The Times reported that energy broker Catalyst Consumer Services has estimated if they happen, the price rises may take average annual household energy bills past the £1,000 mark.
Discussing the possibility of price rises with the newspaper, the home services head of uSwitch.com, Tim Wolfenden, said: "The bottom line is, if one supplier is feeling the pressure it will pass it on to the consumer. The floodgates will open."
Mr Wolfenden also gave his verdict on that issue, stating that the disappointment of rising prices may hit consumers harder next year.
