About this data

Averages and medians on this page cover the 1,401 sales registered in IP18 since 2015, so they reflect the current market rather than three decades of it. The 4,001 figure is every sale since records begin in 1995, and the yearly chart uses each year's own sales. Prices are what buyers actually paid, as registered with HM Land Registry — not asking prices or estimates. Scotland and Northern Ireland are not in this dataset; see Scotland and Northern Ireland.
