Rules for bifold 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.
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.

Questions from Bletchley
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.

Good systems lock at multiple points on each panel and use anti-snap cylinders. We specify tested doorsets where available.
Do I need permission for triple glazed bifold doors in Bletchley?
