London

With the country getting hotter, the ground underneath most houses in London will be drying out and becoming softer due to clay soil shrink-swell, leading to a massive increase in insurance claims for subsidence.

No one will want to buy a house with known subsidence because insurance normally only covers repairs for subsidence if it wasn't mentioned in the original survey report.

This is going to mean a huge reduction in houses prices all around London as they try to offload their houses that will need remedial action undertaking to prevent damage to the house.

This page shows a map of how London is going to be affected.

Most susceptible are properties in the highly-populated London areas, particularly in northern and central London boroughs, and Kent in the South East. Projections suggest that the number of properties in London likely to be affected by climate will rise from 20 per cent in 1990, to 43 per cent by 2030, and almost 3 times 1990 values (57 per cent) by 2070.
