About these figures

Price per m²
Median price per square metre of homes sold in the last 12 months (homes with an EPC).
Price change
Median price in the last 12 months against the 12 months before.
Sales a year
Open-market sales in the last 12 months. More sales means a deeper, easier market.
Sales change
Sales in the 12 months to three months ago against the year before. The newest months are left out: Land Registry registers sales late.
Energy efficiency
Average EPC energy efficiency score of homes sold (higher is more efficient).
Carbon
Average carbon emissions of homes sold, tonnes a year. Lower is better.
Station nearby
Median distance from homes sold to the nearest railway station. Closer is better.

Open-market sales from HM Land Registry Price Paid Data in the 12 months to August 2026 (homes in Dorset only); price per m², energy and carbon from the homes sold that have an Energy Performance Certificate. Postcode districts with fewer than 20 sales a year in Dorset aren't ranked.
