Rules for whole-house replacement 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

We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.

  • Every opening measured, including escape and vent needs
  • Frames rated for the weight of triple glass
  • Old windows removed and taken away
  • Each opening closed up the same day

Questions from Islington

Do I need to move out?

No. We work room by room and make each opening weathertight the same day.

Will I need scaffolding?

Most two-storey homes can be done from ladders or towers. Where scaffolding is needed, it is quoted separately.

How long does it take to get whole-house triple glazing fitted in Islington?

After the survey, typical manufacture time is 4 to 8 weeks, and most homes are fitted in 1 to 4 days.

Do I need permission for whole-house triple glazing in Islington?

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.
