Bifold Doors FAQ
Everything you need to know about bifold door costs, materials, and installation in the UK.
In the UK, bifold doors typically cost between £400 and £900 per square metre for supply only. A standard 3-metre by 2.1-metre uPVC set costs around £1,500 to £2,500, while premium aluminium sets range from £3,000 to £5,000. Installation usually adds £300 to £500 per door pane.
Aluminium is generally considered superior to uPVC because it is stronger, allowing for much slimmer frames and larger glass panels. It also doesn’t warp or discolour over time. However, uPVC is significantly cheaper and offers better thermal insulation out of the box.
In most cases, no. Installing bifold doors at the rear or side of your property usually falls under ‘Permitted Development’ in the UK. However, if you live in a listed building, a conservation area, or a flat, you will likely need planning permission or building regulations approval.
A standard 3 to 4-pane bifold door installation typically takes 1 to 2 days. This includes removing the old doors or bricks, installing the structural support (lintel) if necessary, fitting the frame, and ensuring the doors run smoothly on the track.
The standard height for bifold doors in the UK is 2.1 metres. The width can vary greatly, but a typical 3-pane set is around 2.1 to 3.0 metres wide, while a 4-pane set can span 3.0 to 4.0 metres. Bespoke sizes are available but will increase the cost.
