Does BB4 8UF flood?

Up to Medium likelihood

Properties in BB4 8UF sit in the Environment Agency's Medium flood-likelihood band (worst property). The band is the worst found in the postcode — it describes the land around properties (defence-adjusted, rivers & sea), not any single address, and not today's conditions.

Low0.1% – 1%00
