Where does this data come from?

The property price data for England and Wales that you see on our website is sourced primarily from HM Land Registry's Price Paid Data. This dataset is the one source of truth for most of the country’s residential property transactions. Where available, we’ve enhanced this with information gathered from Energy Performance Certificate (EPC) data and then further added to it with records from various trusted additional sources. This material was last updated on October 7, 2024.

Some of the figures you see above, such as the Value Potential score are constructed using our own proprietary algorithmic modelling. They are most decidedly estimates, and may be off the mark. Please use this information cautiously, and as a guide only. If in doubt, and certainly before putting in an offer anywhere, please speak with your local estate agent to get a better understanding of the property’s valuation.
