Winter light and glass choice in Darlington

Rules for french doors in England

In England, replacement external doors must meet 1.4 W/m²K, or a door set energy rating of band C (more than 60% glazed) or band B (other doors). Replacement external doors fall under the same energy rules: a competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council, or a building control body approves it.

Planning: Replacing doors on a house is normally permitted development if the new ones look similar. Flats need planning permission for a change that alters their appearance, an Article 4 direction may mean permission is needed, and listed buildings need listed building consent.

How it works

The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.

  • 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
