A few minutes later a couple of students showed up and after telling them what is wrong and how to fix it, they fixed it.
But the wiring is still a mess, the geyser is still not bonded and the steel structure of the house is not earthed. A legal COC, sloppy COC or faulty COC?!
2 points, I think, worth mentioning are: ( please correct me if I am wrong )

1) Lights not working does not invalidate a COC. Lights are fixed appliances and as long as the supply is good up to the terminals on the fitting, it passes the COC test.

2) Geyser bonding: As long as continuity can be proven by the test described in 8.6.2 then no external bonding conductors are required.

8.6.2 Continuity of bonding

Test the continuity of the bonding between the consumers earth terminal and all exposed conductive parts using a supply that has a no-load d.c. or a.c. voltage of 4 V to 24 V and a current of at least 0,2A. In each case, the resistance shall not exceed 0,2 Ohms.
