Does SE7 flood?

Yes — parts of the SE7 district carry real flood risk: 3 of its 52 at-risk postcodes reach the Environment Agency's High likelihood band. The SE7 postcode district covers Greenwich Peninsula, close to Charlton, Silvertown, Hither Green, and surrounding villages in Greater London.

52 postcodes in the SE7 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 3 high, 49 very low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
