Investigation into underpayment of State Pension

In early 2020 the Department for Work & Pensions (DWP) became aware of underpayments of State Pension affecting certain women who reached State Pension Age before 2016. Subsequent DWP investigations uncovered systematic issues meaning that tens of thousands of people might have been underpaid State Pension for many years. DWP is currently working to identify all affected individuals and began making repayments in January 2021.

This NAO investigation will look at who has been underpaid and why, how this happened, what DWP is doing to put it right and what lessons DWP has learned.
