Funding, Governance and Ownership

Xoserve is led by a board of Industry-nominated directors, with an independent Chair.

Our Funding, Governance and Ownership

We are funded, governed and owned by the gas industry, with our board made up of industry-nominated directors and chaired by an independent Chairman.

As the Central Data Service Provider (CDSP) for the gas industry, we have a Data Services Contract (DSC) with our customers who are licensed gas Shippers and Gas Transporters (GTs).

We also have a UK Link User Agreement (UUA) with customers including gas traders and meter service providers who need access to the UK Link service.

New shipper and transporter clients need to sign the DSC, while other companies including licensed gas shippers and traders are expected to sign the UUA.


The Xoserve board is chaired by Clare Spottiswoode.

Our Board members are:

  • Sarah Carroll, Network Director
  • Tina Sands , Network Director
  • Ian Radley, Transmission Director
  • Neil Shaw, Independent Gas Transporter Director
  • Colin Rees, Shipper Director
  • Mike Hogg, Shipper Director
  • Yehuda Cohen, Shipper Director
  • Duncan Sedgwick, Shipper Director

All signatories to the DSC share the decision-making for services provided under it. Decisions are made by three committees:

  • Contract Management Committee
  • Change Management Committee
  • Credit Management Committee

Committee meetings are chaired, organised and administered by the Joint Office of Gas Transporters. The Joint Office oversees the process for the appointment of voting representatives.


Xoserve invoices and collects funds from DSC and UUA customers in line with rules set out in the:

  • CDSP Budget
  • Charging Methodology
  • CDSP Credit Policy

CDSP Service Charges for 2019/20 reflect the Budget approved by the Xoserve Board in January 2019.

We are funded to carry out our service delivery activities and Change Programme by all DSC signatories.
