An Update to Plan has been approved by the REC Technical Expert Panel on 25 June 2026.
Summary
The Meter Manufacturers Make and Type (J0410 / DI-048) was not populated as part of the MHHS Programme's data cleanse. However it is part of the SMRS maintained Meter Technical Details (MTDs) for Smart Meters which replace the DTC MTD Market Messages for Smart Meters in the MHHS environment. It is not currently possible to populate this item in the legacy arrangements.

Problem Statement
Following MHHS Migration, the MTDs provided by SMRS do not include the Meter Manufacturers Make and Type, as this replaces the existing D0149/D0150 Market Messages it could lead to the information being lost. This will mean Energy Suppliers and MOAs will not know the make and type of meter installed at a particular Site.

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.

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.

02/06/2026 - the REC Change Panel voted to reject the implementation of this Change Proposal, in line with the Code Manager recommendation. The appeal window closed on 17 June 2026.
Summary
MHHS removes certain Data Items (e.g. Profile Class, Measurement Class, Standard Settlement Configuration, Time Pattern Regime etc.) that are important to wider processes and products offered to consumers. This proposal is seeking a mechanism for electricity Market Participants to look up the previous entries for these legacy Data Items held before MHHS Migration begins.

Clarification and Amendments to Annulment Definition in Schedule 23 – Alignment with SLC Obligations

Change Category
Priority
Urgent
No
Latest Update
This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
The current wording of the Annulment definition in REC Schedule 23 – Registration Services does not sufficiently align with the obligations set out in Ofgem’s Electricity Supply Standard Licence Conditions (SLC) 14.2(d),14.4(c) and 14.10. This misalignment has led to inconsistent interpretations of the usage of the Annulment process across the industry compared to the intention of the REC change and the licence obligation. This Issue is seeking further amendments to REC Schedule 23 - Registration Services and clearer guidance. This clarification is essential to prevent retention-based misuse, ensure regulatory compliance, and uphold Consumer trust in the Switching process.

Latest Update
08/04/2026 - The Closure Report was presented to the REC Metering Expert Panel at their meeting on 08 April 2026. The Issue has now been classed as resolved.
Summary
The issue identified is that current arrangements require or assume that legacy Meter Asset Providers (MAPs) take back old, non Smart Meters once they are removed from Consumers’ Premises, even though many of these meters are obsolete, cannot be reused, and ultimately require disposal. This has resulted in large volumes of legacy meters being transported across the country between storage providers and legacy MAPs, creating unnecessary cost, administrative burden, and environmental impact. Storage providers are issuing extensive lists of Meter Serial Numbers (MSN) to try to establish meter ownership, and legacy MAPs must manually verify these details. This process has been made more difficult by historical changes in company names and ownership structures. Once ownership is confirmed, the meters are frequently transported to the legacy MAP only for them to arrange disposal, which provides no net value and simply adds further transportation and handling costs.

Problem Statement
The process for handling removed legacy non Smart Meters is inefficient and environmentally costly, with unclear ownership, unnecessary transport, and no established recycling route. A consistent, sustainable disposal solution is needed to reduce waste, simplify operations, and clarify the management of any scrap value.

Latest Update
06/11/2025 - Following discussions at the Change Issues Group on 06 November, a REC guidance will be developed to support the resolution of this Issue after which it will be classed as resolved.
Summary
It has been identified by the MHHS Data Cleanse Working Group (DCWG) that around 9,000 existing Metering Point Relationships include Metering Points that would migrate into different Market-wide Half Hourly Settlement (MHHS) Market Segments. The majority of these are where one Metering Point has a Traditional meter installed (Smart Segment) and a Related Metering Point has an Advanced meter (Advanced Segment). This situation is currently valid but in MHHS would cause two problems. - SMRS would not be able to align the agent appointments, leaving secondary MPANs without agents and MHHS Migrations unable to fully complete.

Problem Statement
Without considering this Issue, there will be a risk to the MHHS migration. Indeed, a Metering Point installed which does not match its Related Metering Point (for example a Relationship between a Traditional meter with an Advanced Meter) will not be able to fully migrate to MHHS arrangements.
