Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, how many (a) large and (b) unusual underpayments have been referred for analysis since June 2023.

DWP measures its underpayments via annual national statistics published each May. However, we do not produce an estimate for the value of a benefit underpayment.

DWP conducts internal quality assurance checks focusing on financial accuracy and service quality.
