The above comments are really true. You can only afford for accomodation and your personal expences.If you are planning to extend your studies after one year, you need to have backing of your fees again from either Nepal or some other sources. But, if you are coming in post graduate courses with some paid intership program, then you can manage these, depending on your efficiency.
Please check other college too, there are range of college with different fee structure. Try to find the college which you can afford because there are range of university and college in UK.
