Summary
It has been suggested that CHECK meters should not be sent within industry messages so the presence of this value within the valid set may not be required. This Issue has been raised to explore whether this assumption is correct, look at the existing/historic use cases industry have used the CHECK option for, if they are no longer valid and if so why not.

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.

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.

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
A Data Integration Platform (DIP) Data Item, DI-091 ‘Number of Displayed Register Digits’ that was implemented as part of MHHS has been incorrectly linked to the existing J0478 ‘Number of Register Digits’ in the Energy Market Data Specification, instead of the existing J2313 ‘Number of Displayed Register Digits’.

Proposed solution summary
- The proposed solution is to conduct a correction exercise to unlink the DIP Data Item DI-091 ‘Number of Displayed Register Digits’ from the Data Item J0478 and it should then instead be linked to the Data Item J2313.

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.

Implementation of IF-051 Data Refresh in EES for BSC CP1607

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.
