So, How Much Should It Cost to Install Windows?
If you’re planning a window upgrade, one of the first questions you’ll likely ask is: how much should it cost to install windows? The answer depends on several factors, including the window style, material, glazing type, and the number of windows being replaced.
We’ll break down the typical costs involved, highlight what influences those costs, and explain how to make sure you’re getting good value without compromising on quality.
Average Cost to Install Windows in the UK
The cost to install new windows in the UK generally falls within these ranges:
| Window Type | Average Cost Per Window (Supply & Fit) |
|---|---|
| Casement Window | £500 – £900 |
| Sash Window | £800 – £1,500 |
| Flush Fit Window | £700 – £1,200 |
| Bay Window | £1,200 – £2,500 |
These prices include the supply of the window itself and professional installation by a qualified fitter. However, factors such as location, glazing options, and installation complexity can all affect the final price.
What Affects Window Installation Costs?
1. Window Style
Certain styles require more material and labour. For instance:
- Sash windows often cost more due to their detailed construction and traditional appearance.
- Flush windows tend to be more expensive than standard casement styles due to their seamless design.
- Bay windows involve multiple panels and additional structural support, which increases costs.
2. Frame Material
Your choice of frame material will influence both the upfront cost and the long-term value.
- uPVC – The most budget-friendly option. It offers excellent insulation and minimal maintenance.
- Aluminium – More expensive but offers slim sightlines and outstanding durability.
- Timber-look uPVC – Offers the appearance of wood without the upkeep, typically priced between uPVC and aluminium.
To maintain a modern aesthetic and superior strength, many homeowners choose external aluminium doors or frames that match their window finish.
3. Glazing Options
Windows come with either double or triple glazing. Triple glazing is more expensive but offers superior insulation and soundproofing, which may be important if you live near busy roads or flight paths.
- Double glazing – Standard option offering solid energy efficiency.
- Triple glazing – Higher cost, better for thermal and acoustic performance.
4. Energy Efficiency
Opting for A-rated energy-efficient windows may cost more initially but can save you money on heating bills. These windows are designed to retain heat and prevent draughts.
For more on window performance standards, visit the British Fenestration Rating Council (BFRC), which certifies windows based on thermal efficiency.
5. Labour and Installation Complexity
Installation costs vary based on:
- The number of windows being installed.
- Accessibility (e.g. second-floor windows).
- Whether old frames or lintels need replacing.
- The condition of surrounding brickwork or plaster.
While it may be tempting to look for the cheapest quote, poor-quality fitting can lead to draughts, leaks, and long-term issues. Always choose a FENSA-registered installer to ensure compliance with UK Building Regulations. You can verify Skyway Windows on the FENSA website.
Further advice on compliance and installation standards can be found on the LABC website.
Cost-Saving Tips Without Compromising Quality
If you’re working within a budget but want long-lasting results, consider these tips:
1. Replace Multiple Windows at Once
Most installers offer lower prices per window if you’re replacing several at once. This also reduces labour costs overall.
2. Choose Styles That Match Existing Openings
Avoid major structural changes unless necessary. Sticking with the existing window size and style can reduce installation costs.
3. Balance Performance and Budget
If triple glazing or aluminium frames push you over budget, opt for high-quality double-glazed uPVC windows instead. They still provide excellent insulation at a lower cost.
Explore casement windows as a simple, effective, and affordable option that suits most homes.
4. Consider Energy Savings as Long-Term Value
Although A-rated windows may cost more upfront, they can significantly lower your energy bills over time—especially during winter.
FAQs About Window Installation Costs
Q: Does the cost include removal of old windows?
Yes, most professional quotes include removal and disposal of existing windows, but it’s always best to check.
Q: Will I need to pay extra for a FENSA certificate?
No, FENSA registration is usually included as part of the service. This certificate proves your windows comply with UK Building Regulations and can be crucial when selling your home.
Q: Are window grants or finance options available?
Some installers offer finance plans, and you may be eligible for home improvement loans or energy efficiency grants. It’s worth checking with your local authority or installer.
