Families who drop out of the eligibility criteria for the extra 15 hours will continue to receive these hours for a short time after. You will be notified by HMRC of the date your extra 15 hours will cease for your 3 or 4 year old, this is called a Grace period.
Once the extra 15 hours have ended, your 3 or 4 year old will still be eligible for the universal 15 hours per week for 38 weeks (or 570 hours across the year).
Please note: families cannot claim the extended 15 hours for the first time if the family are already in the grace period. However, if parents who were already claiming the extended hours want to move their child to another setting but are in the grace period, the extended hours can still be claimed at the new provider.
