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.

Proposed solution summary
- As a Consumer, I want to have continual Meter Equipment Manager coverage, so that I am confident that work on my Metering Asset can be conducted even during a Switch.
- As a MEM, I want my obligations relating to appointment and de-appointment to be considered and practicable, so that my operational processes are not unduly onerous. 2 - As a Gas Supplier, I want to be able to reliably and predictably appoint and de-appoint MEMs during a Switch, so that I am confident that my Consumers are not left without a MEM at any stage. 3 - As the Code Manager, I want REC processes to operate within SLAs that are reflective of both the realistic operational capacities of REC Parties, and also of the needs of the broader market, so that the end Consumer has the best possible Switching experience.
Problem Statement
Current ONAGE SLAs may no longer be proportionate to the length of the Switching process as a result of the Faster Switching programme. Lengthy ONAGE SLAs relative to the timescale of the switching process may result in Consumers being left without a MEM during the switch process. The proposer has asked the Code Manager to conduct a review of the ONAGE SLAs to explore whether these SLAs are still appropriate, and therefore ensure that Consumers are subject to any detriment.

08/11/2024 - This Change Proposal has been implemented as part of the November 2024 REC Release.
Summary
This change has been raised to address an issue with the 'Switch with a Concurrent Change of MEM process.'. MEMs are obliged to issue ONJOBs to the CDSP as part of a meter exchange. However, this would not be issued if the MEM has received a de-Appointment flow as part of the Switch. This change proposes to obligate MEMs to issue ONJOBs for any completed meter exchanges, even after receiving a de-Appointment flow. This will ensure accurate Meter Technical Details are available to the gaining Supplier and MEM.

- As a Consumer, where I have entered a bi-lateral NExA with the relevant Transporter, I want my Shipper and Transporter to have access to all the data they need when capacity referrals to the Gas Transporters are required.
- As a Gas Transporter, I want the details of the NExA to be held in GES, to increase visibility of the existence of the NExA and to provide details of the offtake parameters.
- As a Gas Shipper, I need to understand both that a NExA exists, and that I have visibility of the offtake parameters relative to the site, so that I can ensure that I take the necessary actions to ensure the Consumer has the appropriate booked Supply Point Capacity.

- As a Consumer, I want a Metering Equipment Manager to be able to access and validate my site details, ahead of their arrival on site for planned or emergency metering work, so that I do not experience any delays in work being completed and can have continuity of supply.
- As a MEM, I want access to sufficient data for sites where I am not the Appointed MEM, to enable me to complete pre-metering works validations of the site details, so I can undertake these works correctly and safely.
- As a MEM, I want access to data for sites where I am not the Appointed MEM, so I can confirm de-appointments and answer invoice validation queries.

GES Data Access Matrix for R0074
Archive
Off
Problem Statement
At go-live for REC v3.0 the ‘Community View’ access to data in the GES, previously available via the DES under the UNC, was inadvertently removed. MEMs used this data in a number of processes, including validation of site details prior to metering works – particularly for emergency work, and the resolution of invoice queries from Suppliers. Without access to this Enquiry Service Data, MEMs are unable to complete activities that are central to their operations, including checking site details prior to attending emergency metering works. This has the potential to have a direct negative impact on the experience of metering works for Consumers, and in in some cases, continuity of supply and safety could be at risk.

The Frequency of reports set out in the Gas Enquiry Service Definition document does not currently reflect the expected frequency for the ‘Supplier Registration report (MEM)’, ‘Portfolio Data (MEM)’ and ‘Portfolio Data (MAP)’ reports. The Gas Enquiry Service Definition needs to be amended to ensure that Meter Equipment Managers (MEMs) and Meter Asset Providers (MAPs) receive reports in the correct timeframe.
