Triple glazing for new builds and self-builds in Colwyn Bay
New-build triple glazing for homes in Colwyn Bay: measured on a free survey, made to order and fitted by installation teams working for us across Clwyd.

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 Colwyn Bay

Rules for new builds and self-builds in Wales
For a new home in Wales, windows and doors are approved through the build’s own building control application: the limiting value is 1.4 W/m²K, stricter than England. 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
After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.
- 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
