FAQ

Common Questions About Electrical Wiring

How much does full house rewiring cost in Kuala Lumpur?
Full house rewiring costs vary depending on property size and complexity. As of 2026, a typical 3-bedroom house in KL ranges from RM3,000 to RM8,000. We provide free on-site assessments to give accurate quotes based on your specific property.
What is the difference between concealed and surface wiring?
Concealed wiring runs inside walls and ceilings for a clean look, while surface wiring is mounted on walls. Concealed is preferred for new builds and renovations for aesthetics, surface is used where walls cannot be disturbed. Both comply with Suruhanjaya Tenaga standards.
How long does house rewiring take?
A typical 3-bedroom house rewiring takes 3-5 days for a complete rewire, including testing and certification. Larger properties or commercial installations may take longer. We work efficiently to minimise disruption to your daily routine.
Do I need to move out during rewiring?
In most cases, you can remain in your home during rewiring. We work room by room and take precautions to keep your home safe and functional. We'll discuss the schedule with you beforehand so you know what to expect.
What is the wire colour code in Malaysia?
Malaysian wiring follows the modern colour standard: brown for live, blue for neutral, and green-yellow for earth. Older homes may still use the legacy system of red (live), black (neutral), and green (earth). If your property has old colour-coded wiring, a rewire ensures compliance with current Suruhanjaya Tenaga standards.
What do L1, L2, and L3 mean in electrical wiring?
L1, L2, and L3 refer to the three phases in a 3-phase power supply, commonly used in commercial and industrial properties in Malaysia. Each phase carries alternating current at a different timing. Most residential homes use single-phase (L1 only), while factories and large offices use 3-phase for heavier electrical loads.
