What drives the price
- Material: uPVC is the budget anchor; timber and aluminium carry the premium.
- Size and opening style: bays, sashes and doors price differently from casements.
- Glazing spec: double is standard; triple and acoustic glass add per unit.
- Installation access: upper floors and conservation details add labour.
All figures come from the same validated 2026 price data as the calculator above (sources: Checkatrade, MyJobQuote and comparable national 2026 cost guides, checked August 2026; see how we price), so this page and your estimate can never disagree.

Frequently asked questions
How many windows should I replace at once?
Whole-house replacement gets a better per-window price than one-by-one, and one installation visit. But mixing is fine: many owners do the weather-beaten side now and the rest later. The calculator prices any number of units.
Do these prices include VAT?
Yes, all ranges include 20% VAT. New builds and some energy-saving works can qualify for 0% or reduced VAT; ask your installer whether your project applies.
How much does the region matter?
A lot: London typically runs 20 to 35 percent above the national average (this site plans with +25%, the quarter mentioned above), and the North of England, Scotland and Northern Ireland sit 10 to 20 percent below. The calculator adjusts for your region automatically, and the regional overview shows every factor.
How accurate is this range?
It is a guide range from national 2026 cost guides, adjusted for finish level and region. Real quotes vary per trade, property and specification; treat it as a starting point, budget 10 to 15 percent contingency, and always get at least three itemised quotes.
