Trust funds are sums of money set aside by individuals or organisations to help specific groups of people and are usually provided in the form of a grant or loan. Generally the amount of money is small and is aimed at assisting with living costs, fees, course equipment, travel, childcare, etc.
There are thousands of trust funds, so you need to find the one that matches your personal circumstances - do not waste time and money by applying to trusts that are not relevant to you.
