I don’t mean to be rude but you’ve paid nothing for 4 months. I wouldn’t expect them to be claiming 30 hours, use 22 & then still ‘save’ the other 8 for your return, considering you weren’t paying anything during that period, and considering no one had a clue when that return may be, if at all.
Most nurseries were just trying to stay afloat & not go under, with no good guidance from the Gov.
Whether it’s correct or not, there’s only 5 weeks left. Just suck it up & pay, or send her less hours that you can afford. Or don’t send her back at all.
OP, unless you continued to pay nursery fees during lockdown when the nursery was closed, I would agree with the above with bells on. Nurseries will simply go under if you want your cake and eat it.
As a corollary, I continued to pay private school fees (with a 10% discount) during schools were closed even though the teaching was much reduced. I get that there is no option of remote childcare in the case of nurseries but I am also aware that if I did not continue to pay school fees, there won't be much of a school for my dcs to go back to. I cannot imagine nurseries would be in any better financial position, in fact probably worse. Unless parents share some of the financial pain of the nursery, there will be much reduced choice of early years childcare overall because childcare settings with simply close.
