Practical guidance on how to approach and provide effective coverage in the event of subsidence. 

Subsidence occurs when there is a downward movement of ground underneath a property, causing the foundations to become unstable. The result of this is structural damage such as cracks in the walls, floors and ceilings. It is an issue known to increase when there are long spells of dry and hot weather.



With temperatures rising in the UK, more hot summers are expected. This will also have an impact on more properties as well as existing claimants. There will be a greater need to investigate and action cases of subsidence, as well as preventing subsidence from reoccurring.


To help underwriting professionals provide subsidence coverage, this Good Practice Guide examines the following:

  • what causes subsidence
  • how to identify subsidence
  • how subsidence is covered
  • how to underwrite subsidence
  • how subsidence claims are investigated
