More than two thirds of Scottish people are worried about affording their energy bills this year, while many already feel cold in their own homes.
A Survation poll for Advice Direct Scotland also found that 65% of Scots said they have already limited their energy use in the past 12 months so they could afford to spend money on other goods or services, including food.
The research was carried out days before energy regulator Ofgem revealed that fuel bills will typically rise by £693 a year in the UK from April as it raised the price cap.
Scotland’s Energy Secretary Michael Matheson has warned there is a “real risk” people could die in the months ahead as the country faces a major increase in energy prices.
The Advice Direct Scotland research asked people how worried they were about being able to afford their energy bills this year, with the price cap due to be increased.
Seven in 10 of the 1,008 respondents said they were either very worried or quite worried.
Among those rationing their energy usage, 29% said they often feel cold in their own home as a result and 57% said they sometimes do.
Andrew Bartlett, chief executive of Advice Direct Scotland, said: “This stark poll demonstrates the scale of the cost-of-living crisis in Scotland.
“Thousands of households are already rationing their energy use so that they can afford necessities such as food - and, as a result, many are cold in their own homes.
“The looming energy price hike is causing considerable anxiety, with 70% of Scots worried about affording their bills.”
The poll was carried out at the end of January, before the price cap increase was announced on 3 February.
Chancellor Rishi Sunak has promised all households a £200 discount on power bills in October, that will have to be repaid over five years.
Advice Direct Scotland runs the national service advice.scot, along with energyadvice.scot, which gives free advice on billing, grants and assistance.
The service has received more than four times the anticipated level of inquiries since it opened in April last year.
It said that common concerns are big jumps in monthly direct debit payments, how these extra costs can be met, and worries about what happens when your supplier goes out of business.
Advice Direct Scotland also administers the Scottish Government’s £4m Home Heating Support Fund for those rationing their energy use, which “referral partners” such as housing associations, local authorities and charities can access on behalf of their clients.
