Summary
The Balancing and Settlement Code (BSC) modification P441 is looking to introduce Complex Site classes which would categorise the types of Complex Site with each having clearly defined criteria within the BSC whilst also facilitating a new "type" of Complex Site (referred to as a Class 6 Complex Site) to allow approval of "non-standard" Complex Sites. It will also clarify when the netting of Imports from Exports for multiple Metering Systems registered in Supplier Volume Allocation (SVA) is permitted.

Problem Statement
The annual portfolio reconciliation exercise conducted by the CDSP on MAM-held Data Items is neither frequent enough nor is it expeditious enough, according to the Proposer. MAMs are being asked to reconcile Data Items several months after they were initially provided, which may impact the efficacy of the exercise if these Data Items have changes since they were initially submitted.

Ofgem's decision can be found here: https://www.ofgem.gov.uk/publications/r0207-retail-energy-code-rec-proposed-changes
Summary
BSC Mod 459 and REC CP R0144 were raised to allow different MOAs to be appointed for the import and export MPANs on a shared meter. One of the justifications for this was to stop export suppliers being charged inflated rates. Both changes have been placed on hold due to the MHHS Programme so this change has been raised to specifically resolve the charging issue.

Problem Statement
Where the same electricity Metering Asset is being used for the measurement of Import and Export for more than one Metering Point, the Export MOA must be the same as the Import MOA. This may result in uncompetitive charging by the MOA, as the Export Supplier has no choice in their appointment.

Problem Statement
Work conducted by RPA has identified a significant number of mismatches between gas Data Items held by key stakeholders. This may result in Consumer detriment, as information relevant to an MPRN may not be held accurately by any given Party. As such, there is a need to review processes pertaining to the communication of gas data by MAMs onward to the CDSP to mitigate the potential for mismatches.

10/06/2026 - The Code Manager, following an approval to an Update to Plan by the REC Metering Expert Panel, has placed I0197 on hold.
Summary
Some customers have had faulty meters for a prolonged period, which impacts billing and settlement, and can prevent customers accessing specific tariffs. Currently the REC only has obligations relating to electricity meter faults, and these do not actually require work to be done to address faults. This issues proposes the introduction a maximum timeframe Fault Resolution deadline to resolve issues around faulty meters.

This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
Studies conducted by the REC Performance Assurance (RPA) function of the REC Code Manager have concluded that gas market data fidelity may be improved by reducing the frequency of missed messages between Metering Asset Managers and other REC Parties. This Issue seeks to explore mechanisms by which a reduction in the number of permissible communication methods used by MAMs could support the data quality improvement objective.

Problem Statement
MAMs communicate with each other, and with other parties, using up to three possible methods as they send Market Messages in line with their obligations in the REC. It has been suggested that moving to a single communication method might help mitigate gas data quality issues. This Issue seeks to explore an interim solution to facilitate this.
