Summary
The current solution for Erroneous Switch (ES) resolution is failing some Consumers, there are gaps in the process and several areas that could be considered for improvement. It has been a number of years since the process has been reviewed end to end. Since then, Faster Switching has been introduced and MHHS is on the horizon.

Problem Statement
There are many Parties who have acceded to the REC but not Qualified within 12 months of accession, and who have not contacted the Code Manager within 6 months. This may cause confusion for Parties in knowing which other organisations have Qualified for roles under the REC.

01/07/2025 - On 01 July 2025, the REC Change Panel voted to reject R0235 and approve R0235A, in line with the Code Manager's recommendation. The appeal window has closed.
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.

Latest Update
This Change Proposal has been implemented as part of the REC Release on 27 June 2025.
Summary
Energy theft is a significant issue, costing consumers between £457 million and £760 million annually (based on Autumn 2024 retail prices). Energy theft also poses safety risks, particularly due to tampered meters, which have caused fatal incidents. Whilst existing measures under the REC, such as the Energy Theft Tip-Off Service (ETTOS) and Theft Detection Incentive Scheme (TDIS) seek to provide information on likely instances of energy theft and the incentives to investigate them, there are currently insufficient enforcement mechanisms and coordination with law enforcement agencies. In particular, there are challenges due to limited police engagement and inconsistent prosecutions, contributing to a low deterrent.

Problem Statement
The introduction of the ETU provides the mechanism to prosecute and add a significant deterrent previously missing from the theft landscape. To ensure an effective operation of this unit, the referrals should include standardised data by introducing the Referral Assessment Service (RAS). RAS will assess, triage and co-ordinate theft referrals received from industry parties.

Problem Statement
Whilst existing measures under the REC, such as the Energy Theft Tip-Off Service (ETTOS) and Theft Detection Incentive Scheme (TDIS) seek to provide information on likely instances of Energy Theft and the incentives to investigate them, there are currently insufficient enforcement mechanisms and coordination with law enforcement agencies. Energy theft is an illegal activity where criminal charges are being given if perpetrators are being prosecuted. However, these are rarely happening due to limited police engagement and inconsistent prosecutions. This means offenders may re-offend given the low deterrent.

Latest Update
This Change Proposal was implemented as part of the 7 November 2025 REC Release.
Summary
This Issue has been raised to develop the dedicated Non-Domestic Change of Occupier SDEP screens that were not possible as part of R0155 – Change of Occupier: Evidentiary Standards and Timescales. Should this Issue progress with a developed solution, the new dedicated Non-Domestic Change of Occupier screens would replace the temporary work around provided as a temporary workaround in the R0155 solution.

Solution Development
Proposed solution summary
- The solution will be developed through the Change Issues Group. Attendees will be invited to discuss and determine the requirements for the dedicated Non-Domestic Change of Occupier SDEP screens (a separate screen will be required for both Gas and Electricity). The solution will also require reporting for Performance Assurance and will include a plan for queries raised at cut over and data retention obligations. To help drive those discussions a starting point could be as follows: • Meter Point X Number (MPxN) • Multi MPxN flag – i.e. are there more than one • Date of CoO • Number of attachments • Accept evidence - Y / N – only available to the receiving supplier • Additional info – must be populated if N Auto populate: • Date of creation, date of response. • The Service Level Agreement (SLA) is 10 Working Days so it will need the RAG status based on that. Escalations screens – as per the standard REC escalations – including MPxN, date of creation and number of attachments. As part of any solution, the Code Manager will also update the non-mandatory Non-Domestic Change of Occupier Guidance Document to include further details on the newly dedicated SDEP screens, as well as further training material for Energy Suppliers.
Problem Statement
Due to the MHHS Code Freeze, newly dedicated Non-Domestic Change of Occupier SDEP screens could not be implemented as part of the R0155 solution and instead the use of re-purposed, existing screens was proposed as a temporary workaround. Energy Suppliers were clear in their responses to the R0155 impact assessment and consultation that using a temporary work around (with the temporary solution being the use of existing screens PT0056 and PT0067) would create additional workload and risk and that newly dedicated SDEP screens for Non-Domestic Change of Occupiers would still be required.
