Welcome to electronic invoicing for Centrica

Centrica has successfully implemented an e-Invoicing project, which will enable our suppliers to submit invoices to us electronically. This improves the efficiency of our processing enabling us to better ensure we pay all of our suppliers on time. We aim to fully adopt e-Invoicing and will be phasing out acceptance of paper invoices.


E-invoicing provides mutual benefits, allowing you as a supplier to reduce your processing and distribution costs. You will be able to identify and resolve any queries promptly as well as view payment status online. e-Invoicing also helps fulfill our commitment to the environment, we estimate that this initiative will reduce annual paper usage equating to 260 trees.

To support your move to e-Invoicing and to manage the process going forward, Centrica has partnered with Tungsten Network. Tungsten Network offers flexible options for submitting e-invoices that accommodate a wide variety of supplier sizes, systems, and processing needs.

Suppliers do not need to install any hardware or software or change the way their systems are configured.

With no hardware or software to install, subscribing to the network is simple and suppliers can be sending invoices electronically within a short period of time after sign-up. Crucially, the Tungsten Network satisfies the demands of VAT/TAX administrations across Europe and North America who have accepted the removal of the need for a hard copy invoice for companies using the Tungsten Network service.
