    An overview of invoicing

    We provide essential billing and invoicing services across the industry.

    We’re responsible for:

    • transportation billing on behalf of Network Operators
    • energy balancing invoicing on behalf of National Gas Transmission

    We ensure Shippers and Traders who use the Transporter’s networks are charged correctly.

    Uniform Network Code (UNC) Charging Statements

    These charges are in accordance with the Uniform Network Code (UNC) NWO Charging Statements which are published on the Joint Office of Gas Transporters website.

    The billing and invoicing services we provide

    Gas is transported through the National Transmission System (NTS) and Local Distribution Zone (LDZ) network to the supply meter point.

    There are charges which relate to the different aspects of the supply and delivery of gas. We send all transportation invoices through the IX network as a generic invoice file (.INV).

    There are three transportation invoice categories:

    • Core invoices: the three core invoices are LDZ Capacity, Commodity and Amendments

    • Scheduled ancillary invoices: ad-hoc invoices that are issued on specific days, eg Meter Asset, DNI, Compression or Failure to Supply Gas

    • Unscheduled ancillary invoices: ad-hoc invoices issued on request, eg Request to Bill or Site Visit

    Energy balancing is the process of maintaining the balance between the gas that flows in and out of the system.

    National Gas Transmission is responsible for the safety and security of the system.

    Users have a financial responsibility to balance the gas they’re responsible for in the system and they’re incentivised to help them achieve this.

    We use Gemini to calculate the energy that enters and leaves the system.

     

    Plan ahead with our 2024 Billing Calendar

    Use our billing calendar to plan your payments for our services.

    It contains issue and payment due dates for individual invoices each month.

    Our 2024 Billing Calendar is now available in three formats: PDF, iCal and CSV

    Using the new CSV file, you can now load the key billing dates directly into your own systems. This will remove the need for manually converting the data into a suitable format.

    Request a copy of your Charging Schedule 

    In mid-February we issue you with a Charging Schedule, which provides a detailed breakdown of the charges we expect to be invoicing your organisation each month. 

    To request a copy of our Charging Schedule, please raise a support request. 

     

     

    VAT eligibility

    Most charges are VAT applicable, some are VAT exempt and others have VAT applied at 0%.  

    As a general rule, the prevailing VAT rate is charged for Transportation Charges (TPN) and at 0% for Energy Charges (ENG). 

    While the charges are VAT applicable, some Shippers are not registered in the UK and therefore will pay the relevant taxes in their country of registration.
