Does UB10 flood?

Yes — parts of the UB10 district carry real flood risk: 15 of its 46 at-risk postcodes reach the Environment Agency's High likelihood band. The UB10 postcode district covers Hillingdon West, Hillingdon East, close to Ickenham, Uxbridge, Denham, and surrounding villages in parts of Greater London and Windsor and Maidenhead.

46 postcodes in the UB10 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 15 high, 13 medium, 18 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
