Proposed solution summary
- As a Consumer, where I have entered a bi-lateral NExA with the relevant Transporter, I want my Shipper and Transporter to have access to all the data they need when capacity referrals to the Gas Transporters are required.
- As a Gas Transporter, I want the details of the NExA to be held in GES, to increase visibility of the existence of the NExA and to provide details of the offtake parameters.
- As a Gas Shipper, I need to understand both that a NExA exists, and that I have visibility of the offtake parameters relative to the site, so that I can ensure that I take the necessary actions to ensure the Consumer has the appropriate booked Supply Point Capacity.

Changes to Supply Number Format for MHHS

ID
R0083
Change Category
Priority
Urgent
No
Latest Update
22/09/25 - This Change Proposal has been implemented as part of the MHHS M8 22 September 2025 REC Release.
Summary
The Electricity Supply License requires Suppliers to provide the Supply Number to each Consumer on every bill, or at least once per year where no bill has been sent. The Supply Number format is prescribed by the REC and is detailed in the Energy Market Data Specification. The MHHS design is changing the data associated with each individual metering point, including those data items currently displayed within the Supply Number top line. To support Electricity Supplier implementation of the MHHS arrangements, a clearly defined solution is required setting out a revised approach to populating the Supply Number on Consumer’s bills and statements.

Proposed solution summary
- As an electricity Consumer I want to be able to provide my prospective Energy Supplier with the necessary information for them to provide a suitable tariff. As a Non-Domestic Consumer, I want to have the necessary information that will allow me to access tariff information, specific to my business, to help me manage my energy. As an electricity Consumer, I want to have access to the data that will help me appoint my own Metering Equipment Manager (MEM) where permitted.
- As a Supplier, I want to know how to populate and format the Supply Number, so that I can meet my obligations to include it in Consumer bills or statements. As a Third Party Intermediary (TPI), I want Consumers to be able to provide me with the right information to provide appropriate quotes.
- As an independent Distribution Network Operator, I want to be able to identify and use the DUoS Tariff Id so that I can provide transparency on charging that is being applied to my customers. As the Electricity Enquiry Service (EES) Provider, I want to know how to populate the Supply Number so that I can make it available on the EES

Problem Statement
The Market-wide Half Hourly Settlement design is impacting the Data Items that are used in the top line of the Supply Number, which Energy Suppliers are obliged to provide to Consumers at least once a year under their Licence. A revised definition of the Supply Number format is required so that Electricity Suppliers have a clear understanding of the approach to populating the Supply Number for metering points that have migrated to the new MHHS arrangements.
