Triple glazing for new builds and self-builds in Mitcham
If you live in Mitcham (CR4) and want new-build triple glazing, start with a free survey: every opening measured, then a written quote that fixes the price.
U-values, g-values and installation details for your assessor. 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 Mitcham
On the shortest day, Mitcham gets about 7 h 50 min of daylight and the midday sun reaches only about 15° above the horizon. Low winter sun means north-facing rooms here gain little solar heat, which is where triple glazing’s lower heat loss helps most.

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
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.
- 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
