What affects the cost of bifold doors?
Number of panels & overall size
The biggest single factor. More panels and wider openings need more aluminium, glass and labour.
Door system
Premium Schüco and Cortizo systems with slimmer sightlines and better thermal performance cost more than entry-level systems.
Glazing specification
Double vs triple glazing, solar-control, acoustic or self-cleaning glass all change the price.
Colour & finish
Anthracite grey (RAL 7016) is standard; dual-colour, textured or non-standard RAL finishes add cost.
Threshold & structural work
Low/flush weathered thresholds and any structural opening work (lintels, steels) affect the total.
Supply only vs supply & fit
Supply-only is cheaper up front; supply & fit includes survey, installation and guarantee.
Frequently asked questions
How much do aluminium bifold doors cost in the UK?
As a guide, aluminium bifold doors cost from around £2,400 for a 2-panel set up to £9,600 for a large 7-panel set, supplied and fitted including VAT. Most 3 to 4 panel residential bifolds fall between £3,000 and £6,000. The final price depends on size, the door system, glazing and finish.
How much is a 3-panel bifold door?
A 3-panel aluminium bifold door (up to roughly 2.4m wide) typically costs between £3,000 and £4,800 supplied and installed including VAT, depending on the system, glazing and colour you choose.
Are aluminium bifold doors worth the money?
Yes — aluminium is stronger and slimmer than uPVC, allowing larger glass panels and more light, and modern thermally-broken systems like Schüco and Cortizo offer excellent insulation. Aluminium bifolds are low-maintenance and typically carry long guarantees, which is why they are the most popular choice for extensions and open-plan living.
Are bifold doors cheaper than sliding doors?
For similar sizes the cost is comparable. Bifold doors fold fully open so you lose almost no opening width, while sliding doors give larger uninterrupted glass panes. Price differences usually come down to the specific system, glass area and panel count rather than door type alone.
Do you offer supply-only bifold doors?
Yes. BDF Architectural offers both supply-only and full supply & fit options. Supply-only is more cost-effective if you have your own installer, while supply & fit includes a site survey, professional installation and our guarantee.
