Gauteng cost guide · Updated 27 August 2026
A basic single-phase manual changeover-switch installation starts from about R3,200 where the board is accessible, the selected switch suits the supply and only a short standard connection scope is required. The generator, inlet arrangement, extended cabling, enclosure changes and corrective work are separate. The design must prevent unsafe back-feed and account for the neutral and earthing arrangement.
This is planning guidance. The final amount depends on the written scope, access, condition, materials, timing and work found necessary. Never treat a search-result price as a property-specific quotation.

Why prices move
A better quote explains the variables instead of hiding them inside one number.
Automatic transfer and control equipment is substantially different from a manual changeover.
Three-phase supplies need correctly rated multi-pole equipment and a different design scope.
Distance, cable size, containment, weather exposure and inlet position affect materials and labour.
Separating priority circuits can require a sub-board or DB-board reconfiguration.
Before you approve

Questions people ask
It separates utility and generator sources so the installation cannot feed electricity back into the network or connect sources incorrectly.
No. The starting figure covers a basic changeover installation basis only; the generator and its accessories are separate.
No. Improvised back-feeding is dangerous and can expose occupants and utility workers to live conductors.
Only if the generator, wiring and design support the load. Many properties use a selected essential-load arrangement.
Electrical additions or alterations must be inspected, tested and appropriately certified for their scope.
