Subsidence and structural repair
How much does underpinning cost?
Mass concrete underpinning typically costs £1,500–£2,600 per metre of wall; resin injection runs £1,000–£1,800 per metre and is far less disruptive. Most jobs need only part of the perimeter, not all of it, and where subsidence is behind it, your buildings insurer often pays, with an excess commonly around £1,000. Tell us about the property and local underpinning contractors will quote their exact price.
£1,500–£2,600
per metre, traditional mass concrete underpinning (typical 2026 quotes)
£1,000–£1,800
per metre, resin injection, less disruptive, days not weeks (typical 2026 quotes)

Typical underpinning costs, 2026
Last updated
What underpinning typically costs per metre of wall, by method, with illustrative job totals. These are typical quote ranges observed across the UK market in 2026, not fixed prices; depth, access and ground conditions move the number, and London sits at the top of each range.
Per-metre ranges reflect typical quotes for domestic underpinning observed across the UK market in 2026; they vary by region, depth, access and ground conditions. Job totals are arithmetic on those per-metre ranges at the stated wall lengths, illustrations, not quotes. Investigation, engineer's design, building control fees and internal reinstatement are additional. Get exact quotes for your property via the form above.
| Item | Typical cost (2026 quotes) | Notes |
|---|---|---|
| Mass concrete underpinning, per metre of wall | £1,500–£2,600 | Traditional dig-and-pour in sequenced pins; the benchmark method |
| Resin injection, per metre of wall | £1,000–£1,800 | Ground improvement by geopolymer injection; less disruptive, days not weeks, where ground conditions suit |
| Single corner or short wall, ~6 m, mass concrete | £9,000–£15,600 (illustrative: 6 m at the per-metre range) | Partial underpinning like this is far more common than full perimeter |
| Full perimeter, ~30 m semi, mass concrete | £45,000–£78,000 (illustrative: 30 m at the per-metre range) | Rare; only where movement affects the whole footprint |
| Subsidence claim route | Policy excess, commonly around £1,000 | Where buildings insurance covers the subsidence, the insurer funds the works and you pay the excess |
- 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.

Questions, answered directly
How much does underpinning cost per metre?
Typical 2026 quotes: £1,500–£2,600 per metre of wall for traditional mass concrete underpinning, £1,000–£1,800 per metre for resin injection. Depth, access and ground conditions move the number, and London sits at the top of the ranges. Most jobs only need part of the perimeter treated.
How much does it cost to underpin a house in the UK?
Most 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). A rare full-perimeter scheme on a 30 m semi would be £45,000–£78,000 on the same basis. Get quotes for the actual affected length.
Will my insurance pay for underpinning?
If the damage is subsidence and your buildings policy covers it, usually yes: the insurer investigates, treats the cause first, and funds underpinning where the engineer specifies it. You pay the policy excess, commonly around £1,000 for subsidence claims. Tell your insurer before commissioning your own repairs.
Does a house always need full underpinning?
No, full-perimeter underpinning is the exception. Movement usually affects one corner or elevation, and the engineer's scheme targets the affected length. Many subsidence claims never reach underpinning at all: fixing the leaking drain or managing the offending tree resolves the movement.
Do I need building regulations approval for underpinning?
Yes, underpinning is building work under the Building Regulations and needs building control involvement, and underpinning a wall shared with a neighbour is notifiable under the Party Wall etc. Act 1996. The completion certificate and any Certificate of Structural Adequacy are documents future buyers will ask for, keep them.
Is this quote service really free?
Yes, free to you, with no obligation to accept any quote. We pass your details only to relevant local underpinning contractors, who quote you directly; we may receive a fee from those providers, which is how the service is funded.
