More than three million low-income households cannot afford to heat their homes, research shows today as Britain prepares to shiver.
The UK Health and Security Agency has issued a cold weather alert recommending vulnerable people warm their homes to at least 18C, wear extra layers and eat hot food to protect themselves from plummeting temperatures.
But some 710,000 households are unable to heed the advice as they cannot pay for warm clothing, heating and food, according to analysis by the Joseph Rowntree Foundation.
A fifth of all low-income households - 2.5 million - are going without food and heating.
The survey of 4,251 people in the bottom 40% of incomes also found that around 4.3 million curbed their spending on heating ahead of the cold spell.
The survey was conducted from October 31 to November 25.
More than seven million households have gone without at least one of the essentials since June, the Foundation will say in a report next week.
It found that many families are already in arrears on their bills, owing more than £1,600 on average.
Around 2.4 million households have borrowed money or used credit to afford their bills so far this year.
Freezing weather means they face the impossible decision over whether to take on more debt to heat their home to the level recommended by health professionals.
Rachelle Earwaker, senior economist at the Joseph Rowntree Foundation, said: "The Government must see that families won't be able to get through the winter on the current levels of support.
"For hundreds of thousands of households it's not a choice between putting the heating on or not.
"Our research shows they can't afford anything recommended to protect themselves from the effects of plummeting temperatures.
"We're still experiencing historically high inflation and the prices of essentials are still soaring. Energy bills, while capped, are still almost double what they were last winter."
A Government spokesperson said: "Our priority will always be to support the most vulnerable and we recognise that people are struggling with rising prices which is why we are protecting millions of those most in need with at least £1,200 of direct payments and providing households with £400 towards energy costs.
"Our immediate support also includes our Energy Price Guarantee, saving around £900 for a typical household over winter and our Household Support Fund is helping people with essential costs.
"Meanwhile the Chancellor recently announced a further extensive cost of living package, ensuring those most in need are supported next year as well as this."
