You will become liable to repay your student loans in the April after you complete your studies. This means that if you withdraw from University before April, then you may be liable to start making repayments in just a few months time. Remember that you only have to repay your student loans when you income is above £15,000 per year and if you are not earning that much then can defer your repayments. You can also defer your repayments if you decide return to your studies and start a new course.
