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 SW1P at risk of flooding?

403 of the 752 postcodes in SW1P 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 2 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 403 of 752 postcodes High: 2Very low: 8,650

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.
