@713945cf the 17% is the increase in the total(s) being withdrawn...the average withdrawal this year was just over £7k, so provided the pension pot was over £200k, they'd be within your limit
@43d7c4ea the figure I'm seeing quoted is an expected for 55-64 year old of £107,300 at state retirement age (much more for men than women). I'm unclear to what extent this estimate includes the imputed value of defined benefit schemes and annuities. If the average annual withdrawal is £7k from draw-down schemes then this suggest a drawdown of well over 4%.
