Understanding replacement window prices requires consideration of various factors, such as type, frame material, colour, and size.
Different window types have varying costs, ranging from budget-friendly casement windows to more expensive sash and tilt & turn windows.
New windows cost anything between £550 and £3,600 per window, depending on the options chosen, size, and the number you order. uPVC casement windows are the most cost-effective option, costing between £550 to £1,900 depending on size, glazing, and volume to be replaced.

| Window Type | Cost |
| UPVC Window | £200 |
| Aluminium Window | £300 |
| Timber Window | £350 |
Window prices aren’t uniform; they’re shaped by a variety of factors, including:
- The type of window
- Frame material
- Size
- Colour
- Customization options
Imagine a broad spectrum: at one end, you have casement windows, known for their affordability, while at the other, you encounter sash or bay windows. Replacing windows of these styles is pricier due to their intricate design and operation.
Now, factor in the frame material – whether uPVC, aluminium, or timber – each with its cost implications.
Consider the size, colour, and customisation options, and you’ll find a diverse price range as varied as the windows themselves, making it challenging to pinpoint the expected cost of window replacement for your property.

Dimension, colour, and personalisation
The appeal of personalisation lies in its ability to infuse your windows with unique touches. Yet, it’s crucial to note that these personalised additions can impact the overall cost.
Typically, standard window sizes come with predictable prices, but venturing into non-standard dimensions might inflate your expenses.
Likewise, while white uPVC remains the conventional choice, selecting a woodgrain effect or a vibrant colour can elevate the visual appeal of your windows, albeit potentially raising your invoice as well.
Costs of Window Frame Materials
Much like a picture frame enhances an image, the material of your window frame can elevate both the appearance and performance of your windows.
Frames crafted from uPVC are favoured for their economical nature, providing durability, low maintenance, and superior insulation, albeit at a cost.
However, if you’re inclined to splurge for a contemporary, streamlined aesthetic, aluminium frames could be the perfect fit.
For those with the timeless elegance and innate warmth of wood, timber frames are an option, albeit with a premium price tag.
The Typical Cost of Window Replacement in 2024
Having delved into the various influences on window prices, let’s now focus on the bottom line – quite literally. On average, replacing windows comes to around £4,500 for a 3-bedroom house, VAT included.
However, it’s important to note that this is merely an average. Your actual expenses might be lower if you opt for uPVC casement windows in a modest terrace house, or they could be higher if you choose wooden sash windows for a spacious, detached property.
uPVC windows tend to be more budget-friendly compared to other materials, with casement windows representing the most economical option.
This estimate encompasses all additional factors, such as installation expenses, material quality, and any specific requirements that could sway your final cost in either direction.
For households with limited incomes, there are government-sponsored window grants available to assist with the installation of new windows in homes and properties.
Pricing of uPVC Windows Across Various Styles
For individuals aiming to strike a balance between affordability and functionality, uPVC windows stand out as a popular choice. However, even within this realm of budget-friendly options, prices may fluctuate based on the window’s style.
Let’s delve deeper into the cost breakdown of uPVC windows for different styles.
Casement Windows: The Economical Choice in uPVC
Casement windows stand as the budget-friendly champions within the realm of uPVC.
Operated effortlessly with a basic handle, these windows are favoured for their affordability.
Yet, their simplicity doesn’t detract from their performance. They’re versatile, convenient, and ensure excellent ventilation.
Moreover, they offer an uninterrupted view thanks to the absence of a central rail.
When closed, they form a secure seal, bolstering both security and energy efficiency.
Sash Windows: The Aesthetic Icons
While casement windows reign supreme in affordability, sash windows excel in aesthetics.
Featuring a vertical sliding mechanism, sash windows infuse homes with a sense of elegance and timeless charm.
Yet, this beauty comes with a cost. On average, sash windows are 50% pricier than their casement counterparts.
However, for those who prioritise aesthetics, the additional expense of sash windows may be justified. Explore our guide on the costs of uPVC sash windows here.
Tilt-and-Turn Windows
Tilt-and-turn windows provide a fusion of functionality and style. Their dual opening mechanism allows for both inward tilting from the top and turning via the handle.
This versatility ensures optimal ventilation and facilitates easy cleaning.
However, this multifaceted design comes with a premium price tag. Tilt-and-turn windows typically cost 25% more than casement windows.
What is the Cost of 2 uPVC Windows?
For a pair of average-sized uPVC windows, anticipate spending approximately £400 solely for the windows themselves. Purchasing in larger quantities might qualify you for a discount on your new uPVC windows. Consequently, a set of 8 uPVC windows will average around £1,500, excluding installation costs.

Aluminium Windows Costs
Ascending the cost hierarchy, we encounter aluminium windows, which are pricier compared to uPVC.
Featuring a casement aluminium window frame material, they boast a sleek, contemporary appearance. While their price surpasses that of uPVC windows, they present a distinctive array of benefits.
Aluminium windows are renowned for their durability and modern aesthetic appeal.
Additionally, they offer enhanced thermal efficiency in comparison to uPVC, potentially resulting in long-term savings on energy expenses, despite the initial higher cost of aluminium windows.
Opting for aluminium windows is an excellent decision for those seeking to upgrade to a modern aesthetic while improving energy efficiency.
Wooden Frame Windows Costs
At the pinnacle of the price spectrum, wooden frame windows reign supreme. These timber windows offer a classic, refined aesthetic and have the potential to substantially enhance a property’s value.
However, they come with a hefty price tag attributed to the material’s inherent appeal and the craftsmanship involved in crafting the frames. Wooden frames generally incur costs that are 50% higher than uPVC.
Nevertheless, for those prepared to make the investment, wooden windows present a durable, visually appealing solution that stands the test of time.
Individual Window Cost
The cost of a single window can fluctuate significantly, contingent upon factors such as the window type, frame material, and size.
For instance, a solitary uPVC casement window could range from approximately £500 to £1,800, depending on the particular features you select.
Keep in mind, acquiring a new window entails more than simply plugging a gap in the wall; it involves selecting from a range of window styles that complement your home, materials that deliver optimal performance, and a size that aligns with your space.
Dual Window Costs
You may encounter some economies of scale when considering dual windows, which consist of two units joined together, providing potential cost savings when bought in larger quantities.
The pricing will be influenced by the window type and frame material, and the quantity required will also impact the total expense.
While there might be savings in the per-window cost, it’s essential to note that dual windows are larger and might entail a more intricate installation process, potentially contributing to higher overall costs.
