So, How Much Does It Cost to Get New Windows Fitted?
If you’re planning a home improvement project, one of the most important questions you’ll ask is: how much does it cost to get new windows fitted? The answer depends on several factors, including window type, material, glazing, and the complexity of the installation. Understanding these variables will help you budget accurately and avoid unexpected costs.
In this guide, we’ll break down average UK prices, explain what affects those prices, and show how to make informed decisions that offer long-term value.
Average Cost of New Windows (Supply and Installation)
On average, the cost to get new windows fitted in the UK ranges from £500 to £1,200 per window, depending on the style and material. Here’s a rough breakdown of typical prices:
| Window Type | Average Cost (Per Window) |
|---|---|
| Casement Window | £500 – £900 |
| Sash Window | £800 – £1,500 |
| Flush Fit Window | £700 – £1,200 |
| Bay Window | £1,200 – £2,500 |
These figures include both the supply of the window and professional installation. Costs may vary based on your location, the condition of the property, and the number of windows being replaced.
What Affects the Cost of New Windows?
1. Window Style
Some styles require more material, craftsmanship, or installation time. For example:
- Sash windows are typically more expensive due to their traditional design and sliding mechanism.
- Bay windows are made of multiple panes and may need additional structural support.
- Flush windows offer a modern appearance but usually cost more than standard casement options.
2. Frame Material
The material of the window frame plays a major role in the price:
- uPVC – Affordable, durable, and low maintenance.
- Aluminium – Sleek, strong, and long-lasting, but more expensive.
- Timber-look uPVC – Gives the appearance of wood without the upkeep, priced between uPVC and aluminium.
A company like Skyway Windows offers all of these options, helping you choose the right material for your needs and budget.
3. Glazing Type
Double glazing is standard, but triple glazing and other upgrades can increase the cost.
- Double glazing: Balances performance and price.
- Triple glazing: Offers improved thermal and acoustic insulation.

4. Energy Efficiency
Higher-performing windows cost more upfront but save money over time. A-rated windows help:
- Lower energy bills
- Improve indoor comfort
- Increase property value
Make sure your chosen installer explains the window’s U-value and its efficiency rating.
5. Installation Complexity
Not all installations are straightforward. Costs may rise if:
- Windows are located on upper floors
- Existing frames need repair or removal
- Brickwork or internal plastering requires attention
Choosing a professional installer ensures the job is completed safely and in compliance with regulations.
Do You Need a FENSA Certificate?
Yes. For most window replacements, a FENSA certificate is legally required to prove the work meets UK Building Regulations. This certificate is essential when selling your home and avoids the need for local authority inspections.
To ensure compliance, always choose a FENSA-registered installer. You can verify registration for Skyway Windows using the FENSA installer checker. For further legal requirements, visit the LABC.
Should You Replace All Your Windows at Once?
Replacing all your windows at the same time may seem costly, but it can offer long-term benefits:
- Better energy efficiency across the whole home
- Lower installation costs per window
- Consistent appearance and finish
It’s worth getting a quote for full-house replacements to see how much you could save.
Additional Products to Consider
Alongside windows, many homeowners also invest in upgrading doors for improved security and visual consistency. Options include:
- Composite entrance doors – Strong, insulated, and low maintenance.
- Aluminium bifold doors – Great for open-plan living and garden views.
- Aluminium patio sliding doors – A sleek option for maximising light and access.
Bundling windows and doors can help reduce overall installation costs and simplify project coordination.
