About these figures

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.

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 Sefton 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 Sefton aren't ranked.
