Private pensions play an important role in the provision of income in retirement in the UK, although their role has evolved over time. While defined benefit (DB) pensions were prevalent in earlier decades, the importance of defined contribution pensions has been growing and will continue to increase in future years, especially for later cohorts. In particular, the introduction of auto-enrolment from 2012 is expected to increase pension coverage and the amount of pension wealth individuals accumulate before retirement, much of which is likely to be in DC schemes.
