On 07 August 2026, Ofgem approved this Change Proposal, in line with the recommendation made by the Code Manager and the Metering Expert Panel. R0207 will be implemented on 06 November 2026. Ofgem's decision can be found here: https://www.ofgem.gov.uk/publications/r0207-retail-energy-code-rec-proposed-changes
Summary
BSC Mod 459 and REC CP R0144 were raised to allow different MOAs to be appointed for the import and export MPANs on a shared meter. One of the justifications for this was to stop export suppliers being charged inflated rates. Both changes have been placed on hold due to the MHHS Programme so this change has been raised to specifically resolve the charging issue.

Problem Statement
Where the same electricity Metering Asset is being used for the measurement of Import and Export for more than one Metering Point, the Export MOA must be the same as the Import MOA. This may result in uncompetitive charging by the MOA, as the Export Supplier has no choice in their appointment.

Latest Update
This Change Proposal was implemented as part of the 7 November 2025 REC Release.
Summary
As part of the MHHS REC code change activity, a change has been made to REC Schedule 30 to remove the half hourly meter exemption from the Erroneous Transfer provisions. Whilst this is necessary from an MHHS perspective with all sites becoming half hourly settled, the application of ET obligations in the Advanced Meter segment creates some additional challenges. To be able to accurately bill an Advanced Meter site, following repatriation of that customer to their correct supplier after an ET has been raised / agreed, the supplier needs to have access to half hourly consumption data for the ET period when they were not the registered supplier. With ETs potentially taking up to 2 years to be identified and resolved, the only place that the supplier could reliably source that HH consumption data would be from the other (losing) supplier.

Proposed solution summary
- An approval of this Issue/Change Proposal would see an obligation placed upon the Losing Supplier, following a successful Erroneous Switch repatriation, to provide the Gaining Supplier with the Half-Hourly consumption data for the period in which they were erroneously supplying the meter.
- Half-Hourly consumption data would be providing to the Gaining Supplier, from the Losing Supplier, via SDEP using an Excel template within 5 Working Days of the Erroneous Switch repatriation switch date. The Gaining Supplier would be required to provide 48 Half-Hourly consumption intervals for each that the the Consumer was supplied by the erroneously Gaining Supplier.

Latest Update
08/11/2024 - This Change Proposal has been implemented as part of the November 2024 REC Release.
Summary
There is currently a mismatch within the Central Switching Service (CSS) system functionality and the legal text within the REC Switching Data Management Schedule. Within the schedule the retry strategy is defined as “retry sending the Market Message at intervals of 10 seconds, 20 seconds and 30 seconds from each attempt to send the Market Message. If these retry Market Messages also fail, then the Market Message shall be retried at intervals of one hour up to a maximum of 12 hours; after which delivery of the Market Message shall be abandoned and a Switching Incident raised in accordance with the Switching Service Management Schedule”. However, in response to an incident in 2022, the CSS Provider updated the retry strategy. This change seeks to amend the legal text in Section 2.4 of the Switching Data Management Schedule to reflect the retry strategy which is currently in operation in the CSS system.

Proposed solution summary
- The Switching Data Management Schedule Section 2.4 should be updated to reflect the current retry strategy: 1. a short interval retry sequence of 3 attempts at 20 second intervals 2. a long interval retry sequence of 12 attempts at 1 hour intervals. The CSS Provider has confirmed that there is now a process in place that would prevent any future updates to the retry strategy without a change request being raised in the first instance.

This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
Studies conducted by the REC Performance Assurance (RPA) function of the REC Code Manager have concluded that gas market data fidelity may be improved by reducing the frequency of missed messages between Metering Asset Managers and other REC Parties. This Issue seeks to explore mechanisms by which a reduction in the number of permissible communication methods used by MAMs could support the data quality improvement objective.

Problem Statement
MAMs communicate with each other, and with other parties, using up to three possible methods as they send Market Messages in line with their obligations in the REC. It has been suggested that moving to a single communication method might help mitigate gas data quality issues. This Issue seeks to explore an interim solution to facilitate this.

Problem Statement
There is no time scale by which Energy Suppliers need to have submitted the Registration De-Activation Request or for electricity to have raised a query with the Distribution Network Operator (DNO) if they believe the Metering Point should not be Disconnected. This raises difficulties for the REC Performance Assurance team when monitoring and enforcing this obligation.

Summary
The drafting in Schedule 28 – Related Metering Points has been updated for Market-wide Half Hourly Settlement (MHHS), allowing related Metering Points to be in a Status of Operational or Created in MPRS, as long as all Related Metering Points are in the same Status. This Change Proposal suggests allowing Secondary Metering Points with a Status of Created to be linked to Primary Metering Points with a Status of Operational, for MHHS migrated Metering Points only.

25/03/26 - the Change Report (Final Recommendation) has been approved by the Technical Expert Panel for implementation on 06 November 2026. The appeal window has now closed.
Summary
Many Switching Incidents are on hold waiting for resolution. The Switching Operator puts these tickets on hold, which is an approved business process from the Switching Programme. This is not reflected in the obligations on SDSPs or other REC Service Providers, where there is no on hold concept. Further there are no obligations on CSS Users to respond in a timely basis. This means that the REC obligations do not reflect current practice, and many tickets remain open much longer than necessary.

No
Latest Update
This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
This issue has been raised proposing to establish a limit on the number of queries permitted within a single Application Programming Interface (API) call. As there is potential for performance degradation and system instability that can occur when a large number of queries are made in a single API call to the Electricity Enquiry Services (EES) API. The aim would be to prevent overwhelming the system and ensure consistent response times and reliability. Therefore, this proposes implementing a limit of 1000 queries per single API call.

Problem Statement
The absence of a limit on the number of queries (batch processing) within a single API call could cause performance issues and system instability. As a result, system responsiveness may degrade when a large number of queries are made in a single call, impacting user experience and hindering the ability of the EES API to consistently meet user demands.
