Gas shippers – convey gas in the pipeline network by contracting with gas transporters, such as National Grid. Gas shippers must have a Gas shippers licence before taking part in any gas shipping actions.
Gas transporters – own and operate the gas distribution network, using the infrastructure to transport the gas from producer to end consumer. Transporters may take responsibility for quality testing and gas metering.
Suppliers – are responsible for customer interaction and provide an interface for consumers to purchase their gas. Suppliers must have a Gas retailer licence before engaging in any consumer contracts.
Customers – purchase gas for residential, commercial or industrial use. They contract directly with gas suppliers to secure their gas.
