Rules in Northern Ireland
The rules for replacement windows in Northern Ireland are set by Technical Booklet F1 (2022): 1.6 W/m²K, or a Window Energy Rating of band C or better. Replacing windows or 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 windows or 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.
- Guide prices published, not hidden
- No pressure: the quote is yours to keep
- Frames, glass and fitting in one contract
- Advice on planning and consents before you order
Questions
Is triple glazing good for a flat on a busy road?
Yes, especially with an acoustic laminated pane, which makes the bigger difference to noise.
What about tall blocks?
Higher-risk buildings (18 m or 7 storeys and over in England) have extra building safety requirements. Talk to your building’s accountable person first.
Do I need permission to replace windows in my flat?
Often, yes. In England and Wales flats have no householder permitted development rights, so check with the council; in Scotland permission is generally needed only if the opening size changes or the flat is in a conservation area; in Northern Ireland ask your council. Separately, check your lease (England, Wales and Northern Ireland) or title deeds and factor (Scotland).
