Latest Update
21/07/2026 - On 21 July 2026, the REC Change Panel voted to approve the Change Report (Proposal Plan) for I0325.
Summary
The REC was updated, primarily through R0209 and R0241, to add requirements that support the transition to, and enduring operation of the MHHS arrangements. As part of the transition, each impacted Metering Point will be migrated using processes defined in Codes, including the REC. Once this migration activity is complete, the legacy and transitional arrangements will become redundant and should be removed from the REC to support its efficient operation

Problem Statement
Retention of redundant obligations within the REC would make it more complex to navigate for Market Participants and could cause confusion on the obligations that are in effect to support the efficient operation of the Great British Energy retail market. It is also worth noting that until Ofgem formally closes the MHHS Significant Code Review (SCR), this REC Issue could potentially impact that SCR.

Summary
The REC Metering Operations Schedule has limited distinction between the activities for import and export metering. These provisions were not specifically developed to support a market with high volumes of small-scale microgeneration with shared metering assets for import and export.

Problem Statement
The current lack of explicit wording in the Metering Accreditation Schedule of both a desktop and site audits that need to be completed one year after the initial accreditation, and then every two years for renewals introduces ambiguity for future audit delivery undertaken under CoMCoP as it creates a gap between operational practice and the codified baseline. This could potentially lead to inconsistent approaches by Parties, which in turn could reduce the consistency, predictability, and effectiveness of the industry’s audit and assurance framework.

Summary
DCUSA change DCP467 has been raised to propose that Category A and B defects reported currently using the Asset Condition Report (D0135) or phone call to the DNO, should instead be reported via an online reporting tool where the DNO has one available. This is expected to have impacts to the REC.

Problem Statement
Where DNOs have enhanced reporting tools for Category A or Category B situations, it is not mandatory for Parties to submit reports using this method. This may lead to a detrimental Consumer experience, as it is limited what information can be provided over the telephone or via Market Message (e.g. it is not possible to provide photographs of the situation).

Summary
The current timetables in REC Schedule 14 Metering Operations sections 15.6 and 30.6, where an Electricity Metering Asset requires commissioning in accordance with BSC Metering CoP 4 and the Measurement Transformers are owned by the DNO, or in 15.7 and 30.7 where the Measurement Transformers are not owned by the DNO, may no longer be fit for purpose post the implementation of MHHS Milestone M16, where the Settlement timetable reduces the RF run to 4 months.

Establishing the Safe Isolation Provider (SIP) as a Standalone REC Party

Latest Update
21/07/2026 - An Update to Plan has been approved by the Change Panel on 21 July 2026.
Summary
This proposal recommends the formal recognition of the Safe Isolation Provider (SIP) as a standalone Party under the Retail Energy Code (REC). This aligns with the direction set out in Ofgem’s recently published Strategic Direction Statement (SDS), which explicitly calls for the establishment of SIPs as a standalone Party role. The aim is to address the growing scale of unregulated SIP activity, mitigate associated consumer safety risks, and ensure the metering industry is equipped to support the UK’s Net Zero ambitions. By enabling easier access to certified SIPs, this change will enhance consumer protection, accelerate low-carbon technology deployment, and improve operational efficiency across the energy sector.

Problem Statement
The current SIP framework poses several risks: - Consumers, MEMs and unaccredited practitioners’ safety. Unaccredited and unregulated isolation work increases the risk of unsafe installations and potential harm to Consumers. NAPIT highlighted to RECCo and DESNZ that 17 and 13 unregulated practitioners respectively died in 2023 and in 2024 due to unsafe isolation. With the right Party undertaking this work, there would also be less safety issues for the Consumer at their premises; - Inequity. Independent Installers face longer wait times compared to supplier-led installations, creating a two-tier system; - Low competitive market. Currently prospective Parties can be put off from applying to be a SIP as it appears they would need full MEM Accreditation which is often too far outside their current business operating model. Providing SIPs with their own pathway and requirements could result in more Parties becoming SIPs and therefore giving Consumers more choice in their provider; and - Decarbonisation delays. The inability to scale SIP capacity undermines the timely deployment of LZCTs, threatening Net Zero targets.

Latest Update
This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
REC Schedules 1, 14, and 15 all note that in order to Qualify as a Safe Isolation Provider (SIP), the Party needs to be a Qualified Meter Operator Agent (MOA). It has since been determined that Qualified Electricity Metering Operatives (EMOs) should also be able to Qualify as SIPs.

Problem Statement
Requiring SIPs to be fully Qualified MOAs may be hindering smaller Parties who wish to be SIPs from Qualifying under the REC. This in turn may be reducing the number of Qualified SIPs in the market for Consumers to choose from or causing Consumers inadvertently to contract with people who are not Qualified SIPs to carry out SIP Works.

Latest Update
12/08/2026 - the Proposer has chosen to withdraw this Issue as MHHS means many of the effective dates are being updated as per the original business case so the change is no longer required.
Summary
On a switch many of the effective dates within EES default to the switch date. This includes energisation status. It means EES users that don't have access to the meter technical details do not know the actual date the status changed.
