How Much Do Bifolding Doors Cost? Bifold Doors Price Guide

What Are Bifolding Doors?

Bifolding doors, also known as bi-folding or bifold doors, consist of several panels that fold back on themselves, usually stacking neatly to one side. This design allows for a wide opening, making them a popular choice for both external and internal spaces. Unlike traditional sliding doors, bifolding doors can provide a completely open wall when fully retracted, offering more flexibility in how space is used. They usually have large panes of glass and frames made from various materials. uPVC and aluminium bifold doors are both popular.

These doors are typically installed to connect living rooms with gardens, patios, or balconies. They are most commonly used as external doors, but can also be used internally to divide larger rooms when needed. The key feature is their ability to create a large opening, which can be particularly useful for letting in light and air or for accommodating large gatherings.

Common Uses and Benefits

Bifolding doors serve practical purposes and fit various home designs. Here are some common uses and benefits:

  1. Natural Light: Large glass panels let in plenty of daylight, brightening up interiors and making spaces feel more open and inviting. This is especially useful in the UK, where natural light can be limited.
  2. Unobstructed Views: When fully opened, glass bifold doors offer clear views of outdoor areas.
  3. Versatility in Space Management: These doors allow homeowners to open up or close off spaces as needed. For example, they can make a room feel larger for social events or create separate areas for different activities.
  4. Improved Ventilation: Bifolding doors can be opened wide to let in fresh air, helping to ventilate the home and maintain a comfortable indoor climate.
  5. Variety of Styles: Available in materials like aluminium, wood, and uPVC, bifolding doors come in various designs to match different architectural styles, personal preferences, and prices.

Their price can vary based on several factors, which we will explore in this bifold patio doors cost guide.

Factors Influencing the Price of Bifolding Doors

Material Choices (uPVC, Wood, and Aluminium Bifold Doors)

The material of the bifolding doors significantly affects their cost. Each material offers different benefits and price points. Note – the price ranges in this guide are approximate prices only. Per metre figures should be multiplied by the width of your opening (in metres) to get the total price.


Aluminium bifold doors are popular due to their strength, durability, and slim profile, which allows for larger glass panels. They are low maintenance and resistant to corrosion. However, usually aluminium bifold doors cost slightly more. The price for aluminium bifolding doors typically ranges from £1,200 to £1,800 per metre.


uPVC bifolding doors are the most budget-friendly option. They are known for their good insulation properties and low maintenance needs. However, uPVC doors tend to have a bulkier frame, which may reduce the glass area compared to aluminium doors. Prices for uPVC bifolding doors range from £900 to £1,200 per metre.


Wood bifolding doors provide a traditional and warm aesthetic. They are often chosen for their natural look and can be customised with various finishes. Wood requires more maintenance than aluminium or uPVC, such as regular painting or staining to prevent weather damage. The cost of wooden bifolding doors generally ranges from £1,500 to £2,500 per metre.

Door Size and Configuration

Larger doors with more panels are more expensive due to the increased amount of materials and the complexity of the installation. For example, a standard three-panel bifolding door might cost around £3,000 to £4,500, while a five-panel door could cost between £5,000 and £7,500.

Double vs. Triple Glazed Bifolding Doors Cost

Glazing choices impact both the cost and performance of bifolding doors. Double glazing is the most common option, providing good insulation and soundproofing. Triple glazing, although more expensive, offers superior thermal efficiency and noise reduction. Double glazed bifold doors generally cost between £1,200 and £1,800 per metre, while triple-glazed options can range from £1,500 to £2,200 per metre.

Prices of Customisation Options (Colour, Finish, Handles)

Customisation allows homeowners to personalise their bifolding doors to match their home’s style, but it also affects the price. Options include:

  • Colour and Finish: Standard colours are usually included in the base price, but premium finishes or bespoke colours can add 10-20% to the total cost.
  • Handles and Hardware: Upgrading to high-end handles and locks can add between £50 to £200 per door.
  • Integral Blinds: Bifold doors with integral blinds cost an extra £500 to £1,000 per door on average, but are convenient and stylish.

Initial vs. Long-term Bifolding Doors Costs

Cost of Installing Bifold Doors

When considering bifolding doors, it’s essential to differentiate between the initial purchase price and the cost to install bifold doors. The purchase price depends on the factors previously discussed, such as material, size, and customisation options. For instance, a standard set of aluminium bifolding doors might cost between £3,600 and £7,200, while a similar set in uPVC could range from £2,700 to £4,800.

