Latest Update
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.

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

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.

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.
