Buying pension lost due to absence

If you have a period of authorised leave of absence on no pay (otherwise than because of illness or injury, or ordinary unpaid additional child related leave, or reserve forces service leave), or a period on no pay due to a trade dispute, you will not be building up pension during that period.

However, you can, if you wish, buy back the amount of pension you lost during that period by paying Additional Pension Contributions (APCs).
