When it comes to upgrading your home, windows play a crucial role. They affect your home's appearance, energy efficiency, and security. But before you dive into a window replacement project, it’s important to understand the cost of installing windows. This knowledge helps you plan your budget wisely and choose the best options for your home.
What Influences the Cost of Installing Windows?
Several factors affect how much you’ll pay for new windows. Knowing these can help you make informed decisions and avoid surprises.
Type of Window
The style and type of window you choose have a big impact on price. For example:
Single-hung and double-hung windows are common and usually more affordable.
Casement windows offer better ventilation but can cost more.
Bay and bow windows are larger and more complex, so they tend to be pricier.
Material Matters
Window frames come in different materials, each with its own price range:
Vinyl is popular for being cost-effective and low maintenance.
Wood offers a classic look but requires more upkeep and costs more.
Aluminum is durable but less energy-efficient.
Fiberglass is strong and energy-efficient but can be expensive.
Size and Number of Windows
Larger windows or custom sizes will increase the cost. Also, the more windows you replace, the higher the total expense, though sometimes you can get a discount for multiple installations.
Installation Complexity
If your home has unusual window openings or requires structural changes, expect higher labour costs. Removing old windows carefully and preparing the space can add to the time and effort needed.
Energy Efficiency Features
Energy-efficient windows often come with a higher upfront price but save money in the long run. Features like double or triple glazing, low-E coatings, and gas fills between panes improve insulation.

Breaking Down the Cost of Installing Windows
Let’s look at the typical costs involved in window installation to give you a clearer picture.
Window Price Range
Basic vinyl windows: £150 - £400 each
Wood-framed windows: £300 - £700 each
Fiberglass windows: £400 - £900 each
Bay or bow windows: £1,000 - £3,000+
Labour Costs
Professional installation usually costs between £100 and £300 per window, depending on complexity and location. Labour includes removing old windows, fitting new ones, sealing, and finishing.
Additional Expenses
Disposal of old windows: Some companies charge for this service.
Structural repairs: If your window openings need fixing, this adds to the cost.
Permits: Check if local regulations require permits for window replacement.
Example Budget

Windows: 10 x £250 = £2,500
Labour: 10 x £150 = £1,500

Total: Around £4,300
How to Choose the Right Windows for Your Home
Choosing windows is not just about price. Here are some tips to help you pick the best fit.
Prioritise Energy Efficiency
Look for windows with a good energy rating. This helps reduce heating bills and keeps your home comfortable year-round. Double or triple glazing and low-E coatings are great features to consider.
Match Your Home’s Style
Windows should complement your home’s architecture. For example, sash windows suit period homes, while casement windows fit modern designs.
Consider Maintenance
Vinyl and fiberglass windows require less upkeep than wood. If you want low maintenance, these materials are better choices.
Think About Security
Choose windows with strong locks and toughened glass to improve your home’s security.
Get Multiple Quotes
Always get at least three quotes from reputable installers. This helps you compare prices and services.

Replace multiple windows at once: Installers often offer discounts for larger jobs.

Look for government grants or incentives: Some schemes support energy-efficient home improvements.
