Summary
The Code Manager is required to perform an annual review of a number of PAF items, including the PARC. The PARC has already been updated several times over the course of 2025 through a series of REC Changes (including R0173, R0202, R0254, R0259). We have conducted an end-to-end review and have identified the other changes are required.

Problem Statement
To ensure REC Parties and Service Providers are aware of reports they must provide for Performance Assurance as well as reports obtained from central data sources (such as, but not limited to, the DIP Manager) used in assuring their performance within the market. It is essential these reports are maintained in line with changes to Code processes as well as changing risk landscape.

Summary
20.4 of Schedule 5 Change Management currently states "decisions of the relevant responsible sub-committee shall be made by a majority vote". This is factually incorrect as the Metering Expert Panel is subject to different voting arrangements.

Problem Statement
There are many Parties who have acceded to the REC but not Qualified within 12 months of accession, and who have not contacted the Code Manager within 6 months. This may cause confusion for Parties in knowing which other organisations have Qualified for roles under the REC.

No
Latest Update
08/11/2024 - This Change Proposal has been implemented as part of the November 2024 REC Release.
Summary
This is a Housekeeping Change Proposal subject to the Housekeeping Change Proposal process, rather than the standard Change Process. The nature of the change is that it makes non-material changes to the REC Products to correct typographical, grammatical or consistency errors, and provides an opportunity to introduce necessary clarifications. This change proposal is looking to fix an error identified with R0206 Cross code change to align with BSC CP1598. BSC CP1598 was raised to add six scenario variants to four Market Messages that have been identified as missing. The REC Energy Market Data Specification contains a number of Market Message scenario variants used in BSC processes. This REC Change Proposal has been raised to align with CP1598 and ensure these scenario variants are added to the REC Data Specification. The legal text for R0206 approved at Change Panel on 15 October 2024, had a change to one of the scenario variants (SV00474) that was not clear as it was not red lined. The change was to the owner of the scenario variant from the Retail Energy Code Company (RECCo) to the Balancing and Settlement Code Company (BSCCo). The red lining for SVcccc was also incorrect as it deleted RECCo as the owner when in fact it is a new scenario variant so no previous owner. The owner as BSCCo that was approved, is correct.

Problem Statement
As these Scenario Variants are not captured in the Data Specification, the relevant Market Participants won’t be able to use the Data Transfer Network (DTN) to exchange the relevant data, which would result in them having to use a less secure mechanism to send and receive data. This means the original intent of Elexon Modification P375 has yet to be achieved as not all Market Message changes have been implemented.

Creation of a Tool to Manually Correct ERDS / CSS Discrepancies

Priority

No
Latest Update
This Change Proposal was implemented on 27 March 2026.
Summary
There is currently a tool utilised by DNOs to manually correct registration data to align the Registered Supplier in ERDS with the data held in CSS. The Market-Wide Half Hourly Settlement (MHHS) Design does not allow for retrospective amendment of Supplier Registration i.e. there is no equivalent tool for manual correction post MHHS go live (M10). Therefore, post MHHS implementation, any issues which prevent CSS data being reflected in ERDS cannot be corrected. This will prevent the Supplier from appointing agents and will lead to errors in settlement data under the BSC. A change is required to address this.

Problem Statement
There are instances where ERDS (and SMRS under BSC governance) can be misaligned with the CSS and under the MHHS arrangements there is no mechanism for manual correction which there is in place today. From MHHS go live the Supplier will not be able to appoint their preferred agents. This issue only applies to MHHS Migrated Metering Points as the existing mechanism for manually correcting data would be used if the issue related to a non-migrated Metering Point. In the event that the Supplier cannot appoint its agents, this may prevent the Supplier from accurately billing the Consumer. The potential impact will increase as MHHS Migration continues, with more MHHS Metering Points potentially impacted by any CSS / ERDS discrepancy.
