About this data

Every figure on this page is calculated from the 87 sales HM Land Registry has recorded on William Square since 1995 — what buyers actually paid, not asking prices or estimates. A home that has not changed hands since records began in 1995 will not appear. Sales are matched to this street by postcode and by the street component of the registered address, so a neighbouring street with a similar name is not counted. The Price Paid dataset covers England and Wales only; see Scotland and Northern Ireland.
