Summary
It has been suggested that CHECK meters should not be sent within industry messages so the presence of this value within the valid set may not be required. This Issue has been raised to explore whether this assumption is correct, look at the existing/historic use cases industry have used the CHECK option for, if they are no longer valid and if so why not.

24/08/2026 The Change Report (Proposal Plan and Consultation) has been issued to Change Panel for ex-Committee decision. The proposed legal text can be found in the solutions section below.
Summary
RECCo is implementing the MSC solution in two phases to enable a swift restart of the MSC scheme, should a decision be made to recommence it. Phase one will enable data collection and the tracking of Supplier liabilities, allowing the scheme to commence before the full solution is available. Phase two will introduce the calculation and financial components.

Problem Statement
The REC currently requires statements relating to MSC to be provided to Energy Suppliers within 15 working days of the relevant MSC cycle. However, during the phased implementation of the MSC scheme, this timeframe may not provide sufficient time to reconcile the data collection while the calculation functionality is still under development.

Summary
Under the legacy/pre-MHHS arrangements the market is segmented by Measurement Class (MC) for settlement purposes which is not sensitive to the Meter type that is installed or is to be installed, meaning that the replacement of Traditional meters to either smart or Advanced metering equipment can be arranged without the need for the Change of Measurement Class (CoMC) process to be conducted concurrent with the meter exchange (MEX). Under MHHS, when a WC connection goes through a MEX from Traditional to Advanced, or from Advanced to Smart in the MHHS arrangements a new complexity is placed on suppliers because the CoSeg process must be tightly co-ordinated to a specified planned MEX date and processed through the MPRS within 3 Working Days of that date.

19/08/2026 - the Change Report (Proposal Plan) was approved by Change Panel. The Change Team and Performance Assurance team are working together to determine if there are performance assurance requirements for this change.
Summary
An incident where Network Parties did not submit Regulatory Alliances on time to the Central Switching Service (CSS) Provider, or did submit the Regulatory Alliances but did not action rejections from the CSS Provider in a timely manner, led to over 200 Consumers being delayed in Switching to their chosen Energy Supplier. This Change Proposal has been raised to review this process.

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
As part of the planning required to deliver Net Zero, Gas Distribution Networks (GDNs) are obligated to plan Industrial and Commercial (I&C) gas demand at a more granular, site-specific level. To meet this obligation, access to Standard Industrial Classification (SIC) Code data, matched to both Gas and Electricity Meter Point Reference Numbers, would provide a significantly improved understanding of I&C customers.

Latest Update
07/07/2025 - Change Report (Proposal Plan) has been approved by the REC Change Panel.
Summary
There is gap in the Erroneous Switch (ES) Performance Assurance reporting as the DTN does not provide MPXN level data up front. It requires individual ES permission before MPXNs are provided. However, CSS reporting does provide monthly MPXN level report. As such end-to-end monitoring of the ES process cannot be carried out at a MPXN level.
