Yes — parts of the CM14 district carry real flood risk: 5 of its 9 at-risk postcodes reach the Environment Agency's High likelihood band. The CM14 postcode district covers Brizes, Stondon Massey & South Weald, Brentwood West, close to Harold Wood, Navestock Heath, Mountnessing, and surrounding villages in parts of Essex and Greater London.
9 postcodes in the CM14 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 5 high, 2 medium, 2 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
