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

U-values, g-values and installation details for your assessor. 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 Swansea
By midsummer Swansea has about 16 h 40 min of daylight, but in December only around 7 h 49 min, with the noon sun at about 15°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

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
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
