Which part is not correct?
I have only ever paid cash to a consultant, and Ive seen plenty of them, privately, in plenty of different places.
If I have ever gone back to a GP to be referred to a different consultant because I wasnt happy with the first consultant I have been charged 60 quid by the GP.
What you are suggesting is, 60 quid for the first referral letter from the GP, cash. Anywhere from 150-250 quid, cash for the consultant. If not happy with the consultant, back to GP, another 60 quid, cash. Then another consultants fee.
Not many of us can afford the above you know - its not a solution.
