Rules for flats and apartments 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.

Before ordering: 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 Chester-le-Street

Do I need permission to replace windows in my flat?

Often, yes. In England and Wales flats have no householder permitted development rights, so check with the council; in Scotland permission is generally needed only if the opening size changes or the flat is in a conservation area; in Northern Ireland ask your council. Separately, check your lease (England, Wales and Northern Ireland) or title deeds and factor (Scotland).

Is triple glazing good for a flat on a busy road?

Yes, especially with an acoustic laminated pane, which makes the bigger difference to noise.

Do I need permission for flat and apartment triple glazing in Chester-le-Street?

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.

How long does it take to get flat and apartment triple glazing fitted in Chester-le-Street?

After the survey, typical manufacture time is 4 to 7 weeks, and most homes are fitted in 1 to 4 days.
