Common questions
Direct, plain answers. No marketing copy.
How much does whole-house window replacement cost?
uPVC replacement on a three-bed house typically £6k to £10k; aluminium or timber runs £12k to £20k. Bifolds add £4k to £10k per opening. Use the Cost Planner for a postcode-adjusted range.
Do replacement windows need building-regs approval?
Yes, but FENSA or CERTASS registered installers self-certify, so there's no separate application. Compare Builders confirms registration during verification; you get the certificate your solicitor will ask for when you sell.
Why not get quotes from the big national brands?
You can, but expect a two-hour in-home pitch and a "today-only" discount. Verified installers on Compare Builders quote against the spec, and never get your number unless you appoint them.
