Frequently Asked Questions
For a typical 3-bedroom house in the UK with approximately 8 to 10 windows, you should budget between £5,000 and £12,000 for new windows including installation. uPVC casement windows with double glazing are the most affordable option at around £5,000 to £8,000 total. Timber sash windows or aluminium frames will push costs towards the higher end. Prices also vary by region, with London and the South East typically 10 to 20% more expensive than other parts of the country.
uPVC windows offer the best value for money in the UK for most homeowners, costing between £500 and £1,200 per window compared to £900 to £1,500 for timber. uPVC requires virtually no maintenance and can last 20 to 30 years. Timber windows, while more expensive upfront, add greater character and value to period properties and can last 60 years or more with proper maintenance. For listed buildings or conservation areas, timber may be the only permitted option, making the higher cost a necessary investment.
Repairing windows is usually cheaper in the short term, costing between £50 and £300 per window depending on the issue. However, if your windows are over 20 years old or have multiple problems such as draughts, condensation between panes, and difficulty opening, replacement is typically more cost-effective long-term. New energy-efficient windows can save £150 to £450 annually on heating bills, meaning the investment often pays for itself within 8 to 15 years through energy savings alone.
In most cases, you do not need planning permission to replace windows in the UK, provided the new windows are of a similar appearance and the building is not listed. However, if your property is in a conservation area, you may need approval, particularly if changing the style, material, or colour of the windows. All replacement windows must comply with Building Regulations for thermal performance and safety. Your installer should provide a FENSA or CERTASS certificate to confirm compliance.
Double glazing in the UK typically costs between £500 and £1,500 per window, depending on the frame material, window style, and size. A standard uPVC casement window with double glazing costs around £500 to £800. Sash windows with double glazing range from £900 to £1,500. Installation adds approximately £150 to £300 per window. These prices represent a significant investment, but double glazing can reduce heat loss by up to 50% compared to single glazing, delivering meaningful savings on energy bills.
The cheapest type of window to install in the UK is a standard uPVC casement window with double glazing, typically costing between £500 and £800 per window including installation. Fixed windows (non-opening) are even cheaper at around £300 to £500 each, but they do not provide ventilation. To keep costs down, choose standard sizes rather than bespoke dimensions, opt for white uPVC frames, and consider getting quotes from multiple FENSA-registered installers. Avoid the cheapest quotes, as they may indicate poor-quality materials or installation.
The lifespan of new windows in the UK depends on the frame material and quality. uPVC windows typically last 20 to 30 years before needing replacement. Timber windows can last 60 years or more with regular maintenance, including painting every 3 to 5 years. Aluminium windows are highly durable and can last 30 to 45 years. The double glazing sealed units within the frames usually last 15 to 25 years before the seals may fail and misting occurs. Choosing quality products and professional installation maximises longevity.
Several grants and schemes may help with the cost of new windows in the UK. The Energy Company Obligation (ECO4) scheme can provide funding for energy-efficient improvements, including windows, for households on certain benefits. Some local councils offer grants for home improvements. The Green Deal finance plan allows homeowners to pay for energy-efficient upgrades through savings on energy bills. Eligibility varies by scheme, so check the GOV.UK website or contact your local authority to find out what support is available in your area.
