It is not a boundary, and no boundary is drawn. Where marks overlap, the one first in the key is drawn; the counts include every postcode.

Is LN12 at risk of flooding?

435 of the 437 postcodes in LN12 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 3,585 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 435 of 437 postcodes High: 1,453Medium: 2,132Low: 9,294Very low: 374

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.

£205,000 typical price, the 12 months to September 2026
£199,950 12 months to September 2025
  • Detached £237,500 111 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.
