Our Electrical Services in Singapore
DB Box (Distribution Board) Services
The distribution board (DB box or consumer unit) is the heart of your home's electrical system. AOT provides:
- DB box inspection and testing
- Faulty MCB (Miniature Circuit Breaker) replacement
- DB box upgrade to RCBO or RCCB protection
- New DB box installation for renovation or extension
- Earth leakage protection testing
In Singapore, EMA requires that DB boxes in HDB flats meet current safety standards. If your DB box is over 15 years old or keeps tripping, it may need an upgrade. AOT can assess and advise.
Power Sockets & Switches
We install, repair, and replace:
- Single and double power sockets (13A)
- USB charging sockets
- Light switches (single, double, dimmer)
- Extension socket panels
- Weatherproof outdoor sockets
All socket work uses BS 1363-compliant fittings approved for Singapore's electrical system.
Lighting Installation & Repairs
From LED downlights and pendant lights to track lighting and feature walls, AOT handles all lighting installation. We also replace faulty ceiling fans, repair flickering lights, and install smart home lighting systems.
Electrical Wiring & Re-wiring
Older Singapore properties (especially those built in the 1970s–80s) may have ageing PVC-insulated wiring that has degraded over time. Signs of old or faulty wiring include frequent circuit trips, discoloured sockets, burning smell, or buzzing sounds. AOT provides partial and full re-wiring services, including concealed wiring in conduit.
Water Heater Electrical Works
Installing a new water heater often requires a dedicated circuit from the DB box. AOT coordinates both the electrical and plumbing aspects of water heater installation — you only need to call one contractor. Learn more: Water Heater Installation Singapore.
Air-Con Electrical Works
Aircon installation or upgrade often requires new isolator switches, dedicated wiring, and DB circuit additions. Our electricians work alongside our aircon technicians for a seamless experience.
Fault Finding & Testing
Intermittent faults — lights flickering, sockets sparking, MCBs tripping — can be hard to track down. AOT uses professional test equipment (insulation resistance testers, loop impedance testers) to diagnose and resolve electrical faults accurately.
EMA Licensing & BCA Compliance
In Singapore, all electrical installation work on fixed wiring (anything beyond changing a light bulb) must be carried out by a Licensed Electrical Worker (LEW) registered with the Energy Market Authority (EMA). Work done by unlicensed individuals is illegal, voids insurance, and can result in dangerous situations.
AOT employs EMA-licensed LEWs and maintains all required certifications. For works requiring an Electrical Installation Licence (EIL) or EMA notification, we handle the paperwork on your behalf.

FAQs — Electrician Singapore
Do I need a licensed electrician for socket repairs in Singapore?
Yes — any work on fixed electrical installations (sockets, switches, wiring, DB box) must be done by an EMA-licensed electrical worker. DIY electrical work is illegal in Singapore and voids your home insurance.
How do I know if my wiring is unsafe?
Signs include: frequent MCB/ELCB trips, burning smell from sockets, discoloured or cracked switch plates, buzzing/humming from walls, or lights that flicker. If you notice any of these, contact AOT for an inspection.
Can AOT do electrical work during HDB renovation?
Yes. AOT works with HDB renovation requirements including submitting Electrical Installation Licence (EIL) paperwork where needed. We coordinate with your ID and other contractors for smooth project delivery.
What is the difference between an MCB and RCBO?
An MCB (Miniature Circuit Breaker) protects against overloads and short circuits. An RCBO (Residual Current Breaker with Overcurrent protection) provides additional protection against earth leakage — reducing the risk of electrocution. Modern Singapore homes should have RCBO protection on key circuits. AOT can upgrade your DB box accordingly.
