# Underpinning Costs

> The cost of underpinning: mass concrete £1,500–£2,600 per metre, resin injection £1,000–£1,800 per metre. Who pays after subsidence, plus free local quotes.

## Key facts

- Mass concrete underpinning typically costs £1,500–£2,600 per metre of wall in 2026 quotes; resin injection runs £1,000–£1,800 per metre (varies by region, depth and ground conditions).
- Most underpinning jobs are partial: a single corner of around 6 m at typical 2026 mass concrete rates works out at £9,000–£15,600, arithmetic on the per-metre range, not a quote.
- Where subsidence is covered by buildings insurance, the insurer typically funds necessary underpinning and the homeowner pays the policy excess, commonly around £1,000.
