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.

Summary
Gas Transporters (GTs) only have a single obligation in the Smart Energy Code (SEC). This obligation relates to the provision of Registration Data to the DCC. This issue is exploring whether these obligations may be transferred to the REC.

Problem Statement
Gas Transporters have very few obligations under the Smart Energy Code; those that they do have relate to provision of data owned by the REC. If these obligations were to be moved from the SEC to the REC, then the regulatory burden on GTs may be reduced as they would be able to completely secede from the SEC.

This Change Proposal was implemented as part of the 7 November 2025 REC Release.
Summary
The Public Switched Telephone Networks (PSTN) will be switched off in December 2025 by all telecom companies and will be replaced with an Internet Protocol (IP) digital network. Existing fax machines that are incompatible with new all IP digital networks will become obsolete and no longer capable of meeting Code Communications as prescribed in the REC. All communication methods referencing fax or facsimile will need to be removed and replaced with email (where this is not an existing option), unless an alternative form of communication is needed. Please note: The government have published preparatory guidance which includes migrating to IP-supported technology in advance of the planned decommissioning. UK transition from analogue to digital landlines - GOV.UK (www.gov.uk) Critical National Infrastructure (CNI) (“assets, facilities, systems, networks or processes and the essential workers that operate and facilitate them”) which is subdivided into 13 sectors including Energy, are advised to consider how they move to digital alternatives smoothly to avoid unnecessary interruption following the PSTN switch-off. Openreach's Energy Guidance Factsheet can be found in the CPs Accompanied Documents.

Proposed solution summary
- As a Consumer, I want a competitive Export market so I can get the best rates for the energy I generate. I want clear metering equipment ownership so I can be confident my meter is functional and safe. I want accurate billing from my Export Supplier.
- As an Export Supplier, I want to be able to appoint the MEM that ties in with my commercial strategy.
- As a MEM, I want clear guidance on the responsibilities I have for any metering equipment I am appointed to.
Problem Statement
Export Suppliers may become non-compliant with industry regulations if they are unable to appoint the same MEM as the Import Supplier, for example when the Consumer switches Import Supplier or when the Import Supplier changes the appointed MEM.

Problem Statement
The MHHS Target Operating Model requires that the appointment data of the Smart Meter Data Retriever (SMDR) is available to the Smart Meter Data Service Provider (SMDSP), so that the SMDSP can provide SMDRs with access to the Smart Meters at Metering Points they are registered to. Currently the new SMDR role and appointment data do not exist in, nor can they be made available from, CSS as this is a new industry operating model.
