How do your universities contract external consultants?

In the #UK, I have come across 2 ways: 1. a range of external consultancy contracts between the #HEI (Higher Education Institute) and the consultant; 2. an intermediary agency that liaises between the HEI and the consultant, whereby the agency presumably receives a fee for handling the the contractual arrangements.
