About this data
Averages and medians on this page cover the 1,891 sales registered in RM20 since 2015, so they reflect the current market rather than three decades of it. The 4,540 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.
