Sliding patio

£1,000 – £2,100

The type of door and material used for the frame are the two main factors that will impact the price.

For example, when it comes to type, bi-fold doors cost more than any other style as they have a more complex design and thus require more time and resources to manufacture.

As for the frame, the main options are uPVC, composite, wood, and aluminium. uPVC is usually the most popular as well as the most affordable material. Aluminium tends to be the most expensive, but it’s more durable and the most aesthetically pleasing.

Factors affecting the cost of double glazed doors

Other than door type and frame material, several other factors can impact the cost of double glazed doors. Here are the most important ones to consider:


The cost of double glazed doors can vary widely depending on size. Expect to pay more for larger-than-average or custom sizes.

Glass type

Glass options for double glazed doors include:

  • Annealed (float) glass
  • Laminated glass
  • Toughened glass
  • Self-cleaning glass
  • Acoustic glass
  • Coated glass
  • Low-emissivity (low-E) glass

Each type has its advantages, drawbacks, and costs. You’ll pay more for enhanced glass types, like laminated or toughened glass, than basic types, like annealed (float) glass, due to the extra features in the former.


Professional installation is recommended for double glazed doors to ensure proper fitting and to prevent costly mistakes. Some suppliers include the costs of installation in their pricing of the unit.

That said, if you have the necessary skills, tools, and experience, you can save on total costs by taking on the installation yourself.

Tips for how to reduce the cost of double glazed doors

If the price of double glazed doors is putting you off, you’ll be pleased to know that there are a few things you can do to cut back on costs. We’ve listed a few ways below, to give you a head start.

Compare prices

Getting quotes from multiple suppliers and comparing them will give you a good idea of what constitutes a reasonable price.  It can also help you negotiate a lower price with your preferred supplier.

Luckily, we can help you speed up this process with our easy-to-use quote tool.

And speaking of negotiating, don’t be afraid to ask for a discount from your dealer. Many are willing to offer one, especially if you’re purchasing multiple doors or if you combine the purchase with other products.

Use local suppliers

Buying from local suppliers, where possible, can be more cost effective as it eliminates or reduces shipping or transportation costs.

Opt for standard sizes

Go for standard sizes over custom sizes if possible. Custom sizes tend to have a higher price tag due to additional manufacturing costs.

Choose materials wisely

Framing material options like aluminium or wood might offer better aesthetics, but they come with a higher price. If saving money is a priority, go for a more affordable option like uPVC.

Consider partially glazed doors

If budget constraints are a concern, consider partially glazed doors. Their costs run lower while still delivering some of the benefits of their fully glazed peers.

Pros and cons of double glazed doors

Before you invest in a set of double glazed doors, it’s always a good idea to weigh up the pros and cons. Thankfully, we’ve done the hard work for you.


  • Energy cost savings
  • Noise reduction
  • Improved security
  • Higher home resale value


  • Require a higher financial investment initially
  • Can trap heat in the summer
  • Prone to condensation
  • Not repairable in case of damage

Advantages of double glazed doors

The design of double glazed doors helps prevent heat transfer. Installing these doors can improve your home’s energy performance rating and save you money on heating bills. According to The Energy Saving Trust, the average home can save up to £235 per year on energy bills by upgrading from single to double glazing.

The dual layer of glass and insulating gas in double glazed doors helps keep unwanted noise outside. Additionally, these doors are harder to break than their single glazed counterparts and will therefore do a better job of keeping your home safe from intruders.

Combined, all these benefits can make your home more appealing to prospective buyers and boost its resale value. In fact, double glazing can increase your home’s value by up to 10%.

Disadvantages of double glazed doors

Double glazed doors require a higher initial capital investment than other types of doors.

Also, while keeping heat inside the house might be beneficial during winter, it can be a  disadvantage during summer. More specifically, double glazed doors can lead to excessive heat accumulation indoors during hot weather.

Furthermore, if the sealing on your double glazed door breaks, moisture can enter the space between the glass layers, resulting in condensation. If this happens, you might have to replace the entire unit.

Are double glazed doors worth it?


While double glazed doors cost more initially, the long-term benefits including energy cost savings, sound insulation and increased resale home value make them a worthwhile investment.

Types of double glazed doors

There are four main types of double glazed doors.


Double glazed front doors offer a secure, stylish entrance to your home. They’re available in a vast range of finishes and designs and can be fully glazed or partially glazed. Many also come with laminated or toughened glass as standard, which adds an extra layer of security.

French doors

French doors consist of two side-by-side panels that open inward or outward along a central frame. They’re renowned for their versatility, particularly their ability to complement both traditional and contemporary architectural styles.

You can get these doors in various frame materials, including aluminium, uPVC, and wood.

Patio sliding

Patio sliding doors consist of panels that slide horizontally on tracks. When opened, the panels overlap, creating an opening one can walk through.

Sliding patio doors are easy to operate and require minimal space, making them an excellent option for smaller areas. uPVC is the most popular frame material for these doors, but you can also get them in wood, composite, or aluminium.

Bi-fold doors

Bi-fold doors have multiple panels that fold and stack against one another when you open them. They’re an excellent choice for large openings, specifically those leading to gardens, patios, or decks.

Like French and patio sliding doors, bi-fold doors are available in various frame materials, including uPVC, wood, and aluminium.

Another way to insulate external doors is to build a double glazed porch around them. Porches are basically an home extension, so they come with the benefit of extra space as well as insulation.

Which type of double glazed door is right for you?

The right type of double glazed doors will depend on several factors, including your needs, preferences, home layout, and your budget.

If you aren’t sure which type is right for you, it may be helpful to consult with a professional or visit showrooms to see and compare different options before you make a decision.

Double glazed uPVC doors cost between £600 and £2,000, depending on the type of door, e.g. front door, French door, sliding patio or bi-fold door. The cost can also vary depending on the size of the door.

uPVC doors are cheaper than composite doors. One reason for that is that composite doors are built from more expensive materials, and their production process is more complex.

Composite doors also offer superior durability and have a longer lifespan than uPVC doors.

Double glazed doors can last up to 35 years with proper maintenance. Most manufacturers offer warranties for issues such as fogging, condensation between panels, and failure of seals.

The warranty period can vary between different manufacturers, but it’s typically in the range of five to ten years.
