A staggering 15,000 plus households in Doncaster are now in fuel poverty, putting lives at risk, a government report has shown.
Figures from the Department for Business, Energy and Industrial Strategy show that 12 per cent of households in the area would be pushed into poverty by the cost of heating and lighting their homes properly.
Across Yorkshire and the Humber, around 270,000 households are in fuel poverty. Large households, single parent families and private renters are seen as particularly vulnerable.
Each household is short of their required energy bills each year by £252 on average - forming the 'fuel poverty gap'. The fuel poverty gap in Yorkshire and the Humber is the lowest in the country.
A household is considered to be 'fuel poor' if they have fuel costs which are above the national median average and if meeting those costs would push them below the poverty line.
In a study published earlier this year by fuel poverty charity National Energy Action and climate-focused think tank E3G, it was estimated that fuel poverty accounts for over 1,000 excess winter deaths in England every year.
Peter Smith, co-author of the study and director of Policy and Research at NEA, said: "We know that living in fuel poverty causes winter hardship and premature mortality.
"It's been shown by not only our charity but also the Committee on Fuel Poverty that the government's existing set of policies aren't sufficient in scale to address the problem."
Across England, fuel poverty hits larger households hardest. Households with four or more occupants are more than twice as likely to be in fuel poverty and have an average fuel poverty gap £100 higher than households with three or fewer occupants.
The figures also show that over a quarter of single parent households are fuel poor - a dramatically higher rate compared with the national average, and nearly twice as high as the rate for couples with children.
Households in private rented accommodation are twice as likely to be in fuel poverty than the national average, and have an average fuel poverty gap of £383 - nearly twice as large as households in social housing.
In 2018 the Government predicts that the proportion of households in fuel poverty will decrease slightly, but that rising energy prices will push the national average fuel poverty gap up by nearly 10%, from £326 to £357.
A BEIS spokesperson said: "We don't want anyone to live in fuel poverty.
"We are introducing a temporary price cap to stop rip-off price rises and unjustified energy prices for households on standard variable and default tariffs.
"We're also tackling the root causes by investing £6bn in improving energy efficiency in some of the UK's poorest homes over the next 10 years."
However, Mr Smith says that the Government definition of fuel poverty fails to take into account families already below the poverty line, for whom even 'low fuel costs' are unaffordable.
He says that NEA also wants to see fuel bill discounts and energy price caps, available to those on benefits, offered to working families with low earnings.
