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.

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
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.

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.

30/04/2026 - The Code Manager has now published the I0240 - Scenario Guidance Document V2.0 on the REC Portal. This is available on the I0240 Proposal Page and the Market-wide Half Hourly Settlement Hub.
Summary
This Issue looks to address that when Meter updates are made during a Market Wide Half-Hourly Settlement (MHHS) migration, whilst the Meter Technical Details (MTDs) will be shared between participants, there will be no update sent to the Registration Service as the Gaining Meter Operator Agent (MOA) will not know that they need to send a D0312 (for reverse migration) or IF005 (for forward migration) and the Losing MOA cannot send the message.

Archive

Problem Statement
During MHHS migration, key Market Messages from the Losing MOA, such as D0312, IF005, D0205, and D0139, are rejected by the Registration Service, preventing updates to meter details and Energisation status. This creates a risk of data misalignment, as the Gaining MOA may not be aware that updates occurred and therefore cannot resend them.

04/06/2026 - on 02 June 2026, the Technical Expert Panel approved via ex-committee vote to place I0228 on hold, until the outcome of R0321 is known.
Summary
Electricity Suppliers believe there is a significant bottleneck to Export Metering Point creation, which is resulting in them feeling unable to offer Export smart products to a wider audience of Consumer and scale low-carbon technology. The most effective solution is an API within the Electricity Enquiry Service (EES) that allows the Electricity Supplier to request the creation of an Export Metering Point. This could work for both Electricity Suppliers and Distribution Network Operators (DNOs) ensuring that scalable solutions are applied at both sides of the process.

Problem Statement
A restriction of 50 Export Metering Points per DNO per day, with no two DNOs operating the bulk request process in the same way, is overly burdensome to Electricity Suppliers and creating a barrier for Consumers getting an Export Metering Point assigned to their Premise. This is ultimately harming the effort the reach Net Zero.

Latest Update
27/02/2025 - Change is now not being merged into any other changes and will proceed as a standalone change. A potential solution has been identified, but will be discussed for potential cross code impacts
Summary
Currently within Schedule 23 a Registration can only be undertaken on RMPs with an Operational or Dormant RMP Status, and not Terminated. Terminated is a status that the RMP is set to when the Meter Point Status is no longer operational or the site is isolated. It is right that these sites are not able to be Registered as there is a risk that Suppliers could inadvertently Register such Meter Points. We do have instances where such sites are stranded in defunct Supplier portfolios - and the Supplier no longer has the capability to take the relevant action to Deactivate the Registrations. This may because the operational staff have left and the business is in administration.

Proposal to Enable Broader Use of Retail Energy Location (REL) Data for Non-Switching Applications

Change Category
Change Path
Priority
Urgent
No
Latest Update
04/08/2026 - On 04 August 2026, the REC Change Panel approved the extension to plan for I0218. Service Provider Impact Assessments are in progress.
Summary
The problem being addressed is the current restriction within the Retail Energy Code (REC) that limits the use of Retail Energy Location (REL) data solely to switching purposes. This restriction prevents the full utilisation of REL data, which could be valuable for a broader range of operational, regulatory, and industry applications. Key Issues: - Currently, REL data, enriched with Unique Property Reference Numbers (UPRNs), is available via the Electricity and Gas Enquiry Services. However, Schedule 29 (Address Management) of the REC restricts its use to switching purposes only, preventing its use in other important industry initiatives. - Various industry stakeholders, including REC and non-REC data requestors as well as Ofgem (the regulator), have expressed a strong interest in utilising REL data for non-switching purposes. The restriction is seen as a limitation, especially for initiatives that require accurate property data to support wider operational and regulatory functions. - By restricting the use of REL data to switching, stakeholders are unable to fully leverage it for improving operational efficiency, regulatory compliance, and overall service delivery. Lifting this restriction would enable the wider use of REL data, allowing stakeholders to benefit from its full potential across various non-switching applications.

Proposed solution summary
- RECCo would acquire a AddressBase Core license from Ordinance Survey and the REC would be updated to allow parties to take full advantage of this data. In order for parties to use the REL data, they would need to acquire an AddressBase Premium license from Ordinance Survey or other relevant license.
Problem Statement
Retail Energy Location (REL) data currently is not permitted for uses such as improving customer service and streamlining internal processes. This means that stakeholders, such as Ofgem and data requestors, have been unable to benefit from this data and Consumers are therefore unable to benefit from the full potential use of their data.

13/05/2026 - The REC Code Manager is establishing a new REC working group to support the progression of I0200 – Review of the REC’s Address Management Service. If you would like to attend the I0200 Working Group, please register your interest by contacting the Code Manager at change.management@recmanager.co.uk. The first meeting will take place in June 2026, with the exact date and time to be confirmed in due course and communicated via the REC Change Bulletin and via email to all those who register their interest.
Summary
Having the incorrect address can lead to a range of Consumer issues, including switching, billing and meter reading problems. The Meter Point Location (MPL) and Retail Energy Location (REL) have been added to the Code to resolve this issue. Whilst there had been progress resolving address data issues, there is not currently a mechanism to establish Code level targets for address improvement, resulting in around 2.8 million unmatched addresses.
