Rules for sash windows 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

After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.

Questions from High Wycombe

Are uPVC sashes allowed in conservation areas?

It depends on the council and any Article 4 direction. Timber is often expected on front elevations. Check before ordering.

Can I keep my original sash boxes?

Sometimes. A timber specialist can fit new sashes into sound original boxes, but the glass thickness is limited by the sash depth.

How long does it take to get triple glazed sash windows fitted in High Wycombe?

After the survey, typical manufacture time is 6 to 10 weeks, and most homes are fitted in 1 to 4 days.

Do I need permission for triple glazed sash windows in High Wycombe?

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 or covered by an Article 4 direction before changing the style.
