My 3 yo attends five sessions of pre-school - funded 15 hours. However, they also want a top-up per session - they say it is voluntary but are implying it isn't really voluntary and must be paid. I am happy to pay what we can towards a top-up but just can't afford the amount they are requesting. Is there somebody I can contact to query whether it is legal to enforce this payment? The council? Lea? Any advice appreciated.
