Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, what the cost to the public purse has been of correcting underpayments for universal credit to date; and what proportion of the Government’s total expenditure on universal credit has been spent on meeting that cost since the roll out of universal credit.

The information requested is not held by the Department.

The staff cost of correcting can not be disaggregated from other activity.
