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.

Summary
The creation of Import Metering Points for new Premises sits with the Distribution Network Operator (DNO), while the Export Metering Points generally sit with the Electricity Supplier. When the DNO approves the G98 Engineering Recommendation Installation Document (Form B) or G99 Engineering Recommendation Installation Document (Form A3-1 or A3-2) under the Distribution Code, they could create Export Metering Points at this time (with the logical Disconnection process being available for any Export Metering Points that are then not required).

Problem Statement
The information required by the DNO to create an Export Metering Point sits with the Consumer rather than the Electricity Supplier, and leads to the Electricity Supplier acting as an unnecessary third party in the process. This is leading to unnecessary time being added to the process, negatively impacting Consumers and the journey to Net Zero. This is particularly apparent for large new housing developments, which may have several tens of thousands of Export Metering Points to create with the same DNO and require the use of the Bulk Request process. This process is cumbersome and has no two DNOs operating the process in the same way.

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.

Problem Statement
Where DNOs have enhanced reporting tools for Category A or Category B situations, it is not mandatory for Parties to submit reports using this method. This may lead to a detrimental Consumer experience, as it is limited what information can be provided over the telephone or via Market Message (e.g. it is not possible to provide photographs of the situation).

09/04/2026 Following a review of responses to the joint information request on REC Issues I0273 - Sharing of SSC and TPR Information for MHHS Smart and Advanced Meters and I0303 - Potential Consumer detriment for Smart Economy 7, the Code Manager has determined that the scope of REC Issue I0303 can be considered as part of the solution development for REC Issue I0273. I0303 has now been classed as resolved and will not be progressed further as a separate Issue. For further engagement with this issue, please refer to I0273 directly.
Summary
There is a potential for Consumer detriment under the Market-wide Half Hourly Settlement arrangements where a customer unknowingly selects a tariff (i.e. single rate) where they have an Economy 7 type configuration on a Smart meter for water/storage heating.

Problem Statement
There is a potential for Consumer detriment under the Market-wide Half Hourly Settlement arrangements where a customer unknowingly selects a tariff (i.e. single rate) where they have an Economy 7 type configuration on a Smart meter for water/storage heating. A solution is required that enables a Supplier to identify a Smart E7 Consumer during the Switch process to ensure they can offer the correct tariff and prevent consumer detriment.

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.
