Interesting to bring this up; I've heard that one should never ever put 'References available upon request' on your CV, but always give the contact details/position of your referees. Because the company won't want to contact you again to get more details they should already have in order to contact your referees. Ash states that 'referee reports' are included, so I would suspect those would be the actual reference given by the referee, rather than referee themselves.
For us, applicants are asked to provide name and contact numbers of the referees on the submission sheet, but also the completed referee report (another form completed by the person giving the reference for the applicant).
Nine times out of 10, we will get the referee names and phone numbers, with no written reports.
There are a couple of issues, in that people in private enterprise can actually put their current job at risk if they ask their boss for a reference, and I'm sympathetic to this. I generally commit to applicants that, unless they are really in the running for the job, I won't contact the referees. I also prefer doing verbal reports (calling the referee), because referees are generally more likely to tell you stuff. Even though everything they say gets written down and sent to the referee for signoff, and then goes to the applicant.
