Does SE4 flood?

Yes — parts of the SE4 district carry real flood risk: 7 of its 17 at-risk postcodes reach the Environment Agency's High likelihood band. The SE4 postcode district covers Crofton Park, Ladywell, close to Catford, Hither Green, Grove Park, and surrounding villages in Greater London.

17 postcodes in the SE4 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 7 high, 3 medium, 7 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
