you risk enforcement action, invalid insurance, and serious liability. This guide covers exactly what is required.
What This Guide Covers
Why Fire Doors Are Non-Negotiable in HMOs
HMOs present a significantly higher fire risk than single-family dwellings because multiple unrelated occupants may not know each other’s routines, may not respond quickly in an emergency, and are at greater risk from a fire starting in a communal area or another tenant’s room.
Fire doors provide the critical protection of containing a fire for 30 minutes (FD30 doors) or 60 minutes (FD60 doors) — giving occupants time to escape and the fire service time to respond. For this reason, fire doors are a fundamental requirement in almost every HMO in England.
Fire Door Requirements for HMOs
Fire door requirements for HMOs are set out in the Housing Act 2004 and the HMO Management Regulations 2006, and are guided by the LACORS Fire Safety Guidance. The general requirements for a standard HMO are: For more detail, see the HMO fire safety checklist.
- All bedroom doors — FD30 fire-rated doors (30-minute fire resistance) with smoke seals and self-closing devices
- Kitchen door — FD30 or FD30S (smoke-sealed) fire door with self-closing device
- Communal area doors — typically FD30 fire-rated
- Door frames — must be compatible with the fire door rating. A fire door in a non-fire-rated frame does not provide the required protection
- Intumescent strips and smoke seals — must be fitted to all fire doors
- Self-closers — fire doors must have functioning, properly adjusted self-closing devices
The specific requirements depend on the size, layout, and number of storeys of the HMO. A fire risk assessment by a qualified assessor will specify the exact requirements for your property.
Fire Risk Assessment: Your Starting Point
Before you can be certain of exactly which fire safety measures are required in your HMO, you must carry out a fire risk assessment. This is a legal requirement under the Regulatory Reform (Fire Safety) Order 2005 for HMOs.
- Qualified assessor — the fire risk assessment should be carried out by a competent person. For most HMOs, a professional fire risk assessor with HMO experience is recommended. Cost: typically £150–£350
- The assessment identifies — existing fire risks, the adequacy of current fire precautions (including fire doors), any remedial actions required, and the appropriate fire detection system
- Act on the findings — implement all required actions before tenants occupy. For a new property, schedule the fire risk assessment as part of your setup process, alongside the gas safety check and EICR
Frequently Asked Questions
Do I need fire doors on every door in a rent to rent HMO?
Not necessarily on every door — fire door requirements apply specifically to bedroom doors, the kitchen door, and communal area doors in most HMOs. However, the specific requirements depend on your HMO’s layout, number of storeys, and the findings of a fire risk assessment. Do not guess — get a professional fire risk assessment to identify exactly what is required for your specific property.
How much do fire doors cost to install in an HMO?
A supply-and-fit FD30 fire door including frame, intumescent seals, and self-closer typically costs £350–£650 per door depending on the specification and installer. For a 5-bed HMO, fire door installation (bedroom doors + kitchen) typically costs £2,000–£4,000. Factor this into your refurbishment budget for any new HMO property.
Who is responsible for fire safety compliance in a rent to rent — me or the landlord?
You are — as the rent to rent operator and HMO licence holder, fire safety compliance is your responsibility. Your Company Let Agreement should reflect this. Ensure the property has been properly fire-safety assessed before any tenant moves in, and maintain ongoing compliance throughout the tenancy. For more detail, see HMO licensing requirements.
