£12 energy bills rise: A breakdown of the figures

Under Ofcom's revised proposals, household energy bills will rise an average of £12 per year between 2013 and 2021.

The amount is not cumulative as investment and costs "vary year-on-year".

Ofgem said energy bills are expected to rise from today's prices in the following manner:

  • 2013/14 - £8.50
  • 2014/15 - £7.30
  • 2015/16 - £11.20
  • 2016/17 - £11.60
  • 2017/18 - £13.30
  • 2018/19 - £14.50
  • 2019/20 - £14.20
  • 2020/21 - £15.10

The energy regulator said half the total average bill - £6.20 - is related to tax changes affecting the gas distribution network companies "that are outside Ofgem's control".
