If your child is registered for Pupil Premium (aka Free School Meals), they will be entitled to free school holiday food and activity clubs via Hampshire County Council's HAF programme which provides healthy food and enriching activities in the school holidays to children who receive benefit-related free school meals.  

There are many club providers, including ones local to us here in New Milton.  https://fish.hants.gov.uk/kb5/hampshire/directory/advice.page?id=XRlTDNF8hhM
