I take exception Buenchito to referring to my answer as rubbish.
To try to throw some further light on this rather complex subject I will try to give you some hard facts.
Firstly in a properly regulated area if a taximeter is fitted to the vehicle then it MUST be used for any journey commencing and terminating within that area.
If no meter fitted then it is fare by agreement PRIOR to the commencement of the hire.
I don't know where this business is located, but I presume there is some form of control,as you said that your friend has passed a topographical test. This test is not normally required for a private hire licence,only being a necessity for a taxi.
The best thing that your friend could do is to contact whoever has issued this licence and see what terms and conditions apply locally.
I can assure you that despite a previous poster 's remarks Local Authorities do set fares for PHC cars working in their area,as described above.
