How these figures are calculated. Every sale on this page is a completed transaction from HM Land Registry Price Paid data, registered between 2016 and 2025. We show the median rather than the average wherever there are enough sales, so one unusually high or low sale doesn’t distort the picture. Sales take time to be registered, so the most recent months are provisional. Prices are as recorded and are not adjusted for inflation; a street’s figures reflect the mix of what actually sold there.
