You've a bit of planning to do, and it depends on the size of your pension pot, and if you're already getting maximum tax free lump sum, etc.
There's no point deferring pension benefits during a period you've no taxable income if ultimately you're going to pay a higher rate of tax when you start taking pension benefits.
Assuming you're about 40 now, completely debt free, you might also look at ways of increasing the amount of money going into your pension. For example does your nature of work allow you to become self employed? Or could you change jobs / contracts so that employer is making a larger pension contribution.
