What residential electricians handle
Residential electrical work in Johor Bahru covers everything inside and around a home's wiring system: new circuit installation for renovations, switchboard and consumer unit upgrades, lighting installation, socket and switch repairs, ceiling fan wiring, water heater point installation, earthing and trip-switch troubleshooting, and rewiring older terrace houses or apartments where the wiring no longer meets current load demands. Many electricians in this category also handle smaller jobs like fixing tripping breakers, replacing faulty sockets, or wiring outdoor lighting and gate motors. Some take on Suruhanjaya Tenaga (ST) certified work, which matters for anything tied to your official electrical installation license or TNB supply approval.
What to check before you hire
Ask whether the electrician or their supervising wireman holds a valid Suruhanjaya Tenaga wireman's license (this is a legal requirement for most electrical work in Malaysian homes, not just a nice-to-have). Get a written quote that separates labour from materials, ask how they handle warranty on their workmanship, and check if they inspect the existing wiring before quoting rather than pricing blind over the phone. For bigger jobs like full rewiring, ask for a rough timeline and whether they coordinate with TNB if a supply disconnection is needed.
