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.

Problem Statement
There is a gap in the provision of the REC that means that Energy Theft data is not able to be shared with the BSCCo for the purposes of use within Settlement. Without the ability to have this data shared with them, the BSCCo are unable to confirm that all Energy Theft data has been correctly entered into Settlement.

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.

Problem Statement
This Issue was raised by RECCo’s Data Protection Officer who noted that the addition of the extra layer of approval delays the process for Parties in processing this data, and it does not align with similar changes for the Balancing and Settlement Code (BSC), where board approval is not required.

Latest Update
This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
Within MHHS SIT there is a scenario where the LDSO generates a D0139 to the MS for a PPM but the requirement is for the MS to generate a D0179. There is a gap in the D0179 data required and that provided on the D0139. 21.5.1 & 21.5.6 under Schedule 14 states that where the DNO changes the energisation status, within 3 WD of changing the energisation status the DNO will send the D0139 or the D0179(21.5.6) to the MS and then the MS will generate the D0179 to the Supplier(21.5.6). Currently, the LDSO only generates the D0179 to the Supplier but not to the MOP and the only change under MHHS is to add the new variant MSS.

Problem Statement
DNOs and MOAs cannot fulfil their full obligations listed in Schedule 14 Metering Operations as there missing Scenario Variants in the Data Specification preventing them from sending the D0179 to all required Parties. This alternate solution proposes the removal of the D0179 from the legal text and the D0139 to be used in all scenarios.

Problem Statement
Where a Network Party attends a site where Energy Theft has taken place, the Metering Asset may have been tampered with, and will therefore be unsafe. The Network Party, in the process of making the Metering Asset safe, will by necessity resolve any tampering. The removal of evidence of tampering is an issue for Energy Suppliers, who need this evidence to make claims under the TDIS.

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.
