Energy: Billing

The question

To ask the Secretary of State for Energy Security and Net Zero, whether he has made an assessment of the potential impact of energy suppliers holding large aggregate customer credit balances on household finances.

Answered by Martin McCluskey

The level of customer credit balances held by energy suppliers is a matter for Ofgem, as the independent regulator.

Energy suppliers use credit balances as a way to smooth customer direct debit payments over a year, accounting for seasonal variations in usage. If a customer has concerns about their direct debit or the level of credit balance they should contact their energy supplier.

Under the terms of Ofgem’s Standard Licence Conditions, customers may challenge increased direct debit payment amounts with their supplier and ask the supplier to justify how amounts have been calculated. Suppliers must explain clearly how they reached the figure they want to charge and give the meter readings used.

Customers can ask their supplier to lower monthly direct debit payments to reflect the energy use more accurately and if a customer is concerned about the size of a credit balance on their energy account, they can ask their supplier to refund it.
