Does MK17 9DB flood?

Up to High likelihood

Properties in MK17 9DB sit in the Environment Agency's High 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%22
Medium1% – 3.3%00
Low0.1% – 1%00
Very lowbelow 0.1%00

Over a 25-year mortgage, a property in a high-likelihood area has at least a 57% chance of flooding at least once.
