Energy UK: Company profits 'not big'
The energy regulator Ofgem is not doing enough to ensure that energy company profits are transparent, MPs have said.
The Energy and Climate Change Committee (ECCC) report said the watchdog was "failing consumers by not taking all possible steps to improve openness".
The committee said that "working out exactly how their profits are made requires forensic accountants".
Angela Knight, of Energy UK, said the profit that an energy company makes is not particularly big but households are concerned.
