Hampshire County Council has a small discretionary fund which can be used to help with school clothing for primary age children. For further information, call Children's Services. Tel: 0300 555 1384.
Unfortunately there is no clothing assistance available for secondary age children.
However, if your child attends an Academy, you should contact the Academy directly to find out what help might be available. Academies receive direct government funding to provide a number of services, including pupil support (e.g. school uniform grants) and therefore may be able to assist you.
