A map showing the coldest homes in England has been published to encourage vulnerable people to stay warm and healthy during the winter.
The DoH said a cold home can have a serious impact on people's health
The Department of Health (DoH) map marks the launch of the Keep Warm Keep Well campaign advising the elderly, poor and disabled on how to stay warm.
Liverpool was the coldest place on the "cold homes" map - 28.8% of people aged 65 or over are without central heating.
Cash for heating is offered by the Warm Front Scheme and Winter Fuel payments.
The DoH said that living in a cold home can have a significant effect on people's health, and is linked to heart and respiratory problems, serious illness, discomfort and depression.
Health Minister Ivan Lewis said: "It is vital to look after yourself and stay warm and well during the cold winter months.
"Cold homes have a significant impact on people's health and wellbeing.
"There are millions of pounds of grants available for help with insulation and heating systems, and fuel payments to help older people, those on low incomes and disabled people."
"I urge people to plan ahead and find out what help is available and what measures they can adopt to ensure they are protected against the winter."
In 2005/2006, more than 11,625,453 winter fuel payments were issued worth £1,776,849,550.
