Rules 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.

Before ordering: 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

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.

  • 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

Do I need building regulations for new bifolds?

Replacing an existing door is covered by the replacement rules. A new or widened opening is structural work that needs building control approval.

Are bifolds warmer with triple glazing?

Yes. The glass is most of the door area, so triple units cut heat loss and keep the inner surface warmer.

How much are triple glazed bifold doors?

Our guide starts at £4,295 fitted for a 3-panel aluminium bifold about 2.4 m wide and £6,295 for 5 panels, inc VAT.

Do you cover all of Somerset?

We arrange surveys and fitting across Somerset.

Do I need permission for triple glazed bifold doors in England?

In England, a replacement door on a house that looks similar is 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.
