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.
