Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, if he will make it his policy to (a) collect and (b) publish management information on the number of people who have (i) had changes to their National Insurance record and (ii) are waiting to have their state pension calculation updated.

DWP does not publish this information as changes to a citizen’s National Insurance Record forms part of HM Revenue & Customs (HMRC) function. When DWP receives notification from HMRC of a change in a citizen’s National Insurance record, DWP reviews the State Pension claim accordingly.

The vast majority of changes to a citizen’s National Insurance Record are processed by DWP within days. However, more complex cases requiring specialist caseworkers can take longer to resolve.
