Who We Work With

Xoserve works at the heart of Great Britain's gas industry.

Data Services Contract

The Data Services Contract (DSC) is an agreement between our customers, Great Britain's Gas Transporters, Independent Gas Transporters (IGTs) and Shippers for the services that we deliver as the Central Data Service Provider (CDSP).

They all share responsibility for decision-making about services provided under the DSC, and for our funding so that it can carry out its service delivery and change programmes.

Signatories to the Uniform Network Code

Alongside the DSC, all gas transporters and shippers sign up to the Uniform Network Code (UNC).

The UNC is the hub of the competitive gas industry. It is a legal and contractual framework for gas supply and transportation.

Xoserve serves as the common service provider for gas transporters and shippers, as highlighted within the UNC and DSC, to which they are signatories.

The Uniform Network Code is available to view on the Joint Office of Gas Transporters website*.

Industry Bodies

We work closely with Ofgem and the Joint Office of Gas Transporters, who both ensure that the gas industry remains fair and competitive for all customers.


Ofgem regulates Britain's gas and electricity industries.*

It protects and advances consumer interests, by promoting competition where possible, and through regulation only where necessary.

The Joint Office of Gas Transporters

The Joint Office of Gas Transporters was created as part of the distribution network sales process in May 2005, and its governance requirements are available in their Arrangements Agreement*.

Its role is to efficiently govern the process that underpins the commercial gas industry on behalf of gas transporters.
