21/10/2025 - the REC Change Panel approved the withdrawal of the proposal plan for R0162 and that this Change would be placed on hold while I0285 progresses.
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 Secure Data Exchange Portal (SDEP) is a mailbox that enables the transfer of sensitive customer related data in a way that ensures data is safe and secure. Suppliers are obliged to send and receive queries and escalations via the SDEP. Unfortunately, the SDEP has issues in bulk resolving processes which could be solved by the removal of the prohibition of the use of robotics. For example, there is no function to be able to retrieve cases specific to each team, work these and then automatically issue a response. Currently, to get the same kind of functionality, an agent or team lead would need to manually process. In another scenario, under REC schedule 30, as part of each of the processes, we are obliged to issue an escalation where there has been no response within set timeframes. Prior to SDEP implementation, we would be able to issue email escalations automatically where there was an absence of a response flow. With the SDEP this process is now manual: an agent will need to sign in to ECOES, navigate to the appropriate module, and input the data.

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.

04/06/24 - This change has been withdrawn by the proposer and is being incorporated as part of R0178 - Improvements to CSS Business Process Logic. 03/05/2024 - An investigation was held into the requirements of this change and into other issues identified with the CSS Business Process and Logic. Landmark have provided data relating to the number of incidents for three different scenarios which had been identified. A discussion as held between the Code Manager, DCC and Landmark, and agreed that they will look to combine all identified issues into a new REC Change Proposal.
Summary
This change looks to resolve the issue for Registration Events where the incumbent Supplier deactivates prior to a Switch becoming effective. In some instances, the incumbent Supplier is withdrawing prior to the ‘Supply Effective from Date’ which causes the accepted Switch to fail at Gate Closure (17:00hrs) . An effective solution is to allow the consumer to Switch with the original effective date. There are a number of solution options to enable this to happen.

Problem Statement
This is a Housekeeping Change Proposal subject to the Housekeeping Change Proposal process, rather than the standard change process. The nature of the change is that it makes non-material changes to the REC Products to correct typographical and consistency errors. It also provides an opportunity to introduce necessary clarifications.

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.

Proposed solution summary
- As a Non-Domestic Consumer, I want to work with TPIs who are demonstrating best practice standards within the market.
- As a Non-Domestic Energy Supplier, I want clear obligations around my use of TPIs so I can demonstrate best practice standards within the market and ensure my audit obligations are met.
- As RECCo, I want to provide an assurance and accreditation scheme to register TPIs to remove the burden of Suppliers having to individually audit TPIs.
- As a Third Party Intermediary, I want clear obligations so I can become accredited and assure that Suppliers and Non-Domestic Consumers are receiving best practice standards within the market.

Problem Statement
Non-Domestic Consumers have more limited protections than Domestic and Microbusiness Consumers in the energy market, and so may not always experience best practice from all parties they interact with. The aim is to expand these protections while limiting the audit burdens on Suppliers and TPIs.
