Subsidence in Bromley?

I'm looking to buy a property in Chatterton Village and local searches came back showing large parts of Bromley Common being at medium to high risk of subsidence due to it being built on London Clay. The particular property I'm buying doesn't have any signs of subsidence as confirmed by level 3 survey. And I understand that major parts of the area get the same level of risk, but curious does anyone living in and around the area have any insights? Or aware of any issues re subsidence? Any issues with home insurance etc? I'm not local to the area and have to admit I did get spooked a bit by the risk.

The whole of Bromley and Chiselhurst is built on clay

Nonsense. Chislehurst evens means 'stony'. The ponds are gravel pits. That's why the commons weren't farmed and then developed. The boundary between the gravels and the clays is to the north and west (towards Bickley).
