Speaking on the back of ScottishPower's recent announcement that it was cutting gas prices on one of its tariffs by ten per cent, Ms King said that amount was "pretty pathetic", adding that "15 per cent across the board would have been a much better option".
Ms King issued a warning to the big energy companies, telling the newspaper: "We're seeing a return to Victorian times where people are freezing to near death.
"But why should one energy company have the right to cut its tariff while the others don't?"
Ed Monk, household utilities specialist for Thisismoney.co.uk, recently told the Daily Mail that consumers should definitely search for a better energy deal with another supplier.
