Cost of Double Glazing a 3 Bed House (UK): Explained

Therefore, double glazing is one of the best ways to insulate your 3 bed home and save on your heating bills. Even though double glazing is financially beneficial in the long run, you still need to consider the upfront costs.
The cost of double glazing a 3 bed house in the UK depends on a variety of factors. Firstly, factors relating to the window itself, such as the window size and window type. And secondly, factors relating to the installation, such as whether you opt for a local or nationwide installer, and whether you only need replacement double glazed units or a whole window replaced.

Cost of double glazing a 3 bed house
There are many factors to take into consideration when it comes to the cost of double glazing a 3 bed house. This includes the type of window you’re looking for, its size, and frame material. As well as, of course, the number of windows you need double glazed for your home.
In the table below, you can see the average cost of double glazing 1 window based on the material of the window frame:
| Average cost of double glazing 1 window* | ||
|---|---|---|
| uPVC | Wood | Aluminium |
| £635 | £800 | £775 |
As you can see, uPVC windows are on average the cheapest. This is also one of the main reasons why they’ve become a popular choice in the UK. If you’re thinking of opting for wooden double glazed windows then you’ll also need to think about whether you would like hardwood or softwood. Softwood is generally cheaper, as it typically takes less time to grow and process.
As well as the frame material, you also need to think about the style of window you’d like for your house. Sash windows are great for adding some character to your home, while tilt & turn windows offer flexible ventilation.
The table below shows the average cost for double glazing 1 window, based on window type and frame material. Steel is not included in the table as it is not as commonly used in UK homes compared to the other materials.
| Average cost of double glazing window type in 3 bed house* | |||
|---|---|---|---|
| Window type | uPVC | Wood | Aluminium |
| Casement | £550 | £640 | £610 |
| Tilt & turn | £680 | £850 | £740 |
| Sash | £740 | £1025 | £890 |
| Bay | £1,460 | £1,980 | £1,900 |
From the table, we can see that casement uPVC windows are the cheapest on average. Bay windows, no matter the material, tend to be the most expensive due to their size and unique shape.
If you’re looking for the cost of double glazing a 2 bed house (UK) or the cost of double glazing a 4 bed house (UK) then you can also use the average prices from the two tables above to calculate the cost of double glazing your home based on the number of windows you have.
Whatever type of home you live in, you’ll want to find the best double glazing windows for it. However, as you can already see, there are an abundance of options to choose from.

Average cost for double glazing 3 bed semi (UK)
A semi-detached house is when your home shares a wall with only one other house and likely has windows on all of its other sides. Semi-detached homes with 3 bedrooms are likely to have 8-10 windows in total. So what are the double glazing costs for a 3 bed semi house?
The average cost for double glazing a 3 bed semi in the UK, will not only depend on the number of windows you have, but also the type of window and frame material you would like.
For example, installing 8 uPVC casement windows in your semi-detached home would cost roughly £4,360. Whereas, installing 10 wooden sash windows would cost about £11,700.
Cost of double glazing a 3 bed terraced house
A terraced house is when your home is one of a row of similar houses which are connected by their side walls. Terraced houses typically have 2 or 3 bedrooms, with 3 bed homes typically having around 8 windows.
Like with other types of houses, the cost of double glazing a 3 bed terraced house will depend on multiple factors, such as the window type and frame material.
If you wish to install 8 double glazed uPVC sash windows in your terraced house then you can expect it to cost about £6,000.
Many Victorian terrace homes in the UK have a bay window in the living room, so if you’re looking to replace this then it could cost you about £1,500 to £2,430, depending on the type of frame you desire.
Window Grants in the UK
Searching for grants to help cover the costs of double glazing a 3 bed house is a great way to maximise your budget. At present, there are only a limited number of options available when it comes to covering costs for double glazing.
Primarily, there is the Energy Company Obligation (ECO). This scheme is now in its 4th iteration (ECO4) and is intended to run until the 31st March 2026. The goal of this scheme is to lower the UK’s energy consumption as well as support those who are living in fuel poverty.
Double glazing, whether it’s for double glazed doors or windows, is considered to be an energy efficient home improvement, therefore, it is covered by the ECO4 scheme. The efficiency of double glazing is also great news for both reducing your energy bills and carbon footprint.
There are a number of eligibility criteria you must meet in order to receive the ECO4 grant. However, the new ECO+ scheme was introduced in spring 2023, which is available to help a wider range of UK homes that have an efficiency rating of D or lower. The government predicts that it should help save households £310 a year on energy bills.
Regardless of whether you are eligible for these grants or not, it’s still important to get the possible deal on double glazing and save costs where you can. In order to get the best deal and ensure that you’re not being overcharged, you should always compare prices from the best local double glazing companies available to you so that you can objectively choose the best offer.

How to get the best price on double glazing
With so many local double glazing installers out there, it can be difficult to know which one to choose. The best double glazing companies in the UK should all offer you high energy efficient windows in a range of designs with lengthy guarantees.
However, these companies can’t state exact costs on their website since every window installation is unique and has different requirements. This makes it difficult to know where you can get the best price on double glazing.
Furthermore, when looking for a double glazing installer, many of us automatically think about opting for one of the larger nationwide companies. However, if you don’t consider local installers, you could be missing out on some great deals. Local installers tend to be more personal and don’t have to charge extra to cover long travel costs.
This is why it’s important to compare quotes from a variety of double glazing companies, so you can feel confident in knowing what your options are and avoid being overcharged.
