The newest postcodes

A new postcode is often a new street or estate, but Royal Mail also makes new postcodes when it reorganises old ones, so not every one means new homes. Only postcodes still in use are counted.

New homes among the homes sold

PeriodIn West MerseaAcross the CO5 district
The 12 months to September 2026 1 of 88 (1%) 9 of 389 (2%)
The 12 months to September 2025 11 of 123 (9%) 131 of 623 (21%)

Standard sales of homes at market value that HM Land Registry marks as newly built. New homes take longer to be registered than other sales, so the latest 12 months count fewer of them than were sold. A share is given from 5 sales or more.

Homes and businesses in an area at risk, at 23 of 223 postcodes High: 148Medium: 60Low: 50Very low: 2

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.
