Do I need a licensed electrician in Singapore

For electrical installation work in Singapore, yes. Electrical work is regulated and should be carried out by a licensed electrical worker. Beyond the legal position, unlicensed work on fixed wiring is the kind that shows up years later as a fault nobody can trace.

What actually happens

• Fixed-wiring work is regulated and should be done by a licensed electrical worker.
• Undocumented alterations are what make later fault finding expensive.
• Ask for the licence before work starts, not after.
