The current employer supported childcare voucher scheme closed to new entrants on 4th October 2018. If you were already in the scheme and had received your first voucher before 4th October you will not be affected.
Should you have a break in receiving vouchers for more than a year you will no longer be eligible for the scheme. If you move employer unless it’s part of a TUPE agreement you will also no longer be entitled to claim the vouchers.
The new scheme in place is called Tax-Free Childcare (TFC) and more information regarding the scheme and how employees can apply can be found here on Childcare Choices
