22/09/25 - This Change Proposal has been implemented as part of the MHHS M8 22 September 2025 REC Release.
Summary
The Electricity Smart Meter Equipment (ESME) ID is a unique identifier that provides a designation for a Smart Meter. Electricity Retail Data Agent (ERDA) systems were updated as per the requirements in R0033 to not allow for multiple incidences of an individual ESME ID to be registered, and reject the update, even when a second incidence of an ESME ID would be legitimate, for example in the case of a re-use of Metering Asset or a crossed meter. This Issue seeks to resolve this feature of the ESME ID validation while maintain data accuracy.

Problem Statement
ERDA data validation on the ESME ID Data Item in the D0312(MM00256) Market Message is imperfect, and can result in invalid rejections. This occurs when more than one incidence of an ESME ID is passed through individual ERDA system, as it only allows for a single occurrence, even if historic ones have been end-dated. In situations where a Metering Asset has been re-used, thus re-using the ESME ID, a rejection will occur, in an example of an unintended functionality of the validation system.

Latest Update
20/05/2025 - the Code Manager has withdrawn this Issue, as there are no adequate solution options and minimal Consumer detriment. The adoption window has closed.
Summary
REC Parties have told the Code Manager that they are seeing multiple registrations attempts (10 plus attempts on consecutive days in some instances) on individual MPxNs. They are concerned about Consumer detriment as those trying to switch are not getting time to review objection related communications from their current Supplier to allow them to act and resolve the issue. This was initially presented as a non-domestic issue, but initial Code Manager investigations have also highlighted potential concern around proposed domestic transfers as well. There is also a risk of Party Performance impacts with initial analysis flagging potential impacts on Performance Assurance Risk Drivers, 8.9, 8.10 & 8.11.

Problem Statement
Non-Domestic Consumers are having their Switch experience affected by multiple Objection attempts following a single initial attempt to register for their supply by a prospective gaining Supplier. This results in Consumer detriment, as multiple Objections result in repeated rounds of communications to the Supplier. This results from automated Registration systems employed by Non-Domestic Suppliers.

15/07/2025 - The Code Manager has rejected Issue I0213. This Issue has been deemed out of scope of the REC and has been rejected following a legal review. This decision was ratified by the REC Change Panel at their meeting on 15 July 2025.
Summary
Presently only industry parties can raise the matter of non-compliant or unwarranted objections activity that a supplier may be participating in. This Issues has been raised to request RECCo to consider accepting notice and evidence (that can be acted upon) from qualifying 'non industry' parties, from third party consultants and brokers.

Solution Development
Proposed solution summary
- I0213 has been raised with a suggestion that the Code Manager should consider accepting notice and evidence from qualifying non-industry Parties, including Third Party consultants and brokers (Third Party Intermediaries (TPIs)). A possible solution for this may include a new submission page, or form, on the REC Portal, that would allow Third Parties to submit evidence of non-compliant Objection activity.
Problem Statement
There is currently not a method for Third Parties, who may be involved in the Switching process, to report non-compliant Objection activity. Non-Compliant Objection activity can result in time consuming procedures for Consumers, creating unnecessary engagement with Energy Suppliers, and may result in a financial burden.

On 07 August 2026, Ofgem approved this Change Proposal, in line with the recommendation made by the Code Manager and the Metering Expert Panel. R0207 will be implemented on 06 November 2026.

Summary
BSC Mod 459 and REC CP R0144 were raised to allow different MOAs to be appointed for the import and export MPANs on a shared meter. One of the justifications for this was to stop export suppliers being charged inflated rates. Both changes have been placed on hold due to the MHHS Programme so this change has been raised to specifically resolve the charging issue.

Problem Statement
Where the same electricity Metering Asset is being used for the measurement of Import and Export for more than one Metering Point, the Export MOA must be the same as the Import MOA. This may result in uncompetitive charging by the MOA, as the Export Supplier has no choice in their appointment.

Latest Update
13/05/2026 - The REC Code Manager is establishing a new REC working group to support the progression of I0200 – Review of the REC’s Address Management Service. If you would like to attend the I0200 Working Group, please register your interest by contacting the Code Manager at change.management@recmanager.co.uk. The first meeting will take place in June 2026, with the exact date and time to be confirmed in due course and communicated via the REC Change Bulletin and via email to all those who register their interest.
Summary
Having the incorrect address can lead to a range of Consumer issues, including switching, billing and meter reading problems. The Meter Point Location (MPL) and Retail Energy Location (REL) have been added to the Code to resolve this issue. Whilst there had been progress resolving address data issues, there is not currently a mechanism to establish Code level targets for address improvement, resulting in around 2.8 million unmatched addresses.

Problem Statement
There is no time scale by which Energy Suppliers need to have submitted the Registration De-Activation Request or for electricity to have raised a query with the Distribution Network Operator (DNO) if they believe the Metering Point should not be Disconnected. This raises difficulties for the REC Performance Assurance team when monitoring and enforcing this obligation.

This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
The drafting in Schedule 28 – Related Metering Points has been updated for Market-wide Half Hourly Settlement (MHHS), allowing related Metering Points to be in a Status of Operational or Created in MPRS, as long as all Related Metering Points are in the same Status. This Change Proposal suggests allowing Secondary Metering Points with a Status of Created to be linked to Primary Metering Points with a Status of Operational, for MHHS migrated Metering Points only.

Problem Statement
By not allowing Primary Metering Points with a Status of Operational to be linked to Secondary Metering Points with a Status of Created, where the Metering Points have migrated into the MHHS arrangements, full advantage is not being taken of the MHHS functionality of automatically appointing agents to Secondary Metering Points.

This is a Housekeeping Change Proposal subject to the Housekeeping Change Proposal process, rather than the standard change process. The nature of the change is that it makes non-material changes to the REC Products to correct typographical and consistency errors.
