If you opt for Flexi-Access Drawdown, you can leave your money in your pension pot and take lump sums from it as and when you need, until your money runs out or you choose another option. You can decide when and how much to take out. Any money left in your pension pot remains invested, which may give your pension pot a chance to grow, but it could go down in value too. Each time you take a lump sum, normally a quarter of it is tax-free and the rest will be taxed. You may need to move into a new pension plan to do this.
