What Are Bifold Doors?
Typically, bifold doors have 2 or more standard-size glass doors that are connected and opened as a concertina, which can then fold flat. This allows for them to fully open up — whereas a sliding door is often a cheaper alternative, but is limited in how far they can open.
Bifold doors also help create a seamless living space, connecting the interior of your property with a terrace or patio while providing extra natural light indoors.
They have also become more popular in recent years, due to being relatively easy to install, which can help keep labour costs to a minimum, while remaining easy to operate and with relatively minimal maintenance required depending on the material.
In this guide, we go through everything you need to know about the cost of bifold door installations in 2025. This includes prices for different sizes and types of bifold door (uPVC, aluminium, timber) and what you should expect tradespeople to charge.
How Much Do Bifold Doors Cost to Install?
In 2025, most standard bifold installations cost around £3,000. However, the cost of bifold doors and installation ranges between £1,950 to £7,200.
Prices you're quoted by tradespeople will depend on a variety of factors, including the door frame material and how many doors you want to have installed.
Timber bifold doors tend to cost from £2,000 for 3 door system and up to £4,200 for 5 doors, while uPVC bifold doors range from £1,950 for 3 doors and £3,240 for 5 doors.
Aluminium bifold doors are slightly more expensive and are normally priced at around £3,150 for 3 doors and up to £7,200 for a 5-door system.
What else can affect the overall cost for bifold doors?
The dimensions of the doors matter, as the larger the width and height, the more you will pay. The location of the property may also determine the final cost, as tradespeople in London and the South of England may charge more than those in northern areas.

Labour Cost to Install Bifold Doors
So, how much does the average bifold door installation cost in the UK?
The average labour cost for installing bifold doors is normally around £600 to fit 3 door panels in one day, while a 5-door system may take around 2 days to complete and typically costs around £1,000.
This would normally cover the cost of two tradespeople to complete the job, as it speeds up the installation.
I’m looking at having bifold doors installed on the patio and have a price for supply only, but I would like a price for installation, please.
"Usually around £700, but it would depend on the size and location."
You also want to consider hiring a structural engineer to assess whether the wall where the doors will be installed is secure enough to hold them. They normally charge around £50 to £90 per hour.
What do labour costs and duration of installation depend on?
The overall cost to install bifold doors, as well as how long it takes, will vary depending on the extent of the job.
For example, if a new opening needs to be made, then this may add on another day and increase the price. The price will also be dependent on the level of access, as tradesmen may charge more for a difficult job.
Factors That Impact Bifold Door Installation Costs
Before investing in bifold door installation, you need to consider the following cost factors that will affect the final price:
Bifold Type
One of the most important elements you need to consider when having new bifold doors installed is the type of bifold you want.
There are three main types – timber, aluminium and uPVC – which all have different qualities and vary in price.
If you have a low budget in mind, you may want to opt for uPVC with supply prices ranging from £1350 to £3240 and timber bifold doors, which cost around £1400 to £3200. For a long-lasting and robust installation, you may want to consider aluminium bifold doors, which are normally priced at £2550 to £6200.
Door Size
Another important cost-affecting factor is the door size, as there are multiple options available that fit different budgets.
For example, smaller sizes such as 1.79m to 2.4m range from £1350 to £2200, while medium-sized bifold doors between 2.7m and 3.5m cost around £2240 to £4070. For larger door panes, which range from 3.6m to 5m, you should expect to pay around £2680 to £6200.
Property Location
Where you live is also a contributing factor to the overall installation price, as the rates set by tradesmen will vary depending on the location.
For instance, joiners in London tend to charge around a minimum of £36 per hour, while tradespeople in northern areas normally have a set rate of around £20 per hour.
Accessibility
Another important aspect that will affect the cost is the level of access to the area where the doors will be installed. If this area is hard to reach due to a wall being in the way or uneven ground, then you may end up paying for additional modifcations.
Choosing Bifold Doors
To help you choose the right bifold doors for your home, here is a breakdown of the different types of bifold doors, along with the costs and pros and cons of each.
uPVC Bifold Door Cost
uPVC bifold doors are a low-budget option which cost around £1950 to £4240 to install. uPVC stands for unplasticised polyvinyl chloride, which is a type of hard and resistant plastic.
Some of the advantages of opting for uPVC bifold doors is that they are one of the cheapest options available and are also very low-maintenance.
This bifold door material has the highest U-value rating of 1.7W per m2, which means it is the least efficient of all. It is also prone to warping and is susceptible to weakening during adverse weather conditions.
| No. of Doors | Supply Only Cost | Total Cost |
|---|---|---|
| 3 (1.79m – 2.4m) | £1,350 – £2,200 | £1,950 – £2,800 |
| 4 (3m – 3.5m) | £1,990 – £2,700 | £2,790 – £3,500 |
| 5 (3.6m – 4m) | £2,560 – £3,240 | £3,560 – £4,240 |

