FD30 fire doors for Kent buildings
Whether your building is in Maidstone, Gillingham or a smaller place in Kent, we can provide FD30 fire doors with the same evidence-led approach.
For a mixed portfolio in Kent, we can survey every FD30 opening in one visit and price leaf-only and doorset options side by side. In Kent, FD30 doors are the usual choice for escape-route corridors, stairs and kitchen doors where the fire strategy asks for 30 minutes.
Kent has a mix of buildings, from purpose-built blocks to converted houses and commercial premises. We tailor the programme to the building, not the other way round.
What does a correct FD30 installation include?
A typical timber FD30 leaf is around 44mm thick and hangs on at least three fire-tested hinges. The gaps between leaf and frame are set to the manufacturer's data, usually around 3mm. Intumescent strips, and smoke seals where needed, go in the frame or leaf edge as specified. The closer must pull the door shut and latch it from any angle. Every hole cut for a lock, latch or hinge is lined with intumescent material where the certification calls for it.
Then comes the part that is often skipped: sealing the gap between the frame and the wall with a tested material, as BS 8214:2026 now sets out in more detail.
The regulations behind fire doors in Kent
The rules that apply to fire doors in Kent 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 Kent 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.
The steps on a Kent installation
- Measure the opening, check the frame and confirm the rating needed
- Order a certified leaf or doorset to size, with matching components
- Remove the old door and assess the frame or structural opening
- Fix the frame and hang the leaf to the certified gap tolerances
- Fit seals, hinges, latch, closer and signage, then test close-and-latch
- Seal the frame-to-wall gap, make good and record the evidence
Budgeting for FD30 fire doors in Kent
As a guide, budget £300–£600 for a leaf into a sound existing frame; £650–£1,300 for a doorset, ex VAT for FD30 fire doors. The figure for your Kent building depends on the number of doors, the rating, the condition of the frames, finishes, hardware and access. We confirm a fixed price after the free survey.
Questions
Do you provide FD30 fire doors across Kent?
Yes. We cover all of Kent, including Maidstone and Gillingham. Surveys and written quotes are free.
Can a new FD30 door go into my old frame?
Sometimes. The frame has to be sound, square, securely fixed and compatible with the new leaf's certification. Many older frames are not, especially softwood linings or frames altered for previous doors. We check each frame on the survey and recommend a doorset only where the frame cannot be relied on.
How long does it take to fit an FD30 door?
A leaf into a sound frame is often a few hours. A full doorset including frame removal, fixing, sealing and making good is usually half a day to a day per opening, depending on access and the wall construction.
