A quarter of over 55s earning a salary are not paying into a pension, research from Confused.com has revealed.
Among those who don't have a pension, less than one in five (17.5%) of all earning adults in the UK have any other investments to fall back on either.
There seems to be a knowledge gap when it comes to retirement too, with nearly half (43%) admitting they don't know what an annuity is.
Meanwhile, 26% of people didn't know they could take a lump sum payment from their pension fund at retirement.
The lack of preparation is worrying, given that 12% of over 55s says they expect to still be in debt when they retire.
"With potentially no income and reliant on a state pension of £110.151 a week, these over 55s are likely to struggle to cover increasing costs of living and also pay off outstanding debts," said Confused.com.
Kate Rose, head of annuities at Confused.com, added: "Retirement should be the time when we put our feet up and enjoy life after decades of work; yet so many of us are underprepared. It's staggering that so many people due to retire in the next 10 years are unaware of their options.
