Rules for flats and apartments in England

England requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. 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 from Feltham

What about tall blocks?

Higher-risk buildings (18 m or 7 storeys and over in England) have extra building safety requirements. Talk to your building’s accountable person first.

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).

How long does it take to get flat and apartment triple glazing fitted in Feltham?

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

Do I need permission for flat and apartment triple glazing in Feltham?

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.
