double glazing cost for a new window


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.

Types of Double Glazed Windows

Standard Window Types

Double Glazed windows come in a number of design styles. These include Casement, French Casement, Sash, Tilt and Turn. Other styles are Flush Sash, Bi-Fold Windows, Bay Windows and Bow Windows.

Casement Windows Casement windows feature a single-lever latch design that allows for smooth hand operation. They are the most common choice of uPVC window. Casement windows can be installed anywhere within the home. They have a timeless appeal combined with modern functionality.

French Casement Windows French casement windows provide a wide opening. Both sashes open to about 90 degrees. When both windows are opened, one casement carries the central mullion. This provides good ventilation and unrestricted views.

Sash Windows uPVC sash windows are designed to achieve a more traditional look for a home. The sash window is a classic style. This beautiful design marries both style and functionality. This gives you a traditional looking yet long lasting window. Mock sash windows are also available. They give the style of a sash window but can open like a casement window. Mock sash windows are generally cheaper than operational sash windows.

Tilt and Turn Windows The uPVC tilt and turn window is extremely easy to operate with a dual-action movement. This provides access to 3 different window operations: locking, open and tilting. These windows are particularly popular in upper floor windows and high rise properties. This is because the tilt and turn functionality allows easy cleaning from inside the property.

Projection and Bi-Folding Window Types

Bow Windows Units of similar size are joined together creating a curved edge. This results in a wonderful, extended outside view. The bow window will blend beautifully into surrounding brickwork, with no unsightly corners.

Bay Windows Like bow windows, bay windows will add a touch of elegance to a room. Bay windows protrude from the property in a more angular shape. They are not curved like bow windows. A traditional bay window protrudes at 45 degree angles. An alternative is a window with a 90 degree projection. This is called a box bay window. A popular addition to a bay window is a window seat.

Bi-Fold Windows These practical windows are ideal for use in conservatories and orangeries. This is because they give you the option to be able to fully open up the side of the room. They provide fantastic panoramic views of the outside. They are great for ventilating a room on a hot day. Bi-fold windows are also a stylish and attractive addition to a home.

Why is Double Glazing Better?

The main reason behind installing double glazing into homes is the energy efficiency. Double glazed windows are intelligently designed to keep warm air trapped inside your home. They are also designed to keep the cold out.

The energy performance of double glazing windows are rated on a scale of A++ to G. Grade C is the lowest a window fitter may install while still complying with government building regulations. You should aim to purchase as highly graded a window as possible. This will let you benefit from the best energy efficiency and insulation.

This helps to reduce energy bills. It can also decrease your carbon footprint. This may well also save you money in the long run.

It also regulates the temperature inside your house. This makes it a comfortable and inviting place to spend time.

uPVC windows won’t inhibit natural light from entering your home. This makes it an excellent choice for vibrant and bright spaces.

Double glazing protects your home against the elements and adverse weather conditions.

It will also add a layer of security to your home. Single or secondary glazing simply cannot match this.

If security is a consideration, ask your double glazed windows supplier about high security locking systems. They will be able to show you what is available.

The locking system you choose can affect the cost of double glazing so it is good to bear this in mind.

What is the Cost of Secondary Double Glazing?

The cost of secondary glazing is cheaper than that of double glazing. Secondary glazing is when an extra layer of glass is installed on the inside of an existing single glazed window.

This is different to double glazed windows. Double glazing uses two sheets of glass with a gap between. This creates an insulating barrier.

Secondary glazing is cheaper than double glazing. It is not as effective at keeping heat within your property. It also has a lower level of noise insulation and security.

Most properties that are within conservation areas benefit from secondary glazing. It means the original window glass is kept in place.

This can also be true of listed properties. If you have a listed property it is worth asking about secondary glazing.

Secondary glazing is suitable for period properties that need to keep the original features without too much change. Secondary glazing is a discreet and efficient modernisation.

It allows a property to benefit from better thermal efficiency.

Double Glazing Vs. Triple Glazing

You can increase the effectiveness of your windows by upgrading to triple glazing. This will raise the cost of your double glazing prices.

