How much should I pay for a new window?

Wondering how much to pay for a new window? You're not alone. Let's look at the average prices in the UK and how they've changed recently.

For a standard uPVC window, expect to pay between £250 and £400. Prefer aluminium or wooden windows? They're a bit pricier, usually around £400 to £700 each. These are just averages, though. The final price can change based on size, style, and extras like double glazing.

Prices have crept up over the past few years. Why? It's down to things like the cost of materials and new, energy-saving window tech. These features might bump up the price, but they can save you money on energy bills in the long run.

Don't forget about the installation costs. They can add £100 to £300 per window, depending on the job's complexity and who does the work.

It’s important to see your new windows as an investment. As well as giving your home an aesthetic spruce-up, replacement windows can improve energy efficiency and your home's value. Our tip? Get a few quotes to compare. The cheapest isn't always the best, especially when it comes to quality and lasting value.


Cost variations: Which factors affect window prices?

We can see that material greatly impacts window costs — in fact, what your window frame is made from may be the biggest factor. Each material has its perks in terms of look and longevity and it’s worth taking into account when comparing your window options.  

  • uPVC windows are your go-to for affordability and low maintenance. They're at the lower end of the price scale. 

  • For a sleek and durable option, you might want to go for aluminium windows, which sit in the mid-range when it comes to window prices.

  • Wooden windows offer classic charm and are usually the most expensive. 

Several other factors come into play, too, each affecting the cost of your new windows. 

Window size

Naturally, the bigger the window, the higher the cost. As well as taking up more materials, larger windows often need extra work to install. A small bathroom window, for example, won't set you back as much as a large bay window.

Glass types and glazing options

Single, double, or triple glazing? The choice impacts both your wallet and your home's energy efficiency. Double glazing is standard for balancing cost and performance. Triple glazing adds more insulation but at a higher price. Special glass types, like noise-reducing or toughened safety glass, also add to the cost.

Finishes and extras

Want a specific colour or finish? Customisation can push up the price. Extras like decorative bars, special handles, or built-in blinds also add to the overall cost.


Longer warranties might come with a higher initial cost. But they offer peace of mind, potentially saving you money on any future repairs.


Where you live can influence the price. Installation costs vary across the UK. In some areas like London, labour is more expensive, which can affect the total cost of your new windows.

How much does window installation cost?

Now you know a little more about window price variations, it’s time to consider installation costs. How much should you set aside for labour?

On average, installation can add £100 to £300 per window to your bill. This varies based on the complexity of the job and the professional you choose. Why does installation cost this much? Well, it's not just about putting the window in place. It involves careful removal of old windows, fitting the new ones correctly, and ensuring everything is sealed and finished properly. Skilled installers will also ensure there's no damage to your home and that the windows function as they should.

Remember, while it might be tempting to save money with a DIY approach, professional installation ensures your windows are fitted safely and efficiently. This can save you money in the long run by avoiding costly mistakes or inefficiencies.

Can new windows add value to my property?

This is a worthwhile query and one that many homeowners ponder, especially when considering home improvements. Fortunately, the answer is quite encouraging.

In short, new windows are a smart investment with several tangible benefits.

Kerb appeal

First off, they significantly boost your property's kerb appeal. Think about the impact of replacing old, worn-out windows with sleek, new ones. When you’re putting your house or flat up for sale, it’s essential to make a good first impression. Buyers will appreciate windows that will welcome guests and visitors, and most importantly, keep them cosy!

Energy efficiency

In today's market, buyers are increasingly aware of energy costs. New windows, especially those double or triple-glazed designs, help maintain a comfortable indoor temperature year-round. This leads to lower energy bills — a key selling point for potential buyers. Better energy efficiency brings both savings and comfort.

Noise reduction

New windows can dramatically decrease external noise, a feature that's highly valued, especially in busy areas. High-quality windows offer the appeal of a quieter, more serene home environment.

Better home security

Improved safety features in modern windows, such as enhanced locks and tougher glass, also add to your home's security, making it more attractive to buyers.

UK grants for new windows

The UK government occasionally provides grants or schemes to assist homeowners in making energy-efficient home improvements — including window upgrades. These grants are designed to encourage energy savings and reduce carbon footprints, aligning with broader environmental goals.

So if you need a helping hand to upgrade your windows, here are some UK window grants you might like to look into:

  • ECO4: As part of the government's initiative to enhance home energy efficiency and combat climate change, this grant provides homeowners with up to £14,000 for installing energy-efficient double glazing.

  • Help2Buy Window Scheme: If you’re an employed, self-employed, or retired homeowner in the UK, you could qualify for this scheme. It provides a range of funding options, allowing eligible homeowners to improve their windows without significant upfront payments.

  • The Affordable Warmth Scheme: Exclusive to Northern Ireland, this window grant provides up to £7,500 to low-income households, focusing on improving insulation and window efficiency. This initiative is designed to make homes warmer and more energy-efficient.


Eligibility for window grants

One key thing to remember is that these grants and schemes can vary in availability and criteria. They might depend on factors like your home's current energy efficiency, your personal circumstances, or the type of property you own. Sometimes, these grants cover a portion of the cost, making the investment in new windows more manageable.

It's also worth noting that your local council might offer additional support or incentives. This can be particularly helpful if you're in a conservation area or a listed building, where window upgrades need to comply with certain standards.
