Household energy bills could rise every three months instead of six under new plans to review the price cap that limits what companies can charge consumers.
Ofgem, the energy regulator, said it might insert two extra reviews a year, one in January and another in July.
Ofgem chief executive Jonathan Brearley has said that proposed changes to review the energy price cap four times a year would mean that bills could go up quicker, but they will also fall more rapidly.
