Energy bills could soar even higher as customers face forking out to run collapsed firm Bulb.
Business Secretary Kwasi Kwarteng admitted he did not know if the £1bn-a-year cost would fall on a buyer for the firm, the Treasury, or all customers’ bills.
Raising bills to cover the costs of propping up Bulb Energy, which failed in November, would be another blow to Brits as bills hit £2,800 a year this winter.
