A form of drawdown pension that was available between 6 April 2011 and 5 April 2015 for a member of a defined contribution arrangement under a registered pension scheme. If a member satisfied a statutory minimum income requirement, there was no limit on the annual income a member could withdraw under flexible drawdown. This option has been superseded since 6 April 2015 by the flexi-access drawdown fund. (Section 165, Finance Act 2004.)
