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.

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.

Problem Statement
The MHHS design does not mandate the use of SSC or support register-level TPR data for Smart and Advanced Meters, creating gaps in data availability for certain Settlement scenarios.

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.

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.

(Energy Supplier rather than Licensee, and Consumer rather than Customer) Updates to Principle 1 to provide clarity on what detail on TPI enumeration should be provided to the Consumer. Updates to the template Letter of Authority to remove the bullet allowing the TPI to sign and enter into new contracts. Text on compliance monitoring has been moved to be included under a new Principle 9.

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.
