Our timber bifold doors offer a warm, classic look with modern functionality — ideal for traditional homes or anyone seeking a natural finish.

However, with so much choice comes some indecision. It is hard to know which bi fold doors are worth using or who you should trust to install them.

As a homeowner in April 2025, letting a third party work on your home can be tough, especially if you do not know who can give you the best results.

We offer a range of bi fold doors and full installation and maintenance options to ensure that your new natural light does not come with unexpected costs.

Our bifold door systems are chosen for beauty and convenience, fitted to each customer’s home as a bespoke project.

How Much are Bi Fold Doors?

Standard aluminium bi fold doors can cost anywhere from £2,000 to £6,000, with the total price varying based on several factors.

Of course, these are just averages – we try to keep our work affordable in every situation.

Some features may come with an extra cost, but the main advantages make up for it. For example, bi fold doors cost more if they are double glazed, but they also retain heat better, saving you money on energy and keeping you warm in the cooler months.

Our sales team always try to get accurate numbers on the bi-folds we produce, so you can talk to us for more specific breakdowns of your expected costs. The total cost can be affected by factors like:

Materials

The materials we use for each of our bifold doors will dramatically change the total cost. For example, wooden bifold doors are often cheaper than aluminium ones with double glazing, but a more expensive one often comes with benefits that cheaper door types would not have.

Composite bifold doors and UPVC bifold doors can be even cheaper but are often meant to be used in highly specific ways and lack the added strength of aluminium bifold doors.

If you are unsure what to choose, talk to our expert staff to get a breakdown of what we can offer and which materials best suit your needs.

Size

The larger your new exterior bifold doors, the more they cost. Adding an extra third of a meter to aluminium bifold doors can bump the price by at least £100 or more on average.

A larger size means more material, more time spent installing the bifold doors, and more maintenance work needing to be done. However, we aim to keep our prices cheaper than average where possible.

Colour

Colour can sometimes influence the cost of bifold doors, especially if that colour means a specially-painted design.

We can create bespoke bifold doors that suit your needs perfectly, but bespoke changes like unique colour palettes may require extra time and effort.

Design

A bespoke design for external bifold doors takes more time and effort than simply installing some pre-prepared bifold doors.

However, we are more than willing to take on one-of-a-kind projects that leave you with unique, entirely bespoke bifold door designs that suit your specifications perfectly.

Aluminium Bifold Doors

Our aluminium bifold doors are some of the most popular we create, especially as exterior bifold doors.
