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
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.
- Guide prices published, not hidden
- No pressure: the quote is yours to keep
- Frames, glass and fitting in one contract
- Advice on planning and consents before you order
Questions
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.
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.
Do you cover all of Cumbria?
We arrange surveys and fitting across Cumbria.
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.
