FD30 fire doors: our service in Cambridgeshire
Across Cambridgeshire, from Peterborough to Cambridge, we survey, supply and fit FD30 fire doors for homes, blocks of flats and workplaces.
Each FD30 leaf we supply for Cambridgeshire is sized for the opening, rather than trimmed beyond what its certification allows. In Cambridgeshire, FD30 doors are the usual choice for escape-route corridors, stairs and kitchen doors where the fire strategy asks for 30 minutes.
Cambridgeshire 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.
Which fire door rules apply in Cambridgeshire?
In Cambridgeshire, as elsewhere in England, the starting point is the Fire Safety Order 2005: whoever controls a workplace or the shared parts of a residential block must make sure its fire doors work. When doors are replaced, the Building Regulations and Approved Document B set the standard the new work has to meet.
Blocks above 11 metres have a specific routine under regulation 10 of the Fire Safety (England) Regulations 2022: quarterly checks of communal fire doors and annual best-endeavours checks of flat front doors. If your Cambridgeshire building is a higher-risk building under the Building Safety Act 2022, we confirm the approval route with the Principal Accountable Person before any work is ordered.

Common questions
Do you provide FD30 fire doors across Cambridgeshire?
Yes. We cover all of Cambridgeshire, including Peterborough and Cambridge. Surveys and written quotes are free.
What is the difference between FD30 and FD30S?
FD30S has been tested for smoke control as well as fire. It adds a smoke seal, usually a brush or blade, and needs a tight threshold gap. Flat entrance doors and doors onto protected escape routes are commonly specified as FD30S.
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.
