Finance for PG study is not automatic. You may get offered a place but be asked to provide your own finance.
Always write to the course provider in the first instance who will tell you whether financial support is available.
Funding, if you are offered it, consists usually of payment of fees and a grant to cover living expenses.
Use the Postgraduate Funding Guide in the Careers Service to check your likely source. This will at least help you to know whether you would be eligible for funding from a particular grant-awarding body.
Applications, in the first instance, are always for the course in which you are interested. The procedure for obtaining finance follows after you have been accepted.
If you are not offered a grant, there are other possible sources of finance. These include institutional studentships, scholarships and awards, research assistantships, Career Development Loans and trusts and charities. Details are available in the Careers Service.
You could also consider studying part-time since this will spread the fee payment over a longer period and may enable you to support yourself through simultaneous employment.
