Percentage of Property Treated (POPT) was introduced under ECO2t in order to calculate the carbon or cost savings where a measure is only installed to part of a property. We have decided to carry out this survey on POPT to understand if there are difficulties with calculating POPT and if so, to establish what they are and to consider whether there is a significant impact on the scheme, and what actions, if any, might be required.

This survey forms part of a broader POPT research project that has two other elements: analysis of technical monitoring results and analysis of information relating to POPT received by Ofgem (such as via queries). We will review the information received as part of the POPT research project during October and we will publish the outcome of the review. 

The survey will be open for responses from 31 August 2017 to midnight 30 September 2017.

We have provided a template to help us collate responses. Responses and queries should be directed to Alternatively, please provide written responses to:
