Billing standards

Back billing is when a supplier sends you a bill to account for mistakes that have been made in calculating historic bills. For example, if there is an error with your unit rate we would correct this and send you a bill for the difference between what you paid and what you should have paid.

We realise how much strain back billing can put on small businesses so Gazprom Energy has signed up to a set of voluntary back billing standards for micro business customers.
Both Gazprom Energy and our micro business customers have responsibilities when it comes to billing. You can read more about your responsibilities in the voluntary back billing standards document.

Our commitments include:

We’ll adhere to the supplier responsibilities included in the voluntary standards document.

  • When micro business customers fulfill their responsibilities, we’ll limit back billing to 3 years for electricity and 4 years for gas which is a significant reduction on the standard six years set by UK legislation.
  • Upon discovering that a micro business customer has been incorrectly billed for their energy consumption, we’ll get in touch as quickly as possible. We’ll correct the billing rates and where appropriate and possible we’ll contact the customer before issuing a back bill. 
  • We’ll treat customers fairly when it’s necessary to issue a back bill by taking into the account the age of the bill, the length of the contract, the customer’s payment history and the circumstances that resulted in the back bill when setting repayment terms.

Gazprom Energy is happy to answer any queries you have on our micro business back billing commitments.
