Triple glazed bifold doors in Portsmouth
If you live in Portsmouth (PO5) and want triple glazed bifold doors, start with a free survey: every opening measured, then a written quote that fixes the price.
Slim, strong bifolds rated for heavy triple glass. 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 Portsmouth
Winter days in Portsmouth are short: about 7 h 56 min of daylight on 21 December, with the sun peaking near 16°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

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.

Questions from Portsmouth
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.
