Electrical pricing in Johannesburg is opaque, and that is exactly how some operators like it. Here are honest 2026 price ranges for the most common electrical services in Sandton and Northern Johannesburg, what drives the cost, and how to make sure you are comparing like with like. All figures are indicative — every job should be quoted in writing on site.
Electrical Certificate of Compliance (COC)
A residential Electrical COC inspection runs roughly R850–R2,750 depending on the size of the property and the state of the installation. If the inspection finds non-compliances (a common one is missing earth bonding or an over-loaded DB board), the remedial work is quoted separately. A COC is legally required for property transfer and is often a condition of insurance.
Fault finding and callouts
"No power" or a tripping earth leakage is usually a diagnostic job, not a fixed price. Expect a callout plus diagnostic time of around R650–R1,200 for a standard residential fault. Faults that trip intermittently — the classic "it trips when it rains" — need proper insulation-resistance testing to isolate the circuit, which takes longer but saves you replacing the wrong thing.
DB board upgrades
Older homes often have under-spec distribution boards that cannot safely carry modern loads (geysers, ovens, EV chargers, inverters). A compliant DB-board upgrade with surge protection and proper labelling typically runs R3,500–R12,000+ depending on the number of circuits and whether the board is being relocated. This usually includes a fresh Electrical COC.
Solar and inverter systems
The biggest-ticket items, and where quotes vary most. As a 2026 guide, installed: a 5kW hybrid with 5kWh battery from ~R110,000 (covers essentials and load-shedding), an 8kW with 10kWh from ~R165,000 (full-house by day, all-night backup), and a 12kW with 15kWh from ~R235,000 (off-grid capable). See solar power and inverter installations for what is included. Cheaper quotes often omit the DB-board changeover, surge protection or the COC.
Backup power (without solar)
If you only want to ride out load-shedding, an inverter and battery is cheaper than a full solar system. A right-sized battery backup for essential loads (lights, Wi-Fi, fridge, TV) is a fraction of a full PV install — the key is sizing it to your real essential load, not over-selling you capacity you will not use.
What makes prices vary
- Brand: tier-1 panels and reputable inverters (Sunsynk, Deye, Victron) cost more but last and carry real warranties.
- DB-board condition: a tidy, compliant board is quick to work on; a dangerous one adds remedial cost.
- Access and roof type: tile roofs and double-storey work take longer than face-brick single storey.
- Compliance: a proper COC and SSEG registration are part of a real quote, not extras.
How to avoid being overcharged
Get an itemised written quote before work starts, confirm the electrician is registered and will issue an Electrical COC, and check that DB-board work and compliance are included — not bolted on later. For businesses, the same rules apply to commercial electrical work and maintenance contracts.
