Subsidence risk for 100,000 Londoners

Around 100,000 homes in London face an increased risk of subsidence due to the growing trend of turning front gardens into driveways.
That is according to esure home insurance, which carried out research including a report from the British Geological Society.
The report details how driveways cause rainfall to run off into drains rather than filtering down to the soil where tree roots lay waiting.
As the roots receive no water they move to seek some out, leading to changes in soil moisture beneath foundations.
“It is very appealing for homeowners in busy streets to create a bespoke parking space for their property,” said Nikki Sellers, head of home insurance at esure.
“Unfortunately, for houses with a street tree or large front garden tree nearby this can significantly increase the risk of subsidence.
“A dedicated space may increase the value of your home but subsidence damage will do quite the reverse,” she added.
Homeowners are being warned to do their research before installing a driveway or patio and are advised to take out adequate insurance if they are concerned about subsidence.
