The Pensions Policy Institute (PPI) has published the results of its ‘Lost Pensions: The scale of the challenge’ survey, revealing that over 3 million UK pension pots remain lost, with a lower-bound estimate of £18.7 billion in total assets and an average pot value of £6,220. Supported by the Money and Pensions Service (MaPS), the survey covers around 75% of the workplace defined contribution (DC) market by pot numbers. Its revised methodology means the findings are not directly comparable with previous estimates, and some lost pension wealth may not be fully captured. Most lost pots (81.88%) belong to members aged under 55, which the report attributes to restrictions on accessing pension savings, employment patterns, automatic enrolment and higher job mobility among younger workers. Although members aged over 75 hold only 0.26% of all lost pots, 13% of all pots in this age group are considered lost. Women’s lost pots are worth over 20% less on average than men’s, at £5,370 compared with £6,830. The survey also includes exploratory evidence on defined benefit (DB) pensions for the first time. This suggests that lost entitlements exist across scheme types and may affect member outcomes, but improved data are needed to establish their scale and value reliably.
