How much does it cost to replace windows?

New windows in the UK will come with double glazing as standard. When deciding on new windows, your choice of window material can have a significant bearing on the total double glazing cost. The most popular materials include uPVC, aluminium, and timber. 

For extra security, noise reduction, and thermal efficiency, some people opt for triple glazed windows. Triple glazing costs are usually 30-40% higher than standard double glazing. Considering the extra cost, triple glazing is only recommended for households in especially cold climates that can make the best use of the extra benefits. 

Considering all the available window styles, we’ve put together the average new window prices according to the material you choose, as shown below. 

If window replacement costs are well beyond your budget, then some companies can offer windows on finance. This gives you the chance to pay for your windows in pre-agreed instalments.

Which are the cheapest window frames?

The cheapest windows available in the UK are uPVC windows, making them one of the most popular options available on the market today. 

Aluminium can be significantly more expensive than uPVC with prices usually starting at 30-40% higher, while timber prices usually start at 50-60% higher than uPVC, depending on the style and size of the window. 

uPVC window prices

uPVC window prices in the UK range from £160 – £1,240, before installation. This price range accounts for casement, tilt and turn, and sash windows in various standard sizes. 

uPVC casement window cost

uPVC£160 – £990£200 – £1,065£230 – £1,240

While uPVC is appealing for its affordable prices, the cheapest options out there might be more susceptible to warping over time. High-quality uPVC, however, is highly durable, weather-proof, and energy efficient. 

These windows also require little to no maintenance across their lifetimes, besides the occasional wipe-down with a damp cloth. 

Aluminium window prices

New aluminium window prices in the UK typically fall between £210 – £1,615 including standard-sized casement, tilt and turn, and sash windows. This does not include installation costs.

Aluminium£210 – £1,290£260 – £1,390£300 – £1,615

While aluminium windows are considerably more expensive than uPVC, these windows are highly durable, long-lasting and much sought after for their stylish appearance. With modern thermal break technology, aluminium can also provide excellent thermal efficiency and requires very little maintenance over its long lifespan. 

Timber window prices

Timber casement, tilt and turn and sash window prices in the UK tend to range between £240 – £1,860 before installation. Timber windows come available as softwoods or hardwoods, in a range of standard sizes. 

Timber casement window cost

Timber£240 – £1,485£300 – £1,600£345 – £1,860

Wooden window costs are the most the highest compared to other materials, since they will last longer than any other material, and are the most thermally efficient. With much aesthetic beauty and customisable options, timber windows can also become the focal point of any home. 

One downside to these windows is their regular maintenance. To prevent rotting and weather warping, you should repaint or re-varnish a wooden every 1-5 years. 

While the upfront price for some new wooden windows can demand a lot from your wallet, you can at least rest assured that you’ll receive a good deal on installation. You can do this by getting your quotes from Household Quotes.

Which is the cheapest style of window?

The cheapest style of window you could buy today is a casement window in uPVC. Fixed casement windows require far less hardware since they do not open, making them the most affordable type of window. Single and double casements are priced slightly higher, yet fall lower than most other window types (tilt and turn and sash windows).

Casement windows prices

Casement windows are priced between £160 – £1,240 in the UK, not including installation costs. Casement windows can be seen everywhere in the UK. They are simple to operate, versatile and relatively more affordable than most other window types, whichever material you use.

Casement window costs
Window Frame600 x 900mm900 x 1200mm1400 x 1400mm
uPVC£160 – £660£200 – £710£230 – £825

Timber£240 – £990£300 – £1,065£345 – £1,240
Casement window costs

Typically, casement windows open from a side-mounted hinge which allows them to swing open fully. This lets in plenty of ventilation throughout your home and allows easy access to both sides for cleaning. Casement windows can also open from a top hinge. In this case, they are known as top-hung windows. They also commonly come as double casements, which feature two windows, separated by a central mullion. 

Tilt And turn windows prices

Tilt and turn windows typically cost between £200 – £1,550, not including installation. While they are slightly more expensive than casement windows, they allow more options in terms of how they operate. This helps improve ventilation through your home while maintaining comfortable levels of security and safety. 

Tilt and turn windows
Window Frame600 x 900mm900 x 1200mm1400 x 1400mm
uPVC£200 – £825£250 – £890£290 – £1,030

Timber£300 – £1,240£375 – £1,330£430 – £1,550
Tilt and turn windows

Tilt and turn windows are highly versatile in that you have the option to open them fully like a casement window, or they can tilt open from the top of the window. If you’d like fresh air to enter your home while you’re not around, then the tilt-open function allows ventilation while the opening is too small for anyone to enter. An in-swing tilt and turn window also allows easy access to both sides of the window for easy cleaning and maintenance. 

Sash windows prices

In the UK, sash windows typically cost between £240 – £1,860, not including installation. These are one of the more expensive window types given since they are associated with traditional British heritage architecture and they usually feature an intricate design and glazing pattern. Wooden sash window costs are some of the most expensive single window units on the market. 

