BSC Issue 123: MHHS Asset Metering Review

Elexon has launched BSC Issue 123: MHHS Asset Metering Review and is seeking industry participants to join the Issue Group. The review will examine how Asset Metering arrangements should operate under the Market-wide Half-Hourly Settlement (MHHS) framework, ahead of key implementation milestones.

The Issue will consider whether existing Asset Metering roles, including HHDC, MOA and AMHHDC, remain appropriate under MHHS arrangements or whether they should be retained, extended, restructured or replaced. It will also assess whether Asset Metering data exchanges should migrate from the Data Transfer Network (DTN) to the Data Integration Platform (DIP), reflecting preferences previously identified by MHHS industry experts.

In addition, the review will address known process gaps relating to the Loss of MSID Pair Allocation and Loss of AMSID Pair Allocation arrangements, including the development of a clearer escalation route where parties are unable to reach agreement. The Issue Group will also assess impacts on existing BSC arrangements, qualification requirements, industry systems and participating organisations.

For AMO members, this review is particularly significant as it has the potential to reshape Asset Metering governance, associated market roles, industry data flows and operational responsibilities under MHHS. The outputs may ultimately lead to BSC Modifications, Change Proposals and wider industry changes affecting meter operators and other market participants.

Elexon expects the first Issue Group meeting to be held in early September 2026 and is encouraging interested stakeholders to participate. AMO members with an interest in Asset Metering, MHHS implementation, market roles or industry data exchange arrangements may wish to consider joining the Issue Group or subscribing to the workgroup mailing list to help influence the future design of these arrangements.

REC Moves to Integrate Theft Issues Group into Wider Change Governance Framework

The Retail Energy Code (REC) has outlined plans to integrate its Theft Issues Group (TIG) into the broader Change Issues Group (CHIG), marking a shift in how energy‑theft matters will be governed across the sector.

Established in April 2024, TIG has played a significant role in developing several major Energy Theft‑related Change Proposals (CPs). While these efforts have delivered successful outcomes, REC has noted a recent decline in the number of new theft‑related Issues and CPs, prompting a review of how best to manage future work in this area.

CHIG, a well‑established and highly attended forum, now provides end‑to‑end support for REC Change Issues, including solution development, industry engagement, and governance processing. Many existing TIG participants already contribute actively to CHIG discussions.

Transition of Energy Theft Issues to CHIG

Under REC’s proposal:

  • All future Energy Theft Issues will be managed through CHIG.
  • CHIG will feature a standing agenda item dedicated to Energy Theft.
  • Issue‑specific working groups will be formed where deeper specialist focus is required—for example, work underway on I0265 Theft Calculator Usage & Suitability Assessment.
  • TIG may be re‑established in the future should issue volumes or industry needs increase.

The REC Code Manager expressed thanks to TIG members for their contributions to date and emphasised that collaboration will continue within the CHIG environment.

Concerns Raised by TIG Participants

During the recent TIG, several attendees shared concerns regarding the transition:

Some participants highlighted that theft specialists who routinely support TIG may not have capacity to attend monthly CHIG meetings, risking a reduction in expert input. REC clarified that attendance would only be required for the Energy Theft agenda slot, not the entire CHIG meeting.

Concerns were raised that discussions could become less candid in a larger forum—particularly if Ofgem or other wider audiences are present. TIG has historically provided a space for more open exchange on sensitive theft matters.

Several members questioned whether fewer issues are being raised because key stakeholders may not be participating, rather than because issues do not exist.

Participants noted that best‑practice sharing across the theft community is already limited, and some fear that integration could further reduce opportunities for industry learning.

The Chair of the UK Revenue Protection Association (UKRPA) also expressed similar concerns during the discussion, echoing members’ observations on the importance of maintaining specialist insight and open dialogue.
However, the UKRPA Chair acknowledged the rationale behind REC’s decision and reiterated that the UKRPA continues to provide a dedicated forum for:

  • sharing best practice,
  • discussing operational theft challenges,
  • supporting industry collaboration, and
  • offering technical input to RECCo and the REC Code Manager when required.

Its Chair emphasised that the UKRPA remains committed to working closely with REC to help the industry address Energy Theft and safety issues effectively.

New Asset Condition Code C21 to Streamline Meter Installations from February 2026

A significant improvement to service termination reporting is set to come into effect on 27 February 2026, following industry approval of REC Change R0244. The change introduces a new asset condition code—C21: Non‑standard PME Connection Arrangement—into the Service Termination Issue Reporting Guidance (STIRG). The update is expected to reduce aborted meter installation visits and improve operational efficiency across the sector.

