Does EN6 flood?

Yes — parts of the EN6 district carry real flood risk: 20 of its 34 at-risk postcodes reach the Environment Agency's High likelihood band. The EN6 postcode district covers Bentley Heath & The Royds, Potters Bar Parkfield, Potters Bar Furzefield, Potters Bar Oakmere, close to South Mimms, Water End, Cockfosters, and surrounding villages in parts of England and Hertfordshire.

34 postcodes in the EN6 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 20 high, 3 medium, 10 low, 1 very low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
