Thousands of people have signed a petition calling on the Government to freeze energy bills.
Four of the so-called Big Six energy companies – including British Gas and npower – have announced inflation-busting price rises for customers this winter.
Figures show that 5,473 households across Chesterfield are spending more than ten per cent of their income on energy bills and are classed as being in fuel poverty.
In just three weeks, almost 4,500 people have added their names to a petition urging the Government to freeze prices.
Chesterfield MP Toby Perkins, who started the campaign, said: “Our energy market is broken.
“Falls in wholesale fuel prices aren’t being passed on to consumers as the energy bosses rake in increasing profits.”
Labour leader Ed Miliband added: “Hard-pressed people across Britain are struggling to meet the cost of their sky-rocketing energy bills as the Big Six suppliers make astronomical profits.”
Prime Minister David Cameron told the House of Commons he wanted the system to be fairer.
He said: “I want more companies, I want better regulation, I want a better deal for consumers.”
