Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, if he will make an estimate of the average annual energy charges paid by (a) existing and (b) new customers in each of the last five years.

Average annual domestic bills for gas and electricity and industrial energy prices are published as part of the BEIS’s quarterly energy prices publication. The latest available figures are for the average annual domestic bills in 2015 which are £714 for gas (GB) and £584 (UK) for standard electricity.

The information required to distinguish between existing and new customers is not held by BEIS.
