Data Transfer Service

The DTS underpins the competitive UK Electricity, Gas and Water markets, enabling participants to work together to exchange information about their customers. This information interchange facilitates a wide range of business-critical processes including change of supplier, metering and how energy is paid for by suppliers (settlement).


FlowBuilder helps you design, amend, test and share message templates that can be loaded onto the DTS. This allows energy market participants to swiftly upgrade and test their systems in time for catalogue changes and new industry requirements, and to facilitate information sharing in bi-lateral arrangements.


RGMAConnect supports Gas and Dual Fuel suppliers and commercial metering agents to create and send RGMA flows, as well as providing an RGMA Data Flow Catalogue.
