Data Transfer Service

Welcome to ElectraLink’s Data Transfer Service (DTS) page. If you’re thinking of becoming a user or just want to understand what the DTS is, you can find an overview of the service here. If you would like to understand the steps to get started please follow this link.

What is the DTS?

The DTS is the regulated service that underpins the UK competitive electricity industry and enables market competition. From 2016 we will also provide regulated services in the gas industry. In the deregulated market, market participants are required to work together in order to exchange information about domestic customers. This information interchange uses a common set of industry requirements to facilitate business-critical processes, such as settlement, change of supplier and metering, which are implemented through a centralised communications service: the DTS. This is owned and maintained by ElectraLink.

New Technology

The DTS has recently undergone a major technology transformation programme in order to allow existing and new customers to access to the market via the latest technology. In line with these new changes the DTS now has the capability to transmit electricity industry data flows in an XML format.


XML is a modern and common method of exchanging information that is readable by both machines and humans. Because many of the applications in use today use XML as standard, the introduction of an XML capability within the DTS will potentially enable parties to streamline internal processes by removing the need of translating XML files into the industry standard formats prior to transmitting over the DTS.

Please note that Users of the DTS will continue to be able to send and receive files in their preferred format including legacy industry standard formats and the service will convert the file formats where required. Translation to XML can be set up via configuration software provided as part of users’ connections to the DTS.

An high level XML File Design Specification document is available from the downloads section of our website here (please login to access or register with the ElectraLink website by following the Register link at the top right of this page). The document describes how Users should structure the XML Files which are to be transferred between Users applications and the Data Transfer Network (DTN) Gateway. When used in conjunction with the current version of the Data Transfer Catalogue (DTC),

It also describes the principles, structure and syntactic rules for constructing XML Files. The document is generic, i.e. not specific to any particular data flow and is intended to apply to all Users of the DTS. The document should be used in conjunction with the DTC (versions 3 and beyond), where the logical content of individual data flows is specified. The document also contains links to XML schemas.

If you are interested in learning more about the use of XML over the DTN please send an email to or call us on 020 7432 3012.

DTS Governance and Change Management

The DTS is governed by the DTS User Group which is constituted of elected members. The DTS User Group meets on a quarterly basis to review service performance, submitted change requests and to represent the interests of DTS users. The scope of the service is defined within the Data Transfer Services Agreement (DTSA), a multi-party agreement to which users of the service accede. You can download a copy of the current DTSA from here.

If you are an existing user of the DTS and would like to know who your DTS User Group representative is, you can find out in the password protected part of the site here.

Users of the DTS can raise changes requests to ElectraLink regarding the DTSA, the Data Transfer Handbook, or the DTS itself at any time. ElectraLink will, in line with the change control process outlined in clause 7 of the DTSA impact the requested change and make a recommendation to the DTS User Group at the next available opportunity.

A change request form is available here in the password protected area of the website.
