Open the wall in summer, keep the warmth in winter. Bifold doors are made of several panels hinged together that fold and slide to one or both sides, opening almost the full width of the opening.

Winter light and glass choice in Tottenham

On the shortest day, Tottenham gets about 7 h 49 min of daylight and the midday sun reaches only about 15° above the horizon. Low winter sun means north-facing rooms here gain little solar heat, which is where triple glazing’s lower heat loss helps most.

Rules for bifold doors 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.

  • 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 from Tottenham

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 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.

Yes. We arrange surveys and fitting in Tottenham and across Greater London. Send your postcode and the windows or doors you want replaced, and we will book a free survey.

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

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. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
