Completely, and utterly, illegal, not even to mention fraudulent. Whom ever gave you that certificate, should have his license revoked, not that it would solve anything in terms of what is wrong with this industry though....
Yep. When buying a house (as it is the sellers responsibility), you don't really have a choice in the matter as to who they use. When you own the property, you are ultimately responsible though, and therefore, can get the electrician of your liking.
You get mechanics, and then you get mechanics. You get ISPs, and then you get ISPs. You get electricians, and then you get electricians....
A sparkie asking you R300 for a COC and quickly spends an hour or two at your property, is not worth the paper he's certificate is written on.
The sad fact of the matter, is that these sparkies does not get REPORTED to the ECB, and therefore, they happily continue to do their shady work. Hell, if you know who to call, you can get a COC in exchange for a bottle of brandy. Until the PUBLIC takes responsibility, and REPORT these idiots to the ECB, nothing will ever change I suppose.
