Does KT6 flood?

Yes — parts of the KT6 district carry real flood risk: 11 of its 48 at-risk postcodes reach the Environment Agency's High likelihood band. The KT6 postcode district covers Tolworth, Surbiton Hill, St Mark's & Seething Wells, Long Ditton, close to Kingston Upon Thames, Worcester Park, East Molesey, and surrounding villages in parts of Greater London and Surrey.

48 postcodes in the KT6 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 11 high, 13 medium, 24 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
