New homes among the homes sold
| Period | In Southend-on-Sea | Across the SS9 district |
|---|---|---|
| The 12 months to August 2026 | 6 of 2,005 (Under 1%) | 5 of 684 (Under 1%) |
| The 12 months to August 2025 | 11 of 2,525 (Under 1%) | 7 of 844 (Under 1%) |
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.
