Licensed Electrician in Johannesburg
Electrical installations, repairs, and safety compliance
Professional Electrical Services
Sinqobile Construction provides licensed electrical services across Johannesburg and Gauteng — from new installations and rewiring to fault-finding, repairs, and electrical compliance certificates (COC). Our electricians are registered with the Department of Employment and Labour and work in accordance with SANS 10142-1 (the wiring code for South Africa). Whether you need a full house rewire in Bryanston, a DB board upgrade in Sandton, or an electrical COC for a property sale in Midrand, our team delivers safe, code-compliant electrical work. Electrical installations are regulated for good reason — faulty wiring causes fires and electrocution. We never cut corners on circuit protection, cable sizing, or earth bonding. Every job is tested with calibrated instruments and documented. Standard electrician rates in Johannesburg range from R300–R600 per hour in 2026, with experienced electricians charging R600–R800/hr for complex work.
Service Statistics
Our Electrical Services
Electrical Installations (New Build & Renovation)
Complete electrical rough-in and fit-out for new homes, extensions, and renovations. DB board installation, circuit wiring, plug points, light points, geyser connections, stove connections, and outdoor lighting. All installations comply with SANS 10142-1 and are tested before handover.
Electrical COC Certificates
Electrical Certificate of Compliance inspections and certificates as required when selling a property, changing ownership, or after new installations. We inspect the DB board, earth leakage protection, cable sizing, plug points, and general safety. COC certificates cost R850–R2,750 in Johannesburg depending on property size. Same-day certificates available for compliant installations.
DB Board Upgrades
Replacing old fuse boards with modern circuit breaker distribution boards, adding earth leakage protection (RCD/ELCB), and splitting circuits to meet current load requirements. Essential for older homes that were wired for lower electrical demands. DB board upgrade costs R3,000–R8,000 depending on the number of circuits.
Fault Finding & Repairs
Tripping circuits, flickering lights, dead plug points, and intermittent faults diagnosed with insulation resistance testing, earth loop impedance testing, and thermal imaging. We locate the fault, explain the cause, and repair it properly — no guesswork, no temporary fixes.
House Rewiring
Full or partial rewiring of older homes with outdated or unsafe wiring (typically pre-1980s installations with cloth-insulated cable or no earth wiring). Rewiring a typical 3-bedroom house costs R20,000–R30,000 and includes a new DB board, all new circuits, plug points, light points, and a COC on completion.
Outdoor & Security Lighting
Garden lighting, security floodlights, motion-sensor lights, gate motor connections, and electric fence installations. We design lighting layouts for security coverage and aesthetic effect, using energy-efficient LED fittings throughout.
Electrical Cost Guide — Johannesburg 2026
Electrical costs depend on the scope of work, cable runs, number of points, and whether the installation is new or a retrofit. All quotes include materials, labour, testing, and a COC where applicable. No hidden call-out fees.

Our Electrical Process
We follow a proven process to ensure quality results every time
Assessment & Quote
We inspect the existing installation (or review plans for new work), identify the scope, and provide an itemised quote with material specifications. For COC inspections, we assess on-site and advise immediately.
Installation / Repair
Our electricians complete the work according to SANS 10142-1 standards. We use quality materials from established suppliers and label all circuits clearly at the DB board.
Testing & Certification
Every installation is tested with calibrated instruments — insulation resistance, earth continuity, loop impedance, and RCD trip time. We issue a COC for all new installations and can issue one for existing compliant installations.
Handover & Documentation
You receive a test certificate, circuit schedule, and COC where applicable. We explain the installation, show you the DB board layout, and demonstrate any new switches or controls.
Frequently Asked Questions — Electrical
How much does an electrical COC cost in Johannesburg in 2026?
An electrical Certificate of Compliance (COC) in Johannesburg costs R850–R2,750 in 2026, depending on property size, number of DB boards, and installation complexity. A standard 3-bedroom home with one DB board is typically R850–R1,500. Larger properties with multiple boards or complex installations cost more. If the installation fails the inspection, repair costs are charged separately. We provide same-day COC certificates for compliant installations.
Do I need an electrical COC when selling my house?
Yes. South African law requires a valid electrical Certificate of Compliance (COC) when selling a residential property or changing ownership. The COC confirms that the electrical installation complies with SANS 10142-1 safety standards. The seller is responsible for obtaining the COC and paying for any repairs needed to achieve compliance. A COC is valid for 2 years from the date of issue.
How much does it cost to rewire a house in Johannesburg?
Rewiring a typical 3-bedroom house in Johannesburg costs R20,000–R30,000 in 2026. This includes a new DB board with circuit breakers and earth leakage protection, new cable on all circuits, new plug points and light points, and a COC on completion. Larger homes or those with difficult access (concrete walls, inaccessible ceilings) cost more. We provide a detailed quote after inspecting your existing installation.
Why does my DB board keep tripping?
The most common causes of tripping circuit breakers are: overloaded circuits (too many appliances on one circuit), a faulty appliance drawing excessive current, moisture in plug points or junction boxes, and degraded cable insulation causing earth leakage. Our electricians use insulation resistance testing and earth loop impedance testing to identify the exact cause. We then repair the fault and, if necessary, split overloaded circuits to prevent future tripping.
What is the difference between a circuit breaker and earth leakage?
A circuit breaker (MCB) protects against overload and short circuit — it trips when too much current flows through the cable. An earth leakage device (RCD/ELCB) protects against electrocution — it trips when current leaks to earth, which happens when you touch a live wire or a faulty appliance has an earth fault. Both are legally required in South African installations. Your DB board should have an earth leakage device protecting all circuits, plus individual circuit breakers sized for each circuit.
