Does PE1 1YY flood?

Peterborough, City of Peterborough

Up to Very low likelihood

Properties in PE1 1YY sit in the Environment Agency's Very 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.

Low0.1% – 1%00
Very lowbelow 0.1%50

Over a 25-year mortgage, a property in a very low-likelihood area has less than a 3% chance of flooding at least once.
