Households have seen their average utility bills rise by 168% over the past 10 years, according to new statistics.
The average annual energy bill of £1,265 is £53 higher than a year ago and £793 higher than in 2004, it is revealed.
A poll by uSwitch also found that almost four million households are now in debt to their energy supplier and typically owe £128.
Even though it was a mild winter there has been a succession of price rises and these are cited as the key reason why there has been a £5 increase in the amount of debt owed by the 14% of households that are in the red.
And as average utility costs are rising it seems many consumers may be trying to avoid the issue altogether, as one in four (25%) are "turning a blind eye" to their debt in the hope that it will diminish over time.
Around one in five (21%) plan to pay the debt off with a lump sum, while around two in five (43%) intend to increase their direct debit.
Ann Robinson, uSwitch director of consumer policy, advises households to make sure their supplier receives regular meter readings because estimated bills can result in increased debts.
She also cited the importance of being able to switch energy suppliers as there is a difference of more than £300 between the cheapest and priciest energy tariffs currently available.
