Age Concern has launched the Take Control campaign to help older people take action to lift themselves out of fuel poverty.
The campaign and helpline (0800 33 66 99) is targeted at older people, their friends, neighbours and family members, all of whom can help to ensure that older people are not left cold in their homes.
Research carried out by the charity revealed that four in ten over 55s felt poor heating could have a negative impact on their health.
Raymond, an 80-year old pensioner, said: "The helpline staff were really friendly and helpful and after speaking to them my bungalow was insulated for free.
"This has reduced my fuel bills and will make my home more energy efficient for the coming winter."
Gordon Lishman, director general of Age Concern, said: "Fuel poverty remains a serious problem. There are 2.5 million households in fuel poverty in England this year; twice as many as there were in 2004.
"Older people should be able to afford to heat their homes and often they just don't know how to get the advice and support they need."
It is hoped the campaign will enable older people to take advantage of schemes to make their homes more energy efficient.
