The government has been facing growing calls to do more to help Britons facing energy bills which are set to jump 80% to an average of 3,549 pounds ($4,140) a year from October as wholesale gas prices hit record highs.

The YouGov poll for the Times newspaper found 47% of those who currently plan to vote Conservative at the next election favoured returning the energy companies to public ownership, with 28% percent opposed and 25% unsure.

Among those who voted for the Conservatives at the last election in 2019, 53% backed renationalisation.

Britain's energy suppliers were privatised by Conservative Prime Minister Margaret Thatcher more than 30 years ago. While the opposition Labour Party has previously called for renationalisation, current leader Keir Starmer has said the money would be better spent directly reducing people's bills.

Foreign Secretary Liz Truss, the frontrunner to succeed Boris Johnson as prime minister in a contest due to run until Sept. 5, has said she favours using tax cuts rather than direct payments to help people with the cost-of-living crisis.

The YouGov poll, conducted on Tuesday and Wednesday before the latest rise in energy bills was announced by the regulator, found 55% of those questioned said they would need to turn down their heating or limit its use over the coming months.

It also found 21% said they would not be able to heat their home "except on a very limited basis", and 5% did not believe they could afford to heat their home at all.
