    This form relates to UNC Modification 0788 (urgent), which was implemented on 1 November 2021.

    The Modification applies to Suppliers who are operating under a ‘Deed of Undertaking’ pursuant to Condition 18 of the Supplier Licence.

    Following the termination of their Shipper, this Modification enables Suppliers to utilise other Shipper relationships to source additional supplies of gas.

    This can now be done under the updated ‘Deed of Undertaking’ until a new registered Shipper is in place.

    You can find out more details in the UNC 0788 (Urgent) Final Modification Report.
