Sliding doors are often part of a bigger plan, like an extension, a home upgrade, or a better flow from inside to garden. Clean lines, more light, and a modern finish sound great… until it’s time to work out the cost.
That’s when things get tricky.
Prices vary widely. Material, size, glazing, and installation all play a role. One quote looks manageable, but the next is double.
This guide breaks down what sliding patio doors really cost in the UK this year, with clear price ranges, key cost factors, and what to expect when budgeting for supply and installation. Sit back and enjoy the read our guide on sliding doors pricing in 2025; your pocket will thank you.
Average Cost of Sliding Patio Doors in the UK (2025 Guide)
Sliding patio doors in 2025 typically cost between £800 and £3,500 for supply only, or £1,500 to £5,500 including installation.
The two biggest factors that affect the price are material and size. Aluminium costs more than uPVC. A three-panel setup costs more than two. Glazing upgrades, custom colours, and hardware can all push the price higher.
Here’s a simple breakdown of what you can expect to pay:
| Door Type | Supply Only | Supply and Fitting |
|---|---|---|
| uPVC (2-panel) | £800–£1,200 | £1,500–£2,200 |
| Aluminium (2-panel) | £1,500–£2,800 | £2,500–£4,000 |
| Timber (bespoke) | £2,000+ | £3,500–£5,500 |
Larger doors, triple glazing, or structural changes can push the cost higher, but this table covers the most common setups seen in UK homes today.
What Affects the Cost of Sliding Patio Doors?
Sliding patio door prices aren’t one-size-fits-all. A few key factors have the biggest impact on how much the final total adds up to, both for supply and installation.
Material
The material you choose will make a difference and definitely affect the final quote you get.
- uPVC is the most budget-friendly but comes with thicker frames.
- Aluminium costs more but offers slimmer sightlines and a modern look.
- Timber sits at the top end, which is often bespoke, with a warm finish and more upkeep.
Size & Panel Count
Wider openings or extra panels mean more materials, more glazing, and more labour. A basic 2-panel setup will cost less than a 3- or 4-panel configuration.
Glazing Specification
Basic double glazing is standard, but upgrades like triple glazing, low-E coatings, or laminated glass for security and soundproofing add to the price.
Hardware & Security
Handles, soft-close mechanisms, and high-spec locks come in a range of quality levels. Features like multi-point locking systems or integrated blinds increase both cost and peace of mind.
Installation Complexity
Retrofitting into an existing opening is usually straightforward. Creating a new opening, widening an existing one, or working around structural elements adds labour and may require lintels or additional support.
Pro Tip: Always book a proper site survey before committing to anything. It’s the best way to spot hidden issues, like damaged brickwork, missing lintels, or openings that aren’t square, all of which can raise the final price if missed early on.
Sliding Door Materials Compared: Cost, Durability, Style
Choosing the right material is one of the biggest decisions, not just for price, but also for how the doors will look, feel, and hold up over time. Here’s how the main options stack up:
| Material | Cost | Durability | Look & Feel | Considerations |
|---|---|---|---|---|
| uPVC | £1,500–£2,200 | Moderate | Clean but bulky frames | Great insulation, limited style range |
| Aluminium | £2,500–£4,000 | Very high | Slimline, modern, high-end finish | Costs more, excellent long-term value |
| Timber | £3,500–£5,500+ | Depends on upkeep | Warm, natural, traditional | Needs maintenance, fully bespoke |
If budget is the priority, uPVC is the go-to. For a sleek, low-maintenance option, aluminium always wins out. Timber fits best in heritage homes or premium builds where character matters most.
How to Budget for Sliding Door Installation
Installation costs vary depending on what’s already in place. For a straight swap with no structural work, the labour can fall as low as £500.
More complex jobs, especially those involving large openings, poor access, or extra finishing, can raise the total to £1,500 or more.
A few things to keep in mind:
- Structural changes: Enlarging an opening often means adding or upgrading a steel lintel, which adds cost and time.
- Access issues: Upper floors, narrow side paths, or internal-only access can make the job harder and more expensive.
- Permissions: Depending on the local authority, large openings, listed buildings, or flats may require planning permission or building control approval.
Are Sliding Patio Doors Worth the Cost?
For many homeowners, the benefits of sliding patio doors go beyond just looks.
They improve natural light, create a stronger connection to the garden, and help rooms feel bigger and brighter. Well-installed doors with modern glazing also boost energy efficiency, cutting down on heat loss through large openings.
Over time, they can add value to a home, especially when quality materials like aluminium or bespoke timber are used. Low maintenance and long-term durability make them a smart upgrade for both day-to-day living and future resale.
For most, the upfront spend is offset by the comfort, light, and space they bring to everyday life.
On A Final Note;
Sliding patio doors aren’t a small investment, but the right choice can bring long-lasting value in how the space feels, functions, and performs year-round.
The key is understanding what drives the cost, from materials and glazing to installation complexity.
Planning ahead with a clear budget, a proper site survey, and a fixed quote can help avoid delays or unexpected costs.
