Why loft conversions trigger fire doors
A two-storey house usually lets people escape from upstairs windows. Once a loft room is added, the top floor is too high for that, so the stair becomes the escape route and has to be protected from the ground floor up. That is why building control often asks for fire doors on rooms off the stair, including existing ground and first-floor rooms, not just the new loft room.
On a typical job that means:
- FD20 or FD30 doors in your chosen style
- Check of which openings need fire doors
- Fire-tested hinges and intumescent strips as required
- Work coordinated with your builder
Which fire door rules apply in Merthyr Tydfil?
Because Merthyr Tydfil is in Wales, we work to the Building Regulations as they apply in Wales and to the Welsh version of Approved Document B. The responsible person duties under the Fire Safety Order 2005 still apply to workplaces and common parts.
England's fire door checking rules for tall residential buildings do not apply in Wales, so the checking frequency for doors in Merthyr Tydfil comes from your fire risk assessment.

Questions
Do you cover CF47 and nearby postcodes?
Yes. We cover Merthyr Tydfil including CF47, and nearby towns such as Aberdare and Rhondda. The survey and written quote are free.
What happens on a survey in Merthyr Tydfil?
We look at every door in scope: the leaf, frame, gaps, seals, hinges, closer, glazing and how the frame is fixed. You then get a written quote that prices each door separately.
Can I just add intumescent strips to my existing doors?
Generally no. A standard internal door is not a fire door, and strips alone will not make it one. Existing doors need to be replaced with certified fire doors.
Do loft conversion fire doors need closers?
Not usually within a single-family house in England. In Scotland, doors onto the protected stair enclosure are expected to be self-closing. Wales and Northern Ireland have their own guidance, and your building control body may ask for something different in particular layouts.
