The average double-glazed windows cost in Scotland is £400 to £800 per window. For a full house, most people pay between £3,000 and £7,500, depending on the number of windows and the type you choose.
Basically, smaller homes are less expensive and larger homes are more expensive due to the number of windows and the materials used. The final price you see is likely to include both the cost of the materials and the installation, so you usually do not have to worry about getting separate estimates.
How Much Does Double Glazing Cost Per Window?
The cost of the window itself is usually determined by the cost of the frame and the glass. There are options across the board for every price point.
Here is a simple breakdown:
| Window Type | Average Cost (Per Window) |
| uPVC | £400 – £800 |
| Aluminium | £600 – £850 |
| Timber | £750 – £1,100 |
| Triple Glazing (uPVC) | £550 – £900 |
Because of the low maintenance and lower price, uPVC is the most popular. Aluminium is more expensive but is more modern-looking. And Timber is the most expensive but is classically beautiful.
Triple glazing costs more than double glazing, but it is not always needed for every home.
How Much Does It Cost to Install Double-Glazed Windows in a House?
Typically, the cost of windows for a whole house is determined by the number of windows in the house.
Here are some real-life examples to help you understand better:
| Property Type | Number of Windows | Average Cost |
| Small house / flat | 4–6 windows | £2,000 – £3,500 |
| 2-bedroom house | 6–8 windows | £3,000 – £5,000 |
| 3-bedroom house | 8–12 windows | £4,000 – £7,500 |
| Large house | 12–15+ windows | £6,000 – £10,000 |
For example, if you place 10 windows on a standard uPVC double-glazed window, you can expect a cost of around the range of £4,000 to £5,000.
The cost of replacement windows increases with the number of windows, although the cost per window decreases with larger contracts.
What Affects the Double Glazed Windows Cost?
The total double-glazed windows cost varies based on a number of important factors.
- First, window size matters. Larger windows need more glass and materials, so they cost more.
- The second is the window style. Simple designs like casement windows are cheaper; more complex windows, like bay and sash windows, are more expensive.
- Then you have your frame materials. The least expensive frame material is uPVC; the more expensive frame materials are timber and aluminum.
- Then comes labour cost because installation charges depend on how easy or difficult the job is.
- Your location can also affect the price. In some areas, labour and materials cost more.
- Finally, the type of glazing matters. Standard double glazing is affordable, while triple glazing or special glass increases the cost.
How Much Do Double Glazed Windows Cost by Type?
Different window styles come with different price ranges. Some are simple and budget-friendly, while others are more expensive.
Here is a quick overview:
| Window Type | Average Cost |
| Casement | £400 – £800 |
| Sash | £700 – £1,200 |
| Tilt & Turn | £500 – £900 |
| Bay | £1,200 – £3,000 |
Casement windows are the cheapest and most common. Sash windows are more expensive because of their design. Tilt and turn windows offer more flexibility, so they cost a bit more. Bay windows are the most expensive because they include multiple panels.
How Much Do Different Window Materials Cost?
The material you choose will change both the price and the look of your windows.
Here is a simple comparison:
| Material | Cost Range | Best For |
| uPVC | £400 – £800 | Budget-friendly homes |
| Aluminium | £600 – £850 | Modern designs |
| Timber | £750 – £1,100 | Traditional homes |
uPVC is the best choice if you want to save money. Aluminium is strong and stylish but costs more. Timber looks beautiful, but it needs maintenance and has a higher price.
How Much Does Labour Cost for Double Glazing Installation?
For a single window, labour usually costs around £75 to £150, depending on the job. If you hire installers by the day, a team of two workers may charge around £400 to £600 per day.
For a full house, labor costs typically range from £500 to £1,800, based on the number of windows and the level of difficulty. Average installations usually range between 1 and 3 days.
What Additional Costs Should You Expect?
Aside from the primary cost, there are some other expenses to consider.

There may also be waste removal costs, especially if old windows are not included in the quote. This can cost around £125 to £320.
If you choose upgrades like better glass or special finishes, your total cost will increase.

Double vs Triple Glazing – Which Is Better for Your Budget?
Double glazing is the most common choice because it offers a good balance between cost and performance.
Triple glazing is more expensive, at about £1,200 or more, but it insulates better.
Triple glazing might be more useful if you live in a particularly cold or loud region. For most regions in Scotland, including the majority of homes, double glazing should be more than sufficient.
So, if you are on a budget, double glazing is the better option.
How Can You Reduce Double Glazing Costs?
If you want to save money, there are a few simple ways to reduce your total cost.
