Median sold price per street over the last five years, HM Land Registry Price Paid Data (standard market sales; streets with at least 5 recorded sales). £/m² is the street's median of sold price ÷ EPC floor area, shown where at least three sales match an EPC — the like-for-like measure that separates big homes from expensive ones. Street-level medians move with what happens to sell — treat them as a robust guide, not a valuation of any home.
