Does EN1 flood?

Yes — parts of the EN1 district carry real flood risk: 1 of its 24 at-risk postcodes reach the Environment Agency's High likelihood band. The EN1 postcode district covers Bush Hill Park, Bullsmoor, close to Winchmore Hill, Edmonton, Enfield Wash, and surrounding villages in parts of England and Hertfordshire.

24 postcodes in the EN1 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 1 high, 23 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).
