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.

Rules for new builds and self-builds in England
For a new home in England, windows and doors are approved as part of the build’s own building control application, not as replacements: the limiting value is 1.6 W/m²K, with 1.2 used for the design reference. 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
