Double Glazing across the UK

Double Glazing - what to expect

Doing the whole house at once - rather than window by window over several years - gets you a single matched finish, one set of scaffolding and access costs, and usually a better per-unit price. It's the biggest glazing decision most homeowners make, and quotes for the same house can vary by thousands.

A typical 3-bed semi runs 8-12 openings including doors, and full replacement lands somewhere between £3,000 and £9,000 depending on frame material, glazing spec, colour and how many are bay or feature windows. uPVC sits at the lower end, timber-alternative and aluminium at the top. The single biggest swing is whether any bays need structural work above them.

Whole-home jobs are where finance offers and 'today only' discounts get pushed hardest. A genuine quote holds its price for at least a week and itemises each opening so you can see what you're paying for. Walk away from anything that only works if you sign on the visit.

Typical UK price range for double glazing: £3,000 - £9,000 installed. Actual figures for your city sit on the city page below.
