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.

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.

Summary
There is currently a gap in the understanding of the effectiveness of the retail systems and processes in delivering positive outcomes for Consumers. While Consumer surveys are conducted on certain areas to some aspects of Consumer satisfaction, it may be necessary to expand the evaluation methods used by the Code Manager to gain a more comprehensive understanding.

Latest Update
26/08/2025 - Update to Proposal Plan published. This will be presented to the REC Change Panel at their meeting on 02 September 2025.
Summary
Non dual-fuel Consumers who register upon the PSR, will have their PSR data flow across energy industry data flows to mean that all parties are aware of any PSR Needs Codes, allowing us all to provide equal access to our services and support. This will be achieved via the utilisation of existing processes and systems. Initially a pilot will take place for a minimum of 3 months between participating companies before extending this to the whole industry”.

Problem Statement
The majority of domestic customers in the UK are what are called in the industry ‘dual-fuel’ - this means that with two types of energy (electricity & gas) a domestic dwelling has a single supplier ie they pay their bill to one organisation. This ‘dual-fuel’ position has supported the industry improvements to Priority Services Register (PSR) data flows by allowing previous divides to be overstepped in terms of data flows between energy types. There is however a problem which this RECC request aims to resolve. That is, where a customer who has both fuel types, also has two suppliers and they want to register upon the PSR. This was always a ‘known’ gap shared with our regulator when the many improvements were implemented across the PSR and considered to be something that would be addressed at a later date. This ‘gap’ means that without the dual-fuel link, currently data flows do not complete across energy types via the supplier data flow triggers.

24/03/26 - Issue placed on hold pending development of Energy Theft Reduction White Paper
Summary
There is a current disincentive for a Supplier to pursue a particularly complex energy theft investigation where there is both little prospect of costs being recovered directly from the Consumer and those costs materially exceeding the Theft Detection Value under the TDIS.

Problem Statement
Reported inconsistencies in the application of elements of the entire new connections process result in poor Consumer outcomes. Whilst the new connections process spans multiple processes owned by different Codes, the REC Code Manager is conducting an exploratory initial analysis, owing to our place as a dual-fuel, Consumer facing Code. This analysis is expected to yield multiple modifications across multiple Codes that will result in improvements to the new connections process.
