Rules in Northern Ireland
For a new home in Northern Ireland, windows and doors are approved through the build’s full plans application to council Building Control: they must average 1.40 W/m²K, with no single unit worse than 3.00. The house itself needs planning permission.
VAT: supply and fitting by a VAT-registered contractor in the construction of a new home is normally zero-rated, so new-build guide prices are shown without VAT; supply-only purchases carry 20% VAT, which self-builders can usually reclaim through HMRC’s DIY housebuilders scheme.
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 whole-window U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
Questions

For about 22 m² of windows and doors, our guide starts at £11,195 in uPVC and £18,895 in aluminium, fitted and zero-rated (new home).
Is triple glazing mandatory for new builds?
No. Neither the current rules nor the Future Homes Standard make it compulsory. Triple glazing helps meet the overall energy target.
Can you price from drawings?
Yes. Send your drawings or window schedule and we will price a package, then confirm sizes on site before manufacture.
Do you cover all of County Down?

Do I need permission for new-build triple glazing in Northern Ireland?
In Northern Ireland, a new home needs planning permission, and its windows and doors are approved through the build’s own Building Regulations application rather than as replacements.
