In the table below, you can see the average costs of double glazing 1 window based on the material of the window frame:

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. If you're thinking of opting for wooden double glazed windows, 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.

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.

For instance, installing 8 uPVC casement windows in a semi-detached house would cost around £3,940, while ten wooden sash windows would cost roughly £11,100. As a result, the average cost per window can vary depending on your choices.

For example, a single uPVC window typically ranges from £200 to £1,065, while a wooden window can cost between £300 and £1,600, and aluminium windows fall between £260 and £1,390.

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 £1,190 to £2,700,, depending on the type of frame you desire.

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.

It typically costs between £4,000 – £16, 500 to replace the windows in a 3 bed house in the UK with double glazing, including installation. Opting for uPVC windows can lower costs, which you might consider if you need to replace your double glazed windows on a budget. 

Please keep in mind that these prices are just an average. You may find prices outside of this depending on the quality of the window, potential discounts, and your installer’s rates. This will also be affected by the window style and material, as shown below:

Casement and sash windows are the most widely available options, so  it’s likely that you will  find varying prices for these two types in particular. If you wish to have different window styles for different rooms in your home this will also affect the overall price.

With so many local double glazing installers out there, it can be difficult to know which one to choose. Many of us automatically opt for one of the larger nationwide companies, however, if you don’t consider local installers, you could miss out on some great deals.
