Because you can drive a motor car does not mean you can legally drive. In the same way just because you have a qualification in plumbing does not necessarily mean you can do plumbing work and or, more importantly, that you are complying with the respective South African National Standards and regulations. Your qualification merely denotes that you have met the requirements at a point in time. The PIRB process including that of the PIRB CoC and CPD denotes ongoing checks and balances of you as a professional. Only PIRB Licensed plumbers can issue PIRB CoC. Licensed plumbers have not only met the prescribed requirements of PIRB registration but have undertaken and passed the required PIRB assessment. Furthermore, licensed plumbers have maintained their prescribed 25 CPD points throughout their registration cycle.
