Each mark is a postcode's centre point as ONS gives it, not a building. Press one to see its postcode and open its page. No boundary is drawn. Where marks overlap, the one first in the key is drawn; the counts include every postcode. Names in italics are council wards: we hold no town or village names here.

Is CH45 at risk of flooding?

49 of the 758 postcodes in CH45 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 113 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 49 of 758 postcodes High: 96Medium: 17Low: 11Very low: 598

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.
