Bifold door costs 2020: by material, location and size

The price of bifold doors varies depending on three main categories: material, location and size. Certain materials provide more protection but cost more. Bifold doors will have different requirements based on whether they are fitted externally or internally. And the size of a bifold door will obviously impact cost due to manufacturing.

External bifold doors

When discussing bifold doors, most people are referring to external bifold doors. It's essential to differentiate the location because they require different qualities from a bifold door.

External bifold doors are generally more expensive because they require additional qualities such as thermal efficiency, security and durability.

Average cost of bifold door

It is difficult to put an average price on bifold doors because of the huge amount of variety. The type of material, location and size all play a factor in pricing. Keep in mind that the average cost may not reflect the price you will be paying, especially if you are also paying for installation.

You can expect to pay between £1000 to £8000+ (supply only) depending on material and size.

Materials and size prices

External bifold doors are made from one of four types of material: aluminium, timber, composite or uPVC. Prices vary depending on the type of material.

Aluminium used to be considered one of the costliest materials but has since come down in price to match even the most reasonable bifolds. Wooden bifold doors are incredibly popular due to their good quality/aesthetic and good price. Composite offers the best of both worlds combining aluminium and timber offering excellent thermal properties and low maintenance. UPVC was known to have been one of the cheapest materials for bifold doors. However, recent findings have dictated that the average price of uPVC has increased (see below.)

Installation costs

The cost of installing a bifold door also varies by quite a wide margin. Your location, the size of the door, and the difficulty of the job will factor into the installation costs.

Vufold supplies doors which are self-assembly. Almost all the tools are provided—all you need to source is a screwdriver, drill, tape measure and spirit level. This level of ease means there is no need to hire a professional fitter, saving you time and money.

What affects installation costs?

  • Size –– the larger the bifold, the harder it will be to install and the longer it will take.
  • Location –– this includes whether the door is internal or external. It also includes where you live. For example, you should expect to pay more in London than in the northern regions.
  • Installation time –– bifold doors that are difficult to install will take longer to install. Most installers will charge daily rates.

Average installation costs

According to

The average price for a small bifold door (2.7m) is approximately £600 inc. VAT.

The average price for a large bifold door (4.7) is approximately £900 - £100 inc. VAT.

These are just average prices, you may find costs are higher or lower. Prices can vary depending on:

  • Additional works required to the building / opening,
  • Removal and disposal of existing doors
  • Installers experience
  • Location

Internal bifold doors

Internal bifold doors are generally cheaper than external bifolds. This is because they are usually smaller and don’t require the same levels of weather protection, security and thermal efficiency.

Almost all internal bifold doors are made from wood because they are lightweight, durable and aesthetically pleasing. Purchasing internal bifold doors made from aluminium or uPVC may be excessive as they will likely be double or tripled glazed, which will increase costs.

Average costs of internal bifold doors

Like external bifold doors, internal bifold prices can vary depending on manufacturer, material and location.

The average cost of a high-quality internal bifold can range from £700 - £2000

Installation costs for internal bifold doors

Internal bifold doors are generally less complicated to install due to less hardware required. This can make internal bifold doors cheaper to install than external.

The main factor in price is whether the internal bifold is being installed in an existing opening or not. With an existing opening, it's unlikely brickwork will be required so can be a relatively simple fit. If extra brickwork is needed, that can increase the cost by a considerable margin.

According to, to fit a standard internal bifold door into an existing opening, you can expect to pay approximately £250 for the labour and £650 for the material costs (if needed).

Can I install internal bifold doors by myself?

Standard bifold doors will likely require a professional for installation. This is because the installation process may be complicated due to how the doors are manufactured.  Instructions that are complex and difficult to read may require a professional to decipher.

However, high-end bifold doors like Vufold are ready-to-assemble meaning they are one of the simplest kinds of doors to install. If you have moderate DIY knowledge, you will be able to install Vufold bifold doors yourself. You can find example installation instructions on our website.
