Summary
Currently, the location (A0059) data item within the ONAGE APPT file from Suppliers to MAMs is Optional, this allows a Supplier to leave this field blank. Currently SGNCS system functionality is designed to reject the file if this field is blank. This is due to SGNCS requiring to hold the location of the meter installation in order to allow us to deliver on our safety obligations as a MAM in maintaining of an asset.

This Change Proposal has been implemented as part of the June 2026 REC Release.
Summary
R0277 – Data Latency SLA alignment for Gas Enquiry Service amended two performance levels within the Gas Enquiry Service (GES) Service Definition. However, these changes only addressed ambiguity on when the performance level applied from and to and increased the number of hours in which data will be available to Authorised Persons within the Supply Point Switching API. This change will seek to support the changes made under R0277 whilst also providing a suitable percentage SLA target for the Gas Enquiry Service Provider to meet these measures.

Summary
The current performance level for the processing of Data from CDSP is no longer fit for purpose and does not reflect the operational capability of the service. The performance level was originally conceived as part of the CSS programme in 2022 and operational reality has shown it is not required by industry. A revision of the performance level will align service performance metrics with system performance and deliver economic benefit.

Problem Statement
The current performance levels for the processing of data from CDSP is no longer fit for purpose and does not align with system or service performance. The CSDP is also not meeting these performance levels on a monthly basis. While there are no known issues on data latency raised by users, this change to clarify performance levels is needed for the GES reinstated contract and to ensure ongoing service delivery.

21/07/2026 - Change Report (Proposal Re-Plan) approved at Change Panel
Summary
As per Section 13.4.18 of CoMCoP, retrieving gas pressure and capacity information from Transporters via the GT1 process can be time consuming for Energy Suppliers/MAMs and/or Consumers. The process of retrieving this information is inconsistent and service timescales are varied between transporters. Gas pressure and capacity information should be readily available through the Gas Enquiry Service to enable timely processing of site work and requests to enable MAM’s and Suppliers to appropriately service their customers.

Problem Statement
For some Energy Suppliers, MAMs and consumers, retrieving pressure and capacity information via the GT1 process can be time consuming. This is due to elements like response timescales and methods (batch responses vs individual responses) being varied among GTs. This ultimately has a negative impact on customers waiting on site work, such as a new connection, for example.

Summary
Gas Transporters (GTs) only have a single obligation in the Smart Energy Code (SEC). This obligation relates to the provision of Registration Data to the DCC. This issue is exploring whether these obligations may be transferred to the REC.

Problem Statement
Gas Transporters have very few obligations under the Smart Energy Code; those that they do have relate to provision of data owned by the REC. If these obligations were to be moved from the SEC to the REC, then the regulatory burden on GTs may be reduced as they would be able to completely secede from the SEC.

Latest Update
28/07/2026 - update to plan published for decision at the Change Panel on 4 August 2026.
Summary
As TPIs we are employed by our customers to check that the charges are being applied correctly. One of the big issues year after year is when the SOQ changes for a supply prior to the next supply contract renewal. As you are hopefully aware, the standing charges for Gas supplies are primarily built up around the Transportation charges. And one of the main component parts in the calculation of the standing charge is the SOQ. When we are asked to :- a) Validate the standing charge on any new offer, we are reliant on the supplier simply getting the SOQ correct. We need to see the SOQ so that we can work out what the standing charge should be. - then we challenge the supplier before they get the charges wrong. b) Our customers also want us to forecast the rates/costs for the coming year. This is impossible without access to the SOQ.

Problem Statement
The annual portfolio reconciliation exercise conducted by the CDSP on MAM-held Data Items is neither frequent enough nor is it expeditious enough, according to the Proposer. MAMs are being asked to reconcile Data Items several months after they were initially provided, which may impact the efficacy of the exercise if these Data Items have changes since they were initially submitted.

Problem Statement
The example responses detailed in section 4.2 are broken down as ‘mprn’ with three demoed data items; ‘mprn’, ‘installation name’, and ‘network name.’ this is however not reflective of the correct responses that would actually be returned on an API call. The actual structure is ‘supplier’ with the demoted data items actually being ‘amr_indicator’, ‘amr-sp’, and ‘csep_id.’ Fundamentally, this would mean that users are consuming incorrect information when looking to this document for guidance. This could potentially be causing negative impacts when the document is relied upon, especially for newer users seeking guidance.

27/02/2025 - Change is now not being merged into any other changes and will proceed as a standalone change. A potential solution has been identified, but will be discussed for potential cross code impacts
Summary
Currently within Schedule 23 a Registration can only be undertaken on RMPs with an Operational or Dormant RMP Status, and not Terminated. Terminated is a status that the RMP is set to when the Meter Point Status is no longer operational or the site is isolated. It is right that these sites are not able to be Registered as there is a risk that Suppliers could inadvertently Register such Meter Points. We do have instances where such sites are stranded in defunct Supplier portfolios - and the Supplier no longer has the capability to take the relevant action to Deactivate the Registrations. This may because the operational staff have left and the business is in administration.
