SAH Loans insist on using their own contractors to replace burst geysers etc. Do not just accept that these contractors are working as per regulations. Geyser connection and earthing must be done by an electrician (as per Kwikot). All plumbers know this. IOPSA will confirm. SAH replaced the geyser of a friend. It took a very strongly worded letter from me, quoting the regs, and a posting on "Hello Peter" to be forwarded to them before they finally sent "their" electrical contractor to reterminate the geyser and earth and bond the water-pipes as per code. The plumber's defence: "The previous guy never earthed the pipes".
Be aware, they have only their own interests in mind. So what if you get electrocuted.
