EDF Energy - one of the UK's big six energy suppliers - has called for a new approach to be introduced when pricing gas and electricity.
The French-owned supplier has revealed that it would be in favour of a single-unit pricing system, which it believes would make it easier for consumers to compare prices when they shop around - much like they do when currently buying petrol.
However, industry regulator Ofgem - which has its own plans in place to simplify the market as part of the Energy Bill - has argued that such a system would not be easy to introduce and implement. It's stated that the number of payment options, as well as special energy packages, would be the main barrier to adopting the system.
EDF has responded by stating that it believes Ofgem's proposed pricing system is too complicated.
It also reiterated that it would only be willing to implement a single-unit price system if other energy companies decided to take the same approach.
Executive director of consumer body, Which?, Richard Lloyd, has stated that a simplification of the energy pricing system would be beneficial to consumers.
He said: "When we've tested prices being presented in this simple way we've found eight in 10 consumers can readily spot the best price for them.
"So the current system is too complicated, the regulator and the government want to simplify the energy market for consumers, and the reforms they're proposing at the moment are still too complex," Mr Lloyd concluded.
British Gas - one of a number of suppliers involved with government's Green Deal initiative - has rejected Ofgem's proposal.
However, rather than having to pay the costs upfront, homeowners can pay the money back in installments added to their gas and electricity bills.
