Summary
Raising on behalf of the Gas Networks, who currently struggle to find who to email queries to within suppliers organisation. Suppliers and Electricity DNO's moved to SDES to ensure all communications were in a secure portal, with SLA's and for GDPR reasons, but Gas Networks do not have access to this portal, and not considered during the implementation of the system. They also obtain photo's when out on site to help resolve queries and would like somewhere to upload them to send to suppliers.

Problem Statement
Energy Suppliers and Distribution Network Operators (DNOs) moved to SDES to ensure all communications were in a secure portal, with SLAs and for GDPR reasons. Gas Transporters do not have access to this portal, and were not considered during the implementation of the system. As such, communications are not being sent as securely as possible.

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.

Summary
Ofgem have been in with discussion with Energy Suppliers this year, requesting them to voluntarily change how they use the consent option within the Priority Services Register (PSR) flow. This Change Proposal (CP) has been raised to make sure the Market Message mirrors the process agreed between Ofgem and Energy Suppliers by re-naming the Priority Services Register (PSR) Data Item DI51497 (J2208) as “Lawful basis for sharing” and to amend the relevant clauses in REC Schedule 13 if needed.

21/05/2024 - This change proposal has been withdrawn and the adoption window is closed. There is no longer the requirement for the requester to have Enquiry Services Data.
Summary
There are organisations that are named in Schedule 12 - Data Access that are not recorded in the gas and/or electricity Data Access Matrix (DAM). This means it is not possible for the Code Manager to provision them access. All organisations listed in Schedule 12 to access data in the REC should have an entry in the Data Access Matrices. This Change Proposal has been raised to review the Schedule and DAMs and take forward the necessary changes.

Summary
This change looks to remove business rule 1177, from the Central Switching Service (CSS) Message Business Data Validation Rules, which mandates that all Suppliers have a ‘One Fail All Fail’ (OFAF) reference included in their Switching Operational Data record in CSS. This was not the intended design. CSS system functionality will be updated as part of an operational change, as agreed at Switching go-live. This change is required to align the Data Specification with the operation of the system.

Latest Update
08/11/2024 - This Change Proposal has been implemented as part of the November 2024 REC Release.
Summary
Annulments are defined in the interpretations schedule as: Annulled means that a Registration has been annulled by the Losing Supplier pursuant to an Annulment Request. “Annulment” and similar expressions shall be interpreted accordingly. Annulment Request means the Registration Service Request from the Losing Supplier to terminate the progress of a Registration in accordance with Paragraph 10 of the Registration Services Schedule. The Registration Services Schedule does not define an annulment but sets out in para 10: A Losing Supplier must only submit an Annulment Request in respect of a Registration where the Losing Supplier is permitted to do so in accordance with its Energy Supply Licence. Unfortunately the Energy Supply Licence does not refer to annulments, making this term not clearly defined. REC Performance Assurance (RPA) have identified Parties using annulments when they should use other processes. The lack of a clear definition of what an annulment is could be a contributing factor to this.
