Triple glazing for new builds and self-builds in Caerphilly
Homes in Caerphilly can have new-build triple glazing supplied and fitted, with surveys arranged across Gwent including CF83.

Window and door packages priced from drawings and fitted to your programme. 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 Caerphilly

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
The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.
- Free survey and a written quote fixed for the specification
- Glass build-up and whole-window U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
