As a comparison between the difference in double glazing prices between different styles of windows, let’s take the cost and installation charge of a single 100cm x 100cm window with a white uPVC frame;

  • A casement window costs between £325 to £420
  • A sash window costs between £640 to £820
  • A tilt and turn window costs between £490 to £625
  • A dual turn window costs between £575 to £670

That is quite a range of prices between styles!

What’s more:

Any design or styling changes, like the colour of the frame and handle colour, will add to the double glazing cost.

  • Do you want gold or a chrome handle?
  • Does wood finish sound more appealing to you?
  • Would you want the design on the glass?

Be prepared to pay extra for those!

Just like the style of the window, the size also plays a huge role in determining the double glazing cost of your windows.

A typical 1800mm x 1200mm window might cost you £350, while a small bathroom window is more than half the price at £150!

The type of glass you want also has an effect on your double glazing cost. Toughened glass is a requirement if your window is 800mm or less from the floor.

This is a specially treated glass that shatters into harmless crystals when it breaks.

Since normal glass breaks into shards that can potentially be dangerous, this special glass offers higher safely.

As a result, you can include an additional 20% on the double glazing cost of each unit. Similarly, Georgian bars or lead designs can add at least £30 to your individual unit’s double glazing prices.

The cost to replace one or few of your window will depend on not just the price of the window unit but also who you get to install it.

A specialist company might charge you £75 per window, while a small local company run by one man might do it for £50.

A large well-known company comes with a reputation and quality assurance. They also tend to have more styles and options as they have greater warehousing capacity. The downside to using them is the high cost and the fact that they might have a minimum job size.

A small company might not have the means to stock a large variety of window designs and variety. However, they have no ‘minimum order’ and their double glazing prices are lower. There is also the fact that, since they are a local business, they need to maintain their reputation. If they do poor quality work, the word gets around and they lose business.

Being local also allows you to see their work first hand. You can ask them to tell you where they have worked in your area and get reviews from their previous clients!

Noise reduction is another advantage of double glazing. If you live near busy traffic you may find having double glazed windows installed beneficial. Triple glazing is also an option if you are concerned about noise pollution.

What are the Prices for Double Glazed Doors?

We have discussed the price of the windows. For doors, the factors that make up the cost aren’t so different. Your door size, style and glazing will all, of course, contribute to the overall cost. Prices can vary significantly when it comes to design and material.

For example, composite doors are likely to cost more than a uPVC entrance door. This is because a composite door is made from a combination of different materials.

It is, therefore, a more complex product and takes longer to manufacture. They are also seen as higher quality and are often chosen for replacement front doors.

Composite doors are attractive and come in a range of colours and styles. Furthermore, you can also accessorize them with options such as knockers, spyholes and door numbers.

Should You Pay For Energy Efficiency in Your Double Glazing Cost

It might seem like a needless addition to your double glazing cost, but getting energy efficient units can make a huge difference in your annual energy bills. Studies have shown that even a rating of C can help bring down your yearly energy bills by around £50. A rating of A or A++ might even get you a saving of £75 a year!

That can translate into considerable savings over time. How does poor quality double glazing cost you in terms of your house’s heating?


  • By losing heat rapidly, it ends up making your heating work harder!
  • A good quality double glazing has two layers of glass with a sealed layer of vacuum or argon between them. This acts as insulation, preventing heating from inside the house from escaping.
  • Since the heat remains trapped inside, your heaters don’t have to work as hard to maintain the temperature inside.
  • This not only helps your household budget but also the environment!

And the best part?

The insulation is helpful in not just keeping heat in, but also keeping noises out!

How Do You Keep Your Double Glazing Cost Down?

To ensure that, you will need to shop around and compare quotes. We recommend you do not settle for the first quote you get. It is always a good idea to get double glazing prices from more than 3 sources.

You may find that a big supplier has the exact design and material that you wanted. They can install your units for you with the strictest quality standards, and you are happy to pay for it.

On the other hand, a small local installer might be willing to go the extra mile for you and helps you keep your double glazing cost to a minimum. He may be willing to replace a single window whereas the large company might have a minimum job size.

By shopping around, you will be able to identify the right options to suit your needs perfectly. You might also get a competitive quote by shopping around at the right time. Since December is considered the slowest month for windows installation, you are likely to get a very low double glazing cost quote.

Additionally, salesmen often start the sales pitch with a higher double glazing quote. You can get the double glazing prices lowered simply by asking for a lower price. The more you negotiate, the better the double glazing price you will be able to get for yourself!

What are the Best Window Frames?

When it comes to the frames of your windows, the thickness varies from 14 to 28mm. This depends on how big the window is.

The thicker the window the better its energy performance will be. Retaining heat in your property and preventing the cold from outside entering your home. Thicker frames will also more effectively provide sound reduction.

uPVC is a popular frame material as it is affordable. It is durable and low maintenance. You won’t need to worry about spending time or money on the upkeep.

Furthermore, they won’t suffer from rotting or discolouration. Also, they won’t warp over time.

However, some people prefer aluminium. It is a more expensive material choice for your window frames. However, it is robust, strong and lightweight.

This makes it a flexible material that can result in higher glazing to frame ratio. This will give you unobstructed views.

Who is the Cheapest Double Glazing Company?

As we have discussed, the cost of double glazing can vary from company to company. If you want cheap double glazing it is certainly a good idea to shop around.

Consequently, make sure you compare quotes from at least 4 double glazing companies. This will give you an overview of the average cost of double glazing per window.

This will help you decide on the best solution for your home.

Other information to consider is how long the company has been established. It is also worth reading their reviews.

If you can look at previous and present projects they’ve worked on this is also useful when making your decision.

It is worth finding out if they will offer a bulk purchase discount or if they quote by the single price of a double glazed window.

You may want to choose a local double glazing company or a national one. There are benefits to both.

Therefore, our recommendation is that you get multiple quotes and ask all the questions you need to.

Above all, this will give you a good overview and hopefully competitive uPVC window prices.
