Representatives of some of the UK's biggest energy suppliers, including Octopus Energy, EDF and E.On, gave a bleak assessment about the future of energy bills at a parliamentary hearing yesterday (Wednesday 15th October 2025) - with bills predicted to rise on the back of future grid upgrades.

Chris Norbury, chief executive of E.ON UK, said “If I look at the non-commodity costs, policy costs, network costs, then certainly some of the modeling that we have suggests that you could get to a position by 2030 where if the wholesale price was zero, bills would still be the same as they are today because of the increase in those non-commodity costs.”

Non-commodity costs include everything from government levies to taxes - basically everything other than the actual cost of the energy.

“If we continue on the path that we’re on right now, in all likelihood electricity prices for a typical customer are going to be 20% higher in four or five years’ time than they are now,” said Rachel Fletcher, director for regulation and economics at Octopus Energy. “And that’s even if wholesale prices halve.”

What was said at the parliamentary hearing undermines the government's assertion about the UK's effort to nearly eliminate emissions from its power grid by 2030, which would also lead to lower bills for consumers.
