It is estimated that 20,275 Brits more than average died between December 1 and March
An additional 2,000 deaths more than average were expected due to cold conditions between March 23 and 31, this winter’s average death rates show.
Campaigners have called the deaths a “national tragedy” as cold weather victims fatalities could be prevented – especially in the elderly.
According to the Office of National Statistics, one in 10 cold weather deaths are among under-65s, one in 10 among 65-75s and eight in 10 among over-75s.
The Department of Health also said cold conditions worsen winter killers including flu, chest diseases, heart attacks, strokes and dementia.
It means this winter is set to total at least 48,000 deaths due to cold weather – which works out at an average of one death every three and a half minutes.
National Federation of Occupational Pensioners chief executive Malcolm Booth said: “It’s shocking and disturbing that winter’s excess deaths look like exceeding 40,000.
“It’s a national tragedy, with so many families affected.
“Many who die are senior citizens. The elderly should make sure they eat hot meals, dress warmly and, if unable to heat your whole home, heat one room spend your time there.”
Department of Health chief medical officer Professor Dame Sally Davies, said: “Cold-related deaths represent the biggest weather-related source of mortality.
“There are too many avoidable deaths each winter, primarily due to heart and lung conditions from cold temperatures.
“It is vital to tackle the range of causes and reduce the number of ‘excess’ deaths each winter.”
A Department of Health and Social Care spokesperson said: “We’re absolutely committed to helping people live long and healthy lives.
“That is why the NHS was given top priority in the Autumn budget, with an extra £2.8billion on top of a planned £10bn-a-year increase by 2020-21.”
