Property Data without individual data

Parity Projects and Ecofurb collect and process data about homes in the UK in the following ways. The personal data of the individuals associated with a property is not accessible. Therefore, any ‘subject access request’ (if you ask us to send you the data we hold about you) will not include this data. 

Information about homes in the UK. 


We get this information from:

  • Energy Performance Certificate Data. You can read about this here
  • Ordnance Survey Data
  • LIDAR data

We also try to improve this information by using data from nearby houses and visual surveys. 

Information about properties collected when home surveys or works are carried out.

We hold information about your property in software produced by Parity Projects. We update this information when we collect data during a survey and in future may do this when you have work done. We use this data to help us and others build a better picture of the energy efficiency of houses in the UK.

Information in this software is available to Parity Projects, to RetrofitWorks and certain members of the RetrofitWorks Cooperative, and to new users of Plan Builder. 

It is also available to clients of Parity Projects who pay for a licence: clients are for example local councils, other public sector organisations, and retrofit professionals. The licence only permits use of data for the purposes of energy efficiency advice provision and programme development and delivery. This allows us to offer and improve software which helps councils and others to plan and promote energy efficiency and carbon emissions reduction from homes.

Aggregate data, statistics and analysis eg estimated carbon savings from Ecofurb projects.  

We plan to use aggregate data and statistics about works carried out by Ecofurb to publish and share.
