Before you ask for quotes
Three things set the price of new windows: how many you have and how big they are, the style and frame you choose, and who fits them. Count your windows, note any bays or very large panes, and the page for your type of home shows where the money goes and what a quote should include.
In England and Wales, replacement windows have to meet the building regulations for energy efficiency. A fitter registered with FENSA or CERTASS can certify the work, and you will want that certificate when you sell. Scotland and Northern Ireland have their own rules, which the local pages cover.
