Accessing our secure documents

Many of our documents contain commercially sensitive data, which is why they are hosted on our secure internal network or intranet (SharePoint).

For users outside Xoserve to view these documents, we have created an extranet, enabling secure access to external authorised users.

Who can apply for access?

Access to our secured documents is available to:

  • Network Operators (Gas Transporters (GTs) and Independent Gas Transporters (IGTs))
  • Shippers

Access can also be provided for third parties who are referred by either a Network Operator or a Shipper.
