Summary
While undertaking the CRS Improvements Project, RECCo, the Code Manager and DCC completed a review of current reporting that is generated as part of REC Obligations. As part of this review, Address Management-related reports were identified that are not fit for purpose. These reports are produced only for DCC internal consumption. The identified reports are captured in the Performance Assurance Report Catalogue (PARC). As such, DCC proposed raising a REC change to have these removed from the PARC (they will still be available on an ad-hoc on request basis).

Summary
Quae cum dixisset, finem ille. Quamquam non negatis nos intellegere quid sit voluptas, sed quid ille dicat. Progredientibus autem aetatibus sensim tardeve potius quasi nosmet ipsos cognoscimus. Gloriosa ostentatio in constituendo summo bono. Qui-vere falsone, quaerere mittimus-dicitur oculis se privasse; Duarum enim vitarum nobis erunt instituta capienda. Comprehensum, quod cognitum non habet? Qui enim existimabit posse se miserum esse beatus non erit. Causa autem fuit huc veniendi ut quosdam hinc libros promerem. Nunc omni virtuti vitium contrario nomine opponitur.

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
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.

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
As part of R0224, the technical solution creates a CSS replica (read-only) database view that can be used by RECCo and the REC Code Manager to generate reports on demand for market participants. For users to be able to access this database and request generation of the appropriate reports, this change is seeking to develop that front end portal capability to manage user’s requests and allow for completed reports to be downloaded via the REC Portal.

12/05/2026 - The Code Manager have developed a solution which has been live since 05 May 2026. More detail can be found on the REC Portal Wiki. A Closure Report has now been published, and this Issue has now been classed as resolved.
Summary
The RegistrationId (DI90043 / DI849) is required by SMRS to be included in the IF-031 'Supplier Agent Appointment Request' Market Message to allow the SMRA to process the appointment request. However not all Suppliers hold the RegistrationId for all Meter Points, in particular those that have not undergone a Registration managed by the Central Switching Service (CSS)

Proposed solution summary
- As part of the solution for REC Issue I0296 - Registration Id Required for MHHS Appointments the REC Code Manager have developed a process to provide Energy Suppliers the Registration Id for Metering Points that have not been through a Central Switching Service (CSS) Registration Managed Switch. This is to allow Energy Suppliers that may not hold the Registration Id for these Metering Points to populate the Market-wide Half Hourly Settlement (MHHS) Agent Appointment Messages required to initiate a MHHS Migration.

Problem Statement
Not all Energy Suppliers hold the RegistrationId for all Meter Points, particularly those Meter Points that have not gone through a Switch, i.e. have not undergone a Registration managed by the CSS. The RegistrationId is currently only available where a Metering Point has been through a CSS managed Registration. Without the RegistrationId available to Energy Suppliers, not all Metering Points will be able to migrate putting the MHHS Migration and Milestone M15 at risk.

03/07/2026 - The Service Provider Impact Assessment is ongoing and expected to be completed by 07 August 2026.
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.
