How much does underpinning cost? London indicative rates: traditional mass concrete £1,500–£3,000 per linear metre; beam-and-base £2,000–£3,500/m; mini-piled £2,500–£4,500+/m. A typical single-elevation scheme of 6–8 metres therefore runs roughly £10,000–£24,000 before design fees, party wall costs and reinstatement. Method is an engineering decision from ground investigation — and remember most investigated subsidence never needs underpinning at all.

Important: this tool provides general, indicative guidance only. It is not a survey, a diagnosis or a quotation, and it cannot assess your specific property. Figures are broad London planning ranges; the appointed professional confirms actual fees and any repair costs are confirmed by contractors pricing an engineered specification. If you are concerned about your property, request a structural assessment or call.
