A family member wants to buy my house. He wants to rebuild everything except the garage. His bank (and the conveyancer?) insists on a CoC.

An electrician quoted me R8000 for the changes that he wants to make before issuing the CoC. Most of the changes relates to circuits that will be completely demolished (outside the garage).

I want to disable the circuits slated for demolition myself. Should I pull all the relevant wires out of the conduit, or is there a simpler way ?