Addressing Long‑standing Installation Barriers

Historically, scenarios where the meter supply neutral was taken from a shared neutral/earth (N/E) block were recorded under B07, a code requiring the job to be stopped and the Distribution Network Operator (DNO) to attend—even when no network intervention was necessary. This process resulted in avoidable delays, extra costs, and poorer customer journeys.

The introduction of C21 provides a more accurate reporting route for these non‑standard PME arrangements, enabling Meter Operator Agents (MOAs) to continue installations safely without requiring automatic escalation. The update aligns data guidance in DI51121 / J1824 with current field conditions. 

Industry Support and Expected Benefits

The proposal received unanimous backing from respondents representing both DNOs and other industry parties. Feedback highlighted the value of reducing unnecessary aborts, cutting back on unproductive DNO callouts, and improving installation success rates—particularly important during large‑scale programmes such as meter exchanges and legacy equipment removals.

Responses indicated varied implementation lead times across organisations, ranging from just a few days to several months. To support a consistent, coordinated rollout across all affected parties, a six‑month lead time was agreed upon.

Governance and Implementation

The change was reviewed and approved through the REC Metering Expert Panel (RECMEP), with updates made to STIRG guidance and associated legal drafting. The governance process confirmed that the change is low‑cost, proportionate, and beneficial for both operational performance and consumers. 

Implementation will follow a “big bang” approach on 27 February 2026, ensuring all market participants adopt the updated reporting code simultaneously. 

A Step Toward Greater Efficiency

The introduction of C21 marks a practical improvement in addressing real‑world installation scenarios. By reducing unnecessary site visits and simplifying how non‑standard PME arrangements are reported, the change is ex

RECCo Launches Annual Rating Initiative for Metering Agents

The RECCo Performance Assurance team has announced the development of an Annual Rating Initiative designed to introduce a transparent, fair, and constructive peer comparison system for Metering Agents, including MEMs, MAMs, MOAs, EMOs, and AMIs. This new framework builds on the established system for Suppliers and DNOs, aiming to benchmark compliance, encourage positive behaviours, and support continuous improvement across the market.

Consultation Period Now Open

The consultation period runs from December to February, providing stakeholders with the opportunity to refine assessment criteria. An impact assessment will be published shortly via the REC and shared with members. Draft ratings are scheduled for release between July and August, followed by a query window for parties to review and challenge provisional ratings. Final market-wide scores will be published in September, after the query window closes. Criteria will be reviewed annually to ensure relevance and fairness.

Assessment Criteria

For MEMs, ratings will focus on:

  • Data Quality: High-quality data transfer to support market performance.
  • Compliance with CoMCoP: Timely audits and addressing all findings, not just minimum compliance.
  • Consumer Experience: Responsiveness and prompt issue resolution.

For MAMs and MOAs, criteria include:

  • CoMCoP Audit Timeliness: Delays negatively impact ratings.
  • Action Plan PATs: Issuance and progress on action plans, especially for data cleanse.
  • Maintenance of Qualification: Delays in submission are penalised.
  • Persistent Performance Issues: Escalations or repeated poor engagement reflected in ratings.
  • CME Condition Breach: Breaches affect ratings proportionally to severity.

Ratings will range from “No Material Weakness” to “Severe Weakness”, with the lowest score across criteria determining the overall rating. Discussions are ongoing to better recognise positive performance and refine terminology to avoid negative connotations.

Controls and Engagement

Key measures include:

  • Query Window: Parties notified of provisional ratings and reasons, with time to respond and provide evidence.
  • Education: Targeted webinars and published guidance on criteria and methodology.
  • Annual Review: Stakeholder input sought to ensure relevance and fairness.

Key Discussion Points

  • Consistency and Fairness: Concerns about consistent application of CoMCoP and audit processes.
  • Recognising Positive Performance: Calls for better acknowledgement of those exceeding expectations.
  • Transparency and Commercial Impact: Phased approach to visibility to balance transparency with sensitivities.
  • Continuous Improvement: Iterative process offering opportunities for feedback and refinement.

Representatives from RECCo will attend the General Meeting on 26 February 2025 to present an update and answer questions.

