Energy bills for a typical household could hit £4,266 next year, consultancy Cornwall Insight has warned.
The higher estimate means the average household would be paying £355 a month, instead of £164 a month currently.
The energy bill warning comes as the government rejected calls for further help on energy bills until a new prime minister is in place. The CBI business lobby group said it "made no sense to wait" for a new Conservative party leader.
