As of 12 March 2020, the Government has been advising all schools and other education settings in England against arranging or undertaking any overseas trips for children under 18.
All schools should check with their travel agent and credit card companies regarding securing refunds in the first instance. If unable to recoup their full costs, those academies signed up to the Risk Protection Arrangement (RPA) for schools should then submit their claims as per the RPA membership pack, and other affected schools should contact their individual insurance company.
