Getting FD30 fire doors right in Cambridge
We provide FD30 fire doors in Cambridge (CB2 and the surrounding postcodes), from the first survey through to a documented handover.
Cambridge has a broad mix of buildings, including care homes, offices and industrial units, and the same fire door principles apply to all of them.
In Cambridge, FD30 doors are the usual choice for escape-route corridors, stairs and kitchen doors where the fire strategy asks for 30 minutes. For a mixed portfolio in Cambridge, we can survey every FD30 opening in one visit and price leaf-only and doorset options side by side.
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.
On a typical job that means:
- Survey of the opening, frame and existing ironmongery
- Frame-to-wall gap sealed with an evidenced material
- Certified FD30 or FD30S leaf, or full doorset
- Overhead closer set to close and latch
Rules and responsibilities in Cambridge
The rules that apply to fire doors in Cambridge 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 Cambridge 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.
Where FD30 fire doors fit in Cambridge
Typical settings for FD30 fire doors include schools, shops and blocks of flats. In Cambridge, as anywhere, the duty holder varies: a responsible person for a workplace, a landlord or managing agent for a block or HMO, or a homeowner after building work. We adjust access, timing and paperwork to suit whoever commissions the work.
The steps on a Cambridge 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

Questions from Cambridge
Is Cambridge within your coverage area?
It is. We cover Cambridge in Cambridgeshire and neighbouring towns such as Newmarket. There is no charge for the survey.
How quickly can you survey in Cambridge?
It depends on the number of doors and access, but we offer survey dates as soon as we reply to your enquiry. If an inspection has found urgent safety issues, tell us and we'll prioritise.
Do FD30 doors need a closer?
Most do. Doors on escape routes, flat entrance doors and doors in the common parts of buildings need a self-closing device that shuts and latches the door. Some doors inside houses and locked riser doors are exceptions, depending on the fire strategy.
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.
