Rules in England
England sets replacement door limits through Approved Document L (2021 edition, with 2023 amendments): 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
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
- 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
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.
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.
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.
Do you cover all of Essex?
We arrange surveys and fitting across Essex.
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.
