From NHS guidance:
If I join Busy Bees will it affect my NHS pension?
The NHS Pensions Agency has confirmed that the value of childcare vouchers cannot count as pensionable pay. This means that you will not pay pension contributions on the value of childcare vouchers you receive as part of your salary.
NHS Pension Scheme benefits are based on pensionable pay, therefore should any benefits (e.g. Ill Health Retirement, Early Retirement, or Death Benefits) become payable whilst you are participating in the scheme, or within a year of leaving the scheme, they will be reduced.
Providing you ensure that you are not receiving Childcare Vouchers for three years before retiring or leaving the NHS your overall pension will not be affected.
For further information please contact your Pension Advisor on 01284 829593
What happens if I am an employee and I expect to have some maternity leave?
Statutory Maternity Pay (SMP) is calculated on the amount of average weekly earnings during the 8 week period, fifteen weeks prior to the expected date of confinement. A ?salary sacrifice? arrangement will reduce the amount of salary that is liable to National Insurance contributions. Therefore any ?salary sacrifice? entered into during this 8-week period will reduce entitlement to SMP.
If you are receiving SMP and maternity pay you should contact the HR & Communications department to find out whether you are receiving sufficient income to enter into a ?salary sacrifice? arrangement and receive childcare vouchers after taking into account your other financial commitments which are deducted at source whilst on maternity leave.