Timber Bifold Door Cost
Timber bifold doors can be made up of various types of wood including solid timber, hardwood and engineered wood although the latter is the most popular option.
This material is one of the robust options available, especially if the bifold doors are built using engineered wood which is also long-lasting. It is also an average U-value rating of 1.4W per m2, making it more efficient than uPVC doors.
Cheaper timber doors do not last well exposed to the UK weather, whereas the engineered timbers and hardwood products are more durable but also pretty expensive. Though timber does offer that traditional appearance and natural beauty of wood, the downside is timber bifold doors will require regular painting or varnishing over the years.
| No. of Doors | Supply Only Cost | Total Cost |
|---|---|---|
| 3 (1.8m – 2.4m) | £1,400 – £2,200 | £2,000 – £2,800 |
| 4 (2.7m – 3m) | £2,240 – £2,630 | £3,040 – £3,430 |
| 5 (3.6m – 4m) | £2,680 – £3,200 | £3,680 – £4,200 |

Aluminium Bifold Door Cost
Aluminium bifold doors are one of the most durable options, which typically feature a thermal break made of a less conductive material which helps to reduce thermal conductivity.
Aluminium has the most efficient U-value rating of all bifold door materials at just 1.3W per m2. It is also a much stronger material so can offer much slimmer profiles. In addition, the powder-coated finish requires virtually no maintenance, so there is no need to varnish or paint every few years.
Aluminium bifold door panels can also be made wider than timber doors, so you can sometimes need fewer doors within the same frame size, which saves money.
The downside of choosing aluminium bifold doors is that they are costly, so they may not be the best option if you have a tight budget. Aluminium is also known as a poor thermal conductor, which means it may be susceptible to heat loss if no thermal break is installed.
Cost of Aluminium Bifold Door
| No. of Doors | Supply Only Cost | Total Cost |
|---|---|---|
| 3 (2.1m – 3.5m) | £2,550 – £4,070 | £3,150 – £4,670 |
| 4 (3.6m – 4m) | £3,500 – £4,900 | £4,300 – £5,700 |
| 5 (4.2m – 5m) | £4,260 – £6,200 | £5,260 – £7,200 |

What options, other than a roof lantern or skylights, do I have to make my kitchen extension really light and airy?
"A good idea to make an extension or any space light and airy is to introduce a set of bifold doors from finish floor level to ceiling. Expanding the width of the extension when open gives you a great visual of your garden space, leaving the interior feeling part of that."
What's Involved in Installing a Bifold Door?
To help you understand the process of hiring a professional tradesman to install bifold doors, here is a step-by-step breakdown of what the job entails.
-

-
Preparing the Door Sill

-
Joining the Sill and Frame
-
Fixing the Frame
-
Installing the Packing
-
Attaching the Sill and Head

Mounting the Bifold Doors
Before the doors can be installed, a structural engineer will check that the wall is able to support the new installation. This usually involves drawing up plans and installing a lintel beam for horizontal support.
Once the structure has been deemed sound, then the door sill can then be attached. If yours does not come pre-assembled, then the tradesman will use silicone to attach the parts followed by drilling pilot holes in the fixing holes on the underside of the sill to secure it.
After the sill has been assembled, the door installer will then start to fit the frame, which will normally be attached using woodscrews and gaskets along with silicone sealant, which should be applied to each end of the head assembly, the tenon and jamb assembly.
The next step involves attaching the head and jamb assembly together followed by screwing it to the sill. They will then check that all the frames are square and even before tightening any loose screws.
Once everything has been assembled, the door installer will then fit the frame onto the wall opening while making sure the head track fixing holes are in the correct position. If everything is right, they will then pre-drill the lintel, followed by removing the head frame and pre-drilling any masonry above the lintel.
After the positioning has been checked, they will then install around 5mm of packing around the head and top of the opening and the bottom of the sill. The tradesman will then use a spirit level to check everything is in line before securing the packers by drilling into the prepared holes and attaching frame fixing bolts.
The next step involves establishing a fixing point and drilling for a masonry plug in order to attach the sill ties. The head should then be installed by screwing in the outer fixings first before lightly tightening the screws to a point where the lintel and head are almost touching.
To ensure your bifold doors open properly, the installer will fit the carrier hinges and pivots onto the top track making sure that the adjustment screws are accessible at the bottom of the doors.
Before installing the doors, the tradesman will check all the other fixtures and fix anything they need to. Once they are happy that everything is in the right place, they will mount the doors onto the frame and hinges.
Do frameless bifold doors have any extra requirements than normal bifolds? And how energy efficient and weatherproof are they?
"No, the energy efficiency comes mainly from the glass not the frame. Although, the frames will have a foam insert to help reduce heat loss.
They're waterproof, but I wouldn't use them, for example, on a coastal property in direct wind. All systems are tested and need to meet minimum requirements.

