Summary
Schedule 14 - Metering Operations currently holds obligations for a Meter Operator Agent (MOA) to send a D0383 ‘Notification of Commissioning Information’ to Electricity Suppliers, Distribution Network Operators (DNOs), Data Services and Data Collectors in certain process steps. The D0383 was not shared with these Parties in legacy arrangements, and there is no requirement for it to be sent to facilitate the MHHS arrangements. There are similar requirements to send the D0384 ‘Notification of Commissioning Status’ to these Parties, when it is only required by the Electricity Supplier. These requirements were introduced by the MHHS Design in error and need to be removed.

Problem Statement
Schedule 14 - Metering Operations puts obligations on MOAs which are both not required and impossible to fulfil (as the Scenario Variants to send the D0383 from the MOA to the Electricity Supplier, DNO, Data Service and Data Collector do not exist). There are similar problems for the D0384, which is only required to be sent from the MOA to the Electricity Supplier.

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).

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.

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.

Problem Statement
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.

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.

Summary

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.
