Naeem, you write that you are "in the UK". how long have you been in the UK already?
you see, you are not quite correct about the research councils. for them, nationality is only secondary. if you have been "normally resident" in the UK for three years, (and have "indeterminate leave to remain", that is, have "settled status"), then you are eligible for research council funding, no matter what your nationality is. so i'd suggest you make sure you know exactly if you are eligible or not.
other funding might be available from the scheveningen foundation, and from specific university departments, and from your home country. most universities have lists of potential funders, and you should also check out http://www.educationuk.org/scholarships/
it's your education. it's you who needs to do the research!
good luck!
