Getting FD30 fire doors right in Cornwall
Whether your building is in Redruth, Falmouth or a smaller place in Cornwall, we can provide FD30 fire doors with the same evidence-led approach.
Each FD30 leaf we supply for Cornwall is sized for the opening, rather than trimmed beyond what its certification allows. For a mixed portfolio in Cornwall, we can survey every FD30 opening in one visit and price leaf-only and doorset options side by side.
Fire door work in Cornwall spans housing providers with large estates, individual landlords, businesses and homeowners. We price every job from a survey, never from a list price alone, because the condition of the frames and the hardware makes a real difference.
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 Cornwall
The rules that apply to fire doors in Cornwall 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 Cornwall 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.

Common questions
Do you provide FD30 fire doors across Cornwall?
Yes. We cover all of Cornwall, including Redruth and Falmouth. Surveys and written quotes are free.
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.
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.
