Patio doors make a lovely addition to your home. They improve the aesthetic appeal, allow more sunlight, and enhance the seamless transition between the outdoors and the indoors. However, purchasing and installing a patio door comes with a price, and that price differs depending on the type of door, material, glazing, and even if any structural changes need to be done.
This guide offers a comprehensive outline of expected expenses for anyone wishing to install or replace a patio door. Consulting a patio door specialist can help ensure you make an informed decision tailored to your needs.
Factors Affecting the Cost of Patio Doors
Cost of patio doors will most certainly differ, from the material selected to the patio door design and the complexity of the construction work. Knowing all of these factors will allow you to come up with a realistic budget.
Your choice of patio door determines its associated costs. Here are some of the most common options available along with their price brackets:
1. Type of Patio Doors
Bi-fold doors are the most expensive option but offer a modern touch to your space while sliding patio doors are relatively cheaper and provide a traditional touch. French doors are highly recommended if you wish to add a touch of elegance.

| Sliding Patio Doors | £500 – £2,500 |
| French Patio Doors | £600 – £3,000 |
| Bi-Fold Patio Doors | £1,500 – £6,000 |
Sliding patio doors are the most common and cost-effective option, whereas bi-fold doors offer a high-end, modern solution. French doors provide a classic and elegant alternative.
2. Material Choices
The choice of material affects the cost as well as the longevity and energy efficiency of the patio doors.
| Material | Price Range (Per Door Set) | Pros | Cons |
| uPVC | £500 – £1,500 | Affordable, low maintenance | Less durable, limited colour options |
| Aluminium | £1,500 – £4,000 | Sleek, modern, highly durable | More expensive |
| Timber | £1,500 – £3,500 | Classic look, natural insulation | Requires regular maintenance |
| Composite | £2,000 – £5,000 | Best durability and insulation | Expensive |
3. Glazing Options
Glazing impacts insulation, security, and cost. You can choose from:
- Double Glazing – Standard option, good insulation (£100 – £400 extra).
- Triple Glazing – Enhances energy efficiency and noise reduction (£300 – £700 extra).
- Toughened or Laminated Glass – Increases security (£200 – £600 extra).
- Low-E Coated Glass – Improves energy efficiency (£150 – £500 extra).
4. Door Size and Customization
Larger doors require more material and structural work, leading to higher costs. Custom finishes, colours, and frame options can also increase the price by 10-30%.
