Each nursery will be different Some spread it out over the full year Some do term time only, meaning higher bills in school holidays Some charge for sundries, some don't As above my nursery only allows the hours to be used outside of certain times
You need to ask your nursery for a breakdown and explanation of costs.
So it works out as 9hrs per week for full year (15hrs term time only) . My nursery is offering the funded hours in blocks 8-12noon and 1-6pm is funded, but we have to pay for the lunch hour 12-1pm due to more staff being needed. So it is roughly one day per week free but it depends how your nursery uses the funded hours.
