Patio Door Prices by Type

The biggest factor affecting cost is the style of patio door you choose.

French Patio Doors Cost

French patio doors are usually the most affordable option. Supply-only prices typically range from £630 to £2,800, depending on material and finish.

They use a simple side-hinged mechanism with two panels that open inward or outward. Because the system is mechanically straightforward, they generally cost less to manufacture and install than sliding or bifold designs.

Installed costs often start from around £800 for basic uPVC models fitted into an existing opening.

French doors are particularly suitable for:

• Smaller openings

• Traditional properties

• Homeowners working within a tighter budget

Sliding Patio Doors Cost

Sliding patio doors typically cost between £800 and £3,550 supply only.

These doors operate on horizontal tracks, with one or more panels sliding behind another. They are popular in modern homes because they maximise glass area and allow plenty of natural light.

Sliding doors are generally mid-range in price. They are more complex than hinged French doors due to:

• Track systems

• Roller mechanisms

• Larger glass panels

Installation may also require precise levelling to ensure smooth long-term operation.

Bifold Patio Doors Cost

Bifold patio doors are usually the most expensive patio door style. Supply-only prices typically range from £1,760 to £6,745, depending on material and the number of panels.

They consist of multiple panels that fold and stack to one side, creating a wide opening. This makes them popular for large extensions and open-plan layouts.

Costs increase with:

• More panels

• Wider openings

• Higher specification glazing

• Structural reinforcement

Bifold systems often require additional structural support above the opening, which can add to overall project costs.

Patio Door Costs by Material

The material you choose affects both price and long-term performance.

uPVC Patio Doors

uPVC is usually the most affordable material option.

Advantages:

• Lower upfront cost

• Low maintenance

• Good insulation performance

• Resistant to weathering

uPVC French doors are often the cheapest entry point into patio-style access.

Limitations:

• Thicker frames compared to aluminium

• Less premium appearance

Aluminium Patio Doors

Aluminium patio doors are typically mid to high range in price.

Advantages:

• Slim frame profiles

• Contemporary appearance

• Strong and durable

• Suitable for larger spans

Aluminium allows for larger glass panels with narrower sightlines, which is why it is commonly used for sliding and bifold systems.

Limitations:

• Higher initial cost than uPVC

• May require thermal breaks for optimal insulation

Timber Patio Doors

Timber doors usually sit at the higher end of the pricing scale.

Advantages:

• Traditional aesthetic

• Natural insulation properties

• Can be painted or stained

Limitations:

• Requires regular maintenance

• Higher long-term upkeep costs

• Generally more expensive than uPVC

Timber may suit period properties or homeowners prioritising appearance over maintenance convenience.

Patio Door Installation Costs Explained

Installation costs vary depending on whether you are replacing existing doors or creating a new opening.

Typical labour rates range from £30 to £80 per hour, depending on region and expertise.

For a standard installation into an existing opening, expect:

• £500 to £1,200 for fitting

For a full replacement, including removal and disposal:

• £800 to £3,500 total project cost

If you are creating a new opening, costs can rise to £2,000 or more due to:

• Structural alterations

• Installation of steel lintels or RSJs

• Possible involvement of a structural engineer

• Brickwork and plastering adjustments

Structural work often adds more to the total cost than the door itself.

What Affects the Cost of Patio Doors?

Several key factors influence the final price:

• Door size and width of opening

• Number of panels

• Double or triple glazing

• Security upgrades and multi-point locking

• Frame colour and finish

• Threshold type

• Structural reinforcement

• Regional labour variation

For example, triple glazing increases the weight of each panel and may require stronger mechanisms, raising both supply and installation costs.

Larger door spans also require heavier frames and potentially larger structural beams above the opening.

Alternatives to Patio Doors

In some cases, a full patio door system may not be necessary.

If your project involves separating rooms rather than accessing the garden, Internal Doors may be more appropriate and significantly more affordable.

For secure outdoor access without large glass panels, External Doors can provide durability and weather resistance at a lower cost than sliding or bifold systems.

Choosing the right solution depends on your space, layout, and budget.

Are Patio Doors Worth the Investment?

Patio doors can improve natural light, ventilation, and connection to the outdoor space. They can also enhance property appeal, particularly in modern extensions and kitchen renovations.

Energy-efficient double glazing can help reduce heat loss, while secure locking systems improve safety.

Although they represent a moderate to significant investment, well-installed patio doors can provide long-term durability and functional value.
