Check a postcode’s flood risk

Enter a postcode to see the Environment Agency's rivers-and-sea flood risk band for that area. It is an area-based, indicative reading, not a survey of one property; confirm on the official checker before you rely on it.

Free, no sign-up. Indicative and area-based, with the official checker linked on every result.

What the band means

One of four bands for the area around that postcode, with what the band actually means in chance-per-year, and a link to the official checker. A postcode outside England is sent to its own nation’s flood map rather than given a band it does not have.
