Summary
It has been raised to the Code Manager by a Party that the Scenario Variant of Supply Fault Information Centre (SFIC) to Crowded Meter Room MEM (CMRM) is missing from the D0126 / MM00016 (Asset Condition Report Response / Clearance) Market Message. This should have been introduced as part of REC Change R0043 which introduced the role of the CMRM.

Problem Statement
CMRMs can send the D0135 / MM00023 Asset Condition Report Market Message to the SFIC, but the SFIC cannot send a response on the D0126 / MM00016 Asset Condition Report Response / Clearance Market Message to confirm the outcome of their investigation.

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.

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.

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.

This Change Proposal has been implemented as part of the June 2026 REC Release.
Summary
There is no requirement for energy suppliers planning fewer than 5000 Smart meter installations at domestic premises, within a calendar year, to survey Consumers for REC compliance purposes. Conversely, there is no minimum threshold in place for microbusiness installations, meaning that non-domestic suppliers are required to procure a suitably qualified, independent Smart Meter Installation Survey Organisation, at considerable cost, to survey what might be a very small number of customers.

Summary

06/05/2026 - The Change Report (Extension to Plan) was approved at Change Panel on 05 May 2026. Solution Requirements are under development.
Summary
Currently, it is uncertain how widely the existing Theft Assessment Calculators are being used by Parties for assessing energy losses due to theft, despite Schedules 7 & 8 mandating the usage. There is evidence to suggest inconsistent application across Parties, and whilst there has only been one derogation request, anecdotal feedback indicates that other Parties are also struggling to use the calculator.

Solution Development
Proposed solution summary
- It is expected that there will be a collaborative information gathering exercise to thoroughly assess the current Theft Calculator. This includes collecting data on specific use cases, frequency of use, and devices (such as laptops or mobile devices), evaluating whether its current functionalities align with industry needs for assessing energy theft and TDIS submissions, and reviewing the suitability of its current platform to identify preferred future delivery mechanisms (e.g. web or app-based). This approach aims to inform potential enhancements or a comprehensive upgrade, ensuring a consistent and reliable tool that can be accessed and used effectively across multiple operational scenarios and devices for the benefit of all Parties.
Problem Statement
The current lack of clarity around the usage, effectiveness, and suitability of the energy theft calculator is leading to inconsistent assessments and reporting across the industry. This ambiguity hinders the identification and sharing of best practices, creates an uneven playing field among Parties, and may result in inconsistent outcomes for consumers. Additionally, it limits the tool’s potential to support robust, court-ready evidence ahead of the Energy Theft Unit (ETU) and Referral Assessment Service (RAS) launch. A lack of transparency may also discourage Parties from raising concerns, further impeding improvement and compliance.
