Understanding Window Prices and Factors to Consider

Here is a quick overview of how much a single casement window in the main materials will cost, not including fitting charges:

Type Cost
uPVC Window £200
Aluminium Window £300
Timber Window £350


Window prices are not a one-size-fits-all affair. They are influenced by a medley of factors, including:

  • The window type
  • Frame material
  • Size
  • Colour
  • Customisation options

Picture a wide spectrum: on one end, you have casement windows, recognised for their cost-effectiveness, while on the other end, you find sash or bay windows. 

Replacing windows for these styles costs more due to their intricate design and operation.

Now, blend in the frame material - uPVC, aluminium, or timber - each with cost implications.

Add a dash of size, colour, and customisation, and you have a price range as diverse as the windows, making it hard to quickly say the price you can expect on how much to replace windows in your property will cost.

Average Cost of New Windows in the UK

How much does it cost to replace windows? This depends on the type, which we will cover below.

We will examine the average cost of casement windows, sash windows, and tilt-and-turn windows.

As an overview:

  1. Casement windows, are hinged on one side and open outward. They are versatile and easy to clean.
  2. Sash windows, known for their vertical sliding operation, offer a classic charm but come with a higher price tag.
  3. Tilt and turn windows blend functionality and style but with a price scale tipping towards the higher end.
Style Cost
Casement Window £200
Sash Window £400
Tilt and Turn Window £500


The key lies in balancing your aesthetic preferences, functional requirements, and budget constraints.

Frame materials costs

Just as a picture frame enhances an image, the material of your window frame can improve your windows' appearance and performance.

Window frames made from uPVC are the economical crowd-pleasers, offering durability, minimal maintenance, and excellent insulation, albeit with an impact on the cost.

But if you’re willing to stretch your budget for a sleek, modern look, aluminium frames might be your match.

Timber frames are available for those drawn to wood's timeless elegance and natural warmth, though they come with a price premium.

Size, colour and customisation

The beauty of customisation is that it allows you to add personal touches to your windows. However, it’s important to remember that these individual touches can affect the total cost.

Standard window sizes usually come with average prices, but going off the beaten path with non-standard sizes might add to your costs.

Similarly, while white uPVC is the standard colour, opting for a woodgrain effect or a bold colour can make your windows stand out, but it could also make your bill stand out.

The Average Window Replacement Cost in 2024

Now that we’ve discussed the factors influencing window prices, let’s bring it home - literally. On average, replacement windows cost approximately £4,500 for a 3-bedroom house, including VAT.

But remember, this is an average. Your actual cost could be less if you opt for uPVC casement windows in a small terrace house or more if you go for wooden sash windows in a large, detached property.

uPVC windows cost less than other materials and casement windows are the cheapest option too.

This includes all the additional factors like installation costs, quality of materials, and any specific requirements that can steer your final cost in either direction.

For low income households, there are window grants put in place by the government that can help fund new windows being installed in houses and properties.

UPVC Window Prices for Different Styles of Windows

For those seeking a balance between cost-effectiveness and performance, uPVC windows are popular. But even within this budget-friendly realm, prices can vary depending on the style of the window.

Let’s look closer at the pricing of uPVC windows for different styles.

Casement windows

Casement windows are the cost-effective champions of the uPVC world.

These windows, operated with a simple handle, are a favourite for their affordability.

White uPVC Casement Window

However, their simplicity does not compromise their performance. They’re versatile, convenient, and offer optimal ventilation.

On top of that, they provide an unobstructed view since there’s no central rail.

They form a secure seal when closed, enhancing security and energy efficiency.

Sash windows

If casement windows are the cost-effective champions, sash windows are the aesthetic aces.

Sash windows, characterised by their vertical sliding operation, add a touch of elegance and classic charm to any home.

However, this beauty comes at a price. On average, sash windows are 50% more expensive than their casement counterparts.

But for those who value aesthetics, the additional cost of a sash window might be worth paying. View our guide on uPVC sash window costs here.

Tilt and turn windows

Tilt-and-turn windows offer the best of both worlds - functionality and style. They can be opened in two ways: inwardly by tilting the top of the window or by turning the handle.

This dual function offers excellent ventilation and ease of cleaning.

However, this versatility comes with a higher price tag, with tilt and turn windows being 25% more expensive than casement windows.

How much do 2 UPVC windows cost?

If you are looking for 2 UPVC windows of average sized then expect to pay around £400 just for the windows on their own. If you are buying in bulk, you may be able to get a discount on your new UPVC windows. Therefore, 8 UPVC windows will cost around £1,500 on average without installation.

See our quick table below for more information on multiple windows and their average prices.

Number of UPVC windows* Average Cost
1 £200
2 £400
3 £600
4 £800
5 £1,000
6 £1,200
7 £1,350
8 £1,500
9 £1,650
10 £1,800
11 £1,950

Aluminium window prices

Stepping up the price ladder, we find aluminium windows more expensive than uPVC.

