Does TW17 flood?

Yes — parts of the TW17 district carry real flood risk: 62 of its 303 at-risk postcodes reach the Environment Agency's High likelihood band. The TW17 postcode district covers Shepperton Town, Laleham and Shepperton Green, Walton Central, close to Weybridge, Walton-On-Thames, Sunbury, and surrounding villages in parts of Surrey and Greater London.

303 postcodes in the TW17 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 62 high, 103 medium, 138 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
