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 PO31 at risk of flooding?

54 of the 468 postcodes in PO31 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 458 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 54 of 468 postcodes High: 417Medium: 41Low: 70Very low: 4

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.
