Problem Statement
There is a potential for Consumer detriment under the Market-wide Half Hourly Settlement arrangements where a customer unknowingly selects a tariff (i.e. single rate) where they have an Economy 7 type configuration on a Smart meter for water/storage heating. A solution is required that enables a Supplier to identify a Smart E7 Consumer during the Switch process to ensure they can offer the correct tariff and prevent consumer detriment.

Latest Update
28/04/2026 RECCo are currently conducting solution development activities on this REC Issue as part of their dual-fuel Enquiry Services project. Further updates to be expected upon progression of the project.
Summary
As part of RECCo’s plan to procure a dual-fuel Enquiry Service, there will be a single point of entry to API services. A migration plan has been developed with two independent stages. For stage one, all current Enquiry Service API users will need to connect through RECCo’s API Gateway rather than connecting directly to the existing EES and GES APIs. This will require users to amend the URLs they call when accessing the services.

An Update to Plan has been approved by the REC Technical Expert Panel on 25 June 2026.
Summary
The Meter Manufacturers Make and Type (J0410 / DI-048) was not populated as part of the MHHS Programme's data cleanse. However it is part of the SMRS maintained Meter Technical Details (MTDs) for Smart Meters which replace the DTC MTD Market Messages for Smart Meters in the MHHS environment. It is not currently possible to populate this item in the legacy arrangements.

Problem Statement
Following MHHS Migration, the MTDs provided by SMRS do not include the Meter Manufacturers Make and Type, as this replaces the existing D0149/D0150 Market Messages it could lead to the information being lost. This will mean Energy Suppliers and MOAs will not know the make and type of meter installed at a particular Site.

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.

This Change Proposal has been implemented as part of the June 2026 REC Release.
Summary
During the quality checks of REC Schedules for MHHS, several capitalised terms throughout schedules were identified with no entry in Schedule 1. It has also been identified that there are definitions that link to Schedules (such as 2, 20 and 21) which are no longer live REC Schedules. The Code Manager has reviewed these and determined some changes are required to Schedule 1.

Clarification and Amendments to Annulment Definition in Schedule 23 – Alignment with SLC Obligations

Change
ID
R0287
Change Category
Priority
Urgent
No
Latest Update
This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
The current wording of the Annulment definition in REC Schedule 23 – Registration Services does not sufficiently align with the obligations set out in Ofgem’s Electricity Supply Standard Licence Conditions (SLC) 14.2(d),14.4(c) and 14.10. This misalignment has led to inconsistent interpretations of the usage of the Annulment process across the industry compared to the intention of the REC change and the licence obligation. This Issue is seeking further amendments to REC Schedule 23 - Registration Services and clearer guidance. This clarification is essential to prevent retention-based misuse, ensure regulatory compliance, and uphold Consumer trust in the Switching process.

Summary
The first complex technical change R0067 (Introduction of CSS Refresh Functionality) encountered a number of challenges within the design and implementation process, the change was scheduled for implementation on the 6th December 2023, however, the change was deployed with defects and was not fully operational until February 2024. Following that session, the Code Manager held discussions, and a formal Lessons Learned session with all Service Providers and identified a number of challenges with the technical change process. Some of these challenges can be attributed to the timing of the detailed design, Detailed Impact Assessments (DIA) and party impact assessments
