UPVC double glazed windows are still the default choice for the majority of UK homeowners - they hit the sweet spot between price, thermal performance and low maintenance. A properly specified A+ rated UPVC casement now delivers a whole-window U-value below 1.2 W/m²K, well inside the current Building Regulations Part L threshold, and modern flush-sash and heritage profiles finally look at home on Victorian and Edwardian stock rather than fighting it.

Prices are driven by three things: the frame (60mm chambered UPVC vs. 70mm+ triple-chamber, standard white vs. RAL foil or woodgrain, single vs. double gasket), the glazing unit (28mm double A-rated as a baseline, 44mm triple for £120-£180 extra per m², warm-edge spacers, argon or krypton fill), and how the window opens - fixed panes are cheaper, tilt-and-turn or fully reversible sashes carry a hardware premium. A mid-range A-rated casement in white typically lands at £450-£650 fitted per opening; upgrade to A+, anthracite grey foil and Yale multi-point locks and you're closer to £700-£900.
