How much do new windows cost in the UK?

The cost of replacing windows depends on the material, glazing type, size and number of units required. Labour and regional differences also play a role.

As a general guide:

• uPVC windows: £500-£900 per window
• Aluminium windows: £750-£1,500 per window
• Timber windows: £1,000-£2,000 per window
• Full house replacement (8-12 windows): £5,000–£15,000+

Triple glazing and specialist designs (such as bay or sash windows) will increase costs further.

While price is important, it’s equally vital to consider installation quality and product performance. Poor installation can compromise insulation and longevity, regardless of window type.

Why replace your windows?

Homeowners typically upgrade their windows for a combination of reasons. Replacing your windows can:

1. Reduce heat loss

Up to 20 per cent of a home’s heat can escape through inefficient windows. Modern double or triple glazing improves thermal performance and can help maintain consistent indoor temperatures.

2. Lower energy bills

Energy-efficient windows reduce reliance on heating systems, particularly during colder months. While savings vary by property, upgrading from single glazing can make a noticeable difference.

3. Improve comfort

Draughts, condensation and external noise are common issues with ageing windows. New installations often improve insulation and soundproofing.

4. Enhance security

Modern window systems typically include multi-point locking mechanisms and tougher glazing, offering improved security.

5. Update appearance

New windows can significantly improve kerb appeal – particularly when replacing dated frames or mismatched styles.

Choosing the right window type

Different materials offer different benefits:

uPVC

Low maintenance and cost-effective, uPVC remains the most common option in the UK.

Aluminium

With slimmer frames and a contemporary look, aluminium is durable but typically more expensive.

Timber

Often chosen for period properties, timber offers a traditional aesthetic but requires more maintenance.

Your choice will depend on budget, property type and long-term performance goals.

Are energy-efficient windows worth it?

Windows are rated for energy performance using the Window Energy Rating (WER) system. A-rated windows offer strong thermal efficiency and can contribute positively to a property’s EPC rating.

While upfront costs may be higher, improved insulation and comfort can justify the investment over time – particularly in older homes with single glazing.

What affects installation costs?

Several factors influence the final quote:

• Number of windows
• Property access
• Frame material
• Glazing type
• Structural adjustments required
• Location within the UK

Obtaining multiple quotes allows you to compare prices, and also look at warranty length, guarantees and aftercare support.

How to compare window quotes effectively

When reviewing quotes, consider:

• Is installation included in the total price?
• What guarantees are provided?
• Are installers FENSA or CERTASS registered?
• Is the glazing specification clearly outlined?

Avoid making a decision based solely on the lowest price. Transparency and accreditation matter.
