21/07/2026 - On 21 July 2026, the REC Change Panel voted to approve the Change Report (Proposal Plan) for I0325.
Summary
The REC was updated, primarily through R0209 and R0241, to add requirements that support the transition to, and enduring operation of the MHHS arrangements. As part of the transition, each impacted Metering Point will be migrated using processes defined in Codes, including the REC. Once this migration activity is complete, the legacy and transitional arrangements will become redundant and should be removed from the REC to support its efficient operation

Problem Statement
Retention of redundant obligations within the REC would make it more complex to navigate for Market Participants and could cause confusion on the obligations that are in effect to support the efficient operation of the Great British Energy retail market. It is also worth noting that until Ofgem formally closes the MHHS Significant Code Review (SCR), this REC Issue could potentially impact that SCR.

Latest Update
04/08/2023 - Change Proposal has been withdrawn as agreed with the Proposer. The Problem Statement was addressed through C3-0047 - Updates to PAB Procedures.
Summary
Within Schedule 19 – Market Exit and Supplier of Last Resort there is currently no consideration of circumstances where the Replacement Supplier is unable to fulfil its REC obligations in respect of Consumers transferred to them, due to them having little or no control over the processes of the failed supplier or it’s administrator. This change seeks to define when the Replacement Supplier is responsible for obligations relating to the Consumers gained through a Supplier of Last Resort (SoLR) Process.

Proposed solution summary
- As a Consumer when my Energy Supplier goes out of business and I am transferred to a Replacement Supplier, I want my supply transfer to be handled quickly and have confidence that my new Supplier has all the necessary data to set up my account and bill me correctly from the transfer date, and if the Replacement Supplier fails to provide the expected level of service they will be appropriately held accountable.
- As a Replacement Supplier, I want the limitations affecting my ability to meet my REC obligations to be understood by the REC Code Manager and the Performance Assurance Board, so that any breaches of obligations are considered fairly and any limitations are taken into consideration.
- As the Code Manager I want to apply appropriate and proportionate Performance Assurance Techniques, taking in to account the ability of a Replacement Supplier to meet their obligations under the REC.

Problem Statement
Currently, Replacement Suppliers are responsible for all obligations of the failed supplier from the date and time set out in the Last Resort Supply Direction, this includes a period of time prior to Consumer accounts transferring to the Replacement Supplier’s systems, limiting their ability to fulfil these obligations. This means that a Replacement Supplier may experience issues with the Performance Assurance obligations for which they are responsible, but do not have direct control over. Any breaches of obligations by a Replacement Supplier need to be considered fairly and any limitations the Replacement Supplier may face are taken into consideration.
