Cost of double glazing a 4 bed house in the UK
Double glazing a 4-bedroom UK house typically costs £2,400 to £38,850, but the cost can vary widely depending on several factors.
- Type: Casement windows are the most affordable, while sash or bay windows cost more.
- Size: Larger windows require more materials and labour, increasing prices.
- Frame material: uPVC is the most budget-friendly, followed by wood and aluminium.
- Energy efficiency rating: Higher-efficiency windows cost more upfront but save money on energy bills.
- Number of windows: A 4-bedroom house typically has 12-15 windows; however, this can vary.
For an indication of how these factors affect window prices, you can take a look at the estimated cost of 1 double glazed window based on its style and frame material:
| Window type | uPVC | Aluminium | Wood |
|---|---|---|---|
| Casement | £200 – £250 | £260 - £925 | £300 - £1,065 |
| Tilt & turn | £250 - £890 | £325 - £1,155 | £375 - £1,330 |
| Sash | £300 - £1,065 | £390 - £1,390 | £450 - £1,600 |
| Bay | £1,190 – £1,725 | £1,550 - £2,250 | £1,785 - £2,590 |
As you can see, uPVC tends to be the cheapest window frame material on the market, regardless of the window style you opt for. Wooden double glazed windows, on the other hand, are the most expensive choice, even though they are also the most durable. Aluminium window prices are somewhere in between uPVC and wood, and can offer a modern finish to your home while allowing for thinner frames that optimise light entry.
Now that you have an idea of how much a single double glazed window costs, you’re probably wondering: “How much do new windows cost for a 4 bedroom house?” Here’s a rundown:
| Window type | uPVC | Aluminium | Wood |
|---|---|---|---|
| Casement | £2,400 - £3,750 | £3,120 - £13,875 | £3,600 - £15,975 |
| Tilt & turn | £3,000 - £13,350 | £3,900 - £17,325 | £4,500 - £19,950 |
| Sash | £3,600 - £15,975 | £4,680 - £20,850 | £5,400 - £24,000 |
| Bay | £14,280 - £25,875 | £23,250 - £33,750 | £21,420 - £38,850 |
Hopefully these estimates have given you an idea of the cost of double glazing a 4 bed house in the UK. As you can see, the costs are quite high and they may be difficult to bear on your own. Fortunately, there are multiple government grants available, which can fund energy-efficient upgrades, such as double glazing.
Grants for double glazing a 4 bedroom house
Currently, there aren’t any UK government grants geared specifically towards windows. However, there are several incentives that address energy efficient upgrades, which include double glazed window installation. These are:
- Energy Company Obligation (ECO4): Available in England, Scotland, Wales, this scheme provides funding for energy efficiency upgrades to households in fuel poverty. Exactly how much you can receive and what kind of window installation you can get through this scheme depends on your specific situation, so be sure to check your eligibility.
- Affordable Warmth Scheme: This scheme is open to applicants based in Northern Ireland who are looking to install double glazing. To be eligible for funding, you must meet specific annual income requirements, such as having an income of less than £23,000 per year.
- Home Upgrade Grant (HUG2): This grant is available in the entire UK and offers funding for new windows, doors, and draught-proofing measures. Applicants must meet specific criteria to be eligible, such as have a low income, live off-grid, or live in a home with a low energy efficiency rating.
- Home Energy Scotland Grant and Loan: Open to Scottish homeowners, this grant and loan provides funding for upgrades from single to double glazing. If you’re looking to apply, it’s good to know that as of August 2024, funding will only be provided for existing buildings and not for those who are building new homes.
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 to avoid overspending. To do this, you'll need to compare prices from the best double glazing companies so that you can choose the best deal.

Average cost of double glazing for a 4 bedroom 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 depending on different frame materials:
| uPVC | Aluminium | Wood |
|---|---|---|
| £8,340 – £14,810 | £13,185 – £23,810 | £12,510 – £27,410 |
Considering that the costs above are for 12 - 15 windows, you can use the average figures we’ve listed above for other calculations. For instance, you can create lower estimates based on the number of windows in your home if you’re trying to calculate the cost of double glazing a 2 bed house (UK) or the average cost of new windows for a 3 bed house in the UK.
It’s good to note that the average price of 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. So, be sure to consider this in your calculations. Replacing a like-for-like window is also cheaper than switching from one design to another as this can require extensive installation.
Should you replace your windows in your 4 bed house?

That said, the cost of new windows for a 4 bed house is quite high.
