Which postcodes in South West have the lowest flood risk?
Flood zone data comes from the Environment Agency (for England). Zone 1 means less than 0.1% annual chance of flooding — this is the lowest risk designation. The postcodes below are all in Zone 1. Note: flood zones can change as new modelling is done or defences are built. Always commission an independent flood risk assessment before buying a property, particularly in lower-lying areas.
How do I check flood risk for a specific property in South West?
AreaIQ shows sector-level flood zone data. For a specific address or property, use the official Environment Agency flood risk checker at gov.uk/check-flood-risk or commission a professional flood risk assessment report.
