Does SW19 flood?

Yes — parts of the SW19 district carry real flood risk: 13 of its 109 at-risk postcodes reach the Environment Agency's High likelihood band. The SW19 postcode district covers Colliers Wood, Lavender Fields, Wandle, Wimbledon Park, close to Merton, Streatham, Morden, and surrounding villages in parts of Greater London and Surrey.

109 postcodes in the SW19 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 13 high, 19 medium, 77 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
