How much do new windows and doors cost in the UK? If you’re planning a project in 2026, it’s likely one of the first questions you’ll ask.

Several factors affect pricing, and understanding these early helps avoid surprises later:
Most windows and doors are made to order, which is why specification plays such a big role in pricing.
Typical guide price: from £900 to £2,500+ per window
Aluminium windows are known for their slim profiles, strength and contemporary appearance. Costs vary depending on frame depth, glazing performance and finish. Architectural or slimline systems typically sit at the higher end of the range.
Typical guide price: from £500 to £1,200 per window
uPVC windows remain a popular option for replacement projects thanks to their affordability, good thermal performance and low maintenance. Pricing is usually lower than aluminium or timber, particularly for standard sizes.
Typical guide price: from £1,200 to £3,000+ per window
Timber and timber-alternative windows are often chosen for period homes, conservation areas or where traditional detailing is required. Costs reflect the level of craftsmanship, detailing and finish involved.
Typical guide price: from £1,500 to £3,500+ per window
Sash windows are typically bespoke and therefore priced accordingly. Timber-alternative sash systems can offer the classic appearance homeowners want with modern performance and reduced maintenance.

Internal aluminium doors are increasingly used to divide spaces while maintaining light flow. Pricing depends on configuration, glazing style and finish.
It’s common for two homes with the same number of windows or doors to have very different budgets. For example:
