Casement windows are the UK's default style - hinged on the side, opening outward. In uPVC they're the cheapest window to replace and the fastest to fit. If your existing frames are pre-2005 or single-glazed, A-rated casements typically pay back in energy savings within 8-12 years.
The single biggest price driver is glass area, not the exact frame - a 1200x1200mm casement costs roughly the same in white uPVC or a basic foiled finish, but jumps for triple glazing or a flush-sash profile. Standard installs use argon-filled double glazing with a warm-edge spacer; upgrading to triple glazing adds around 15% for a marginal thermal gain in most UK climates.
