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

We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.

  • Guide prices published, not hidden
  • No pressure: the quote is yours to keep
  • Frames, glass and fitting in one contract

Questions from Lisburn

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.

How long does it take to get new-build triple glazing fitted in Lisburn?

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 Lisburn?

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.
