Rules in England

In England, replacement windows must meet 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

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

Can my existing casement layout stay the same?

Yes. We match the existing layout unless you ask for a change, which can matter for planning in conservation areas.

Do casement windows need trickle vents?

If the old windows had them, yes, and at least as large. If not, ventilation must be no worse than before. We size this on survey.

What is an egress hinge?

A hinge that lets the sash open wide enough to climb out in a fire. It is used where a bedroom window is also the escape route.

Do you cover all of Essex?

We arrange surveys and fitting across Essex.

Do I need permission for triple glazed casement windows in England?

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.
