23/06/2026 - The Code Manager has published an Interim Guidance Document for I0273.
Summary
In the MHHS design the Standard Settlement Configuration (SSC) is a non-mandatory data item for Smart and Advanced metering points, in addition the register level TPR information is not shared in the MTD flows for these meters (IF-006 for Smart and D0268 for Advanced). It was identified through BSC Issue I118 that there is a requirement for the SSC to be set for Domestic / Microbusiness Advanced Metering Points making use of the HH data opt out and there may be other areas where the SSC is required.

This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
REC Schedules 1, 14, and 15 all note that in order to Qualify as a Safe Isolation Provider (SIP), the Party needs to be a Qualified Meter Operator Agent (MOA). It has since been determined that Qualified Electricity Metering Operatives (EMOs) should also be able to Qualify as SIPs.

Problem Statement
Requiring SIPs to be fully Qualified MOAs may be hindering smaller Parties who wish to be SIPs from Qualifying under the REC. This in turn may be reducing the number of Qualified SIPs in the market for Consumers to choose from or causing Consumers inadvertently to contract with people who are not Qualified SIPs to carry out SIP Works.

Latest Update
This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
Within MHHS SIT there is a scenario where the LDSO generates a D0139 to the MS for a PPM but the requirement is for the MS to generate a D0179. There is a gap in the D0179 data required and that provided on the D0139. 21.5.1 & 21.5.6 under Schedule 14 states that where the DNO changes the energisation status, within 3 WD of changing the energisation status the DNO will send the D0139 or the D0179(21.5.6) to the MS and then the MS will generate the D0179 to the Supplier(21.5.6). Currently, the LDSO only generates the D0179 to the Supplier but not to the MOP and the only change under MHHS is to add the new variant MSS.

Problem Statement
DNOs and MOAs cannot fulfil their full obligations listed in Schedule 14 Metering Operations as there missing Scenario Variants in the Data Specification preventing them from sending the D0179 to all required Parties. This alternate solution proposes the removal of the D0179 from the legal text and the D0139 to be used in all scenarios.

Latest Update
12/08/2026 - the Proposer has chosen to withdraw this Issue as MHHS means many of the effective dates are being updated as per the original business case so the change is no longer required.
Summary
On a switch many of the effective dates within EES default to the switch date. This includes energisation status. It means EES users that don't have access to the meter technical details do not know the actual date the status changed.
