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.

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.

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.
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.
