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.

Latest Update
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.

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.

Problem Statement
This is a Housekeeping Change Proposal subject to the Housekeeping Change Proposal process, rather than the standard change process. The nature of the change is that it makes non-material changes to the REC Products to correct typographical and consistency errors. It also provides an opportunity to introduce necessary clarifications.

Summary
Prior to R0118 - Review of Schedule 12 and processes to manage access to data being approved, the Code Manager accepted Change Proposal R0056 - EES/GES Additional Service Request for Housing Associations to be added to the Data Access Matrix from Corella. Corella’s intention was to create an API specifically to provide a range of Data Items to Housing Associations, having worked closely with a Housing Association to create a prototype API which provided benefits to them. The Code Manager has considered the broad list of Gas Data Items originally requested and is proposing to provide access to only a subset of these, to enable the Housing Association to identify where a live gas supply exists at the property to comply with the Gas Safety (Installation and Use) Regulations. Once the API is delivered, the Code Manager expects other Housing Associations to make use of it, as an alternative option to the standard Housing Association Report that exists today however has more limited data.

Summary
Following the implementation of MHHS, there is a requirement to host a selection of ISD information acquired from the Market Domain Data Tables (currently hosted by Elexon), centrally within the REC Data Specification. The existing data tables are as follows. MDD Entity ID 27 – Clock Interval (c.11,000 records) MDD Entity ID 29 – Measurement Requirement (c.1500 records) MDD Entity ID 32 – Standard Settlement Configuration (c.1000 records) MDD Entity ID 38 – Time Pattern Regime (c.1200 records) Given the volume of data contained within these tables, the simplest solution is to host and provide this information to REC parties, via Spreadsheet (CSV format) on the existing RTS platform, Digital Navigator/EMAR. We would like to consult parties for their view on presenting the data in this format. There are other formatting options we could consider, including the provision of this information in more than one format. Option 1 – CSV only Option 2 – SQL only Option 3 – SQL and CSV This new Category 3 document will also be added to the REC Baseline Statement.
