With the “rollback” taking effect every, eligible, teacher has had their 2015-2022 service returned to the final salary scheme and as a result “overtime” causes an issue for the administrators.
Overtime is NOT pensionable under the final salary scheme but IS pensionable under the career average scheme.
This means that if you had overtime in the remedy period you paid the pension scheme around 10% of that in return for some pension, just the same as you do for your normal wages. However, that should only happen if you are in the career average scheme and not if you are in the final salary scheme. The “solution” is for the scheme to refund you what you paid, but they really do not explain what you may be giving up if you take this refund.
