Rules 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
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
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.
Do you supply performance data for SAP?
Yes. Your energy assessor gets the U-values, g-values and frame data for the systems quoted.
Do you cover all of Greater London?
We arrange surveys and fitting across Greater London.
Do I need permission for new-build triple glazing in England?
In England, 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.
