How Much to Fit Patio Doors in the UK?

Patio doors are one of the most popular features to have installed in the UK when it comes to renovating the back of your home. They provide easy access, while also allowing natural light and garden views into the room, plus the likes of reinforced or laminated glass help add another layer of security to your property.

The type of patio doors you could use is determined by the size of the potential opening, your design preferences, and, of course, your budget.

Each type of door has its own set of advantages, and a patio door can be any door that opens onto a patio or garden space, such as the popular sliding doors, bi-folding and French doors.

There is a lot to consider when installing patio doors, including the cost, but you also must think about choosing a tradesperson and dealing with potential planning permission and building regulations.

This section will go over everything you need to know about patio door costs.

So, what are the average patio door installation costs?

In the UK, sliding uPVC patio doors start at around £600 for supply only, or £850 for supply and installation. However, the French style in white uPVC patio doors start at around £390 supply only and £750 when installed.

All of those are, of course, estimates based on patio door installation prices in a variety of sizes and styles. Prices will vary depending on the size, material, and other factors.

How Much Are Patio Doors?

The average cost of materials for installing patio doors will eventually impact the quality of patio doors you want to install, how many you want to install, and whether it is double or triple glazed.

Extra material costs, such as plastering materials or paint, may be incurred to tidy the outer edge of the new patio doors.

French Patio Door Cost

French doors are the most common option for patio doors, ranging from £500 to £1,500. They are best suited to smaller spaces and doorways because they open outwards, and they are ideal for single-door access and double-door opening on a warm day.

They are most used in conjunction with uPVC material, but aluminium can also be used for a higher price while using less material and more glass within the design.

Sliding Patio Door Cost

Sliding patio doors are ideal for small and restricted spaces such as courtyards or modest patio gardens, and their prices range from £500 to £1,500. They provide several advantages, including a smooth operation to create a wide opening that helps create a seamless transition from home to garden and eaasy access to outdoor areas.

Aluminium is a popular material because it enables larger sizes with much more glass and far less material.

Bi-fold Patio Door Cost

Bifold patio doors cost between £1,000 – £4,000 and offer a fully opening operation, making them ideal for large buildings.

Bi-folding patio doors are a luxurious option with various design options and are suitable for door openings larger than 2500mm. Aluminium, uPVC, and natural wood can be used to create a visually appealing barrier between indoor and outdoor spaces.

Additional Patio Door Installation Costs

When installing patio doors, take advantage of the opportunity to inspect other areas that may require repair or updating.

While some of these areas may not be essential at present, it's worth future-proofing your home to cut down on costs later.

Triple Glazed Window Cost

Instead of the more traditional two panes, triple glazing uses three glass panels within a sealed frame. Small gaps between the three panes are full of air or gas like Argon.

Even though glass conducts heat reasonably well, double and triple-glazed windows transfer heat by using layers of air/gas between the panes, making it harder for heat to escape.

Triple glazing window costs are higher, but it provides better heat insulation — so it is most common in Scandinavian countries or other cold-weather regions.

The cost of supplying and installing triple glazing in a typical two-bedroom flat with four windows ranges between £1,970 – £2,000.

The cost of supplying and installing triple glazing in a typical two-bedroom flat with four windows ranges between £4,000 – £4,200.

The cost of supplying and installing triple glazing in a typical two-bedroom flat with four windows ranges between £5,700 – £6,000. The supply and installation of triple glazing for a four-bedroom detached house with 15 windows will cost around £7,000.

Patio Laying Cost

The average cost of laying a patio in a 20m² area ranges between £900 – £2,500. This price includes excavating the area, laying the foundations, purchasing, and laying the patio slabs.

These prices will vary depending on the materials used. For example, budget options like concrete and brick patio slabs start at £15 per square metre, whereas premium patios are usually made of slate, which varies from £900 to £3,800 for installation, and a stone patio can cost up to £4,600.

House Painting Cost

The average cost of painting a house that has three bedrooms and is two storeys high is around £850.

However, keep in mind that this is only an estimate, and many factors will affect the final cost of your project.

These elements include the size of your home, its design, the materials used, and the tradesperson's hourly and daily rates.

