Many over 55s could be missing out on thousands in retirement savings by overlooking a simple yearly step.
Experts warn that failing to act now means opportunities to boost pensions and secure a more comfortable future, may be slipping away.
The study by Standard Life found that 17 per cent of people in this age group have never checked their retirement funds.
Experts warn that without regular reviews older savers could miss vital opportunities to boost their pensions in the years leading up to retirement.
Gail Izat, Managing Director for Workplace Pensions at Standard Life, part of Phoenix Group said: "Your pension pot might not need daily attention like your bank account, but checking it at least once a year is a smart move.
"With one in seven people never reviewing their pensions, many risk missing opportunities to boost their savings or even risk losing track of their pots altogether."
The findings emerge during Pension Engagement Season, a campaign aimed at encouraging people to pay closer attention to their retirement savings.
Across the wider population 14 per cent of adults, around one in seven, have never reviewed their pension savings.
Women were more likely than men to neglect their pensions, at 14 per cent compared with 11 per cent.
By contrast younger adults show stronger engagement with retirement planning.
Only 12 per cent of those aged 18 to 34 said they had never examined their pension, while the 35 to 54 age group performed best with just 8 per cent failing to check their savings.

Despite recommendations to review pensions at least once a year only 56 per cent of adults do so.
Weekly monitoring is rare, with fewer than one in 10 checking their workplace pension every seven days.
By comparison 35 per cent of people examine their cash savings weekly and 18 per cent check investment accounts as often.
The research suggests many treat pensions as "set and forget" investments, even though small changes could have a significant impact on retirement outcomes.
Among those who did engage with their pensions in the past year one in five looked at their projected retirement income.
Some took further steps to improve their prospects.
Fourteen per cent increased contributions, 11 per cent adjusted their investment risk levels, one in ten made lump sum payments, and 9 per cent consolidated multiple pension pots.
But the majority who reviewed their pensions took no action, leaving them at risk of falling short of their retirement goals.

"As retirement gets closer, staying on top of your pension becomes even more critical," she said.
Ms Izat also explained that providers issue annual statements to all workplace and personal pension holders, but these can be requested if not received automatically.

Many companies now provide mobile apps, allowing people to check balances, contributions and projected retirement income at any time.
She added that pension calculators can help determine whether savings will meet retirement lifestyle goals, and that both regular and one off payments can be made to boost future income.
