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.

19/06/2026 - Change Report Re-Plan V4.0 approved by Change Panel.
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.

27/05/2026 - the Technical Expert Panel voted to approve R0261 for implementation in November 2026. The appeal window closed on 12 June 2026.
Summary
The Market Message (D0303 / MM00240) responsible for informing Metering Asset Providers (MAPs) of Metering Equipment installation is generating a lot of queries and exceptions due to Export MPAN creation. This is requiring MAPs to manually investigate whether a D0303 showing a Metering Asset being installed against a second Metering Point is a correction or the creation of an Export MPAN that can be ignored. Due to the growing uptake of microgeneration this is a problem that is growing in volume.

Problem Statement
MAPs must manually check D0303 Market Messages received with duplicated Metering Equipment (e.g. duplicated Meter Serial Number) to ensure they hold the correct Metering Equipment against the correct Metering Point. For Export Metering Points using the same Metering Equipment as the Import Metering Point, this manual check results in no action needing to be taken.

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.
