Winter light and glass choice in Grays

Rules for glass-only replacement 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.

  • 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 Grays

Will heavier glass damage my hinges?

It can. Triple units are about 50% heavier, so hinges and packers are checked and upgraded where needed.

Why are my windows misting between the panes?

The seal around the unit has failed and moist air has got in. Only replacing the unit fixes it.

Do you fit triple glazed replacement sealed units in Grays?

Yes. We arrange surveys and fitting in Grays and across Essex. Send your postcode and the windows or doors you want replaced, and we will book a free survey.

Do I need permission for triple glazed replacement sealed units in Grays?

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.
