HMO Fire Door Requirements: What Landlords Must Fit (and What It Costs)
By Sebastian Grabowski, DC Fire & Security, Luton. Updated October 2026.
What fire doors does an HMO need?
Most councils expect every door opening onto an HMO's escape route, usually bedrooms, kitchen and living room, to be an FD30S fire door with a self-closer and a thumb-turn lock. The baseline is the LACORS fire safety guide (July 2008), used alongside the Housing Act 2004, but each council sets its own licensing standard, so check yours first.
Which doors in an HMO need to be fire doors?
Every door from a risk room onto the escape route: bedrooms, kitchen, living room and any cellar or understairs cupboard. Bathrooms and WCs usually do not, LACORS says (paragraph 15.6), unless they contain a risk such as a heater or storage.
The doors, the 30-minute walls and ceilings around the hall and stairs, and the fire alarm work together as one protected route. A licensing officer looks at them as a system, not door by door. A Victorian fanlight over a bedroom door, for example, can undo a perfectly good fire door underneath it.
| Room or door | Usual council standard | Notes |
|---|---|---|
| Bedroom onto hall or landing | FD30S, self-closer, thumb-turn lock | Covers almost every bedroom in a shared house |
| Kitchen | FD30S, self-closer | The highest-risk room in most HMOs |
| Living room on the escape route | FD30S, self-closer | Same as a bedroom |
| Bathroom or WC | Usually no fire door needed | Unless it holds a heater, storage or another risk |
| Cellar or understairs cupboard | FD30S, kept shut or locked | Cellar needs 30-minute separation from the route |
| Final exit door | Not normally a fire door | Must open from inside without a key (LACORS 16.1) |
| Glazing over or beside route doors | Fire-rated glass or protected | Fanlights are a common miss |
Does the type and size of HMO change the rules?
Yes. LACORS accepts sound, close-fitting conventional doors in a low-risk shared house of up to two storeys, but expects FD30S doors to every risk room in a bedsit-type HMO of any height. Many councils go further and ask for FD30S self-closing doors in every licensed HMO.
Mandatory licensing applies to HMOs with 5 or more people forming 2 or more households. Many councils also run additional licensing schemes for smaller HMOs. An unlicensed shared house can still be assessed under the Housing Health and Safety Rating System (HHSRS) in the Housing Act 2004.
Standards do not carry over between councils, or even between two houses on the same street. Long travel distances, poor construction or an inner room can push a house into a higher standard.
| Type of HMO | LACORS baseline for room doors | Self-closers |
|---|---|---|
| Shared house, up to 2 storeys | Sound, close-fitting conventional doors, unless higher risk | Not always required |
| Shared house, 3 to 4 storeys | 30-minute protected route with FD30 doors to risk rooms | Depends on the risk assessment |
| Shared house, 5 to 6 storeys | FD30S doors with smoke seals to all risk rooms | Usually |
| Bedsit-type HMO, any height | FD30S doors to all risk rooms | Always (LACORS 21.5) |
What do licensing officers check on HMO fire doors?
Closers, locks and seals come first: does each door close fully into its frame, open from inside without a key, and have intact, unpainted seals? In our inspections, seal faults were 35% of all door faults and closer faults 13%.
Disconnected closers are the classic tenant sabotage. LACORS says fire doors in multi-occupied houses should normally have approved self-closing devices (closers to BS EN 1154 are the usual choice) and should never be propped or wedged open. A free-swing closer can stop the slamming that makes tenants disconnect them. See our fire door inspection statistics for the full fault breakdown.
- A thumb-turn on the inside of every lockable route door, no key needed to get out
- Closers that pull the door shut into the frame from any angle
- Continuous intumescent strips and smoke seals, not painted over
- Edge gaps of roughly 3mm, and no more than 4mm
- Cellar and cupboard doors shut and secured, never wedged
- Fire door signs where the council's standard asks for them
Can existing HMO doors be repaired or upgraded?
Existing fire doors can usually be repaired. Upgrading a door that was never a fire door is different: LACORS says it should be avoided wherever possible (paragraph 21.8), and a tested doorset is always preferable.
A new fire door leaf in the existing frame is acceptable only if the frame is sound and matches the tested specification (LACORS 21.7). Hollow "egg-box" doors, flimsy panel doors and non-fire glazed doors should not be accepted at all.
For doors that are already fire doors, repair is usually the answer. Across three of our programmes, 95% of failed doors were repaired rather than replaced (see our inspection statistics). See fire door repairs for the common fixes.
How much do HMO fire doors cost?
A basic certified FD30S doorset fitted starts from about £1,000 + VAT, and a new fire door leaf in a sound existing frame is typically £600 to £1,600 fitted. Repairs to existing fire doors are usually £150 to £900 a door.
The price per door falls when the whole schedule is done on one visit rather than piecemeal. For more detail, see our guides to fire door supply and fit costs and fire door remedial costs.
| Work | Typical price, + VAT |
|---|---|
| Fire door inspection | From about £250 for a small building, typically £20 to £30 a door on larger ones |
| Repairs to an existing fire door | Usually £150 to £900 a door, depending on the fault and how many doors are done on one visit |
| New overhead closer, fitted | Typically £100 to £250 |
| New intumescent and smoke seals, fitted | Typically £30 to £150 a door |
| New fire door leaf in existing frame | Typically £600 to £1,600 fitted |
| Certified FD30S doorset, fitted | From about £1,000, rising to £3,000 or more for glazed or premium doorsets |
Who is responsible for fire doors in an HMO?
The landlord, licence holder or manager. The Fire Safety Order 2005 covers the shared parts of an HMO, and the Management of HMOs Regulations 2006 require the manager to keep the means of escape in good order and repair.
The council enforces housing standards and licence conditions; the fire and rescue service enforces the Fire Safety Order. For the wider picture, alarms included, read our HMO fire safety guide for landlords.
We inspect and repair fire doors across Bedfordshire, Hertfordshire, London, the Thames Valley and the East Midlands.
