Sold-price trend (1995–2026)
Annual sold price in HP4 1, 1995–2026 — mean (blue) and median (terracotta). The median is the typical sale; a wide gap to the mean means a few high-value sales pull the average up. 2026 is a part year (19 sales so far). Hover a point for both figures. Source: HM Land Registry Price Paid.
