Loft conversion fire doors in Cardiff: what's involved
From the CF10 postcode district outwards, we take on loft conversion fire doors across Cardiff for homes, blocks and workplaces.
Cardiff has a broad mix of buildings, including mixed-use office buildings, clinics and purpose-built blocks of flats, and the same fire door principles apply to all of them.
A loft conversion in Cardiff that adds a new storey often brings a building control requirement for fire doors on rooms off the stair. We can fit loft conversion fire doors in Cardiff as your builder's subcontractor or directly for you.
Working with your builder and building control
We can work as a subcontractor to your loft conversion builder or directly for you. We fit doors to match your existing style where certified options exist, and leave product details for building control. Wales, Scotland and Northern Ireland have their own guidance on escape from upper floors; we check which applies to your home.
What you get:
- Fire-tested hinges and intumescent strips as required
- Check of which openings need fire doors
- Work coordinated with your builder
- Product details for building control
Rules and responsibilities in Cardiff
Because Cardiff 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 Cardiff comes from your fire risk assessment.
Which buildings in Cardiff need loft conversion fire doors?
Typical settings for loft conversion fire doors include detached family homes, bungalows gaining an upper floor and semi-detached houses. In Cardiff, as elsewhere, the work is usually commissioned by homeowners, often alongside a builder or after a building control visit, so we fit around the household and leave the product details building control asks for.

Questions
Do you cover CF10 and nearby postcodes?
Yes. We cover Cardiff including CF10, and nearby towns such as Penarth and Caerphilly. The survey and written quote are free.
Can you work from an existing inspection report for my Cardiff building?
Yes. Send it over and we can often price straight from it, then confirm on site. We report back against the same door references so you can close actions off.
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.
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.
