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.

Obligations are being introduced into the REC to require Suppliers to make Tariff Pricing Data available to Tariff Interoperability Users (TI Users) using a new Tariff Interoperability Application Programming Interface (TI API). This proposal will provide Code Manager with data to assure supplier performance against obligations in a new REC Schedule: Tariff Interoperability Arrangements.

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.

This Change Proposal has been implemented as part of the June 2026 REC Release.
Summary
During the quality checks of REC Schedules for MHHS, several capitalised terms throughout schedules were identified with no entry in Schedule 1. It has also been identified that there are definitions that link to Schedules (such as 2, 20 and 21) which are no longer live REC Schedules. The Code Manager has reviewed these and determined some changes are required to Schedule 1.

Latest Update
29/04/2026 - This Issue has been withdrawn by the Proposer, as there was not a strong preference amongst MAPs of which temporary solution option (if any) should be progressed. Many MAPs already have workarounds in place, and a permanent solution is expected to be progressed in the future through a joint REC / BSC change. The adoption window has closed.
Summary
As part of Market Wide Half Hourly Settlement (MHHS) design, the requirement to provide Data Item Effective from Settlement Date {REGI} (J0049 / DI50025) in the Notification of Meter Operator, Supplier and Metering Assets installed / removed by the MOP to the MAP Market Message (D0303 / MM00240) has been changed from mandatory to optional. This means Meter Asset Providers (MAP) may not receive it.

Latest Update
27/02/2025 - Change is now not being merged into any other changes and will proceed as a standalone change. A potential solution has been identified, but will be discussed for potential cross code impacts
Summary
Currently within Schedule 23 a Registration can only be undertaken on RMPs with an Operational or Dormant RMP Status, and not Terminated. Terminated is a status that the RMP is set to when the Meter Point Status is no longer operational or the site is isolated. It is right that these sites are not able to be Registered as there is a risk that Suppliers could inadvertently Register such Meter Points. We do have instances where such sites are stranded in defunct Supplier portfolios - and the Supplier no longer has the capability to take the relevant action to Deactivate the Registrations. This may because the operational staff have left and the business is in administration.

16/05/2025 - the Authority have published their decision to reject R0137 and R0137A.
Summary
This change seeks to expand the obligation for Energy Suppliers to only work with TPIs who are adhering to principles as set out in the REC TPI Code of Practice to all Non-Domestic Consumers. It also looks to reduce the burden on Energy Suppliers having to perform their own audits by introducing a REC Services Accreditation Scheme and allowing companies to qualify as an Industry-Recognised Accreditation Body.
