Problem Statement
A linkage error has been identified as part of BSC CP1622 and REC Change Proposal R0300 where the DIP Data Item DI-091 has been incorrectly linked to the existing J0478 ‘Number of Register Digits’ in the EMDS at MHHS Go-Live, instead of the existing J2313 ‘Number of Displayed Register Digits’. As a result, contrary to the MHHS design and intended linkage, the EMDS incorrectly details the DI-091 in DIP interfaces, including the IF-005 and IF-006 (both REC-owned) and several other DIP Interfaces, even though the DIP reference appears correct (DI-091). It is important that EMDS is an accurate reflection of Market Messages and Data Items. Without correction this Issue may cause issues to future market entrants.

Summary
Elexon have raised CP1622 to amend the Validation rules within the Supplier Meter Registration Service (SMRS) for the Number of Register Digits Data Item within the IF-005 Market Message, to allow digit values from 1–9, ensuring accurate data and reducing exceptions. There are no Validation rules related to the D0312 Market Message which need to be amended under the Balancing and Settlement Code (BSC), but the D0312 itself contains a Data Item Rule regarding the Number of Displayed Register Digits which needs to be amended in line with CP1622.

Summary
R0277 – Data Latency SLA alignment for Gas Enquiry Service amended two performance levels within the Gas Enquiry Service (GES) Service Definition. However, these changes only addressed ambiguity on when the performance level applied from and to and increased the number of hours in which data will be available to Authorised Persons within the Supply Point Switching API. This change will seek to support the changes made under R0277 whilst also providing a suitable percentage SLA target for the Gas Enquiry Service Provider to meet these measures.

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.

Latest Update
07/07/2026 - The Change Report (Update to Plan) has been approved by the REC Change Panel. This Update to Plan reset the Priority Category and urgency status of R0294, following the deferred implementation of the lead BSC CP 1607. R0294 continues to be on hold until further solution development is undertaken as part of CP 1607. The Code Manager will continue to work with Elexon and Service Providers for future progression of any changes to implement the IF-051.
Summary
The IF-051 provides a refresh of data from Supplier Meter Registration Service (SMRS) to the Electricity Enquiry Service (EES) (REC) and Market Data Service (BSC). Currently the REC does not hold any detail regarding the DIP Market Messages that the EES is required to receive and process. Due to the nature of the IF-051, the EES Provider obligations need to be clear to ensure the interface can be received and processed appropriately.

Problem Statement
BSC CP 1607 will implement a new DIP Market Message, the IF-051 ‘Data Refresh’ on 26 March 2026. EES will be a recipient of that change. If EES is not able to receive and process instances of the IF-051, data in EES will be misaligned with other industry systems (SMRS, DIP and MDS) meaning that it will not maintain its role as the accurate reference point for industry participants. This could lead to potential disruption of industry processes.

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.
