Rules 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
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
- 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
Do you supply performance data for SAP?
Yes. Your energy assessor gets the U-values, g-values and frame data for the systems quoted.
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.
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 Mid Glamorgan?
We arrange surveys and fitting across Mid Glamorgan.
Do I need permission for new-build triple glazing in Wales?
In Wales, 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.
