It is something I earned and paid for!
State Pension is deemed a contributory benefit because people pay National Insurance Contributions as a tax on their earnings just as a workplace pension is a contributory benefit because people pay into a pension fund from their earnings. But as others have pointed out, it is not a personal pot. It's a general pot called the National Insurance Fund into which NIC paid by employers, employees and self employed is paid (after the allocation to the NHS). Out of this are paid current contributory benefits including maternity and bereavement benefits, the contrubutory element of JSA and ESA and one or two others. 95% of what is paid out from the NIF is State Pension.
Some who reached State Pension age before 6 April 2016, around 720,000, receive a State Pension for which they did not pay NIC. It’s effectively a legacy system which acknowledges that older pensioners, women primarily, either did not work outside the home, paid the small stamp or inherited pension from a late spouse.
For people who reached State Pension age before 6 April 2016, there are four categories of State Pension: A, B, C and D (and blends of A and B).
Only a Category A pension is wholly contributory.
The Category B pension is primarily paid for married women who paid the small stamp, which was not a contribution to the State Pension so is based on the husband’s NIC. A married man paid the same rate of NIC as a single person so no additional contributions have been paid towards the Category B pension which is paid at 60% of the rate of Category A.
A married man who did not pay NIC can also get a Category B pension claim based on his wife's NIC.
This system applies only to those who reached State Pension age before 6 April 2016.
There are also Categories AB, ABL and BL where the pension comprises a mix of entitlement where some NIC has been paid for the Category A part. The B element may include State Pension inherited from a late spouse.
The Category C pension is rare now, primarily paid to widows of individuals who reached pensionable age before 5 July 1948. It is non-contributory. In August 2025, there were only 8 people receiving this.
The Category D pension is paid to people age 80 or over and who have not paid any NIC. Claimants must have lived in the UK for at least 10 years out of any 20-year period (which must include the day before they turned 80 or any day after). In August 2025, there were 93,207 people receiving this. People who reached State Pension age on or after 6 April 2016 cannot claim this.
The vast majority of people who reached SP age before 6 April 2016 paid NIC and receive Category A only, some 5.2 million.
In August 2025, there were were just under 3 million people receiving pensions under categories AB, ABL, B, BL, C and D.
Of these, around 720,000 are B, BL, C and D, people receiving pensions for which no NIC was paid. (Source StatXplore).
The rate of Category B, C and D pensions is currently £106.70 per week rising to £110.75 from 6 April 2026.