Ofgem Approves Urgent Changes to the Smart Energy Code: Protecting Connectivity for Thousands of Smart Meter Users

On 3 December 2025, Ofgem announced its decision to approve a critical modification to the Smart Energy Code (SEC), known as SECMP308. This change comes at a pivotal moment for the energy sector, as it addresses the growing issue of “Out of Region” Communications Hubs (CHs) installed in areas where service providers are not contractually obliged to maintain connectivity. The modification was proposed by the Data Communications Company (DCC) and granted urgent status by Ofgem, reflecting the pressing need to safeguard smart meter functionality for tens of thousands of consumers across Great Britain.

Smart meters rely on the Smart Meter Wide Area Network, which is divided into regions based on the technology used. The North region, for example, utilises Long Range Radio, while the Central and South regions depend on cellular infrastructure. The SEC requires that the correct variant of Communications Hub is installed according to the region, but in recent months, a significant number of CHs have been installed outside their permitted regions. This has led to a situation where, without intervention, connectivity for these devices would be removed from 1 January 2026.

The consequences of such a disconnection would be severe. Ofgem’s decision document highlights that around 46,000 consumers would be affected, including over 16,000 on prepayment and more than 21,000 on the Priority Services Register (PSR). Many of these individuals rely on remote top-ups and support provided by smart meters, and losing connectivity could result in disconnection, particularly during the winter months when energy needs are greatest.

To address this, SECMP308 establishes a formal mechanism for maintaining connectivity for existing Out of Region CHs. DCC will enter into contractual agreements with service providers to ensure continued service for these devices in the North region. This arrangement will remain in place until 1 June 2026, giving suppliers time to replace the affected hubs with compliant alternatives. The modification also introduces a new charging mechanism, with suppliers required to pay up to ÂŁ500 per Out of Region CH in their portfolio. If the pace of replacements increases and costs exceed this cap, additional expenses will be socialised across all suppliers and network providers.

The decision to approve SECMP308 was not taken lightly. The SEC Change Board, after considering the proposal and responses to a short consultation, recommended its approval, noting that it would better facilitate the objectives of the Smart Energy Code. Ofgem agreed, concluding that the modification would ensure the efficient provision and operation of smart metering systems, enable DCC to meet its licence obligations, and support consumers in managing their energy use.

Industry stakeholders raised concerns about the fairness of the charging arrangements, particularly for suppliers who had not installed Out of Region CHs and for Distribution Network Operators who benefit from network health data provided by these hubs. Ofgem acknowledged these concerns but emphasised that the situation had arisen due to continued installations in contravention of SEC requirements. The regulator stressed the importance of suppliers acting quickly to replace Out of Region CHs and avoid unnecessary charges.

Ultimately, Ofgem’s decision prioritises the needs of vulnerable consumers and the continuity of smart meter services. By approving SECMP308, the regulator has ensured that thousands of households will retain access to essential energy services through the winter and into the new year, while giving the industry time to implement a permanent solution.

Change Report Published for Consultation: Clarification of SIP Qualification Requirements (R0270)

27 November 2025 – The Change Report (For Consultation) regarding the clarification of Safe Isolation Provider (SIP) Qualification Requirements has been published and is now available for review by the Metering Expert Panel.

The metering expert panel will formally consider the report at its meeting on 10 December 2025. Stakeholders are invited to submit any comments on the report by 23:59 on 5 December 2025.

Background

The Change Proposal, previously referenced as I0270 – Clarification of SIP Qualification Requirements, addresses an unintended consequence from a previous change (REC Change Proposal R0064) that inadvertently excluded Electricity Metering Operatives (EMOs) from qualifying as SIPs. Currently, REC Schedules 1, 14, and 15 state that only Qualified Meter Operator Agents (MOAs) can be SIPs. The proposal seeks to ensure that EMOs are also eligible, thereby broadening the pool of qualified SIPs and preventing potential shortages or the risk of unqualified individuals undertaking SIP works.

Timeline and Next Steps

The following REC Issue has now progressed into a REC Change Proposal:
R0207 Clarification of SIP Qualification Requirements – REC Portal
As a result of this progression, I0270 will now be referenced as R0270. All existing and future documentation can be accessed via the existing links. This Change Proposal will now proceed through the Change Proposal process in line with its Proposal Plan.

