The charity said 83,799 people have turned to its website for help with increasing energy bills since SSE announced the first price rise on 10 October.

British Gas, npower, Scottish Power and EDF Energy have also announced price increases.

It comes as E.ON, the only one of the big six energy companies in the UK that has not yet announced an increase in its tariffs, said a price hike was “increasingly likely”.

Although E.ON said its profits had increased from £194m to £227m for the six months to 30 September, it said it had been running the business at a loss of £37m for the period.

The company blamed increasing costs of distribution and government schemes.

“Whilst we will not comment on speculation, it is fair to say that we are being put in a position where it is increasingly likely that we will need to pass on some of these increases in costs to our customers,” said E.ON’s UK chief executive, Tony Cocker.

Earlier today the National Audit Office (NAO) warned that energy and water bills could continue to rise for the next 17 years due to the fact that new investment in infrastructure is expected to be paid for by consumers through their utility bills.

Citizens Advice chief executive Gillian Guy called for a “sustainable plan” for how Britain’s energy needs will be met in the future.

“An extra £200 on top of current prices would break many households which are already forced to make the impossible choice between heating and eating,” she said.
