Builder quote FAQs

How much per m² for a rear extension in the UK?

£1,800–£2,600 per m² is a fair mid-market range in 2025/26, excluding kitchen supply and VAT. London and premium finishes push higher.

How much deposit should a builder ask for?

Never take more than is needed to cover materials for the next phase — typically 10–20% up front, then staged payments against milestones you both sign off.
