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 YstradgynlaisAcross the SA9 district
The 12 months to September 2026 5 of 39 (13%) 5 of 153 (3%)
The 12 months to September 2025 29 of 70 (41%) 35 of 207 (17%)

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.
