I did the SA cpl/ir and then converted to the JAR thing.
For the SA cpl you will have to do their cpl exams and then their flight training and flight tests.
On your return to the UK to convert to the JAR cpl/ir, you will have to do hours neccessary to pass the flight tests, ie. however many you take for the school to be happy to sign you off for the flight tests.
All round, expensive!
