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.

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

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.

  • Free survey and a written quote fixed for the specification
  • Glass build-up and door U-value on every quote
  • Written handover pack at the end of the job
  • Guarantees on frames, units and fitting in writing

Questions

Are bifold doors secure?

Good systems lock at multiple points on each panel and use anti-snap cylinders. We specify tested doorsets where available.

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 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.

Do you cover all of Northumberland?

We arrange surveys and fitting across Northumberland.

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.
