Summary
When Registered Gas Suppliers and Registered Shippers access the Gas Enquiry Service (GES) they currently have access to their own unique set of Data Items. This Change would give Registered Gas Suppliers access to some additional Data Items which form part of the Registered Gas Shipper Data Items, to enable them to solve Consumer facing switching and billing issues.

Proposed solution summary
- As a Consumer, I want my Supplier to be able to access essential information about my energy account, so that billing issues and switching problems can be addressed easily.
- As a Registered Gas Supplier, I want to be able to readily access appropriate information relating to my RMP portfolio, so that I can resolve consumer facing billing issues more easily. As the GES Provider, I want my users to be able to access information that helps them fulfil their objectives (in line with REC Data Access principles), so that the service is used as efficiently as possible.

Problem Statement
When Registered Gas Suppliers need to resolve queries relating to meter reading history, they may need to access information that is currently only available to the Registered Shipper in GES. As a result, Registered Gas Suppliers may be unable to resolve these consumer facing issues on their own, as they do not have direct access to the required Registered Shipper only information.

Latest Update
19.09.2023 - approved for implementation in February 2024 Release
Summary
In order for central systems testing (including maintenance and emergency testing) to be undertaken by the Switching Operator, certificates from the SDSPs and CSS User communities are required to interact with CSS in the testing environments. The Switching Operator was able to issue certs to the simulator provider during the Switching Programme, but the replacement process via Service Now no longer allows this – instead placing onerous activity on Parties to collaborate with the Switching Operator to give them the ability to request certificates on their behalf. This change has been raised to ensure that test certificates are held at all times for enough parties to enable changes to be tested with enough simulation to replicate live operational scenarios. The solution proposed is that the Switching Operator can nominate Technical Contacts (TC) for all CSS Users, in order that certificates can be requested for simulators in the test environments. CSS Users would continue to be able to nominate / remove their own TCs as now (and be able to remove the Switching Operator-nominated Technical Contact), and would see all TCs listed on the Switching Portal.

Problem Statement
Due to certificate expiry, there are not currently sufficient test security certificates for connecting to CSS test environments and emulating CSS Users (simulators). The current process for CSS Users to request certificates is inefficient and is reliant on the CSS Users obtaining new certificates in a timely manner. Without sufficient test certificates, the Switching Operator may not be able to fully test changes to the CSS system.

Summary
REC Parties have started to prepare for the release and implementation of R0032, during this preparation the REC Code Manager has received questions about the approved solution, specifically regarding the version of the D0312 (MM00256) Market Message (version 002 has been maintained through R0032) and the number of register digits that should be provided for specific meter types. The Code Manager has reviewed these questions and determined changes are required to the approved solution. Therefore, this Change Proposal has been raised to progress changes to the approved solution.

Following a review, the Code Manager confirmed that changes are required to the approved solution for R0032, which will ensure Parties have sufficient clarity to implement the required changes to their own systems and processes.

Problem Statement
Where a Consumer initiates a Switch through a Supplier, PCW or TPI that utilises the EES API address searches can fail as the API only undertakes “fuzzy” matching. Address Search errors will then need to go through an exception handling process creating an inefficiency and producing a loss of confidence in the Switching process.

Problem Statement
The implementation of Change Proposal R0044, will result in the Central Switching Service (CSS) providing an asynchronous response to the Electricity Retail Data Service (ERDS) upon a successful, or unsuccessful Smart Meter Data Retriever (SMDR) appointment within the SMDSP. This will significantly increase the volume of CSS messages, as there is currently no mechanism for the CSS to recognise when a response is required. The increased volume could have a significant impact on central system performance.

An inability by the Central Switching Service (CSS) to re-generate Market Messages that were not sent as intended can result in issues with the Switching process, both for REC Parties, and Consumers. This Change seeks to create a message regeneration functionality that would mitigate this Consumer detriment.

Problem Statement
Failures by the CSS to generate Market Messages can result in a breakdown of the Switching process. As the CSS cannot re-generate Market Messages that should have been sent but were not, this results in message asynchronisation, and breakdown of CSS functions and processes, resulting in substantial impacts for those involved – Difficulties for the REC Parties using the CSS, and difficulties for Consumers, where the Switch process is impacted.

Latest Update
10/04/2026 - Change has been taken of hold. This change will be triggered for a reassessment for Code Manager Impact on 14/04/2026.
Summary
When Meter Point Administration Numbers (MPANs) are erroneously disconnected, they cannot be reinstated. As a result, Consumers suffer billing issues and Registered Suppliers cannot settle against the disconnected MPAN. This change seeks to introduce a mechanism to restore erroneously disconnected MPANs.

Proposed solution summary
- As a Consumer, I do not want the erroneous disconnection of my MPAN to affect the continuity of my supply contract and billing arrangements.
- As a DNO, I want to be able to reverse erroneous disconnections with no lasting effect so that I don’t need to create a new MPAN to resolve the issue, thereby avoiding DUoS payment collection issues. 2 - As a Supplier, I want to be able to reverse erroneous disconnections with no lasting effect so that I can correctly bill my consumers. 3 - As the CSS, I want users to be able to effectively resolve discrepancies, so that industry data for their portfolio is accurate. 4 - As MPRS, I want users to be able to effectively resolve discrepancies, so that industry data for their portfolio is accurate.
Problem Statement
When MPANs are incorrectly identified and targeted for disconnection, the RMP will be erroneously terminated following receipt of Termination Market Messages by the CSS. This process is irreversible once triggered, meaning that there is no mechanism to restore the MPAN as it was previously. This results in a poor Consumer experience, and settlement misbalancing for Registered Suppliers. Currently, there is no mechanism to mitigate the negative impact on Registered Suppliers/DNO and Consumers.
