Electricians in Johannesburg — Get Payment-Protected Quotes

Johannesburg electricians offer a full range of services including home wiring and rewiring, distribution board upgrades, Certificate of Compliance (COC) inspections, data and network cabling, lighting installations, and fault-finding. With load shedding a persistent reality in Gauteng, many electricians now specialise in backup power solutions — inverter installations, automatic changeover switches, and solar integration. Data cabling has also become a high-demand service as more Johannesburg professionals work from home and need reliable network infrastructure. All electrical work must comply with SANS 10142 standards, and only a registered electrician can issue a COC. On Completo, electricians are verified against the Department of Employment and Labour registry before they can quote on your project.

The most effective load shedding solution is a hybrid inverter system with battery backup, which keeps essential circuits running during outages. A basic setup (3kVA inverter with a 5kWh lithium battery) costs R25,000–R45,000 installed and powers lights, Wi-Fi, a TV, and a laptop for 4–6 hours. For whole-home coverage, a 5kVA system with 10kWh of storage runs R60,000–R90,000. Your electrician will install an automatic changeover switch so the system kicks in instantly when Eskom drops. Pair this with a solar array and you can offset daytime electricity costs entirely. A qualified electrician should assess your distribution board first — older boards may need an upgrade before an inverter can be safely connected.

A COC is legally required in South Africa when selling a property, when a new tenant moves into a rental property, and after any new electrical installation or significant alteration. In Johannesburg, this is particularly relevant given the high volume of property transactions in suburbs like Sandton, Fourways, and Midrand. The inspection costs R850–R2,000 and checks earthing, bonding, circuit protection, wiring condition, and the distribution board. If faults are found, remedial work must be completed before the COC can be issued — this can range from R500 for a minor fix to R15,000+ for extensive rewiring. Only a registered electrician with a valid wireman's licence can issue the certificate.
