Loft conversion fire doors for Redhill buildings
We provide loft conversion fire doors in Redhill (RH1 and the surrounding postcodes), from the first survey through to a documented handover.
Buildings in and around Redhill range from schools to HMOs and family homes after loft conversions. Whatever the building, the standard is the same: certified products, correct gaps, seals and closers, and a frame sealed to the wall.
For homes in Redhill, we match fire doors to your existing style wherever certified options allow. A loft conversion in Redhill that adds a new storey often brings a building control requirement for fire doors on rooms off the stair.
FD20 or FD30?
In England, the guidance generally asks for FD20 (E20) doors in this situation, and self-closers are not usually required within a house. Scotland is different: the domestic Technical Handbook expects doors onto the protected stair enclosure to be self-closing fire doors, so closers are part of the job there. Many homeowners choose FD30 doors anyway, because they are widely available and the price difference is small. Either way, the door must be fitted properly: correct gaps, fire-tested hinges and an intumescent strip where the product requires one.
Each installation includes:
- FD20 or FD30 doors in your chosen style
- Frame repairs or new linings where needed
- Product details for building control
- Work coordinated with your builder
Which fire door rules apply in Redhill?
The rules that apply to fire doors in Redhill are England's. The responsible person under the Regulatory Reform (Fire Safety) Order 2005 must keep fire doors in non-domestic premises and the common parts of flats in working order; the Fire Safety Act 2021 confirmed that this includes flat entrance doors onto common parts.
Where a Redhill block is above 11 metres, regulation 10 of the 2022 regulations means communal doors are checked every three months and flat entrance doors annually on a best-endeavours basis. Replacement doors must also satisfy the Building Regulations, with Approved Document B as the guidance most building control bodies work from.

Questions from Redhill
Do you cover RH1 and nearby postcodes?
Yes. We cover Redhill including RH1, and nearby towns such as Reigate and Horley. The survey and written quote are free.
Can you work from an existing inspection report for my Redhill building?
Yes. Send it over and we can often price straight from it, then confirm on site. We report back against the same door references so you can close actions off.
Can I just add intumescent strips to my existing doors?
Generally no. A standard internal door is not a fire door, and strips alone will not make it one. Existing doors need to be replaced with certified fire doors.
Do all my doors need to be fire doors after a loft conversion?
Usually the doors from habitable rooms onto the stair do, on every floor. Bathrooms are often excluded. Building control decides for your house.
