    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).

    To view these documents, we've created an extranet, enabling secure access to our intranet for 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.
