uPVC windows are the default replacement choice in the UK - roughly three quarters of homes fit them - because they're the cheapest route to an A-rated, low-maintenance frame. If your current windows are pre-2005 or anything is single-glazed, new uPVC units usually pay back in energy savings within 8-12 years.
Frame material matters less than people expect - the glass area and the sealed unit spec drive most of the price. A standard install uses a 28mm argon-filled double-glazed unit with a warm-edge spacer and a low-E soft coat; triple glazing adds around 15% for a thermal gain that only really pays off in exposed or northern locations. Foiled finishes (Anthracite Grey, black, woodgrain) add roughly 10-20% over white.
