Commenting on the news that British Gas plans to increase fuel prices by six per cent net month Unite general secretary Len McCluskey said: "With winter approaching, low waged people will now be terrified about how they are going to find another £80.
"Money from the poor is going to the pockets of Centrica shareholders. This is further shameful abuse by out of control, greedy fuel companies, sitting on piles of profit. Alongside the government's punish the poor strategy, millions of households will be forced further and further down the path to poverty.
"It is high time that the government intervened to take back from these grasping companies. Why is it that when wholesale fuel prices go up, these companies take from customers, yet, when wholesale prices go down, they still take from customers?
"They are abusing their social responsibilities and weak regulation allows them to get away with it.
"Cap their profits, intervene to stop this racketeering or millions will face a cold, miserable winter."