However, it can also heighten the security and energy efficiency of your home.

A room with triple glazing can be warmer than those that have single glazing or double glazing.

This makes triple glazing a popular option for those looking to feel the benefits in the colder months. It is also popular among homeowners that live near busy roads or under flight paths.

What is the Cost of Double Glazing an Entire Home?

The cost of double glazing a home will depend on many factors including product style and type of glazing. Of course size, colour and security extras will also affect double glazing prices.

The more windows and doors you want to purchase the more you will have to spend. However, the average cost of double glazing per window can be slightly cheaper when you are buying multiple windows at a time.

You’ll most likely find that a home improvement company will give you a good deal if you’re replacing a large number of windows and doors in one go.

Some people may ask ‘Why is Double Glazing so Expensive?’ but if you shop around you can generally find a good deal. The cost of double glazed windows will vary so with multiple quotes you can compare prices.

Does The Size of Windows Change Double Glazing Prices?

The size of your windows will affect the cost of double glazing. Small windows like a bathroom window will be cheaper to replace than larger windows. However, some companies will have a minimum order price. If you have several windows to replace, it may be more cost effective to have them all done at the same time.

If your windows are not on the ground floor, double glazing prices may also include setting up scaffolding. This can affect the individual price of a double glazed window.

What is the Double Glazing Cost For a 3 Bed-Semi?

On average, the cost of double glazing a 3 bed house can be between £3000 and £5000.

It will, of course, depend on the glazing product you choose. Other considerations are energy rating, locking systems and frame colours.

If you shop around, get multiple quotes and compare prices, you can get very competitive uPVC window prices. You will obviously want to choose an installer you trust and are happy with so not all your considerations will be price-led.

When Should I Replace my Double Glazing?

Double glazing units tend to have a life span of up to 20 years. Around the 15-20 year mark is where you might consider getting your double glazed windows replaced.

Lots of suppliers will offer a warranty. This can vary in length so it is a good idea to ask about the warranties on offer.

One of the benefits of double glazed windows is that they are low maintenance. During the lifespan of your windows, maintenance tasks should be minimal.

Usually, just cleaning them regularly should be enough to keep them looking good and in optimum condition.

What Is The Double Glazing Cost to Replace a Window?

In certain cases, you might not need a complete overhaul of all your windows. You can control your double glazing cost by simply replacing the damaged window, or windows. 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!

You may like the appearance of your window, and it is performing up to your expectations. There might not be a need to spend a great deal of money in replacing it when you can get it fixed.

You will need to consult an expert in such a situation. A simple survey will tell you if it is possible to repair it, or if you need to replace the whole unit.

You might want to keep your double glazing cost down by getting it repaired. However, if the survey says that repairing it is not viable, then you will have to replace it. A repair in such a situation would be like a band-aid solution, and might end up costing you more in the long run.

You also get better value from your property if you maintain the appearance and energy-efficiency. Trying to compromise on the replacement double glazing cost might prove expensive when it is time to pay your energy bills!

What are the Benefits of Double Glazing?

There are many benefits to having uPVC windows installed in your home.

Double Glazing is an investment and a worthwhile one at that. Despite the initial outlay, double glazed windows can save you money in the longer term.

Double glazed windows help retain heat, keeping your home warmer for longer. You’ll find your energy bills may reduce over time. You may also become less reliant on boilers and central heating radiators.

Double glazed windows can significantly improve the security of your home. There are many high security locking options to choose from. This can save you money on insurance premiums. It will also give you peace of mind about the safety of your family and home.

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 the 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.

Our online double glazing cost calculator also includes a multitude of door styles. Why not have a browse through to see the different styles and prices?

It also includes many single doors and also offers a patio door cost calculator. French door prices and bi-fold door prices are also available.

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 a 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?

You may not be looking for the cheapest double glazing cost as that might not cover your needs. However, you do want to get the most competitive double glazing prices that you can get. How do you ensure that the double glazing prices you are paying are the best in the market?

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. 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.
