Rules for french doors in Northern Ireland
Northern Ireland sets replacement door limits through Technical Booklet F1 (2022): 1.8 W/m²K. Replacing external doors does not need full plans or a building notice, but the work must still comply; enlarging an opening or other structural change needs building control approval.
Before ordering: Check with your council planning office before changing the style, material or size of doors, and always for listed buildings, conservation areas and flats.
How it works
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.
- Free survey and a written quote fixed for the specification
- Glass build-up and door U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
