18/03/2026 - An update to plan has been published for consideration at the Technical Expert Panel on 25 March 26.
Summary
As part of the impact assessment process for R0115, it was identified that it is very costly and time consuming to make reporting changes within the CSS architecture. As such, we would like to explore enabling agile reporting within the CSS ecosystem, by creating a functionality that consolidates all necessary data into a single, centralised database.

Problem Statement
Current CSS arrangements mean that REC Changes designed to facilitate access to CSS data are more onerous that they need to be. Current arrangements are costly and have relatively long lead-times. This Issue seeks to explore changing the way that the CSS data can be accessed.

22/09/25 - This Change Proposal has been implemented as part of the MHHS M8 22 September 2025 REC Release.
Summary
The process for Reconciliation of Unallocatable Transactions is set out in Section 10 of Schedule 11. During the most recent reconciliation delivery (the gas process from July 2024) several areas of improvement were identified, critically a lack of clarity regarding historic Supplier Licences and how to include or exclude them from the calculations. The Code Manager believes that this lack of clarity and past precedent would lead to material impact on one or more Party.

Summary
Housing Associations require an understanding of the equipment installed in each of their properties as well as managing empty properties. They are also wanting to take a bigger role in supporting their tenants (with their consent) in managing their energy use. If provided with industry data, housing associations can provide targeted information to their tenants and help them make informed choices about their metering system, manage empty properties as well as understand the equipment within the properties they own.

Summary
The Third-Party Service Provider Non-Switching category is a new EES User Type for organisations providing services to generators or end-users for purposes other than Switching. One such organisation is a provider of a platform for Microgeneration Certification Scheme (MCS) installers to simplify the way in which renewable installation applications are submitted to Distribution Network Operators (DNOs). Access to MPANs will enable the installer to cross-reference with details provided by the customer to ensure accurate data it provided to the DNO for the connection of the generation system. It will also assist in identifying the correct meter point in conversion properties. The DNO application for the connection helps the customer receive an export MPAN and the confirmation of a smart meter and who the Supplier is supports a smooth customer journey in setting up export tariffs.

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
08/11/2024 - This Change Proposal has been implemented as part of the November 2024 REC Release.
Summary
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, grammatical or consistency errors, and provides an opportunity to introduce necessary clarifications. This change proposal is looking to fix an error identified with R0206 Cross code change to align with BSC CP1598. BSC CP1598 was raised to add six scenario variants to four Market Messages that have been identified as missing. The REC Energy Market Data Specification contains a number of Market Message scenario variants used in BSC processes. This REC Change Proposal has been raised to align with CP1598 and ensure these scenario variants are added to the REC Data Specification. The legal text for R0206 approved at Change Panel on 15 October 2024, had a change to one of the scenario variants (SV00474) that was not clear as it was not red lined. The change was to the owner of the scenario variant from the Retail Energy Code Company (RECCo) to the Balancing and Settlement Code Company (BSCCo). The red lining for SVcccc was also incorrect as it deleted RECCo as the owner when in fact it is a new scenario variant so no previous owner. The owner as BSCCo that was approved, is correct.

27/02/2025 - Change is now not being merged into any other changes and will proceed as a standalone change. A potential solution has been identified, but will be discussed for potential cross code impacts
Summary
Currently within Schedule 23 a Registration can only be undertaken on RMPs with an Operational or Dormant RMP Status, and not Terminated. Terminated is a status that the RMP is set to when the Meter Point Status is no longer operational or the site is isolated. It is right that these sites are not able to be Registered as there is a risk that Suppliers could inadvertently Register such Meter Points. We do have instances where such sites are stranded in defunct Supplier portfolios - and the Supplier no longer has the capability to take the relevant action to Deactivate the Registrations. This may because the operational staff have left and the business is in administration.

Proposal to Enable Broader Use of Retail Energy Location (REL) Data for Non-Switching Applications

Change Category
Change Path
Priority
Urgent
No
Latest Update
04/08/2026 - On 04 August 2026, the REC Change Panel approved the extension to plan for I0218. Service Provider Impact Assessments are in progress.
Summary
The problem being addressed is the current restriction within the Retail Energy Code (REC) that limits the use of Retail Energy Location (REL) data solely to switching purposes. This restriction prevents the full utilisation of REL data, which could be valuable for a broader range of operational, regulatory, and industry applications. Key Issues: - Currently, REL data, enriched with Unique Property Reference Numbers (UPRNs), is available via the Electricity and Gas Enquiry Services. However, Schedule 29 (Address Management) of the REC restricts its use to switching purposes only, preventing its use in other important industry initiatives. - Various industry stakeholders, including REC and non-REC data requestors as well as Ofgem (the regulator), have expressed a strong interest in utilising REL data for non-switching purposes. The restriction is seen as a limitation, especially for initiatives that require accurate property data to support wider operational and regulatory functions. - By restricting the use of REL data to switching, stakeholders are unable to fully leverage it for improving operational efficiency, regulatory compliance, and overall service delivery. Lifting this restriction would enable the wider use of REL data, allowing stakeholders to benefit from its full potential across various non-switching applications.

Proposed solution summary
- RECCo would acquire a AddressBase Core license from Ordinance Survey and the REC would be updated to allow parties to take full advantage of this data. In order for parties to use the REL data, they would need to acquire an AddressBase Premium license from Ordinance Survey or other relevant license.
Problem Statement
Retail Energy Location (REL) data currently is not permitted for uses such as improving customer service and streamlining internal processes. This means that stakeholders, such as Ofgem and data requestors, have been unable to benefit from this data and Consumers are therefore unable to benefit from the full potential use of their data.
