Non-Domestic Change of Occupier Reporting (R0155 Solution)
Summary
As part of the R0155 change process, the REC Performance Assurance Board requested ongoing monitoring reporting to identify outliers or anomalous behaviour which the Code Manager would then follow up in detail. However, this planned reporting by Energy Suppliers was descoped from R0155 due to the ongoing development of an Ofgem Reporting Request for Information (titled Non-Domestic Market Monitoring Request for Information). The Ofgem RFI includes data received from Energy Suppliers on the time taken for a Non-Domestic Consumer’s request, and to simplify the process for Energy Suppliers, REC Performance Assurance intend on using the same data. This reduces the need to make two related, but different reports in the same topic areas. The Code Manager intended to use the reporting from the Ofgem RFI for ongoing Performance Assurance monitoring of the Non-Domestic Change of Occupier process. However, this was not confirmed by Ofgem in time for the R0155 implementation, as such a separate REC Change Proposal is required to include this data as part of the ongoing Performance Assurance monitoring.

Problem Statement
The planned reporting by Energy Suppliers was descoped from R0155 due to the ongoing development of an Ofgem Reporting Request for Information (titled Non-Domestic Market Monitoring Request for Information). Without the Ofgem RFI data being submitted, or an alternative means of receiving or reporting Non-Domestic Change of Occupier data, REC Performance Assurance are unable to complete the ongoing monitoring activity originally requested by the Performance Assurance Board during the R0155 change process.
Proposed solution summary
- Incorporating the Ofgem Reporting RFI Non-Domestic Change of Occupier data into the Performance Assurance Reporting Catalogue
- Development of a process to agree data sharing between Ofgem and the REC Code Manager to share allow Ofgem to share the Non-Domestic Change of Occupier data directly with the Code Manager to reduce the burden on Energy Suppliers and save them from having to duplicate submissions
