Working more or fewer hours
Going to work more or fewer hours per week,
will affect your pension
Working more or fewer hours in a week has an influence on your pension accrual. This is because your income will change in most cases and so, therefore, will your pensionable base.
This will result in your annual pension accrual being either higher or lower. This clearly has no effect on the pension rights already accrued. Salary changes as a result of working more or fewer hours are processed immediately in the pension-administration system.
