Does HP7 flood?

Yes — parts of the HP7 district carry real flood risk: 7 of its 31 at-risk postcodes reach the Environment Agency's High likelihood band. The HP7 postcode district covers Amersham & Chesham Bois, The Missendens, close to Little Missenden, Chesham, High Wycombe, and surrounding villages in parts of Buckinghamshire and Hertfordshire.

31 postcodes in the HP7 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 7 high, 4 medium, 20 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
