What Are Fire Door Regulations In The UK?
Fire door regulations in the UK are governed. Related: fire door inspection checklist | fire doors UK buyers guide.
Fire door regulations in the UK are governed by several pieces of legislation working together. The primary laws are the Regulatory Reform (Fire Safety) Order 2005 and the Fire Safety (England) Regulations 2022, which came into force following the Grenfell Tower tragedy.
In simple terms: if you own or manage a property where people live or work, you are legally responsible for ensuring fire doors meet the required standard — and are inspected regularly.
The Law In Plain English
Under the Fire Safety (England) Regulations 2022, landlords of buildings over 11 metres must inspect communal fire doors every 3 months and flat entrance doors every 12 months. Failure to comply = prosecution, unlimited fines and potential imprisonment.
The Property Types That Matter Most
HMOs and shared houses
If you manage an HMO, fire doors are usually part of the wider protection of the escape route. The exact specification depends on the building and the risk, but the practical rule is simple: do not assume an ordinary internal door is enough.
Flat blocks and communal buildings
In blocks, flat entrance doors and communal doors matter because they protect corridors, lobbies and stairways. This is where the 3-month and 12-month inspection rhythm becomes especially important for buildings over 11 metres.
Single private houses
A single private house is different from an HMO or a building with common parts. The right fire-door route depends on layout, conversion work, integral garages and the overall fire strategy of the home.
What A Basic Fire Door Check Looks For
- Whether the door is damaged or has been altered badly
- Whether it closes properly into the frame and latches fully
- Whether the gaps are too large around the sides, top or threshold
- Whether hinges, self-closers, signage, glazing and seals are suitable
- Whether the opening needs remedial work or a full replacement route
When Repair Becomes Replacement
Not every defect means a new door. Some issues are remedial: worn seals, missing ironmongery, a failed closer or poor latching. But if the door, frame or opening is fundamentally wrong for the job, replacement is often the safer and cleaner route.
Practical rule: identify the building type, check the inspection duty, inspect regularly, record defects clearly and arrange repairs or replacements quickly using a competent contractor.
Who Needs A Fire Door In London?
HMO Landlords (Houses in Multiple Occupation)
This is the most common requirement in London. If you rent a property to 3 or more people from different households, you almost certainly need FD30S fire doors on every habitable room that opens onto the shared escape route.
- All bedroom doors in an HMO — FD30S required
- Kitchen doors in HMOs — FD30S required
- Living room doors if on escape route — FD30S required
- Bathroom doors — typically FD20 or self-closing standard door
Purpose-Built Flats
- Flat entrance doors — FD30S minimum
- Any door opening onto communal staircase — FD30S
- Buildings over 11m — quarterly inspection mandatory
Houses With Loft Conversions
- All doors on the new escape route — FD30S required
- This includes every floor from loft to ground floor exit
- Building Regulations Part B applies automatically
Houses With Integral Garages
- Door between garage and living accommodation — FD30S required
- Must be self-closing
- No glazing permitted unless fire-rated
| Property Type | Fire Door Required | Standard | Inspection Frequency |
|---|---|---|---|
| HMO (3+ people) | ✓ Yes | FD30S | Annual minimum |
| Purpose-built flat (under 11m) | ✓ Yes | FD30S | Annual |
| Purpose-built flat (over 11m) | ✓ Yes | FD30S/FD60 | Quarterly |
| Loft conversion | ✓ Yes | FD30S | Annual |
| House with integral garage | ✓ Yes | FD30S | Annual |
| Standard 2-storey house | ✗ Not required | N/A | N/A |
| Commercial building | ✓ Yes | FD30S/FD60 | Annual minimum |
FD30 vs FD60 — What's The Difference?
FD30S Fire Doors
FD30S doors provide 30 minutes fire resistance. The "S" stands for smoke — meaning smoke seals are included, which is legally required in residential properties. These are the most common fire doors in London HMOs and flats.
FD60 Fire Doors
FD60 doors provide 60 minutes fire resistance. Required in higher-risk locations including high-rise buildings over 18 metres, plant rooms, commercial kitchens, server rooms and certain stairwell enclosures.
⚠️ Common Mistake: Many landlords fit FD30 doors without smoke seals. The "S" in FD30S is not optional in residential properties — smoke kills faster than fire. All residential fire doors must include smoke seals.
What Must A Compliant Fire Door Include?
A legally compliant fire door installation in London must include all of the following:
- Certified fire door leaf — must carry a certification label (CERTIFIRE, BWF, BM TRADA or similar)
- Intumescent strips — expand in heat to seal the gap between door and frame
- Smoke seals — brush or rubber seals to prevent smoke passage (mandatory for residential)
- Fire-rated hinges — minimum 3 hinges, all fire-rated grade
- Self-closing device — required in HMOs and most residential applications
- Fire-rated frame — the frame must also be fire-rated, not just the door leaf
- Correct gap tolerance — maximum 3mm gap around door edges (4mm at threshold)

Frequently Asked Questions
Does my landlord have to fit fire doors?
Yes, if the property is an HMO or if it is a purpose-built flat. Your landlord is legally responsible for fire door compliance under the Regulatory Reform (Fire Safety) Order 2005.
Can a standard door be converted to a fire door?
No. You cannot convert a standard door to a certified fire door by adding strips or seals. A fire door must be a certified complete assembly — door leaf, frame, hardware and seals — all specified together. Doorz London supplies complete certified assemblies.
