Does SW1W flood?

Only lower-likelihood flood risk is recorded in SW1W: none of its 45 listed postcodes goes beyond the Low band. The SW1W postcode district covers Knightsbridge & Belgravia, Pimlico North, close to Westminster, Tower Pier, Barnes, and surrounding villages in England.

45 postcodes in the SW1W district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 45 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).
