Alan Higham, retirement director for Fidelity Worldwide Investment, has warned people to investigate retirement choices after a lack of planning was revealed.
Mr Higham said people should conduct their own research, use a financial adviser or the Pension Wise service.
He said: “The date of 6 April is not something that should be viewed as a target, reached at all cost and at the sake of vital research and careful consideration.
“Indeed, people may prefer to take their time to work through their retirement plans, which is an approach we would strongly endorse.”
Research among 525 UK adults who planned to retire in the 12 months following April 2015 revealed only 15 per cent had a clear retirement plan.
Mike McAnulty, director of Aberdeen-based Central Investment, said: “There is the concern that the reduction in tax charges on pensions will encourage individuals to draw down their funds sooner than originally planned.
“Your financial adviser will be able to help you plan how much of your pension can be touched while ensuring it is protected for the future.”
