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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment he has made of the change in level of the network cost component of household energy bills in each year since 2010.

The table below outlines the network cost component of the average dual fuel bill from 2013 to 2016. This is the longest period for which there is comparable data for a dual fuel (gas and electricity) bill.

These data are published by Ofgem and based on realised costs as reported by the six largest energy companies in their annual Consolidated Segmental Statements, which can be found - https://www.ofgem.gov.uk/system/files/docs/2018/02/february-bills-prices-profits.pdf
