Most over-55s expect to have spent - or expect to spend - a third of their pensions tax-free lump sum within the first six months of taking it, according to a new study.

The study, by provider Standard Life, found that women were more likely to spend a larger proportion of their tax-free cash in the first few months than men.

The research from Standard Life, part of Phoenix Group, also found that 11% of over-55s expect to spend - or have spent - between 90% and 100% of their tax-free pension pot within half a year of withdrawing from it.

Just over a quarter of over-55s (27%) do not know how much they will spend or have already spent.

Standard Life’s research also found that women who took or plan to take a lump sum at the point of retirement spend 37% of their pot on average, compared to men spending 29%.

Dean Butler, managing director for retail at Standard Life, said that some people may be using the tax free cash to reduce their working hours or start phased retirement but this could harm long-term retirement income later on as pension pots grow.

He added that for some over-55s taking the tax-free lump sum in chunks over time could be a tax-efficient way of withdrawing pension savings.

More than one in four over-55s (26%) believe they will still be working past 70 due to the cost of living crisis, according to a new survey.

Almost a third of people aged over 55 are changing their retirement plans due to the current cost of living crisis, according to new research.
