INSURANCE GUIDE
Subsidence Insurance UK
What subsidence cover includes, how claims work, and getting insurance after a subsidence history.
TL;DR
- Subsidence is covered under most standard home buildings insurance policies as a named peril.
- Claims can be very expensive - underpinning can cost £10,000-50,000 or more depending on the extent.
- Properties with a subsidence history face higher premiums and some insurers will decline to quote.
- Clay soil areas in South and East England have highest subsidence risk - particularly during dry summers.
What Subsidence Cover Includes
Buildings insurance covers subsidence - downward movement of the ground beneath the foundations - as a standard named peril. It covers the cost of investigating the cause of movement, stabilising the foundations (typically by underpinning or other engineering solutions), and repairing any structural damage to the building. Subsidence claims are among the most expensive in home insurance and can take months or years to resolve while the building is monitored to confirm stability.
Heave and Landslip
Related ground movement perils - heave (upward movement of the ground) and landslip (sideways or downward movement on a slope) - are typically covered alongside subsidence in home buildings policies. All three perils involve ground movement damaging the structure. The cause of movement - tree roots extracting moisture from clay, drought conditions causing clay shrinkage, leaking drains saturating soil, or mining activity - is investigated as part of the claims process.
Tree Root Subsidence
Tree root subsidence occurs when tree roots extract moisture from clay soil, causing it to shrink and the foundations to sink. Mature trees near clay-soil properties are a significant subsidence risk factor. Claims involving tree root subsidence may require the removal of the tree as well as underpinning. Insurance covers the building repair; tree removal costs may or may not be covered depending on whether the tree is on the insured's own land.
Getting Insurance After a Subsidence Claim
A property with a subsidence history - whether the claim was fully resolved or not - can be difficult to insure at standard premiums. The property's previous subsidence must be disclosed on any future application. Some mainstream insurers decline to quote for properties with subsidence histories; specialist insurers and Lloyd's brokers can usually arrange cover at an appropriate premium loading. If underpinning was carried out and is certified as complete and stable, cover is more readily available.

Frequently Asked Questions
How long does a subsidence claim take?
Subsidence claims are typically among the slowest to resolve in home insurance because of the monitoring period required to confirm that movement has stabilised before repairs are undertaken. Monitoring periods of 12-24 months are common. The total claim lifecycle - from notification to final repair completion - can take two to four years for significant subsidence events. The insurer manages the engineering investigation and repair process throughout.
Will subsidence claim affect my premium when I renew?
Yes. A subsidence claim will typically result in a significant premium increase at renewal and possibly in the insurer declining to renew at all. The claim history must be disclosed to any new insurer. Specialist insurers who underwrite subsidence-affected properties can often provide continued cover, though at a premium that reflects the increased risk profile of a property with a subsidence history.
