Nearly one in 10 adults believe they will never retire, and a further one in eight think they will be aged between 71 and 80 when they finally get the opportunity, research has found.
Figures from a joint study by Co-op Funeralcare and Co-op Legal Services showed that 9 per cent of adults believe their working lives will never end.
It also showed that women were more likely than men to put off retirement.
Further research, carried out specifically among people aged over 50, showed that financial concerns were a key reason for delaying retirement - 22 per cent of those surveyed said they needed to keep working due to a lack of retirement funds.
One in five (21 per cent) said they had chosen to work for longer because they liked their job.
For 11 per cent of over-50s, retirement was not an option due to having debts to pay off, while 7 per cent still had mortgage repayments to fulfil.
A further 8 per cent of those surveyed kept working due to financially supporting their children for longer than they had expected.
The research was taken from a survey of 2,000 adults across the UK as well as a survey of more than 1,000 people aged over 50.
