Commercial Electrical Services in Sandton & Northern Johannesburg

Downtime is expensive. A tripping DB board, a failed three-phase supply or a load-shedding gap can stop trading, spoil stock or send staff home. Apple Plumbing & Electrical keeps offices, retail stores, warehouses and complexes across Sandton, Midrand and Northern Johannesburg powered and compliant. Our registered electricians provide planned electrical maintenance, fault finding, DB-board upgrades, backup power and the Electrical COCs your lease, insurer and the Department of Labour require — with one accountable contractor rather than a rotating panel of sub-trades.

What we do

Our commercial scope covers fault finding and reactive repairs, single- and three-phase DB-board upgrades, sub-metering and prepaid meters, emergency and exit lighting, energy-efficient LED retrofits, surge and lightning protection, and backup power (inverter, battery and generator changeover) sized to keep essential loads running. For facilities and store managers we run scheduled maintenance — thermal-imaging DB inspections, earth-leakage testing and compliance checks — that catch faults before they cause downtime or fail an inspection. Every job is documented and we issue Electrical Certificates of Compliance to current SANS 10142. We carry public liability cover and coordinate work around trading hours.

Why choose Apple Plumbing & Electrical

We're a registered electrical contractor with our registered electricians on every job — not a sales outfit that sub-contracts the work. That means correct load calculations, code-compliant DB work and a COC you can actually use for your lease and insurance. Because we also do plumbing in-house, geyser, pump and power issues are handled by one team.
