The older people's charity Anchor has warned politicians not to take the 'grey vote' for granted.
In a statement issued 100 days before the general election it says only 13% of those aged 55 and over think politicians represent the views of people their age.
Research revealed the health and social care as the top political issues for grey voters with 86% of those polled saying this should be the focus for politicians.
The survey results showed 79% of over-55s highlighted tackling terrorism as a key issue and 69% wanted political leaders to focus on the economy. Concerns over pensions and savings were highlighted by 51% of those surveyed.
Anchor says the survey exposes a shift in political alliance, with nearly a quarter of those planning to take part in the election said they were not going to vote for the same party they supported in 2010.
Nearly a fifth were undecided whether to vote the same as last time and just over half said they will be voting as they did five years ago.
Older people appeared to show commitment to the electoral process, however, with 93% of saying they are planning to or likely to vote at this year's general election.
Jane Ashcroft, Anchor chief executive, said politicians were failing to represent the views of older people adequately.
She said: 'With only 100 days before the general election, and many older people still yet to decide on their vote, now is the time to take action to ensure that the grey vote is considered and adequately represented by all political parties.'
