The University and some colleges use Salary Exchange for employee contributions. If you are in Salary Exchange your employer pays your pension contributions and reduces your pay by the same amount. This means that if you take a refund on leaving any contributions taken through Salary Exchange cannot be refunded.
If you are a University employee think you might want a refund upon leaving you should strongly consider signing and returning the Salary Exchange opt out form within three months of joining. You should send this form to the University payroll office.
If you are an employee of a college that operates Salary Exchange you should contact them about their opt out procedure.
