You will see from the information on this site under education that if you have a disability that creates considerable needs and you are aged under 25, and in Further Education, you are likely to qualify for an Educational Health Care Plan which will pay for your support needs and your course. If you are doing a Higher Education course at a university or college at Level 4 or above, you are likely to qualify for Disabled Student Allowance. There are, however, some charities that will help with any costs that are not covered or for those who do not have this funding.
One option is the Snowdon Trust. https://www.snowdontrust.org/. Who will fund Further Education, Vocational Education or Higher Education costs related to a person's disability (physical or sensory). They have a long history since 1981 and grants (that do not have to be paid back) can fund help, like sign language interpreters, other vital human support, specialist equipment or additional accommodation costs such as a Carer.
They also have a Masters Degree Scholarship Progamme.
