Data Transfer Service (DTS)



What is the DTS?

The DTS underpins the competitive UK electricity, gas, and water markets, enabling participants to work together to exchange information about their customers. The DTS provides a managed file transfer service that allows market participants to share data efficiently and securely to perform their roles in the market. 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).

The Data Transfer Network (DTN) is the underlying architecture which underpins the regulated data exchange for the energy industry defined across several industry codes (currently the REC and BSC) and between bilateral parties. Data is transferred using industry-created data flows generated on FlowBuilder. Under the governance of the industry, outlined in the DTS Agreement, ElectraLink operates the DTS for the industry on a cost-recovery basis.

Over 99% of all DTS data is transferred within five minutes. There are multiple ways that you can transfer data using the DTS and a variety of formats in which you can receive information.
