Homes and businesses in an area at risk, at 11 of 771 postcodes High: 8Medium: 6Low: 10

Homes and businesses in an area at risk of flooding from rivers or the sea, as the Environment Agency counts them, added up over the postcodes. It is for the land, not each building, and leaves out surface water, groundwater and sewers. Each postcode page has its own figures and its flood warning areas.
