Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what steps his Department takes to ensure that employers share accurate (a) data and (b) instructions with Civil Service Pensions; and how often this is audited.

The Cabinet Office ensures employer data accuracy through a mandatory Interface Compliance Process, in place since 2018, which monitors the quality of all data and instructions against a 'right first time' standard. This process flags all Errors and Warnings on monthly submissions. The administrator, MyCSP, does not load the following month's data until all previous errors are corrected, ensuring a continuously maintained data quality. Compliance is audited weekly by the administrator, with summary reports provided to the Cabinet Office.
