Are new homes being built in Cardiff?
239 of the 7,283 postcodes now in use in Cardiff came into use in January 2020 or later, ONS says. In the 12 months to August 2025, 56 of the 4,262 homes sold in Cardiff were newly built (1%), HM Land Registry's records show; across the CF14 district, 7%.
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 Cardiff | Across the CF14 district |
|---|---|---|
| The 12 months to August 2026 | 2 of 3,363 (Under 1%) | 11 of 861 (1%) |
| The 12 months to August 2025 | 56 of 4,262 (1%) | 80 of 1,125 (7%) |
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.

A mile is a wide circle: in a town it takes in the centre and its shops, where much crime is recorded.
