Summary
This Issue has been raised to develop the dedicated Non-Domestic Change of Occupier SDEP screens that were not possible as part of R0155 – Change of Occupier: Evidentiary Standards and Timescales. Should this Issue progress with a developed solution, the new dedicated Non-Domestic Change of Occupier screens would replace the temporary work around provided as a temporary workaround in the R0155 solution.

Solution Development
Proposed solution summary
- The solution will be developed through the Change Issues Group. Attendees will be invited to discuss and determine the requirements for the dedicated Non-Domestic Change of Occupier SDEP screens (a separate screen will be required for both Gas and Electricity). The solution will also require reporting for Performance Assurance and will include a plan for queries raised at cut over and data retention obligations. To help drive those discussions a starting point could be as follows: • Meter Point X Number (MPxN) • Multi MPxN flag – i.e. are there more than one • Date of CoO • Number of attachments • Accept evidence - Y / N – only available to the receiving supplier • Additional info – must be populated if N Auto populate: • Date of creation, date of response. • The Service Level Agreement (SLA) is 10 Working Days so it will need the RAG status based on that. Escalations screens – as per the standard REC escalations – including MPxN, date of creation and number of attachments. As part of any solution, the Code Manager will also update the non-mandatory Non-Domestic Change of Occupier Guidance Document to include further details on the newly dedicated SDEP screens, as well as further training material for Energy Suppliers.
Problem Statement
Due to the MHHS Code Freeze, newly dedicated Non-Domestic Change of Occupier SDEP screens could not be implemented as part of the R0155 solution and instead the use of re-purposed, existing screens was proposed as a temporary workaround. Energy Suppliers were clear in their responses to the R0155 impact assessment and consultation that using a temporary work around (with the temporary solution being the use of existing screens PT0056 and PT0067) would create additional workload and risk and that newly dedicated SDEP screens for Non-Domestic Change of Occupiers would still be required.

22/09/25 - This Change Proposal has been implemented as part of the MHHS M8 22 September 2025 REC Release.
Summary
The process for Reconciliation of Unallocatable Transactions is set out in Section 10 of Schedule 11. During the most recent reconciliation delivery (the gas process from July 2024) several areas of improvement were identified, critically a lack of clarity regarding historic Supplier Licences and how to include or exclude them from the calculations. The Code Manager believes that this lack of clarity and past precedent would lead to material impact on one or more Party.

22/09/25 - This Change Proposal has been implemented as part of the MHHS M8 22 September 2025 REC Release.
Summary
The Electricity Smart Meter Equipment (ESME) ID is a unique identifier that provides a designation for a Smart Meter. Electricity Retail Data Agent (ERDA) systems were updated as per the requirements in R0033 to not allow for multiple incidences of an individual ESME ID to be registered, and reject the update, even when a second incidence of an ESME ID would be legitimate, for example in the case of a re-use of Metering Asset or a crossed meter. This Issue seeks to resolve this feature of the ESME ID validation while maintain data accuracy.

Problem Statement
ERDA data validation on the ESME ID Data Item in the D0312(MM00256) Market Message is imperfect, and can result in invalid rejections. This occurs when more than one incidence of an ESME ID is passed through individual ERDA system, as it only allows for a single occurrence, even if historic ones have been end-dated. In situations where a Metering Asset has been re-used, thus re-using the ESME ID, a rejection will occur, in an example of an unintended functionality of the validation system.

Latest Update
This Change Proposal was implemented as part of the 7 November 2025 REC Release.
Summary
The Switch Meter Reading Problems processes do not appropriately describe the use of rejections. This inhibits Parties from operating the process as intended and may cause unnecessary delay to the production of an accurate and agreed Switching Meter Reading. Additionally, the Performance Assurance Reporting Catalogue (PARC) is missing key data items to allow Performance Assurance to more accurately assure Party performance against Risk Drivers 5.6 and 5.8. Rejection reasons do not appear to be being reviewed, nor are they understood to be end statuses for the process.

Problem Statement
Suppliers may interact with the Missing Switch Read process in a way that is operationally standard for them, but not reflected in the Code. This means that the D0300 or SAR may either be escalated unnecessarily (including Performance Assurance checks), or may not be responded to, whilst still resolving the overall issue.
