By law, the seller must provide the buyer with an electrical compliance certificate that covers the permanent electrical installation – this means everything from where the Eskom cables join the property up to the point where the cables end at the appliances (plug point, light fitting and the permanent connection at a stove, pool pump, air con unit or geyser). In other words, the actual appliances that run from these points do NOT form part of the compliance certificate, no matter whether they are temporary or fixed appliances.
Fixed appliances are those that run from the permanent connection point and will include the stove. This essentially means that you cannot expect a compliance certificate from the seller. However, since the stove is a fixed asset (it gets sold with the house) if you are concerned about its working condition, you are entitled to negotiate with the seller that they repair it before you sign the sale agreement. The seller should by law disclose any issues with fixed appliances to the interested buyers.
