Millions of UK households will receive an energy bill next month for a staggering Â£530 on average.
The huge bill will greet energy consumers who pay their bills quarterly.
Research has suggested that around 6.5 million households have already been left in fuel poverty this winter, in part due to the various price hikes imposed by many of the UK's energy suppliers.
The average energy bill now stands at a colossal Â£1,343 per household.
In fact, all of the Big Six suppliers in the UK, who are all part of the Warm Home Discount Scheme, have either raised their bills or, in the case of E.On, confirmed that price hikes will come into effect early this year.
Energy UK chief executive Angela Knight said: "With the current state of the economy, we know that people will be worried about their household bills after Christmas.
"Anyone who's concerned about paying their energy bills this winter should contact their supplier and see what options are open to them."
Late last year, the Government unveiled plans to force energy companies to limit their energy tariffs to a choice of only four, putting customers on the cheapest of these offerings, with energy secretary Ed Davis claiming the move would help simplify decisions for energy consumers. However, that policy is unlikely to come into place before 2014.
