Our property valuation model calculates the latest property prices using data from trusted external sources in combination with available user-submitted information - this includes HM Land Registry which is the UK's official register for ownership of land and property in England and Wales.
The model takes into account what has sold, when and how prices have changed over time. It also brings in multiple datasources to cross reference accuracy with the latest sales data and cost per square foot benchmarks.
In addtion to this, we filter out bad data where we are able to identify it so we can improve accuracy.
If home improvements have been made or the property has been extended after it was last purchased, these improvements won't be taken into account if we don't know about them. For properties that have had home improvements made, you can get an updated valuation here.
By utilising HM Land Registry data we're able to provide deep insights into how property prices have changed over time to better predict what a property is worth today.
