Back billing guidance

We recognise that delayed invoices are frustrating and may result in payment difficulties. Under Ofgem’s revised supply licence, we limit the back billing of microbusiness customers to 12 months. However, this doesn’t apply if the customer has been obstructive or unreasonable. Please see our back-billing guidance below for more information.

Our policy further outlines how we can both prevent back bills occurring.

Back billing guidance

We’ve amended the terms of all existing SME Terms and Conditions – see below – to reflect Ofgem’s back billing requirements effective from 1 November 2018.
