How to choose
Start with the material. uPVC is the cheapest and needs no upkeep; aluminium gives slimmer frames and more glass; timber looks right on a period house and is often the only choice in a conservation area. Then pick the style that matches the house: casements for most homes built since the war, sliding sashes for Georgian, Victorian and Edwardian houses, and a bay where one is already there.
