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

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

Questions

For about 22 m² of windows and doors, our guide starts at £11,195 in uPVC and £18,895 in aluminium, fitted and zero-rated (new home).

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 Northamptonshire?

We arrange surveys and fitting across Northamptonshire.

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.