Installation costs are a separate consideration. Professional installation is recommended to ensure the doors are fitted correctly and operate smoothly. On average, the cost to install bifold doors can range from £600 to £1,500, depending on the complexity of the installation and any additional structural work required. DIY installation might save money upfront but can lead to issues if not done correctly, potentially increasing long-term expenses.

Maintenance and Upkeep Expenses

Long-term costs include maintenance and upkeep, which vary by material. Aluminium bifolding doors are low maintenance, typically requiring just occasional cleaning and lubrication of moving parts. Wood bifolding doors, while aesthetically pleasing, demand more frequent maintenance such as sanding, painting, or staining to protect against the elements. uPVC doors are also low maintenance, only needing regular cleaning to maintain their appearance.

Over time, the cost of maintaining wooden doors can add up, making them potentially more expensive in the long run compared to aluminium or uPVC options. Regular upkeep not only ensures the doors remain functional and visually appealing but also extends their lifespan, providing better value over time.

Energy Efficiency and Savings

Energy efficiency is another critical factor influencing long-term costs. Well-insulated bifolding doors, such as those with double or triple glazing, can significantly reduce heating bills by preventing heat loss during the colder months. This energy efficiency can result in substantial savings (and more comfortable summers) over the lifetime of the doors.

Triple-glazed bifolding doors, while more expensive initially, provide superior thermal insulation compared to double-glazed options. These doors help maintain a consistent indoor temperature, reducing the reliance on heating systems and thus lowering energy bills. Over time, the additional investment in triple glazing can be offset by the savings on energy costs.

Comparing Bifolding Doors to Other Door Types

Bifolding Doors vs. Sliding Doors

When comparing bifolding doors vs sliding doors, one of the key differences lies in how they open. Bifolding doors fold back on themselves and can create a completely open space, while sliding doors typically only allow half of the opening to be used at any given time.

In terms of cost, sliding doors can often be less expensive initially. A standard sliding door might range from £500 to £1,500, depending on the materials and size. In contrast, bifolding doors, due to their more complex mechanism and additional panels, generally start at around £2,700 for a basic uPVC set and can go up significantly for premium materials and larger sizes.

Functionality and use also differ. Bifolding doors are ideal for creating a wide opening, making them a popular choice for connecting indoor spaces with gardens or patios. Sliding doors, however, are sometimes preferred for areas with limited space since they don’t require additional room to open.

Maintenance and upkeep for both door types are relatively similar, depending on the materials used. Aluminium and uPVC options for both bifolding and sliding doors require minimal maintenance, while wood options need more frequent care.

Bifolding Doors vs. French Doors

French doors are another common alternative to bifolding doors. These doors are typically hinged and open outwards or inwards from the centre. They are often used in more traditional home designs and can add a classic look to any space.

Cost-wise, French doors can be more affordable than bifolding doors. Standard French doors usually cost between £600 and £1,200, making them a budget-friendly option compared to bifolding doors. However, French doors do not offer the same wide opening that bifolding doors provide, which can be a limitation for those looking to maximise the connection between indoor and outdoor areas.

The choice between French doors and bifolding doors often comes down to personal preference and the specific needs of the space. French doors are easier to install and can be more suitable for smaller openings, while bifolding doors are better for larger spaces where a more significant opening is desired.

Installation Costs for Bifolding Doors

Professional Installation vs. DIY

When it comes to installing bifolding doors, the choice between professional installation and a DIY approach can significantly impact the overall cost and the quality of the installation.

Professional Installation


Ensures that the doors are correctly aligned and operate smoothly. Professionals have the necessary tools and experience to handle any unexpected issues that may arise during installation.


Higher upfront cost compared to DIY. However, this investment can prevent future problems and additional costs related to improper installation.


Typically ranges from £600 to £1,500. Some door companies, such as Vision Glass Doors, offer free installation – make sure to consider this when comparing prices.

DIY Installation


Can be a more affordable option and a satisfying project for those with the necessary skills.


Risk of improper installation, which can lead to operational issues and additional costs for repairs. Lack of professional finish and potential voiding of manufacturer warranties if not installed by a certified professional.


Potentially lower as you save on labour costs. However, you’ll need to consider the cost of any additional tools or materials required.