Outdoor Lighting Cost

The average cost of installing outdoor lighting varies according to the type of lighting you choose. Floodlights, for example, can be installed for around £80 - £180, and motion lights can be installed for around £90 - £500.

Some more expensive alternatives, such as landscape lighting, can cost more than £1,000.

The type of lights installed, the number of lights needed, the location of your asset, and the labour cost of installing outdoor lights are all factors that can affect the overall cost.

House Rendering Cost

Depending on the size, difficulty, and methods used, the cost of rendering a house can range between £2,000 – £8,000.

A small bungalow, for example, will cost significantly less than rendering a large, detached property. Another factor to consider is the type of rendering processes and equipment used, as these can significantly reduce or raise the total cost of the job.

It might be possible to render your house yourself, but if you are uncertain of your skills or don't have any experience with this type of work, hiring a qualified tradesman may be a wiser course of action.

Patio Door Installers Cost & Timescales

The average patio door installers cost is between £150 – £200 per day.

Because some heavy lifting is required, patio door fitters typically work in pairs, and they may subcontract work if they cannot complete the job themselves due to structural or plastering issues.

If you are modifying or creating an opening for patio doors, a load-bearing lintel may be required. When comparing quotes from professional builders, make certain that this extra work is included.

In some cases, a structural engineer could be required — expect an increased expense of around £100 if that's the case.

The time required to install patio doors in your home will vary depending on the type.

For example, sliding patio doors and French doors can both be installed within 4 to 6 hours, and bi-folding patio doors can typically be completed within the same day. However, complex installations such as the need to remove walls or add support beams can take much longer.

Several factors may influence patio door installation time, including the ease of access to your garden, the condition of your garden area, the difficulty of the particular patio door product chosen, and whether or not the previous patio doors must be removed first.

Factors That Impact Patio Doors Installation Costs

Fitting a patio door may appear to be a simple task, but there are many factors to consider when planning and implementing that can affect the price of patio doors, including what door to use, where and how to fit it, the type of material, and how to dispose of any waste.

All these factors can add up to high costs without your knowledge, so it's critical to consider all potential costs when estimating the cost of patio door installation.

Size of the Patio Door

The price of the door unit is determined by the size of the door you intend to install in the opening, with sliding and French doors requiring more panels to fill a larger opening. This means that there will be additional tasks to complete that will increase the installation costs.

For example, modern house designs include standard-sized window and door openings, but older properties do not. If this is the case, you will have to cover the difference with additional fixed panels on both the side and top.

Patio Door Material

The unit's material has a significant impact on the price. Softwood doors are currently the cheapest, but they're also more prone to weathering issues.

uPVC is less expensive than aluminium. However, because aluminium has a longer life, you won't have to replace it as frequently as uPVC. In addition, both aluminium and uPVC can withstand inclement weather and do not absorb water, swelling, or rot like wooden doors.

Engineer in Structural Design

If you intend to replace the lintel with one with a longer span, have the dimensions calculated by an expert. Occasionally, a patio door business will handle this for you. In any case, you'll pay around £100 for their services.

Patio Door Features

This represents the patio door handles, latches, locks, and other attachments. Most manufacturers offer a selection of door decor based on your budget and the overall effect you want to achieve, so you should be able to find a combination that suits you.

Waste Disposal

Waste removal can range from £100 - £200 depending on the amount required to fill a skip for skip hire. This will be included in the price if you hire a tradesperson.

Patio Door Finish

Standard uPVC units are made of plain white plastic but the options don't stop there.

Both uPVC and aluminium doors come in a variety of colours and finishes. However, other finishes, including woodgrain and different colours, are also available.

uPVC can be made from coloured vinyl that has been sprayed with a suitable paint covering. Alternatively, use coloured or patterned foil (a type of laminate). At least 15 different coatings are available for uPVC units, such as woodgrain foils.

In contrast, aluminium uses powdered plastic melted onto the plain metal surface using a heat bonding technique. This is virtually impervious to weathering. And there are probably hundreds of textures and colours to choose from when using this method.

Window Energy Efficiency (WER) Rating

All new patio doors (to calculate WER, they will be treated as windows) must meet the energy performance standards outlined in the UK Building Regulations. All glass companies manufacture glass that meets the standards required to manufacture an energy-efficient window.

