How Much Do New Windows Cost? A Homeowner’s Guide

Replacing your windows is a significant investment, so it’s natural to want a clear idea of costs before you start. While every home and project is different, this guide walks through the main factors that affect pricing so you can budget with confidence.

The figures below are general guide ranges only, intended to give a rough sense of scale — actual costs vary by property, product choice and specification. For an accurate figure, the best step is always a free, no-obligation quote.

What Affects the Cost of New Windows?

• Material: uPVC is typically the most cost-effective, with aluminium and timber costing more.
• Number and size of windows: Larger openings and full-house replacements naturally cost more than a single window.
• Style: Simple casement windows are generally cheaper than more complex styles like bay windows, sash windows or bi-fold doors.
• Glazing type: Double glazing is standard, but triple glazing or acoustic glass will increase the price.
• Installation complexity: Access, the condition of existing frames, and any structural work required can all affect labour costs.

General Price Ranges

As a very rough guide, a single standard uPVC casement window supplied and fitted often falls into the low-to-mid hundreds of pounds, with aluminium or larger/more complex styles costing more. A full house of new windows is a bigger investment, often running into the thousands depending on the size of the property and number of openings.
