Is EC3N at risk of flooding?

3 of the 81 postcodes in EC3N 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 3 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 3 of 81 postcodes High: 3Very low: 41

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.

What do homes sell for in EC3N?

Homes in EC3N sold for a typical £490,000 in the 12 months to September 2026, across 5 sales, HM Land Registry's figures show. The 12 months before gave £690,000 from 17 sales. With fewer than 30 sales a year, a change can come from which homes happened to sell, so we do not give one.

£490,000 typical price, the 12 months to September 2026

  • Flat or maisonette £490,000 5 sales

Standard sales of homes at market value. A typical price is the median, the middle sale. Sales take weeks to be registered, so the last month or two are incomplete. Each postcode page gives the figure for its own postcode sector.
