The GL18 postcode district covers Newent & Taynton, Dymock, Hartpury & Redmarley, Penyard, close to Highleadon, Bromsberrow, Sandford Bridge, and surrounding villages in parts of Gloucestershire and Herefordshire.

28 postcodes in the GL18 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 16 high, 5 medium, 7 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
