Does KT4 flood?

Yes — parts of the KT4 district carry real flood risk: 13 of its 33 at-risk postcodes reach the Environment Agency's High likelihood band. The KT4 postcode district covers Cuddington, North Cheam, Motspur Park & Old Malden East, close to Worcester Park, New Malden, Tolworth, and surrounding villages in parts of Greater London and Surrey.

33 postcodes in the KT4 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 13 high, 2 medium, 18 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
