Does BB2 2SQ flood?

Up to Low likelihood

Properties in BB2 2SQ sit in the Environment Agency's Low 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.

Likelihood bandAnnual chancePropertiesOf which homes
Highgreater than 3.3%00
Medium1% – 3.3%00
Low0.1% – 1%11
Very lowbelow 0.1%22

Over a 25-year mortgage, a property in a low-likelihood area has a 2–22% chance of flooding at least once.
