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.

Latest Update
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.

Latest Update
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.

Problem Statement
Suppliers who do not operate, or intend to operate, in the Smart or Unmetered Market Segments, will be seeking exemptions from the relevant MHHS Qualification requirements. At present, there is no mechanism in CSS to prevent Suppliers from registering Metering Points for which an exemption has been granted and for which they are therefore not qualified.

Problem Statement
There is no time scale by which Energy Suppliers need to have submitted the Registration De-Activation Request or for electricity to have raised a query with the Distribution Network Operator (DNO) if they believe the Metering Point should not be Disconnected. This raises difficulties for the REC Performance Assurance team when monitoring and enforcing this obligation.

This Change Proposal has been implemented as part of the February 2026 REC Release.
Summary
The drafting in Schedule 28 – Related Metering Points has been updated for Market-wide Half Hourly Settlement (MHHS), allowing related Metering Points to be in a Status of Operational or Created in MPRS, as long as all Related Metering Points are in the same Status. This Change Proposal suggests allowing Secondary Metering Points with a Status of Created to be linked to Primary Metering Points with a Status of Operational, for MHHS migrated Metering Points only.

Problem Statement
By not allowing Primary Metering Points with a Status of Operational to be linked to Secondary Metering Points with a Status of Created, where the Metering Points have migrated into the MHHS arrangements, full advantage is not being taken of the MHHS functionality of automatically appointing agents to Secondary Metering Points.
