The short answer

You can buy a house with a subsidence history if it has been properly repaired, has a clean post-works monitoring record and remains insurable, ideally with the existing insurer willing to continue cover. Past subsidence is not automatically disqualifying, but unresolved or repeatedly recurring movement, or a property you cannot insure, is a serious red flag.

The real risk

Subsidence is downward ground movement that causes a building to crack and distort, most often from shrinkable clay soils drying out, nearby trees, leaking drains or former mining. Once a property has had a claim, insurance can become harder and more expensive, and you may be tied to the existing insurer.

The critical question is not 'did it move?' but 'was it fixed and has it stayed still?'. A property underpinned years ago with a clean monitoring record and a structural-engineer sign-off can be a sound, well-priced buy. Active or recurring movement is a different matter.

A subsidence history must be disclosed by the seller, and a buildings survey (RICS Level 2 or 3) is strongly advised to assess the current condition.

What the data reveals

British Geological Survey GeoSure

Shows shrink-swell clay and other ground-stability hazards for the area, the underlying cause of most non-mining subsidence.

Environmental/ground-stability search

Flags collapsible ground, made ground and mining alongside natural shrink-swell risk.

Seller disclosure + insurance history

Past claims, underpinning records and the existing insurer's willingness to continue cover are decisive.

RICS building survey

Assesses current cracking, movement and whether past repairs are holding.

How to check this exact address

  1. 1Check the property's ground-stability flags (shrink-swell, mining) in a HouseCheckup report before you offer.
  2. 2Commission a RICS Level 2 or Level 3 survey to assess current structural condition.
  3. 3Ask the seller for underpinning records, structural-engineer reports and the claims history.
  4. 4Confirm you can obtain (and ideally continue) buildings insurance on the address.

Frequently asked questions

Is a house with past subsidence a bad buy?
Not necessarily. If it was properly underpinned or repaired, has a clean monitoring record and remains insurable, it can be a sound purchase, often at a discount. Active, recurring or unrepaired movement is the real concern.
Can you insure a house that has had subsidence?
Often yes, but premiums and excesses can be higher, and you may need to stay with the existing insurer or use a specialist. Confirm insurability on the specific address before committing.
Does subsidence have to be disclosed when selling?
Yes. Sellers must disclose known subsidence and past claims on the Property Information Form. Failing to do so can give rise to a misrepresentation claim.
