The Zoopla estimates are our opinion of the market values of homes and are based on a large number of data points relating to property sales, value trends and home characteristics through the UK, including publicly available data such as that from HM Land Registry and Registers of Scotland

We upgraded our house price estimates, based around changes to the algorithm which our Zoopla estimates are generated from. Our Automated Valuation Model (AVM) is powered by Hometrack, and this model gives you a more accurate picture of property prices with even better coverage of homes across the UK. When we changed from the old model to our AVM, it was natural that the house price estimates would change, with some increasing or decreasing and others being withdrawn.

  • We aim to maintain the accuracy and integrity of our AVM; therefore, we are unable to change the information. New data cannot be manually fed into the AVM, not by users, nor by ourselves.
    However, if you can provide us with historical evidence and we can see there is an inconsistency in the current estimate for your home, as a resolution we can suppress your current estimate from displaying on our live website and it will appear as Not known/No estimate available as a result, until we are able to reinstate it

If you would like to contact Customer Support regarding the suppression of this data, you can either email, or, click Submit a request below and complete the contact form.


  • Please note that we will not be able to provide you with a timeframe for when an estimate reinstatement will take place. In the meantime, this will allow for the analysis of further data points and modification to the estimate
  • Our estimates are not formal valuations. We advise you contact an estate agent or surveyor for a more accurate valuation, as they can conduct a visit. Contact a local agent here