Sash windows
Window Frame600 x 900mm900 x 1200mm1400 x 1400mm
uPVC£240 – £990£300 – £1,065£345 – £1,240

Timber£360 – £1,485£450 – £1,600£520 – £1,860
Sash window costs

Sash windows can become the focal point of any home given their distinct design and historic significance. They best complement cottage-style homes, or grand city homes. A sash window will typically feature two panels, one of which can slide vertically over the other. In a double-hung window, both windows are fully openable, allowing for even more ventilation. Modern sash windows can be turned to lie horizontally which allows for easier access to both sides of the window for cleaning. 

Bay windows prices

Bay windows costs will usually fall between £1,190 – £2,700, before installation. They are considerably more expensive than standard window types, given that they are made up of 3 window units.

Bay windows (3 panels)

Timber£1,785 – £2,590£1,860 – £2,700
Bay window prices

A bay window extends from the side of your property to form a curved window structure. They have a grand appearance since they can make your home seem larger. From the inside, you are also granted some extra living space in the curve of the window. You can choose any of the standard window types to fit into a bay window structure. Whichever you choose, you can enjoy lots more natural light and ventilation in your home. 

Bow windows prices

Bow windows in the UK can fall anywhere between £1,430 – £5,485, before installation. The cost depends on how many panels you’d like to feature. Companies will usually offer between 4-6 panels.

bow window prices

Bow windows consist of multiple panels which make up a bow-shaped curve from the side of your building. Often this creates a wide panoramic view to the outside and opens up the space in your home. Like bay windows, bow windows also create some extra indoor living space, which you could transform into a seating area. 

Whichever style of window you choose, you want to be sure that you find a reputable installer that is up to the job. You can either spend countless hours researching installers or you can leave it to our team at Household Quotes to find the best installers for your particular project.

How To Measure Your Windows

When it comes to window replacement, measuring your existing windows is an essential step to make sure your new windows can fit within the existing opening. Failing to do this, or measuring incorrectly, will add to the overall time and costs of your window replacement. 

How to measure your windows

It’s best to consult a professional installer who can do the measurements for you, which most companies will offer free of charge.

Secondary glazing VS double glazing

There are many reasons why you might prefer secondary glazing over double glazing. Secondary glazing usually takes the form of an additional framed panel attached to the inside of your window to provide an extra layer of insulation. Other types of secondary glazing include glazing film or magnetic glazing panels. 

Secondary glazing costs fall considerably lower than double glazing, as well as offering a non-permanent alternative to double glazing. While it doesn’t offer the same levels of thermal efficiency or soundproofing, it will certainly improve the performance of outdated or single glazed windows. 

Those living in heritage buildings or listed properties may not be allowed to replace their windows, or the glazing in their windows so that the original appearance of the building is maintained. In this case, secondary glazing becomes the best option for improving energy efficiency and preventing heat loss. 

Secondary glazing vs double glazing

How do you know when it’s time to replace your windows?

Even the best-performing windows will eventually need to be replaced, although some windows can last as long as 50 years. The lifespan of a window depends on the frame material and how well they are installed and maintained. 

Outdated or damaged windows can impact the comfort and security of your home. You may also notice your energy bills go up as a result. Single glazed windows are also worth considering for replacement. Even if the window is in good condition, single glazing simply can’t perform at the same level as double or triple glazed windows, which are reinforced with 1-2 more panels of glass. 

Here are some of the most clear signs that your window might be in need of a replacement: 

Get the best window quotes and prices for your household

When it comes to installation of your replacement windows, you can save money by collecting multiple quotes from at least 3 installation companies. You can then compare their quotes and choose the installer that offers the best deal. 

Remember: the best quotes don’t always come from the installers that offer the cheapest rates. You should always lean on the side of caution when considering an especially low price for installation, as it could indicate that the installer is inexperienced or less interested in doing a good job. 

A quality installer will have a proven track record of their previous work, with plenty of positive customer reviews and testimonials. Their window products should also come with a lengthy warranty or guarantee (at least 5 years). 

What should a quote for new windows include?

A new window quote should include the total price for the installation of your new windows. If you are getting your windows supplied by the same company, then it should also include the cost of the window units themselves. 

Window quotes should also offer an itemised list that breaks down the price of parts and labour associated with the installation job. This will usually include things like labour costs, additional hardware, and glazing costs. You can always request an installer to break down their costs into an itemised list if they don’t initially provide it. 

In most cases, window installation quotes are fixed. Should any issues come up during the installation that add to the overall time, or that require additional parts and labour, then the total price might increase. The installer should always make you aware of any changes in the price beforehand. 

To get a competitively priced quote from some of the top-rated installers in your area, don’t spend countless hours of tiresome research, instead, get your quotes from Household Quotes. 

We can match you with up to 4 of the best local installers from our extensive network. All of our installers have been individually vetted by our team, so you can rest assured that we only match you with the most reputable options in your area.
