As you can see, getting double glazed windows pays off, however it’s still important to consider the question “how much does double glazing cost?”.

The average cost of double glazing a 4 bed house can vary widely depending on a number of factors, such as the type of window and whether you decide to go with a local or nationwide installer. It also depends on whether you want the entire window replaced or only the double glazed units.

How much is double glazing for a 4 bed house?

When it comes to figuring out the cost of double glazing a 4 bed house, there’s a few different aspects that can affect the total price point. You’ll need to consider the type of window you want, its size, and the type of material you’d like for the frame. And then of course, you’ll need to multiply this cost by the number of windows you want installed.

In the table below, you can see the average cost of double glazing 1 window with either a uPVC, wood, aluminium, or steel frame.

Average cost of double glazing 1 window*
uPVCWoodAluminium
£635£800£775
*Numbers in the table are for 1 window only (900 x 1200mm)

As you can see, uPVC tends to be the most inexpensive window frame material on the UK market. This, alongside the fact that uPVC is low maintenance compared to some other materials, is why uPVC windows are one of the most popular options in UK homes.

Wooden double glazed windows are also a popular choice, mainly due to their aesthetic appeal. However, you need to keep in mind that some types of wood will be more expensive than others, so you will likely see a large range in prices when considering wooden frames.

Once you’ve considered which frame material you’d like, you need to think about the different styles of windows and which best fit the design of your home. If you live in a historic house then sash windows should complement it well. Whereas, if you live in a more modern home, then casement or tilt & turn windows may be a better fit.

In the following table, you can see the average cost for double glazing 1 window depending on which type of window it is and its frame material.

Average cost of double glazing window type in 4 bed house* 
Window typeuPVCWoodAluminium
Casement£550£640£610
Tilt & turn £680£850£740
Sash£740£1,025£890
Bay£1,460£1,980£1,900
*Numbers in the table are for 1 window only (900 x 1200mm)

uPVC casement windows tend to be the cheapest, hence why you’ll find them in many modern homes. Bay windows, on the other hand, are generally the most expensive regardless of which material is used for the frame.

If you’re interested in the cost of double glazing a 2 bed house (UK) or you want to find out how much does it cost to double glaze a 3 bed house UK, then you can also use the average prices from these two tables above to calculate the cost of double glazing the number of windows in your home.

Whatever type of home you live in, investing in highly efficient double glazed windows will benefit both the value and comfort of your home. However, as you can already see, with the number of window options available, it can be overwhelming to make a choice. On top of that, the prices mentioned in the tables above are only averages, so there are many windows being sold for much higher and lower prices.

Finding and comparing different prices for double glazing all on your own can be tedious and take up hours of your time. Thankfully, we have a solution.

Window Grants in the UK

Window Grants UK

Covering the upfront costs of double glazing, especially when it’s for a 4 bed house with multiple windows, can be pricey. That’s why it’s a good idea to look into grants and see whether anything is available to you.

Currently, the Energy Company Obligation (ECO) is the only option available for covering double glazing costs. This scheme is set to run until the 31st March 2026 and is now in its 4th iteration, referred to as the ECO4. The aim of this scheme is to help support those who are living in fuel poverty and to help reduce the UK’s energy consumption.

Getting double glazed doors and finding the best double glazed windows for your home is seen as one of the top ways to insulate your property and improve its energy efficiency. Therefore, costs for this insulation method are covered by the ECO4 scheme. Furthermore, the efficiency of double glazing will also help reduce your heating bills and carbon emissions.

In order to receive the ECO4 grant, there are a number of eligibility criteria that you need to meet. However, the government has introduced the new ECO+ scheme in spring 2023. This new scheme is available to help a wider range of UK homes that have lower efficiency ratings.

 Whether or not you’re eligible for these grants, you’ll still want to make sure you’re getting the best possible deal on double glazing and avoid overspending. In order to do this, you’ll need to compare prices from the best double glazing companies so that you can objectively choose the best deal.

Researching and comparing double glazing companies can be tedious and take up hours of your time. But don’t worry – we can help make this easier for you. Within 48 hours, we can connect you with up to 4 qualified installers from our network, so that you can easily compare their prices side by side and choose the best one.

Average cost of double glazing a 4 bed house

A 4 bed house in the UK is usually either detached or semi-detached and has between 12 to 15 windows. In the table below, you can find the average cost of double glazing a 4 bed house in the UK for different materials based on this number of windows:

Average cost of double glazing a 4 bed house in the UK*
uPVCWoodAluminium
£6,600 – £11,100£7,680 – £15,375£7,320– £13,350
*These numbers are based on homes with 12-15 windows (900 x 1200mm)

As you can see, the cheapest frame material for double glazing a 4 bed house is uPVC. However, with this being said, it’s important to keep in mind that the prices above are only averages. Therefore, it’s still possible to find good deals on the other types of frame materials, such as softwood windows. The price will also vary depending on the quality and your installer’s rates.

As well as the frame material, the style of window can also affect the cost. The table below showcases the average cost of double glazing windows for a 4 bed house based on these two factors:

Average cost of double glazing window types for a 4 bed house*
Window typeuPVCWoodAluminium
Casement£6,600 – £8,250£7,680 – £9,600£7,320 – £9,150
Tilt & turn£8,160 – £10,200£10,200 – £12,750£8,880 – £11,100
Sash£8,880 – £11,100£12,300 – £15,375£10,680 – £13,350
Bay£17,520 – £21,900£23,760 – £29,700£22,800 – £28,500
*These numbers are based on homes with 12-15 windows (900 x 1200mm)

Casement and sash windows are two of the most popular window types in the UK, meaning that you will likely find options that lie well outside of the price ranges mentioned in the table above for these two in particular.

The estimated price for double glazing a 4 bed house will also vary depending on whether you want different types of windows for different rooms or not. For example, some Victorian homes in the UK will have just one bay window in the living room and then single sash windows in the rest of the house. You can calculate an estimate from the table with the average price for one window mentioned in the previous section.

Getting the best price on double glazing

There are an abundance of double glazing installers across the UK, from small local companies to nationwide firms. Many of the best double glazing companies will offer quality windows with lengthy guarantees and high energy efficiency ratings, so you know that you’re getting your money’s worth.

You might assume that hiring an installer from one of the well-known nationwide firms is the best option. However, this isn’t necessarily the case. Local installers come with many benefits, such as a more personalised service and they won’t need to raise their rates in order to cover travel expenses. This is why it’s important to consider all of your options and compare prices.

Local installers also will usually be able to finish the project faster, since large suppliers give priority to larger residential and commercial projects. 

But how much is double glazing for a 4 bed house and how do you figure out what each installer is offering?

Trying to figure this out on your own can take up hours of your time and a lot of effort, as you’ll need to research and call up various installers one by one. But thankfully, there’s a solution. At Greenmatch, we can put you in touch with our network of qualified installers in order to help you find the best deal from a double glazing installer in your area.
