The initial deposit for Heriot-Watt University varies by program and student status. For most taught postgraduate programs, the deposit is typically £1,500 for international students and £500 for UK/EU students. However, Erasmus Mundus Masters programs often have different financial arrangements, and the university explicitly states that no commission is paid for these programs. Prospective students should verify the exact amount with the admissions office or the program coordinator, as fees and deposits may change annually.
