Under the conditions for continued receipt of Invalidity Pension you should not do any work while getting this pension.
However, you may, with prior written permission from us, be exempt from this rule to:
do a course of training which may lead to other employment, or
start light work or training that you would not normally be paid for.
Since 13 February 2012 you may be eligible to work and receive Partial Capacity Benefit instead of Invalidity Pension.
