About this data
Averages and medians for Isleworth cover the 2,850 sales registered since 2020, so they describe the current market rather than three decades of it. The 18,073 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.
