Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, what recent estimate she has made of the amount of underpayments resulting from claimants in receipt of personal independence payment being paid a rate of employment and support allowance or the limited capability for work component of universal credit, including associated premiums, that does not fully reflect their PIP entitlement.

The Department publishes annual statistics on fraud and error in the benefit system, which are available here: https://www.gov.uk/government/collections/fraud-and-error-in-the-benefit-system. These include estimates of underpayments due to errors relating to premia and income from other benefits. The information requested on the total number of claimants receiving ESA or Universal Credit payments inconsistent with their PIP and other relevant living and care arrangements is not available and it would incur disproportionate cost to determine this number.
