We will lose out on childcare vouchers and probably won't get much out of 10 hours free childcare unless we can have it as one free day of nursery - 2 hours just doesn't work for us, we would need a decent block of time. I would love a scheme which allowed me to have one or two free days of nursery for my DCs at some point, it would help us far more than chidcare vouchers do.
It's disappointing but,
Childcare vouchers mean a very small amount of money in relation to childcare
They benefit higher rate taxpayers more than basic rate tax payers - I'd prefer help towards childcare which is more equally available to everyone, not just means tested. You also have to be earning a certain amount to get them, and probably working a certain amount. Many part time workers especially if they're just one or two days a week and/or quite low paid probably are ruled out of vouchers anyway.
If you sign up for vouchers before 2011, you can apparently continue to get them until 2015, which should be some consolation to some people here
I didn't get round to getting vouchers when I returned to work after my first maternity leave, as I was pregnant again in less than 3 months and I was worried about losing more in pay in my maternity leave than I would gain - it didn't seem to make sense to join, leave and join again to avoid that, and I didn't know about the loopholes that mean you can get vouchers on top of SMP (all a bit over complicated anyway). DP is signed up for the vouchers.
The other thing is vouchers have implications for some benefits and future income for some people. My employer and dp's allow you to do it without losing out in the final salary pension scheme, but some employers don't (as you may have your pension calculated on a lower wage).
I don't like the proposal much but think the Tories' plans will have a far worse impact - cutting Surestart, cutting public spending etc.
