Triple glazing for new builds and self-builds in Derry
New-build triple glazing for homes in Derry: measured on a free survey, made to order and fitted by installation teams working for us across County Londonderry.
Triple glazing that gives your energy calculation headroom. Triple glazing is not required by Building Regulations for new homes, but it helps a new dwelling meet its overall energy target.
Winter light and glass choice in Derry

Rules for new builds and self-builds 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.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions from Derry
Do you supply performance data for SAP?
Yes. Your energy assessor gets the U-values, g-values and frame data for the systems quoted.
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.
How long does it take to get new-build triple glazing fitted in Derry?
After the survey, typical manufacture time is 6 to 12 weeks, and fitting is planned around your build programme.
Do I need permission for new-build triple glazing in Derry?
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.
