Winter light and glass choice in New Malden

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

You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.

Questions from New Malden

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.

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.

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

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