Hi my sister has started work and confused how childcare works for uc. It will vary each month. Does it mean each month she has to declare a change in the cost. Its the same provider. But some months DN will be in childcare 30 hours some as little as 5 depending on sister shifts. She knows she gets it back in arrears. If her uc dates are 3rd to 2nd. And she pays on 1st for the month ahead does she submit that straight to UC the say she pays. At the nursery she will use its paid in advance.
