Does TN8 flood?

Yes — parts of the TN8 district carry real flood risk: 29 of its 96 at-risk postcodes reach the Environment Agency's High likelihood band. The TN8 postcode district covers Cowden and Hever, Dormansland & Felbridge, close to Edenbridge, Lingfield, Chiddingstone Causeway, and surrounding villages in parts of Kent and East Sussex.

96 postcodes in the TN8 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 29 high, 26 medium, 41 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
