In April 2010, Judge was appointed chairman of the Pension Protection Fund (PPF), which provides compensation to employees with pension schemes in bankrupt firms. She was the first woman to serve in the role. She was reappointed as chairman in 2013 and completed her second (and maximum) term in July 2016. She advocated that the pension regulator be given the power to block companies from deals that would harm pension scheme members, referring to Sir Philip Green's sale of British Home Stores to Dominic Chappell. Judge was a supporter of auto-enrolment in pension schemes.
