Latest Update
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.

This Change Proposal has been implemented as part of the June 2026 REC Release.
Summary
Elexon have raised CP1622 to amend the Validation rules within the Supplier Meter Registration Service (SMRS) for the Number of Register Digits Data Item within the IF-005 Market Message, to allow digit values from 1–9, ensuring accurate data and reducing exceptions. There are no Validation rules related to the D0312 Market Message which need to be amended under the Balancing and Settlement Code (BSC), but the D0312 itself contains a Data Item Rule regarding the Number of Displayed Register Digits which needs to be amended in line with CP1622.

Problem Statement
BSC CP1622 is looking to address that SMRS cannot accurately update the Number of Displayed Register Digits for a SMETS2 Smart Electricity Meter due to Validation rules currently in place. The Validation rules proposed to be amended are those on the IF-005, which has direct impacts to the D0312.

12/05/2026 - The Code Manager have developed a solution which has been live since 05 May 2026. More detail can be found on the REC Portal Wiki. A Closure Report has now been published, and this Issue has now been classed as resolved.
Summary
The RegistrationId (DI90043 / DI849) is required by SMRS to be included in the IF-031 'Supplier Agent Appointment Request' Market Message to allow the SMRA to process the appointment request. However not all Suppliers hold the RegistrationId for all Meter Points, in particular those that have not undergone a Registration managed by the Central Switching Service (CSS)

Proposed solution summary
- As part of the solution for REC Issue I0296 - Registration Id Required for MHHS Appointments the REC Code Manager have developed a process to provide Energy Suppliers the Registration Id for Metering Points that have not been through a Central Switching Service (CSS) Registration Managed Switch. This is to allow Energy Suppliers that may not hold the Registration Id for these Metering Points to populate the Market-wide Half Hourly Settlement (MHHS) Agent Appointment Messages required to initiate a MHHS Migration.
- More detail of the solution can be found: https://recportal.co.uk/rec-wiki-mhhs/-/knowledge_base/market-wide-half-hourly-settlement/provision-of-registration-id-required-for-mhhs-appointments?utm_source=emailoctopus&utm_medium=email&utm_campaign=Weekly%20Bulletin%20-%202026-05-01

Problem Statement
Not all Energy Suppliers hold the RegistrationId for all Meter Points, particularly those Meter Points that have not gone through a Switch, i.e. have not undergone a Registration managed by the CSS. The RegistrationId is currently only available where a Metering Point has been through a CSS managed Registration. Without the RegistrationId available to Energy Suppliers, not all Metering Points will be able to migrate putting the MHHS Migration and Milestone M15 at risk.
