Does S1 flood?

Yes — parts of the S1 district carry real flood risk: 10 of its 68 at-risk postcodes reach the Environment Agency's High likelihood band. The S1 postcode district covers City, close to Sheffield, Sheffield Meersbrook, Sheffield Carr Brook Screen, and surrounding villages in parts of South Yorkshire and Derbyshire.

68 postcodes in the S1 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 10 high, 4 medium, 54 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
