Question to the Department for Work and Pensions:

To ask His Majesty's Government what data they hold on the number of years on the National Insurance records of all UK residents and citizens and what assessment they have made of the potential cost savings that would be incurred by increasing the number of qualifying years for a full state pension from 35 to 48.

The Department holds information on individuals' National Insurance contribution records, including qualifying years relevant to State Pension entitlement. DWP has made no assessment of the savings arising from increasing the number of qualifying years required for a full State Pension from 35 to 48.
