Summary
Under the legacy/pre-MHHS arrangements the market is segmented by Measurement Class (MC) for settlement purposes which is not sensitive to the Meter type that is installed or is to be installed, meaning that the replacement of Traditional meters to either smart or Advanced metering equipment can be arranged without the need for the Change of Measurement Class (CoMC) process to be conducted concurrent with the meter exchange (MEX). Under MHHS, when a WC connection goes through a MEX from Traditional to Advanced, or from Advanced to Smart in the MHHS arrangements a new complexity is placed on suppliers because the CoSeg process must be tightly co-ordinated to a specified planned MEX date and processed through the MPRS within 3 Working Days of that date.

Summary
BSC CP1633 “Capture Modem Module Details Under BSCP601” makes amendments to BSCP601 Metering Protocol Approval and Compliance Testing. One of the amendments places obligations on MOAs where they are introducing and amending Communications Equipment. Equivalent and potentially expanded obligations need to be placed within REC Schedule 14 Metering Operations to support this.

Consultation issued June 29th
Summary
This proposal introduces a formalised “Sweet Treat Reward System” within the REC governance framework, whereby participants are recognised with confectionery based incentives for timely delivery, high quality submissions, and proactive engagement in the change process. The change aims to improve stakeholder participation, reduce consultation fatigue, and enhance overall delivery performance by introducing a light-touch behavioural incentive aligned to existing governance activities.

Solution Development
Proposed solution summary
The proposed solution is to introduce a new REC provision establishing a “Sweet Treat Reward System” (STRS), creating a light-touch, non-financial incentive mechanism linked to existing change process activities. This would require updates to REC governance documentation (e.g. Change Management schedule and supporting guidance) to define eligibility criteria, reward thresholds, and roles, with the Code Manager responsible for administering and maintaining the scheme and recording outcomes within the REC Portal.
End-to-end, the solution would operate by linking stakeholder behaviours (e.g. timely consultation responses, active participation in CIG discussions, and high-quality submissions) to predefined reward triggers. The REC Portal would be enhanced to capture participation metrics, calculate eligibility, and notify participants of earned rewards via automated communications (e.g. portal notifications or email), with a monthly or milestone-based cadence. Data flows would include submission timestamps, attendance records, and qualitative assessment inputs from the Code Manager or Change Leads, which would be consolidated into a “Reward Eligibility Log” maintained within REC systems.
Implementation would be led by the Code Manager, supported by the DSP for system changes and reporting capability, and overseen by REC governance bodies to ensure alignment with existing obligations and neutrality principles. The solution would not alter core decision-making processes but would overlay an engagement-focused mechanism, with clear accountability for administration, auditability of outcomes, and periodic review to ensure continued effectiveness and proportionality.
Problem Statement
The REC change process currently relies on formal obligations and voluntary participation to secure stakeholder engagement; however, this approach does not consistently drive timely, high-quality input during key stages such as consultations and working groups. As a result, participation can be delayed, inconsistent, or limited in substance, reducing the effectiveness of impact assessments and slowing overall change delivery.
In the absence of any positive reinforcement mechanisms, the process places full reliance on compliance rather than motivation, which may not fully reflect the human factors influencing engagement. This creates a persistent gap between the intended collaborative nature of the REC and the reality of stakeholder behaviour, ultimately affecting the pace and quality of change outcomes delivered to the market.

19/08/2026 - the Change Report (Proposal Plan) was approved by Change Panel. The Change Team and Performance Assurance team are working together to determine if there are performance assurance requirements for this change.
Summary
An incident where Network Parties did not submit Regulatory Alliances on time to the Central Switching Service (CSS) Provider, or did submit the Regulatory Alliances but did not action rejections from the CSS Provider in a timely manner, led to over 200 Consumers being delayed in Switching to their chosen Energy Supplier. This Change Proposal has been raised to review this process.

14/08/2026 - the consultation has opened, responses must be received by 23:59 07 September 2026.
Summary
Schedule 14 - Metering Operations currently holds obligations for a Meter Operator Agent (MOA) to send a D0383 ‘Notification of Commissioning Information’ to Electricity Suppliers, Distribution Network Operators (DNOs), Data Services and Data Collectors in certain process steps. The D0383 was not shared with these Parties in legacy arrangements, and there is no requirement for it to be sent to facilitate the MHHS arrangements. There are similar requirements to send the D0384 ‘Notification of Commissioning Status’ to these Parties, when it is only required by the Electricity Supplier. These requirements were introduced by the MHHS Design in error and need to be removed.

Problem Statement
Schedule 14 - Metering Operations puts obligations on MOAs which are both not required and impossible to fulfil (as the Scenario Variants to send the D0383 from the MOA to the Electricity Supplier, DNO, Data Service and Data Collector do not exist). There are similar problems for the D0384, which is only required to be sent from the MOA to the Electricity Supplier.

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.

Problem Statement
A linkage error has been identified as part of BSC CP1622 and REC Change Proposal R0300 where the DIP Data Item DI-091 has been incorrectly linked to the existing J0478 ‘Number of Register Digits’ in the EMDS at MHHS Go-Live, instead of the existing J2313 ‘Number of Displayed Register Digits’. As a result, contrary to the MHHS design and intended linkage, the EMDS incorrectly details the DI-091 in DIP interfaces, including the IF-005 and IF-006 (both REC-owned) and several other DIP Interfaces, even though the DIP reference appears correct (DI-091). It is important that EMDS is an accurate reflection of Market Messages and Data Items. Without correction this Issue may cause issues to future market entrants.
