User Administration Services (UAS) for New Customers

Join the GB Gas market and access services

User Administration for New Customers works through your admission to the gas market of Britain.

User Admission for new customers

The User Admission process is for customers who are entering the gas market of Britain. The process is for customers who are signed to the Data Services Contract (DSC) or UK Link User Agreement (UUA). Customers signed to these can collectively be known as Uniform Network Code (UNC) Users. 

For UNC Users, it is a five-step process, covering:

  • Validation
  • Confidentiality documentation
  • Accession documentation
  • Information Exchange (IX) arrangements
  • Accession to the UNC and DSC

New Shipper or Trader Customers (UNC User)

Downloadable documents outlining the User Admission process for Shipper or Trader customers on the gas networks are available:


Once you are ready to start, simply complete the New Customer Enquiry Form for a Shipper or Trader.

Contact the Customer Life Cycle Team if you need any further information.
