How Much Do New Windows Cost in the UK? (2024)

Windows are an essential part of a household, given their enormous impact on energy bills, insulation, and home lighting. So, how much are windows in the UK? A single window can cost between £160 and £1,860, but this can vary based on numerous factors such as size, material, glazing type, style, and installation complexity.

For instance, the average cost of new windows for a 3 bed house in the UK can be between £1,600 and £17,250 if it requires 8-10 uPVC windows. The table below shows how much windows cost in the UK per material type for a single window in 2024.

To ensure you get the best value for your window installation project, remember that costs are primarily determined by the size, style, and material of your chosen windows, as well as the installation rates of different companies. How much new windows cost can also vary based on the installer as well.

Finding prices for a window replacement can also be difficult due to variables like size and materials. The table above shows the average cost per double glazed window depending on the type of frame material you choose and the size of the window.

Installing double glazing with uPVC frames throughout an average 3 bedroom house could cost between £1,200 to £12,400. The average triple glazing cost will be around 40% above double glazing and opting for aluminium or timber frames will be more expensive again, adding between 30-50% to the price.

So, how much are new windows for different house sizes? The average cost of new windows for a 3 bed house (the average home size in the UK) is between £4,000 and £16,500 for 8 to 10 windows. Similarly, the average cost of new windows for a 2 bed house in the UK can range from £1,800 to £8,775, while the average cost of new windows for a 4 bed house in the UK can be £2,400 to £38,850.

uPVC window frames are generally the lowest-cost option. Composite windows (a combination of timber and aluminium or steel) are often the most expensive type of frame to install. In terms of design, picture window costs are usually lower, whereas sash windows are often the most expensive to install. The more complicated and security-enhanced the window opening is, the more expensive the window becomes.

There are numerous incentives and window grants available that help improve your home. Among these ECO4, Warmer Homes Scotland, and Home Upgrade Grant are the most popular. Most of these are means-tested to help out the homes that need them the most.

They can potentially offset your installation and reduce how much new windows cost for your home. Grants like ECO4 and the Affordable Warmth Scheme can cover the entire cost of new windows if you are on benefits or meet the income threshold set by the government.

Similarly, Home Energy Scotland Grant & Loan can replace single glazed windows but does not offer loans for improving existing double or triple glazing. At the same time, as of August 2024, applicants must live in an already existing building, as the scheme is no longer available to homeowners building their own homes.

It’s best to check with your local installers and authorities to see if you can qualify for any grants. If grants don't apply, there are still many windows finance schemes that make your installation cheaper.

The material you choose for your window frames will significantly impact the cost. We’ve put together some average prices for the supply and installation of windows by material to give you an indication of the price difference you are looking at.

uPVC windows are generally the lowest cost option, but this doesn’t necessarily mean they’re the lesser option. Despite having lower energy efficiency than aluminium and timber, they can still be a sustainable option that decreases energy bills and your home’s carbon footprint.

High-quality uPVC frames are highly thermally efficient and long-lasting. They are also easy to maintain, requiring only an occasional wipe down. However, poor quality uPVC can warp over time, so cheaper models may not be the best long-term investment for your home.

Aluminium windows are more expensive than uPVC, but they will provide your home with long-lasting, durable, sleek-looking windows with an energy-efficient design. They offer high energy efficiency, especially when fitted with thermal break technology. They also have slimmer frames and require less maintenance than timber.

Timber or wooden windows are the most costly option but can add real value to your home, especially if you are conscious about the overall aesthetics. Timber windows provide a classic and elegant finish and are perfect if your home is of a particular period. It is possible to find cheap wooden windows online, although the quality will vary. Timber can also allow for better noise reduction.

It’s worth remembering that, in addition to higher costs, they also require more ongoing maintenance than uPVC or aluminium. On the other hand, wooden windows can last literally a lifetime, so they can be worth more than the cost of replacing windows in the UK.

uPVC casement windows are the cheapest type of window. The lowest window replacement cost will also depend on size, with 600 x 900mm being as low as £160.

Double glazed sash windows cost between £240 and £1,860, being more expensive than casement windows. They can be a good option for classical homes and conservation areas.

Tilt and Turn windows are a more modern solution as, unlike other types, they open inwards into the room so it’s easier to maintain them and ventilation is improved. The tilting feature also means that you have a great deal of flexibility when it comes to how widely you open them.

Bow windows are a type of bay window that curves and adds a rounded aesthetic to the exterior of your home. They are a great option if maximising light in your home is a priority.

Where possible you will need to measure the aperture or brickwork opening on the outside of your property. You should also measure the height and width from three different places - the left side, right side, and centre. Then, use the smallest measurement for both dimensions to account for any natural expansion from hot weather.

Any windows above the ground floor will cost more to replace as the window fitter will need to use scaffolding to access them. It’s possible that a company may offer a discount if you need more than 5 windows. Not sure how to measure your windows correctly? Take a look at our step-by-step guide on how to measure windows for replacement.

The table below shows standard sizes for windows in the UK. 

Double glazing prices sit at around £160 – £1,860 per window. However, double glazing prices will vary from installation to installation. Triple glazing can be 30% to 50% more expensive than double glazing. Secondary glazing can be the cheapest option but it has roughly half the energy efficiency of double glazing.

As an effective insulator, double glazing will help keep your home warmer and reduce outdoor noise, being well worth the investment. The Energy Saving Trust found that gas heated homes across England, Scotland and Wales could save up to £140 a year.

While triple glazing can be effective against the cold, it may not add value to certain homes. The increased cost may not be worth it if you do not live in a region cold enough. It’s best to ask a reliable installer whether your home will benefit significantly from it.

If the cost of double or triple glazing isn’t a realistic option for you, perhaps because of the costs or because you live in a protected property, then secondary glazing could be the solution. Adding secondary glazing can help you avoid paying the cost of replacement windows in the UK, opting instead for a small layer that covers the window.

Secondary glazing is an excellent solution for heritage buildings with restrictions on altering windows and the exterior appearance. It allows you to enhance your home’s energy efficiency and acoustics without compromising its historical integrity.