This casement aluminium window frame material offers a sleek, modern look, and while they are more expensive than uPVC windows, they offer a unique set of advantages.

Aluminium windows are known for their durability and modern aesthetic.

They also offer improved thermal efficiency compared to uPVC, which can lead to long-term savings on energy costs, even though the initial cost of aluminium windows may be higher than others.

Aluminium windows are an excellent choice to replace windows for a modern look and improved energy efficiency.

Wooden frame window prices

At the top of the price scale, we find wooden frame windows. These timber windows provide a traditional, elegant appearance and can add significant value to a property.

However, they come with a higher price tag due to the material’s natural appeal and the craftsmanship required to create the frames. Wooden frames typically cost 50% more than uPVC.

But for those willing to invest, wooden windows can offer a long-lasting, aesthetically pleasing solution.

Single window price

The price for a single window can vary widely, depending on factors like the window type, frame material, and size.

For example, a single uPVC casement window might cost you in the ballpark of £500 to £1,800, depending on the specific features you opt for.

Remember, getting a new window isn’t just about filling a hole in the wall - it’s about choosing from various window styles that fit your home, materials that offer the best performance, and a size that suits your space.

Double windows prices

You might find some economies of scale at play regarding double windows, which are two joined together, offering cost savings when purchased in larger quantities.

The price will depend on the window type and frame material; how many windows you need will also influence the overall cost.

While you might save on the per-window cost, remember that double windows are more extensive and may require a more complex installation process, which could add to the overall costs.

Bay window price

With their charming alcoves and generous natural light, bay windows are a dream feature for many homeowners. However, they come with a higher price tag due to their larger size and more complex installation process.

For those willing to invest, even though a bay window cost more, it can add significant value to a property in terms of aesthetics and potential resale value.

Bay windows can be a great addition to any home, providing a unique look and feel.

Leaded window price

With their intricate designs and vintage charm, leaded windows can add a unique touch to your home. But this uniqueness comes with a price.

The cost of leaded windows can vary greatly depending on the complexity of the design and the materials used.

However, leaded windows can be an excellent choice for those who value individuality and are willing to invest in it.

Energy Efficiency and Savings

One of the most compelling reasons to invest in new windows is the potential energy savings.

New windows, particularly those with double or triple glazing, can significantly improve your home's insulation, helping to keep heat in during the winter and out during the summer.

It will also help to prevent condensation on your windows, which can damage them over time if nothing is done about it.

If your windows continue to gain condensation and damage over time, you could end up with leaking windows.

This makes your home more comfortable and can result in significant savings on heating and cooling bills.

Noise Reduction

In an increasingly noisy world, the ability of new double-glazed windows to reduce noise can be a significant boon.

A double-glazed window, featuring double glazing, can significantly reduce the noise entering your home from the outside, providing a quieter and more peaceful living environment.

Whether you live by a busy road or value your quiet time, noise reduction significantly benefits new windows.

Features like toughened glass, multi-point locking systems, and robust frames can make it much harder for potential intruders to access your home.

So, while new windows might seem like a significant investment, considering their cost, they can also provide invaluable peace of mind.

Triple Glazing Windows vs Double Glazed Windows

As you navigate the world of window prices, you may find yourself weighing up the pros and cons of double-glazed windows vs triple-glazing.

While triple glazing does offer better insulation and noise reduction, it also comes with a higher price tag.

So, is it worth the extra investment, or should you consider the double glazing cost instead? To make an informed decision, try using a double-glazing cost calculator to compare the expenses.

The answer will depend on factors like your budget, energy usage, and the noise level in your environment.

While double glazing prices are cheaper, understanding the differences can help you make an informed decision that’s right for your home.

Replacing Existing Windows vs Installing New Windows

When upgrading your windows, you might be wondering whether it’s more cost-effective to replace your existing windows or install replacement windows.

However, installing new windows may be a better option if you’re looking for a significant upgrade in energy efficiency or aesthetics.

Understanding the costs and benefits of replacing windows or getting new ones can help you make the best decision for your home and your budget.

How to Choose the Right Window Installer

Choosing the right window installer can be just as important as choosing the right windows.

After all, even the best windows won’t perform well if they’re not installed correctly.

When looking for a window installer, comparing quotes, checking for certifications, and reading reviews is essential.

Remember, the cheapest quote might not necessarily be the best - you want an installer who will do a good job, not just a cheap one.

Understanding Quotes and Comparing Prices

You’ll likely be faced with various quotes from different suppliers in your quest for new windows.

Understanding these quotes and how to compare them is crucial to ensuring you get the best deal.

Be sure to look at more than just the bottom-line price - consider things like the quality of the windows, the cost of installation, and any additional services that are included.

And remember, the cheapest quote might not necessarily offer the best value. It’s important to weigh up all the factors before making a decision. Make sure you check your computer.
