Is Your Singapore Home's Electrical System Safe?
Singapore has one of the highest urban densities in the world — and with that comes significant stress on home electrical systems. Whether you live in a 20-year-old HDB flat or a newly built condo, electrical faults are one of the leading causes of residential fires in Singapore.
Alpha & Omega Trinity Pte Ltd — a BCA-registered M&E contractor — conducts comprehensive electrical safety audits for homeowners and property managers across Singapore. Here's what you need to know.
What Is an Electrical Safety Audit?
An electrical safety audit is a systematic inspection of all electrical components in your home, including:
- Distribution Board (DB Box) — check for overloaded circuits, tripping breakers, and outdated wiring
- Power Points & Sockets — identify loose connections, burn marks, or overheating
- Ceiling Fans & Light Fixtures — ensure correct wiring and earthing
- Air Conditioner Isolator Switches — check for correct amperage rating
- Water Heater Connections — verify correct earthing and RCCB protection
- Earthing & Bonding — confirm all metal parts are safely earthed
Why Do HDB Homes Need Electrical Audits?
Many HDB flats were built in the 1980s–1990s and have original electrical wiring that was not designed for modern appliances. Today's households run air conditioners, induction cookers, electric water heaters, smart TVs, and multiple EV chargers simultaneously — far exceeding the load capacity of older wiring.
Signs your home needs an electrical audit:
- Circuit breaker trips frequently
- Lights flicker or dim when appliances start
- Burning smell near sockets or the DB box
- Electric shocks when touching appliances
- Old or discoloured wiring in the ceiling or walls
- Power points feel warm to the touch
What Happens During an AOT Electrical Safety Audit?
Our BCA-registered licensed electricians follow a structured inspection protocol:
- Visual Inspection — all accessible wiring, outlets, switches, and the DB box
- Insulation Resistance Testing — use a megohmmeter to test wire insulation integrity
- Earth Continuity Testing — confirm all metalwork is safely earthed
- Load Testing — verify circuits are not overloaded
- RCCB/RCBO Function Testing — trip test all residual current devices
- Written Report — full findings with photos and recommended rectifications
How Much Does an Electrical Audit Cost in Singapore?
Alpha & Omega Trinity offers electrical safety audits from $120 for a standard 3-room HDB up to $350 for large condos or landed properties. This includes a written inspection report with photographic evidence.
Rectification works are quoted separately and only undertaken with your approval.
