Latest Update
08/04/2026 - The Closure Report was presented to the REC Metering Expert Panel at their meeting on 08 April 2026. The Issue has now been classed as resolved.
Summary
The issue identified is that current arrangements require or assume that legacy Meter Asset Providers (MAPs) take back old, non Smart Meters once they are removed from Consumers’ Premises, even though many of these meters are obsolete, cannot be reused, and ultimately require disposal. This has resulted in large volumes of legacy meters being transported across the country between storage providers and legacy MAPs, creating unnecessary cost, administrative burden, and environmental impact. Storage providers are issuing extensive lists of Meter Serial Numbers (MSN) to try to establish meter ownership, and legacy MAPs must manually verify these details. This process has been made more difficult by historical changes in company names and ownership structures. Once ownership is confirmed, the meters are frequently transported to the legacy MAP only for them to arrange disposal, which provides no net value and simply adds further transportation and handling costs.

Problem Statement
The process for handling removed legacy non Smart Meters is inefficient and environmentally costly, with unclear ownership, unnecessary transport, and no established recycling route. A consistent, sustainable disposal solution is needed to reduce waste, simplify operations, and clarify the management of any scrap value.

Summary
CSS Market Messages sent by the Central Switching Service (CSS) to Switching Data Service Providers (SDSPs) are either not being received, being received after Gate Closure, or are being received out of the order that they were originally sent in. This Issue originally aimed to extend the Refresh functionality, implemented for the Gas Retail Data Agent (GRDA).to the Electricity Retail Data Agent (ERDA). Following solution development for I0281, it was agreed that the Refresh functionality would be made available for all Market Participants in receipt of the in-scope messages.

Problem Statement
CSS messages are not received by the SDSPs in the order in which they were originally sent, or after Gate Closure, so it can be difficult to detect and often requires significant manual effort to resolve. This issue can directly impact Consumer switching experiences, causing disruption and possible delays in a switch.

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
06/11/2025 - Following discussions at the Change Issues Group on 06 November, a REC guidance will be developed to support the resolution of this Issue after which it will be classed as resolved.
Summary
It has been identified by the MHHS Data Cleanse Working Group (DCWG) that around 9,000 existing Metering Point Relationships include Metering Points that would migrate into different Market-wide Half Hourly Settlement (MHHS) Market Segments. The majority of these are where one Metering Point has a Traditional meter installed (Smart Segment) and a Related Metering Point has an Advanced meter (Advanced Segment). This situation is currently valid but in MHHS would cause two problems. - SMRS would not be able to align the agent appointments, leaving secondary MPANs without agents and MHHS Migrations unable to fully complete.

Without considering this Issue, there will be a risk to the MHHS migration. Indeed, a Metering Point installed which does not match its Related Metering Point (for example a Relationship between a Traditional meter with an Advanced Meter) will not be able to fully migrate to MHHS arrangements.

21/07/2026 - Change Report (Proposal Re-Plan) approved at Change Panel
Summary
As per Section 13.4.18 of CoMCoP, retrieving gas pressure and capacity information from Transporters via the GT1 process can be time consuming for Energy Suppliers/MAMs and/or Consumers. The process of retrieving this information is inconsistent and service timescales are varied between transporters. Gas pressure and capacity information should be readily available through the Gas Enquiry Service to enable timely processing of site work and requests to enable MAM’s and Suppliers to appropriately service their customers.

Problem Statement
For some Energy Suppliers, MAMs and consumers, retrieving pressure and capacity information via the GT1 process can be time consuming. This is due to elements like response timescales and methods (batch responses vs individual responses) being varied among GTs. This ultimately has a negative impact on customers waiting on site work, such as a new connection, for example.

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.

Latest Update
This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
RECCo regularly reports on the performance of REC Service Providers in relation to their activities under the REC. However, there is currently no formal agreement to permit the publication of CRS performance measures between the CRS Provider and RECCo. Due to the multi-Party agreement, the REC does not specifically address the publication of this performance data. Instead, RECCo are operating under an informal understanding with the CRS Provider, which means there is a possibility that publication may be delayed or not agreed to in a given month. RECCo is dependent on the CRS Provider’s approval for each publication, which can cause delays. This approval could also be withheld at any point.

Problem Statement
Unlike REC Service Providers, there is currently no formal agreement in place between the CRS Provider and RECCo to publish details about the CRS Provider’s performance. RECCo is therefore dependent on the CRS Provider’s approval for each publication. Not only could there be delays in RECCo’s reporting, but the approval could also be withheld at any point, preventing RECCo’s reporting.

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.

This Change Proposal has been implemented as part of the June 2026 REC Release.
Summary
There is no requirement for energy suppliers planning fewer than 5000 Smart meter installations at domestic premises, within a calendar year, to survey Consumers for REC compliance purposes. Conversely, there is no minimum threshold in place for microbusiness installations, meaning that non-domestic suppliers are required to procure a suitably qualified, independent Smart Meter Installation Survey Organisation, at considerable cost, to survey what might be a very small number of customers.
