Summary
The REC Metering Operations Schedule has limited distinction between the activities for import and export metering. These provisions were not specifically developed to support a market with high volumes of small-scale microgeneration with shared metering assets for import and export.

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.

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.

Latest Update
07/07/2026 - The Change Report (Update to Plan) has been approved by the REC Change Panel. This Update to Plan reset the Priority Category and urgency status of R0294, following the deferred implementation of the lead BSC CP 1607. R0294 continues to be on hold until further solution development is undertaken as part of CP 1607. The Code Manager will continue to work with Elexon and Service Providers for future progression of any changes to implement the IF-051.
Summary
The IF-051 provides a refresh of data from Supplier Meter Registration Service (SMRS) to the Electricity Enquiry Service (EES) (REC) and Market Data Service (BSC). Currently the REC does not hold any detail regarding the DIP Market Messages that the EES is required to receive and process. Due to the nature of the IF-051, the EES Provider obligations need to be clear to ensure the interface can be received and processed appropriately.

Problem Statement
BSC CP 1607 will implement a new DIP Market Message, the IF-051 ‘Data Refresh’ on 26 March 2026. EES will be a recipient of that change. If EES is not able to receive and process instances of the IF-051, data in EES will be misaligned with other industry systems (SMRS, DIP and MDS) meaning that it will not maintain its role as the accurate reference point for industry participants. This could lead to potential disruption of industry processes.

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.

23/06/2026 - The Code Manager has published an Interim Guidance Document for I0273.
Summary
In the MHHS design the Standard Settlement Configuration (SSC) is a non-mandatory data item for Smart and Advanced metering points, in addition the register level TPR information is not shared in the MTD flows for these meters (IF-006 for Smart and D0268 for Advanced). It was identified through BSC Issue I118 that there is a requirement for the SSC to be set for Domestic / Microbusiness Advanced Metering Points making use of the HH data opt out and there may be other areas where the SSC is required.