The proposal is currently at the Proposal Plan stage, with the following milestones:

  • Definition Phase: 16 September – 30 November 2025
  • Code Manager Initial Assessment: September 2025
  • Solution Development: October – November 2025
  • Legal Review: November 2025
  • Change Proposal Stage: 1 December 2025 – 10 February 2026
  • Business Case Assessment: December 2025
  • Consultation: December 2025 – January 2026
  • Solution Refinement: January – February 2026
  • Final Determination: February 2026
  • Voting: 11 February 2026
  • Appeal Window: 12 – 26 February 2026

 

REC Publishes Q&A and Slides for I0230 & I0261 Session – Responses Invited

The Retail Energy Code (REC) has published the slide deck and Q&A responses from the joint I0230 and I0261 Q&A session, held on 19 November 2025. These materials are now available to all stakeholders via the REC Portal.

Session Overview

The session, hosted by he REC Code Manager team, addressed two key REC issues impacting Meter Asset Providers (MAPs) and Meter Operator Agents (MOAs):

  • I0230 – D0303 Flow Following MHHS Design Changes:
    The “Effective from Settlement Date” (J0049) in the D0303 flow has changed from mandatory to optional, following Market-wide Half-Hourly Settlement (MHHS) design changes. This adjustment may impact MAPs’ ability to accurately invoice suppliers, as critical data may not always be available. 

  • I0261 – Addition of Export Flag in D0303 Flows:
    The rise in microgeneration has led to the creation of Export MPANs, complicating installation flows and increasing manual checks for MAPs. The proposal seeks to introduce an export flag in the D0303 flow to streamline operations and reduce errors.

Published Materials

The following documents are now available on the REC Portal:

I0230 I0261 Q&A session

Joint Information Request – How to Respond

A joint information request covering both I0230 and I0261 has been published and can be accessed from the Information Request Register on the REC Portal. 

Responses are invited by 05 December 2025.

Key Q&A Highlights

  • Accessing the EES API:
    MAPs can apply for access via the REC Portal under Organisation Management > Make an Application. Approval typically takes around three months, subject to completion of information security and data protection assessments.

  • Data Privacy:
    Portfolio extracts can exclude address information if required, and MAPs can request only the data they need. Address is an allowed data item as set out in the REC Data Access Matrix.Change Dependencies:
    The change to add Supplier Effective From Date to the IF-036 Market Message has been descoped as a REC Change, as IF-036 is owned by the Balancing and Settlement Code (BSC). Any future changes will require further coordination.

 

I0282 Return of Legacy Meters

I0282 is a Retail Energy Code (REC) change proposal focused on the challenges associated with the return of non-smart (legacy) electricity meters to Meter Asset Providers (MAPs). As the energy sector transitions to smart metering, thousands—if not millions—of legacy meters are being removed and transported across the country. This process has raised significant questions about cost, environmental impact, and operational efficiency.

Key Issues

  • Cost and Environmental Impact: The transportation and handling of legacy meters incur substantial costs and contribute to environmental concerns due to the scale of logistics involved.
  • Unclear Requirements: It is not always clear whether all MAPs require the return of old meters, leading to potential inefficiencies and unnecessary movements.
  • Recycling and Disposal: There is uncertainty around whether these meters are being recycled, disposed of responsibly, or simply stored. The net value of returning and disposing of old meters remains unclear.
  • Operational Complexity: Storage providers often struggle to identify the original MAPs, especially when company names have changed over time, complicating the process of return and disposal. 

Proposed Solution

The I0282 proposal suggests several improvements:

  • Streamlining the Process: Simplify the return and disposal process to reduce unnecessary transportation and handling.
  • Environmentally Responsible Disposal: Encourage recycling or environmentally friendly disposal of legacy meters, rather than defaulting to return.
  • Clearer Commercial Arrangements: Establish more transparent agreements between parties to clarify responsibilities and reduce costs.
  • Direct Collection by Waste Management: Where possible, allow waste management companies to collect meters directly, bypassing unnecessary steps. 

Industry and Consumer Impact

  • Industry: The proposal primarily affects Distribution Network Operators, Energy Suppliers, MAPs, and Metering Equipment Managers. It references the Consolidated Metering Code of Practice (CoMCoP), which currently requires meters to be returned to MAPs unless alternative arrangements exist.
  • Consumers: No direct impact on consumers is anticipated, but there are potential environmental benefits from improved recycling and disposal practices.

Next Steps

I0282 will be presented by the Code Manager at the next REC Change Issues Group meeting on 04 December 2025 (10:00–12:00). Stakeholders are encouraged to attend and contribute to the discussion on how best to address these challenges and implement more sustainable practices.
