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.
