How Much is the Average Price for New Windows? New Windows Cost 2021

The average price for new windows ranges from £500 to £2,260 for an individual new window.

For a small flat with 4 windows, the average price for new windows would cost around £2,140. This figure is based on the cost of double glazed uPVC casement windows and their installation.

Similarly, for a house with 8 windows, the average price for new windows would cost around £4,500, including installation. A house with 10 windows could have an average price for new windows that could cost £5,450, and a 15-window house would have a new windows cost of £8,450.

However, these estimates are very basic, and they don’t take into consideration anything other than a standard number of windows with a uPVC frame and the installation costs. The problem with going by these average price figures for new windows is that you might end up with a cost estimate that is wide of the mark for more unique designs.

Why is that?

Simply because there is much more that needs to be factored in before you can get a more accurate new double glazing windows cost. Not only that, but the effects of the COVID-19 pandemic have changed how much new windows cost throughout the UK. As a result, it’s more important than ever to do the proper research to get the best possible average price for new windows.

Let’s take a look at some of the factors that would affect the average price for new windows. And, at Double Glazing on the Web, we can help you lower your average price for new windows as well.

average price of new windows

The average price for new windows depends on a number of factors, such as style, size, material and even location.

To find out how much your new windows will cost, you’ll need to take these factors into consideration when looking for window quotes.

How Much Does It Cost to Replace Windows?

Your new windows will cost what they do depending on how many windows you want to replace and what you want to replace them with.

The average price for installing new windows does not have to include dismantling and disposal of old windows.

When replacing your windows, the average price for new windows may also vary from installer to installer. A small local establishment might offer new windows that cost £50 per window, but the same new windows might cost you around £75 with a large national installer.

How Does The Location Affect The Average Price For New Windows?

When getting a quote for the average price for new windows, you also need to include the location your new windows will go in.

Why is that?

It’s because the location of the windows makes a difference to how much your new windows cost. If the windows are not on the ground floor, or not accessible easily from the ground, the installation would require scaffolding. The scaffolding and setting it up would cost extra, and will make your new windows cost more to fit.

How much of a difference to the average price for new windows does the floor you fit them on make? Let’s compare:

New 60cm x 90cm uPVC windows on the ground floor cost between £500 to £570 to buy and install. However, the same new windows on the second floor cost £560 to £625 to buy and install.

New aluminium windows of the same size cost between £540 and £605 to buy and install on the ground floor. And, on the second floor, the average price for new windows and installation can cost between £605 and £680.

An average price for new windows with wooden frames will have an even higher cost. On the ground floor, the average price for new windows would cost you between £845 to £910 to install a window. But again, on the second floor, you can expect the average price for new windows and installation to have a higher cost of between £900 to £970.

Window Styles: Average Price For New Windows

The average price for new windows we’ve shown you are based on casement windows. Casement windows are the most basic window style, and are the most popular in the UK. These are single or double-door windows that swing open outwards on hinges attached to the side of the frame.

Since these are the most basic design, that gives them the most affordable new windows cost.

New 100cm x 100cm uPVC casement windows can cost £325 to begin with, going up to £420 with a complete installation. The average price for new windows in the casement style has a cost between £500 and £1230.

The average price for new sash windows, on the other hand, is a higher cost. Sash windows are windows that slide upwards or downwards to open. For a double glazed sash window of the same size, 100cm x 100cm, and same material, uPVC, the average price for new windows would cost from £640 and go up to £820. New sash windows are estimated to cost around 75% more than the equivalent casement windows.

New tilt and turn windows, while not as expensive as sash, cost more than casement designs. These windows that are tilted to open are good for places where you need to control the amount of ventilation. New 100cm x 100cm double glazed tilt and turn windows with uPVC frames would cost £490 and could go up to £625. New tilt and turn windows have a higher average price for new windows than casement designs as well

New 100cm x 100cm dual turn windows can make your new windows cost more than tilt and turn but less than sash windows. New double glazed dual turn windows cost from £525 and go up to £670. Dual turn windows have similar prices to tilt and turn windows.

The average price for new windows is also dependent on their size. A casement window of 100cm x 100cm is more expensive than that of 50cm x 50cm. The smaller sizes of new windows cost around £275 and go up to £360.

The rule of the thumb is that the larger the size of the window, the more your new windows will cost.

How Does Glass Type And Design Affect the Average Price for New Windows?

Did you know that if your window is 800mm or less from the floor, it needs to have toughened glass installed instead of regular glass? Toughened glass is heat-treated, meaning it can shatter into crystals when it breaks. It is much safer than regular glass, which can break into far more dangerous shards. Not only that, it’ll affect how much your new windows cost.

How much will this affect your average price for new windows? Toughened glass can add around 20% to your new windows cost. Even if you are not using toughened glass, simple design features like Georgian bars and lead designs will add a minimum of £30 to how much your new windows will cost.

How Much Do New Windows Cost With Different Frames?

The window style and size are not the only consideration when you are looking for how much your new double glazed windows will cost. Another very important factor when calculating the average price for new windows is the material of the frame. Since frames can determine the appearance of your new windows design, they are quite important for determining how much your new windows will cost.

Frames for double glazed windows come in three materials in the UK. These are Wooden, Aluminium, and uPVC. Of the three, uPVC is the most commonly used, and makes new windows cost the least. Its popularity in new windows can be attributed to its multiple advantages over the other two.

What Benefits do the Three Materials Offer?

  • Lightweight: Both aluminium and uPVC are light materials. Wood, on the other hand, is heavy.
  • Maintenance: uPVC requires little by way of maintenance as does aluminium. Wood requires the most effort in upkeep.
  • Durability: All three materials are very durable. However, wooden frames need a lot of work in order to make them last long. The cost and effort of upkeep can affect how much your new windows will cost over time, helping you get a better idea of your expenses.
  • Energy-efficiency: uPVC and wood are highly energy-efficient.
  • Appearance: Of the three types, wooden frames look the best. They look natural and give the house an everlasting appeal. In comparison, uPVC and aluminium don’t give that same appearance.

However, since both materials come in many different colours, it is possible to customise the appearance of both to suit your sense of aesthetics. When finding out the average price for new windows, you should know that wood and aluminium cost about 30% and 50% more than uPVC.

So, if you’re installing new windows a small flat with 4 windows, the average price for new windows will cost around £2,140, complete with installation. The same set-up with aluminium frames would cost £2,288 with installation. With wooden frames, however, the average price for new windows could cost as high as £3,508.

These prices are for frames with basic finishes. So, if you’re looking for custom colours and finishes, that could increase the average price for new windows. You can buy new windows with aluminium and uPVC frames in wood finishes, but these new windows cost more.

Get The Best Average Price For New Windows

The best way to get the average price for new windows and to cut the cost is to shop around before making a purchase. Our recommendation would be to get quotes from at least three different suppliers to find out how much new windows cost. You should also get quotes from installers to find the average price for new windows near you.

Most suppliers would be happy to recommend reputed local installers, or you could choose to go with a national installer. However, the local company should offer new windows that cost less, and you might not have to wait or have a minimum order. You may even ask to see their work as it will be local.

You would need to ensure they are certified and will give you the best possible service, though. If you would rather not risk it, go with a national company. They will have all the certifications and standardised services that you don’t need to worry about, although they often charge a higher new windows cost.

Finding out how much your new windows will cost is not as difficult as you might have initially believed. It is simply a matter of identifying exactly what you want and finding the right suppliers for it. Go about it wisely, and you will end up with the perfect average price for new windows in your house.
