What influences the cost of double glazing a 2-bed house
- Number of windows: The number of windows is the primary factor that can increase costs.
- Window size: Larger windows tend to cost more than smaller windows and can be more complex to install. Costs can also increase if the surrounding wall needs to be altered.
- Frame material: The material used for the frame can increase the cost, with wooden windows being more expensive than uPVC and aluminium windows.
- Window design: Different types of windows can have more complex components, which increases the price per unit. Swapping one type of window frame for another can also increase costs as well since many features will need to be swapped out.
- Type of glazing: Double glazed windows are the standard, but many homeowners living in colder regions can opt for triple glazing. For reference, the cost of triple glazed windows will be about 30% to 50% higher.
- Installer rates: What the installer charges can vary depending on location, personal rates, the extent of the work, and whether they are swapping one type of window for another (which increases labour costs).
While we provide numerous prices, these factors can make it difficult to give an exact estimate. For a precise price, you’ll need an installer. However, a reliable one is the only way to get the best prices. This can take hours of research, and even then, it may not provide you with the best options. That’s why our service is far better.

Double glazing 2-bed house installation cost
Installation costs can be £350 to £600 to fit two windows. Installing more windows can get a bit cheaper as bulk discounts apply, but this depends on your choice of installer. More complex installations will require more man-hours and thus increase labour costs.
| Number of windows | Installation cost |
|---|---|
| 2 | £350 to £600 |
| 4 | £500 to £1,200 |
| 6 | £1,000 to £2,400 |
| 8 | £2,000 to £3,000 |
The end cost of installation will vary based on the complexity of the installation, the rates of the installer, and the purchase costs of the window. Installations can be more complex if you are swapping one window out for a different one or if you need to create space for a window by taking out sections of the existing infrastructure.
Double glazing grants like the ECO4 scheme can also help cut down the costs of both purchase and installation. It's also worth noting that these grants do not cover triple or secondary glazing.
Should you get double glazing for your 2-bed house?
Double glazing doesn’t just cut down on energy costs, it also makes windows more secure and maintains adequate temperatures in the home. It can improve your home’s energy performance certificate, allowing for a better valuation of the home. Compared to other forms of improving home heating, it can also be relatively cheap, depending on the number of windows, since the average cost of new windows for a 2 bed house in the UK will be £2,500 to £4,000.
Another advantage is that new windows can reduce noise transmission into the home while keeping out noise as well. They allow for additional comfort and help homes conform to modern heating standards without increasing gas or electricity costs.
However, the efficiency and quality of your windows will depend on proper installation, which requires finding a reliable installer. This can take hours of looking up companies and comparing their offers, which still may not yield the best results. To make absolutely sure you’re getting the installation you deserve quickly, our service is the perfect solution.
