Does SW1H flood?

Only lower-likelihood flood risk is recorded in SW1H: none of its 84 listed postcodes goes beyond the Low band. The SW1H postcode district covers St James's, close to Westminster, Tower Pier, Barnes, and surrounding villages in Greater London.

84 postcodes in the SW1H district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 84 very low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
