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.

Postcodes where every home can get gigabit337 of 514
Postcodes where every home can get superfast491 of 514

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 N20 at risk of flooding?

1 of the 536 postcodes in N20 has a home or business in an area at risk of flooding from rivers or the sea, the Environment Agency says. At those, it puts 4 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 1 of 536 postcodes High: 2Medium: 2Low: 2

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.
