I tried to do this today because I am going back to work at the end of the month and have received the invoice already to pay for when my daughter starts nursery. Our childcare costs are £12,000+ so the calculators all tell us that tax free childcare rather than vouchers is the way to go. However I tried to set up my account and the gov website says only when I am 14 days from starting work, this seems to be cutting it really fine? Any experience would be greatly appreciated! Every penny helps for this first month when I won't actually have been paid anything. Thanks
