Does SG17 flood?

Yes — parts of the SG17 district carry real flood risk: 5 of its 27 at-risk postcodes reach the Environment Agency's High likelihood band. The SG17 postcode district covers Shefford, Clifton, Henlow & Langford, Meppershall & Shillington, close to Arlesey, Biggleswade, Bedford, and surrounding villages in parts of Central Bedfordshire and Bedford.

27 postcodes in the SG17 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 5 high, 3 medium, 19 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
