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.

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.

02/06/2026 - the REC Change Panel voted to reject the implementation of this Change Proposal, in line with the Code Manager recommendation. The appeal window closed on 17 June 2026.
Summary
MHHS removes certain Data Items (e.g. Profile Class, Measurement Class, Standard Settlement Configuration, Time Pattern Regime etc.) that are important to wider processes and products offered to consumers. This proposal is seeking a mechanism for electricity Market Participants to look up the previous entries for these legacy Data Items held before MHHS Migration begins.

Problem Statement
The risk of loss of certain Data Items for MHHS Migrated Metering Points may impact Parties in their ability to carry out and support industry processes, or in what products they are able to offer Consumers, in both the MHHS Market and following a Reverse Migration.

Latest Update
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.

Latest Update
08/08/2024 - the Proposer has withdrawn this Change Proposal.
Summary
RECCo is tasked with fulfilling several obligations. This proposal has been raised to amend some of the wording within the REC, which would benefit from reassessment. When the REC was originally drafted, references to RECCo in the code were originally intended to refer to the activities directly managed and overseen by the REC Board, and were considered separately to activities managed by the Code Manager.
