FD30 fire doors in Wiltshire: what's involved
We provide FD30 fire doors across Wiltshire, covering 4 towns and 26 postcode districts, including Swindon, Salisbury and Trowbridge.
In Wiltshire, 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 Wiltshire, we can survey every FD30 opening in one visit and price leaf-only and doorset options side by side.
Fire door work in Wiltshire 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 Wiltshire
Fire doors in Wiltshire fall under English rules. New and replacement doors are covered by the Building Regulations 2010 and Approved Document B. In workplaces and the common parts of blocks, the Regulatory Reform (Fire Safety) Order 2005, as clarified by the Fire Safety Act 2021, puts the duty on the responsible person to keep fire doors suitable and maintained.
For residential buildings in Wiltshire above 11 metres, regulation 10 of the Fire Safety (England) Regulations 2022 adds checks: communal fire doors at least every three months and best-endeavours checks of flat entrance doors at least every twelve months. Higher-risk buildings of at least 18 metres or seven storeys also come under the Building Safety Act 2022, where works may need approval from the Building Safety Regulator.

- Remove the old door and assess the frame or structural opening
- Fix the frame and hang the leaf to the certified gap tolerances

FD30 fire doors questions
Do you provide FD30 fire doors across Wiltshire?
Yes. We cover all of Wiltshire, including Swindon and Salisbury. 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.
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.
