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
| Period | In Seaham | Across the SR7 district |
|---|---|---|
| The 12 months to August 2026 | 0 of 251 (0%) | 0 of 328 (0%) |
| The 12 months to August 2025 | 0 of 274 (0%) | 41 of 425 (10%) |
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.

Is Seaham at risk of flooding?
4 of the 547 postcodes in Seaham 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 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.
