Ofgem boss Andrew Wright has acknowledged a "deep distrust" of energy companies among consumers and said he "completely understands" frustration and anger about rising bills.
The energy regulator's chief executive told the Commons Energy and Climate Change Committee that consumers were not convinced that price increases were either fair or justified.
He said: "I completely understand why people feel frustrated and angry about rising energy bills. Prices have more than doubled over the last 10 years at a time when incomes have been squeezed, and consumers are not convinced that price increases that they see are either fair or justified."
