How Much Do Sliding Doors Cost in 2026?

Sliding doors are often fitted for patio areas and provide plenty of natural light to enter and offer a smooth opening and closing mechanism that really opens up your space. Sliding doors are an in-demand choice for many homeowners looking to renovate and upgrade their home, so knowing how much they cost is worth knowing before making the investment.

The price of sliding doors will vary depending on several factors, from dimensions and material to condition and installation. The costs can range anywhere from a few hundred pounds to thousands. At Green Doors, we sell sliding patio doors that suit all types of budgets and bring you a complete guide on how much sliding doors cost. By the end, you’ll know which options will work best for your budget and home.

What Are Sliding Doors?

Sliding doors are doors that open horizontally by gliding along a track, rather than swinging inward or outward. They are commonly used for patios, wardrobes and room dividers, offering space-saving functionality, smooth operation and wide openings that maximise light and accessibility.

What Affects the Cost of Sliding Doors?

The final price of your sliding door will depend on several factors, with some like material affecting the cost more than others.

Material (uPVC, Aluminium, Timber)

The frame of every sliding door will be made from a specific type of material which affects the cost. Some materials are cheaper to make than others and offer certain advantages. The most common materials used for sliding doors include uPVC, aluminium, timber and composite.

A quick breakdown of material costs for new sliding doors:

• UPVC: ~£400 – £1,600 per door
• Timber/composite: ~£2,000 – £5,000+ per door
• Aluminium: ~£2,000 – £6,000+ per door

First off, uPVC is perhaps the most widely used material because it is the cheapest. It’s cost-effective because it’s quick and easy to manufacture, and it offers good insulation. While relatively easy to maintain, the downside of uPVC is it can be prone to warping, yellowing and losing alignment. While it’s a low-cost initial investment, some homeowners do find themselves spending on fixes further down the line.

Sliding doors can also be made from timber and composite materials. If a sliding door is made of solely timber, you’ll have a classic look but will be spending more on the initial buy as well as regular maintenance. If sliding doors are made from wood plastic composite (WPC), the frame will be very durable, but it can be heavy and bulky to operate.

Aluminium sliding doors are one of the most durable options and can be designed with sleek sightlines that allow for maximum panel sizes. It can also be powder coated in different colours, offering more customisation compared to uPVC. This typically increases the price, especially with more glass panels or textured finishes. But, the longevity and low maintenance of aluminium sliding doors will help you save in the long term.

Size & Number of Panels

The bigger the sliding doors are, the more expensive they’ll be. Smaller frames require less material, but multiple panels will mean you’ll be paying more. Sometimes, choosing a configuration with fewer panels, where the doors are at a wider size rather than having multiple doors, will provide a cheaper version.

Glass & Energy Efficiency

As the large glass panels are a key feature of sliding doors, it’s important not to overlook the type of glazing when figuring out the final price. While choosing double- or even triple-glazing will be more expensive, both options will help improve the energy efficiency of your home, helping to maintain heat in your home when it’s reflected inside.

For new sliding doors, there are also options for UV light protection or solar control glass, which again will increase the price. However, the inclusion of more sophisticated glazing can help you save on energy bills and provide a comfortable home temperature no matter the time of year.

Installation Requirements

The configuration of your chosen sliding doors will ultimately affect the price of installation. Some installations will require structural changes to your home, adding on costs for labour for things like modifying walls, adjusting floor levels or installing additional support.

More complex installations and access requirements may also mean you’ll be charged more, such as installing sliding doors above the ground floor. Often, the final installation price won’t be included, so always check the fine details.

Sliding Door Prices by Type

Brand New Sliding Doors Cost

Brand-new sliding doors mean the doors are unused and recently manufactured. They can either be standard, pre-made sizes or custom-built.

Depending on the manufacturer and supplier, as well as factors like size, material and configuration, brand new sliding doors can cost anywhere between £1,200 and £100,000.

At the lower end, you’ll find basic uPVC models in standard sizes, while mid-range options, like aluminium or composite, usually fall between £1,200 and £2,500. High-end, large-span or premium aluminium systems with advanced glazing can exceed £100,000.

Premade Sliding Doors Cost (Lower-Cost Alternative)

Premade (off-the-shelf) sliding doors are also manufactured in standard sizes and kept in stock, making them a more affordable and quicker solution. These typically cost between £500 and £2,500, depending on the material and quality. Because premade sliding doors aren’t custom built, installation is usually faster and cheaper, but you’ll have fewer choices in terms of sizing, finishes and configuration.

For homeowners prioritising value and speed, we at Green Doors provide some of the most cost-effective options across both premade and brand-new ranges.

Made-to-Measure Sliding Doors Cost

Made-to-measure sliding doors are custom-built to fit your exact opening, giving you far greater flexibility in design, materials, colours, glazing and hardware.

While buying brand-new sliding doors offers far more options and will be built specifically for your home’s exact measurements, both the lead time and cost will be higher.

Although they come with longer lead times and higher upfront costs, made-to-measure sliding doors offer a precise fit and a more tailored finish, which is ideal for non-standard openings or design-focused projects.

Why Premade Sliding Doors Are the Most Cost-Effective Option

Lower Manufacturing Costs

Premade sliding doors are produced in standard sizes and batches, which significantly reduces manufacturing costs. Because there’s no need for a bespoke design, custom tooling or made-to-order production, suppliers like Green Doors can offer them at a lower price point.

For homeowners, this means accessing reliable, brand-new doors without paying the premium associated with customisation.

Faster Availability

Since premade sliding doors and other types are held in stock, they’re available for much quicker delivery compared to made-to-measure options. This reduces lead times from weeks to, in some cases, just days. Faster availability not only speeds up your home improvement timeline but also helps lower labour costs.

Ideal Use Cases (Extensions, Replacements, Rentals)

Premade sliding doors are well-suited to a range of projects. For example, they’re a practical choice for home extensions with conventional openings, straightforward replacements of existing doors or rental properties where keeping costs under control is a priority. In these scenarios, solutions offered by Green Doors provide a strong balance between affordability, quality and convenience.

We sell many sizes that are not standard; it is about the following:

• Being flexible with your sizes
• Choosing a set
• Building around it.
