How can I find out the commission rates for agents recruiting international students to the UK? Problem

In the UK, higher education providers often work with third parties called international agents to recruit international students.

In this system, an international student may request advice from an international agent. If they place that student with their client university, they gain a commission.

My problem is that I do not know whether my university is offering a decent enough incentive to international agents for them to promote us over their other clients.

What I've tried so far

To find out how much commission agents receive, I've tried:


Launching a survey on a LinkedIn group for higher education international recruitment specialists. This has had no responses
Googling the question, but I haven't found any suitable results
Searching on job boards, but the positions are often not advertised, as many international agent companies are small family-owned businesses


My question

This is a bit of a left-field question, but how can I find the commission rates for international agents when they recruit for rival universities?
Make a Freedom of Information Act request.  Anyone can do this.  If you are concerned about possible charges, state that you would like to be given an estimate of any charges that would be incurred prior to them doing the work (photocopying, etc.).