On the other hand, the Window Energy Rating applies to the entire window or patio door. As a result, the frame's performance is also included. Windows with ratings such as A++ are more expensive than those with ratings such as C.

Location

The type of patio doors you select will be determined by the space available in the specified location. For instance, if you have a small patio or even want doors from a bedroom to a balcony, an open French door set will take up too much space. In these cases, a sliding door is the best option.

You must also consider the location of the patio door in the house. Patio doors, such as French doors, are prone to be blown shut by strong winds. Furthermore, they typically open outwards, exposing the inside surface to brain damage if left open during a storm.

What's Involved in Installing Patio Doors?

When creating a new entrance for your patio doors, a load-bearing lintel may be required as support. When requesting costs, make sure this work is included in the quote, as an architect or structural engineer may need to assess the need for a lintel or additional structural work.

With MyJobQuote, you can arrange visits from local patio door installers in your area. This is a free service and with no obligation to go ahead with the work. It's also widely recommended to request multiple quotes, in order to compare prices and expectations.

Although doing it yourself will potentially save you money, even a relatively straightforward installation can cause issues. If you don't seek professional advice, failure to include the proper support could also result in structural damage and lead to further expense at a later date.

Below we take a look at the process, under the assumption no additional building work is required:

Before the Job Starts

• Removing the Old Door — If an old patio door is in place, the contractor will remove it before starting on the framework for the replacement.

During the Job

• Framework Installation — The framework will be installed, using a bubble level and washers for accurate placement. The frame will be mounted with seals and adjusted to fit the wall reveal.
• Mounting the Frame — The frame for the door is securely screwed into the wall to ensure structural strength. Using an impact drill, the tradesperson will drill holes into the masonry and then use a cordless electric screwdriver to fasten the frame in place.
• Sealing Gaps — Once the frame is attached, any gaps between the frame and the wall will be filled with insulating material. Interior sealing is done with foil, and exterior sealing uses sealing tape, which must expand fully before foaming begins.
• Installing the Leaf — The procedure concludes with inserting the leaf, which is the door itself. Providing everything is lined up correctly, the leaf will be attached to the hinges by your tradesperson.

After the Job

• Final Adjustments — The door's functionality will be tested multiple times, including the locks. If the door jams or squeaks, the leaf may need to be re-adjusted to ensure smooth operation and proper installation.
• Waste Removal — Before starting the job, you should confirm that waste removal is included as part of the quote. Assuming it is, any fixtures and fittings from the old door will be disposed of, along with any remaining debris if there has been any structural work.

When Should Patio Doors Be Replaced?

The decision to replace patio doors may be based on the age of the existing doors. The type of material they're made from indicates how long you can expect your patio doors to last:

These are only estimates, with the longevity of any patio door depending on numerous factors.

If you notice any of the following issues, you may want to consider patio door replacement:

Poor Functionality

Patio doors that have become difficult to use may need to be replaced before the problems get worse.

Examples of signs that it's time to replace your patio doors include:

• Difficulty opening or closing the door smoothly.
• Inability to close the door completely.
• Problems locking or unlocking the door.
• Presence of noticeable draughts.
• Moisture and fog build up on the glass.
• The doors and frames aren't lining up correctly.
• Misalignment or the door coming off the tracks.

Some of these issues could be dealt with through repairs rather than a full patio door replacement, but they will often be uneconomical to repair and it may be cheaper to get a straightforward replacement.

Problems with the Glass

Misty glass on your patio door could indicate a leak in the seal around the glass itself. This reduces the effectiveness of the door as a whole, plus it could turn into a security risk if the glass is weakened.

You should also watch out for cracks and chips in the glass. These could get worse quickly and shatter suddenly, meaning urgent and more costly work will be needed rather than a planned patio door replacement.

Poor Energy Efficiency

Modern patio doors are far more energy efficient than their older counterparts, so you may notice that you're losing a lot of heat through the door if you have an ageing one.

Making changes such as replacing a patio door can add up to greater savings on energy bills in the years ahead.

Improve the Visual Appeal

One final reason to contemplate a new patio door installation is because your home's style has changed.

A home renovation or garden landscaping project could make the patio door stand out in a negative way, so replacing the door as part of a wider job may make sense.

