Labour Cost to Install Bifold Doors
So, how much does the average bifold door installation cost in the UK?
The average labour cost to install bifold doors in the UK is typically around £600 to fit a 3-panel door system in one day. Larger bifold door systems with more panels may take longer to install and therefore cost more.
- 3-panel bifold doors: Around £600 labour for installation.
- 5-panel bifold doors: Around £1,000 labour if the installation takes around 2 days.
- Typical installation time: Most bifold door installations take 1 to 2 days.
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 may also need to hire a structural engineer to assess whether the wall where the doors will be installed is strong enough to support the opening. Structural engineers normally charge around £50 to £90 per hour.
The overall installation cost and time required will depend on the extent of the work. For example, if a new opening needs to be created or widened, the job may take an additional day and increase labour costs. Difficult access or working in confined spaces may also increase the price.
Additional Costs to Install Bifold Doors
There are additional costs you should keep in mind when getting a price for installing bifold doors:
- Structural work: If you require a new opening or need to widen it, a lintel beam may be necessary, along with some tidying up of the opening. This can have an impact on the labour cost and installation time.
- Removing existing doors: If you are replacing existing doors, you may need to budget for removal and waste disposal.
- Glazing upgrades: Double glazing is the common choice for external bifold doors. However, triple glazing can improve heat retention but costs more.
- Internal vs external doors: External bifold doors typically cost more than internal doors due to the need for weatherproofing, insulation, and security.
If you are unsure whether you will need structural changes, ask a tradesperson to inspect the opening before you order new doors.
Factors That Impact Bifold Door Installation Costs
Several factors can affect the total cost to install bifold doors. The main factors include the door material, the size of the opening, the number of panels, and the location of your property.
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 £1,350 to £3,240 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 £2,550 to £6,200.
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 modifications.
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 the 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.
This type of bifold door is commonly chosen by homeowners who want a more affordable installation. However, uPVC frames tend to be thicker than aluminium or timber, which can slightly reduce the glass area.
uPVC Bifold Doors: £1,950–£4,240 (Supply and Fit)
- Best for: Lower budgets, and homeowners who want low maintenance.
- Maintenance: Usually just cleaning the glass, tracks, and seals.
- Energy efficiency: Typically lower than timber and aluminium, depending on glazing and seals.
- Durability: Can warp over time and may weaken in harsh weather.
- Things to note: Wider frames can reduce glass area, and colour options are often more limited.
| 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.
Engineered timber is a robust and long-lasting material, which makes it a popular choice for bifold doors. Timber frames can also provide a natural appearance that suits traditional homes.
Timber Bifold Doors: £2,000–£4,200 (Supply and Fit)
- Best for: Traditional properties, or if you want a natural timber finish.
- Maintenance: Regular painting, staining, or varnishing.
- Energy efficiency: Typically better than uPVC, depending on glazing and frame quality.
- Durability: Long lasting when kept protected from moisture.
- Things to note: Engineered timber and hardwood usually cost more, but tend to last longer.
| 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 available. They typically feature a thermal break made from a less conductive material, which helps reduce heat transfer through the frame.
Because aluminium is strong, manufacturers can create slimmer frames with larger glass panels. This can allow more natural light into the property and is often preferred for modern homes.
Aluminium Bifold Doors: £3,150–£7,200 (Supply and Fit)
- Best for: Larger openings, modern homes, and slim sightlines.
- Maintenance: Low maintenance, usually just cleaning.
- Energy efficiency: Often good when a thermal break is used, and with quality seals and glazing.
- Durability: Strong and long lasting, with a robust finish.
- Things to note: Higher upfront cost than uPVC and many timber options.
| 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.
-
Checking the Structure
-
Preparing the Door Sill
-
Assembling the Frame
-
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.

Building Regulations & Planning Permission for Bifold Doors
If you are installing bifold doors in an existing opening, 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.

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.
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.
Benefits of Bifold Doors
Fitting bifold doors to a conservatory extension is a great way to enhance the asthetics of your property and offer a variety of benefits, whether they're open or closed, as outlined below:
- Seamlessly blends your indoor and outdoor living spaces, ideal for the summer months
- Opens your home to more natural light, even during the winter months
- Provides better ventilation, enhancing airflow throughout the home
- Maximizes usable space, making them ideal for smaller rooms
- Offers a larger entrance, making it easier to move furniture in and out of your home
- Improve energy efficiency, especially when upgrading to double or triple glazed doors
- Comes with upgraded security features for added peace of mind
- Can increase your property value with an attractive and functional design
By matching your bifold doors to the style of your property, from black aluminium for a modern look to wood for a more classic look, you are guaranteed to love this upgrade option.

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!
How Long Do Bifold Doors Last?
Most bifold doors can last between 20 and 30 years, depending on the material and how well they are maintained. Aluminium frames tend to last the longest, while timber doors may require more upkeep to protect them from moisture and weather damage.