Additional Costs for Structural Modifications

Installing bifolding doors might require structural changes to your home, particularly if replacing a solid wall or a different type of door. These modifications can add to the overall cost:

  • Wall Removal and Reinforcement: Removing part of a wall and adding necessary supports can cost between £1,000 and £3,000, depending on the complexity.
  • Electrical and Plumbing Adjustments: If there are electrical outlets, light switches, or plumbing in the area where the bifolding doors will be installed, you might need to relocate these. Costs can vary widely but expect to spend at least £200 to £500 for minor adjustments.
  • Permits and Inspections: Depending on local regulations, you may need permits for structural changes. Permit fees can range from £50 to £200. Additionally, inspections might be required to ensure the work meets building codes.

Tips for Reducing Installation Costs

  • Get Multiple Quotes: Shop around and get quotes from several installers. This can help you find competitive pricing and understand what is included in the installation cost.
  • Plan for Off-Season Installation: Some installers may offer discounts during off-peak times (late year) when demand is lower.
  • DIY Preparatory Work: If you’re comfortable, do some of the preparatory work yourself, such as removing old doors or clearing the area. This can reduce the labour required and thus the cost.
  • Combine Projects: If you have other home improvement projects planned, bundling them with the bifolding door installation might get you a better overall price.

Customisation and Its Impact on Cost

Made to Measure Bifolding Doors

One of the significant factors influencing the cost of bifolding doors is whether they are standard-sized or made to measure. Made to measure bifolding doors are customised to fit specific openings, which is particularly useful for non-standard or unusual dimensions. This customisation ensures a perfect fit, enhancing both the functionality and aesthetic appeal of the doors. However, the cost for bespoke bifold doors is generally higher. You can expect to pay an additional 20-30% over standard sizes, making the price range from £1,500 to £7,000 depending on the material and size.

Popular Customisation Features

Customisation options extend beyond just the size of the doors. Homeowners can choose from a variety of features to suit their preferences and needs. One such option is the choice of colour and finish. While standard colours might be included in the base price, opting for bespoke colours or premium finishes can increase the cost by 10-20%. For instance, powder-coated finishes in unique colours can add between £200 and £500 to the total cost.

Another popular customisation feature is the type of handles and hardware. High-end handles and locking mechanisms can enhance the security and appearance of the doors but also come at an extra cost. Upgrading to premium hardware can add £50 to £200 per door.

Additionally, bifolding doors with integral blinds are a sought-after feature for many homeowners. These blinds are sealed within the glass panes, offering a sleek look and easy maintenance. However, they are a premium addition, typically adding £500 to £1,000 per door to the overall cost.

Energy Efficiency Upgrades

Energy efficiency is a crucial consideration for many homeowners, particularly in the UK where energy costs can be high (the average heating bill for a 3-bedroom house in 2024 is £772 annually). Upgrading to triple glazing from double glazing is one way to improve the energy efficiency of bifolding doors. While double glazing is the standard and provides good insulation, triple glazing offers superior thermal performance. This upgrade can add £300 to £600 per metre to the overall cost but can result in significant energy savings (£10 to £30 per metre per year) over time.

Security Enhancements

Security is another area where customisation can impact the cost of bifolding doors. Enhanced security features such as multi-point locking systems, laminated glass, and reinforced frames can increase the initial price but provide peace of mind and potentially lower home insurance premiums. These security enhancements can add anywhere from £100 to £500 per door.

Frequently Asked Bifolding Doors Cost Questions

What's The Average Cost of Bifolding Doors in the UK?

One of the most common questions homeowners have is about the average cost of bifolding doors in the UK. The price can vary significantly depending on several factors, such as the material, size, and additional features. Generally, the average cost for a basic set of bifolding doors ranges from £1,400 to £6,000. For example, uPVC bifolding doors are usually at the lower end of the price spectrum, starting at around £1,200 for a standard three-panel set. Aluminium bifolding doors, known for their durability and sleek design, can range from £1,500 to £7,000. Timber bifold doors, offering a traditional and elegant look, typically cost between £2,000 and £8,000.

Are Inexpensive Bifold Doors Worth It?

Cheap bifold doors can be tempting, especially for those on a tight budget. However, it’s essential to consider what you might be sacrificing for a lower price. More affordable patio doors, often made from lower-quality materials like basic uPVC, may not offer the same durability, energy efficiency, or security as more expensive options. While they can be a cost-effective short-term solution, they might require more frequent maintenance or replacement, potentially leading to higher costs in the long run. It’s crucial to balance cost with quality, ensuring you get the best value for your investment.
