Sage has no control over your pension, and can't be managed in Sage HR.
If you have a query about it, such as how to opt out of your pension, increase or decrease your pension amount, view your pension balance etc. you must contact your pension provider.
If you don't know who your pension provider is, please contact your employer, they will be able to clarify this for you.