Bifold Door Alternatives
If you feel as though bifold doors are not the best option for you, then are various other patio door types to choose from, including:
Sliding Doors Cost
Sliding patio doors are categorised by the horizontal sliding function, with some featuring a disappearing effect behind a wall when slid open. The average cost of sliding patio doors is normally around £500 to £1,500.
The main advantage of sliding doors is that they offer the best views due to the amount of glass on show. The increased glass also makes it much more efficient as it enhances thermal efficiency.
Sliding doors can be hard to install and usually require specialist equipment if fitted on the first floor or above. Also, if installed in an existing opening, they will not open completely.
French Doors Cost
French doors offer a traditional style door system which opens outwards on a hinge. The average cost of french door installation is between £900 to £1,925.
One of the benefits of choosing French doors is that they can be customised to suit both traditional and contemporary properties. They also help to boost kerb appeal as they tend to make homes look bigger and also increase natural light.
A downside of opting for French doors is that they require a significant amount of space for the doors to open, so if you have limited room outside, then French doors may not be the best option. They also have poor energy efficiency ratings and are also prone to leakage as the seal is not as robust as that of bifold doors.
Building Regulations & Planning Permission for Bifold Doors
If you are installing bifold doors in an existing open, then typically you do not need to apply for planning permission or building regulations approval.
However, if you need a brand new opening or plan to widen the opening to accommodate your bifold doors, you may need to submit a planning permission application, although this will depend on your local authority's regulations.
Do bifold doors require planning permission? When would they and when might they not need approval? Does it depend on their size, etc?
"If the bi-fold doors are replacing an original door, then no permission is required. If you are to knock down a wall to put in a bifold door then a structural survey would be required before works."
An application will also be required if you live in a listed building or conservation area, which should cost around £200.
If you are creating a new opening for your bifold door installation, you will need to ensure that the structure where they are being fitted is secure.
You should also make sure that the lintel used is at least 150mm at each end with a minimum opening width of 300mm.

Cost of Bifold Doors Removal
If you wish to replace your old bifold doors with a brand new model, then you will need to have your existing doors removed. To hire a professional to remove your bifold doors, you should expect to pay around £160 to £220 per day.
If you plan to remove them yourself, you will have to consider the cost of waste disposal, which typically ranges from £70 to £120.

FAQs
Can I install a bifold door myself?
Bifold doors are not a typical DIY project as they are far more complex than traditional sliding doors, and require some careful planning and calculations, which may also result in additional structural support being required. In some cases, the wall can be prepared by a professional builder, although the door should still be fitted by a professional to avoid any potential damage and incorrect installation.
How are bifold doors supported?
Bifold doors are supported by a strong lintel beam that is able to hold the weight of the doors. To ensure you choose the right size lintel beam, you should consult with a structural engineer who will determine which lintel is best.
Can bifold doors be used on a first floor?
Yes, but there are extra factors to consider that may affect the overall cost. If the property isn’t already suitable, then structural work may be needed. For safety reasons, the doors should ideally open onto a balcony area. If an outdoor area isn't possible, a Juliet balcony is a practical alternative.
Will bifold doors increase my heating costs?
Modern bifold doors are designed with having good insulation in mind, therefore, if you’re replacing old doors or windows, they can actually make your home more energy-efficient which may help lower your bills instead.
What maintenance do bifold doors require?
While generally considered as low-maintenance, it's important to periodically wash the windows and clean the tracks to help keep the hinges well-lubricated. It's also advisable to check the seals a couple of times a year, ensuring they are secure and waterproof. As for timber doors, they should be repainted and restained every 2-5 years and regularly inspected for unwanted rot or moisture damage.
Do I have to slide all the panels in a bifold door to open it?
No. A traffic door is available, which allows you to use just one door without moving any other panels. A traffic door is a worthwhile option in the UK as it allows you access in and out, without letting in the cold air!
