Winter light in Slough
Southern England has the UK’s highest winter sun angles, about 15° at midday in Slough in late December. Big south-facing windows here can make good use of a higher solar-gain triple unit.
Rules in England
The rules for replacement windows in England are set by Approved Document L (2021 edition, with 2023 amendments): 1.4 W/m²K, or a Window Energy Rating of band B or better. Replacement windows are a controlled fitting. A competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council within 30 days; otherwise a building control body approves it.
Planning: Replacing windows on a house is normally permitted development if the new ones look similar. New upper-floor windows in a side wall must be obscure glazed and fixed, or open only above 1.7 m. Flats and maisonettes have no householder permitted development rights, so a change that alters their appearance needs planning permission. An Article 4 direction in a conservation area may mean permission is needed, and listed buildings need listed building consent.
How it works

Questions
Are there grants for triple glazing in England?
Rarely. Most schemes fund insulation and heating before glazing. See our regulations and funding guide for the current position.
Do I need planning permission in Slough?
In England, like-for-like replacements on a house are normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent. Check whether your street is in a conservation area before changing the style.
How long does fitting take in Slough?
Most homes are fitted in 1 to 4 days once the windows are made; manufacture takes about 4 to 12 weeks depending on the frame.

Our guide prices are the same UK-wide: triple glazed uPVC windows from £695 each and a 3-bed semi from £9,395, fitted and inc VAT.
