A third (34%) of those who retired in 2020 planned to continue some work.

A quarter (24%) of the 2022 retirees surveyed by Abrdn Financial Planning said they aimed to work part time in the same job or a new one, 15% planned to continue to work for their own business and 12% planned to start their own business.

The main reasons cited for choosing flexible retirement were the need for income (31%) and wanting to keep busy (32%).

Fewer than three in 10 (28%) had taken financial advice and only a quarter (25%) were aware of the potential tax implications of drawing a pension while still working.

Only a quarter (25%) of 2022 retirees said they were very confident that they had saved enough to fund their retirement, in comparison to 30% in 2021.

Over a quarter (27%) said they did not know how to mitigate the impact of rising inflation on their retirement income.

Colin Dyer, client director at Abrdn Financial Planning, said: “Gone are the days when everyone had a set date or a set age from which they’ll never work again. The emerging trend for ‘flexi-retirement’ for financial reasons, or just to keep busy, is here to stay. The Class of 2022 are challenging the norms and doing what works for them.

“Hearing why retirees are choosing to work really underlines the importance of taking a holistic approach to retirement and how sensitive plans can be to external issues, such as the surge in the cost of living or the pandemic.”
