This Change Proposal has been implemented as part of the February 2026 REC Release.
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.

Latest Update
06/11/2025 - Following discussions at the Change Issues Group on 06 November, a REC guidance will be developed to support the resolution of this Issue after which it will be classed as resolved.
Summary
It has been identified by the MHHS Data Cleanse Working Group (DCWG) that around 9,000 existing Metering Point Relationships include Metering Points that would migrate into different Market-wide Half Hourly Settlement (MHHS) Market Segments. The majority of these are where one Metering Point has a Traditional meter installed (Smart Segment) and a Related Metering Point has an Advanced meter (Advanced Segment). This situation is currently valid but in MHHS would cause two problems. - SMRS would not be able to align the agent appointments, leaving secondary MPANs without agents and MHHS Migrations unable to fully complete.

Problem Statement
Without considering this Issue, there will be a risk to the MHHS migration. Indeed, a Metering Point installed which does not match its Related Metering Point (for example a Relationship between a Traditional meter with an Advanced Meter) will not be able to fully migrate to MHHS arrangements.

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.

23/06/2026 - The Code Manager has published an Interim Guidance Document for I0273.
Summary
In the MHHS design the Standard Settlement Configuration (SSC) is a non-mandatory data item for Smart and Advanced metering points, in addition the register level TPR information is not shared in the MTD flows for these meters (IF-006 for Smart and D0268 for Advanced). It was identified through BSC Issue I118 that there is a requirement for the SSC to be set for Domestic / Microbusiness Advanced Metering Points making use of the HH data opt out and there may be other areas where the SSC is required.

Latest Update
This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
RECCo regularly reports on the performance of REC Service Providers in relation to their activities under the REC. However, there is currently no formal agreement to permit the publication of CRS performance measures between the CRS Provider and RECCo. Due to the multi-Party agreement, the REC does not specifically address the publication of this performance data. Instead, RECCo are operating under an informal understanding with the CRS Provider, which means there is a possibility that publication may be delayed or not agreed to in a given month. RECCo is dependent on the CRS Provider’s approval for each publication, which can cause delays. This approval could also be withheld at any point.

Problem Statement
Unlike REC Service Providers, there is currently no formal agreement in place between the CRS Provider and RECCo to publish details about the CRS Provider’s performance. RECCo is therefore dependent on the CRS Provider’s approval for each publication. Not only could there be delays in RECCo’s reporting, but the approval could also be withheld at any point, preventing RECCo’s reporting.

Summary
REC Schedules 1, 14, and 15 all note that in order to Qualify as a Safe Isolation Provider (SIP), the Party needs to be a Qualified Meter Operator Agent (MOA). It has since been determined that Qualified Electricity Metering Operatives (EMOs) should also be able to Qualify as SIPs.

Problem Statement
Requiring SIPs to be fully Qualified MOAs may be hindering smaller Parties who wish to be SIPs from Qualifying under the REC. This in turn may be reducing the number of Qualified SIPs in the market for Consumers to choose from or causing Consumers inadvertently to contract with people who are not Qualified SIPs to carry out SIP Works.
