The BGS GeoSure insurance product gives an index-level assessment of the potential for a geological deposit to create financial insurance loss due to natural ground movement.

It incorporates the combined effects of the six BGS GeoSure hazards on (low-rise) buildings and links these to a postcode database (the derived postcode database). This database contains a normalised hazard rating for each of the six BGS GeoSure themes hazards (i.e. each BGS GeoSure theme has been balanced against each other) and a combined unified hazard rating for each postcode in Great Britain.

A series of geographical information system (GIS) maps show the most significant hazard areas. The ground movement, or subsidence, hazards included are:

  • landslides
  • shrink-swell clays
  • soluble rocks
  • running sands
  • compressible deposits
  • collapsible deposits
