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 Lambeth 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 Lambeth aren't ranked.