It could also be that a patio door is simply showing its age and doesn't look great anymore. If minor aesthetic changes and repairs don't help, it might be time to opt for a replacement.

Building Regulations & Planning Permission for Patio Door Installation

Installing a patio door doesn’t usually require planning permission, especially if it’s a like-for-like replacement. However, if you're altering the structure of the property or making the opening bigger, you may need approval.

Listed buildings or homes in conservation areas often have stricter rules, so in these instances it’s always best to check with your local council regardless before arranging any work.

As for building regulations, there are certain standards that need to be met when installing patio doors in the UK - these largely involve around safety requirements and energy efficiency standards. This will include the likes of safety glass, providing the room with sufficient ventillation and fire precautions.

It's always recommended to use a registered contractor, such as those part of FENSA or CERTASS, as they can sign off any building regulation certification without the need of involvement from the local council. However, if you do hire an unregistered tradesperson, you’ll need to request an inspection from the local authorities.

Types of Patio Doors

When it comes to patio doors, you have complete freedom for new construction, but if you are just having new patio doors installed, your options may be limited because you must match the rest of the exterior windows.

We will go over the various types of patio doors and their benefits and drawbacks.

Sliding Patio Doors

For many years, sliding patio doors have been a prominent choice of English homes. They provide unrivalled views of the garden through large glass panes, which are almost entirely unbroken by their frames.

While a large enough wall is required to adjust two large panels, the spatial requirements for sliding patio doors are modest. They don't require any space to open inwards or outwards, so they can be used in small patio areas or rooms with a lot of furniture.

Modern patio doors are made of uPVC plastic. This is a sturdy, lightweight material that comes in various colours and can be customised to meet the needs of individual customers. Sliding doors were once known for their lack of security due to poorly constructed locking mechanisms.

Pros

• ✔ Allow easy access to your patio and garden.
• ✔ Improve your energy efficiency.
• ✔ Provide a high level of protection.
• ✔ Sliding patio doors can be installed to make them accessible to everyone, including those in wheelchairs.

Cons

• ✖ Sliding doors are likely to be more costly than bi-fold doors.
• ✖ Dirt can pile up along the track of sliding track patio doors, causing problems.
• ✖ Accumulation of dirt in tracks can cause drain hole blockages.

French Doors

French doors will always be a fashionable addition to any home. They occupy a similar amount of wall space as patio doors. However, they can open outwards into the garden, offering them a different feel – they physically connect the interior and exterior spaces.

French doors are frequently paired with panelled windows on either side to enable even more light into the home, but they can also be used independently. With modern sealing, they're the ideal choice for a British homeowner, providing excellent insulation in the winter and allowing you to open the house to the sun in the summer.

Pros

• ✔ Lightweight and simple to open.
• ✔ French patio doors are less expensive than bi-fold or sliding patio doors.

Cons

• ✖ With time, hinges could become noisy and stiff.
• ✖ If you go to open one of the doors throughout windy weather, it may pull you forward if the wind also catches the door

Bi-Folding Doors

The bi-fold door is the final major type of patio door. This long, concertina-like installation allows you to strip away a whole wall (or part of one) to completely open your house to the garden.

Bi-fold doors are made of individual glass or uPVC panels with hinges throughout each panel and door frame. This means they can fold to one side concertina-style to fully open one wall more efficiently than any other type of patio door.

Sliding doors still require one panel's width to be closed, and French doors struggle to be bigger than two panels, so only a bi-fold door will do if you want a wide, completely unobstructed entryway in your home and garden.

Due to the number of configurations available, bi-folds can take longer to develop and organise than other types. However, if you have a large space that you want to open to the garden, a bi-fold door is probably a pretty good choice.

Pros

• ✔ Maximises space and plenty of natural light.
• ✔ Highly versatile for different room layouts.
• ✔ Lightweight and easy to operate.
• ✔ They do not necessitate a lot of upkeep.

Cons

• ✖ The cost of bifold doors is exorbitant.
• ✖ Not as secure as other types of patio doors.
• ✖ Bifold patio doors do not provide the same level of accessibility as French and sliding patio doors.

Checklist: Hiring Contractors to Install Patio Doors
