I have applied for more or less than same places as your self.
Manchester will admit people to the MEng, but if there perform poorly they get bumped on to the BEng and the same for the other way around. At least thats what the admissions tutor told me at my interview, which I got an offer at also.
Surrey told me to apply to the BEng and if I do well enough this year, they will put me on the MEng straight away.
