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. Names in italics are council wards: we hold no town or village names here.

Is CO8 at risk of flooding?
23 of the 126 postcodes in CO8 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 53 homes and businesses in an area at high or medium risk.
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 CO8?
Homes in CO8 sold for a typical £373,500 in the 12 months to September 2026, across 25 sales, HM Land Registry's figures show. The 12 months before gave £475,000 from 37 sales. With fewer than 30 sales a year, a change can come from which homes happened to sell, so we do not give one.
- Detached £607,500 6 sales
- Semi-detached £335,000 10 sales
- Terraced £271,250 8 sales
- Flat or maisonette 1 sale, too few to price
Each bar is that kind's typical price, against the most expensive kind here.
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.
