Lowest Flood Risk Postcodes in UK
Postcode sectors in the lowest Environment Agency flood band, in no particular order.
What this ranks on: nothing that separates one sector from another. The Environment Agency extract behind this page places every English sector in the same band, so every score ties and the order below carries no information. Treat it as a list of sectors, not a ranking, and check an address on the official service. It is not a judgement about where is a good place to live, and AreaIQ Places does not score areas.

Questions
Which postcodes in UK have the lowest flood risk?
We cannot answer that from the data we hold, and this page does not try to. The Environment Agency extract behind it places every English postcode sector in Zone 1, which is the value our processing starts from rather than a finding about any particular place, so every sector ties and the order of the list below carries no information. Check a specific address on the Environment Agency service, which is free and current.
How do I check flood risk for a specific property in UK?
Use the official checker at check-long-term-flood-risk.service.gov.uk for England, Natural Resources Wales, SEPA in Scotland, or the Department for Infrastructure in Northern Ireland. Flood risk is assessed per address, not per postcode sector, and a professional flood risk assessment is the right step before a purchase in a lower-lying area.
