What Is A Fire Door?
A fire door is a specially certified door designed to resist the spread of fire and smoke for a specified time — typically 30 or 60 minutes. Fire doors are legally required in many UK properties including HMOs, flats, commercial buildings and houses with specific features like loft conversions or integral garages.
FD30 vs FD60 — Which Do You Need?
FD30S (30 Minute)
Provides 30 minutes of fire resistance. The "S" means smoke seals are fitted — legally required in residential properties. FD30S is the most common fire door in UK HMOs, flats and houses.
FD60 (60 Minute)
Provides 60 minutes of fire resistance. Required for higher-risk areas including high-rise buildings over 18m, plant rooms, commercial kitchens and certain stairwells.
| Property Type | Fire Door Required |
|---|---|
| HMO (3+ occupants) | FD30S on all bedrooms and escape route |
| Flat in block under 11m | FD30S on entrance door |
| Flat in block over 11m | FD30S entrance, possibly FD60 |
| House with loft conversion | FD30S on escape route doors |
| House with integral garage | FD30S on garage-to-house door |
| Commercial building | FD30S or FD60 depending on use |
