The cost of bifold doors and installation prices also vary based on the material used. The most common ones are uPVC, wood, and composite materials. Each comes with its own pros and cons and will ultimately influence the final cost of the bifold doors.

Price: £2,230 - £4,495 for 3 to 5-panel doors

uPVC is the most affordable material and, as a result, the most popular material used for windows in the UK. uPVC doors are widely recognised as the white plastic-looking material – common on newly built homes – but are available in a variety of styles and can even resemble timber woodgrain.

Price: £2,900 - £6,200 for 3 to 5-panel doors

Arguably, aluminium doors are the most modern and stylish option on the market. Even better, they don’t need much maintenance at all, and a wipe every now and then is enough to do the job.

Price: £3,345 - £6,745 for 3 to 5-panel doors

For the traditional look, timber doors are your best option. This is a naturally beautiful material that fits perfectly with period properties. With the right upkeep, wooden doors will last up to 50 years.

Price: £2,500 - £7,000 for 3 to 5-panel doors

Struggling to decide between aluminium and timber? Composite doors offer the best of both materials by bonding them together. Combining the benefits of these two materials makes composite a long-lasting, strong and durable material that has become ever more popular across the UK.

The number of panels that come with a door adds to the design complexity and materials used. When looking into bifold doors, you’ll notice they’re given 3 numbers that look something like a football formation, for example, 5-4-1. In this case, there are 5 panels in total, with 4 openings to the left and 1 to the right.

More complex door handles and locks can also add to the cost. Better locks can be important since bifold doors generally lead to the exterior of the home. Bifold doors are commonly seen in a single straight line along the back of the house, but it’s also possible to have them wrapped around a corner, which can add design complexity.

Similarly, since bifold doors often face the outdoors, they can be an area from which heat is lost. This can be mitigated by adding better types of glazing. Triple glazing can add 30% to 50% on top of the existing cost of the window, saving energy costs for exceptionally cold areas.

The colour and finish of the doors can add to the cost since the additional visual appeal of the door is worth the extra cost. Composite doors are easy to colour in and paint, providing a range of options for those who would want them.

Simpler bifold door installations can cost between £150 – £500 for a day of labour. Any installation that is more complicated and time-consuming will incur labour costs in the £500+ range. More complex installations might require creating a space in the wall for the doors, which will involve more work.
