swantje, as yours is a 1+3 award, i'm not sure about the criteria - but they will be along the lines of: your MSc course (the 1+ bit) being accredited by the ESRC; your supervisor fulfilling all necessary criteria, like, if he/she is new to supervising, the school would have to provide a second supervisor with more experience to you... things like that.
are you going to live in students' residences?
