The postcodes at high risk

Beside each: how many of its homes and businesses the Environment Agency puts at that risk.

Ofcom gives each postcode's share of homes and businesses, not how many there are, so these count postcodes. Each postcode page has its own figures. A provider's checker answers for one address.

Is CO2 at risk of flooding?

45 of the 944 postcodes in CO2 have a home or business in an area at risk of flooding from rivers or the sea, the Environment Agency says. At those, it puts 81 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 45 of 944 postcodes High: 61Medium: 20Low: 83Very low: 1,058

High: 3.3% or more a year (1 in 30). Medium: 1% to 3.3% a year. Low: 0.1% to 1% a year. Very low: under 0.1% a year (1 in 1,000). Each band is the chance of flooding in any one year.

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.
