Yes — parts of the GU24 district carry real flood risk: 36 of its 64 at-risk postcodes reach the Environment Agency's High likelihood band. The GU24 postcode district covers Windlesham & Chobham, Normandy & Pirbright, Bisley & West End, Horsell, close to Chobham, Mayford, Old Woking, and surrounding villages in parts of Surrey and Hampshire.
64 postcodes in the GU24 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 36 high, 12 medium, 16 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
