When it comes to electrical work in Singapore—whether for HDB flats, offices, or industrial spaces—safety and compliance are top priorities. But many homeowners and business owners don’t realise that it’s illegal to carry out electrical works without proper EMA licensing.
If you’re hiring someone to fix your wiring, upgrade your DB box, or install a new power point, you must ensure they are licensed by the Energy Market Authority (EMA). This isn’t just about paperwork—it’s about protecting your property, your life, and avoiding legal trouble.
In this article, we’ll explain:
- What EMA licensing is
- Who needs to be licensed
- Why it’s important for safety and legal compliance
- How to verify if your electrician is EMA-certified
- Risks of hiring unlicensed workers
What is EMA (Energy Market Authority) in Singapore?
The Energy Market Authority (EMA) is the regulatory body overseeing Singapore’s electricity and gas sectors. Its key role is to ensure that energy systems are safe, reliable, and meet national standards.
In the context of electrical work, EMA regulates:
- Electrical licensing and certifications
- Safe electrical practices
- Energy supply system reliability
- Professional conduct of electrical workers
So, if someone is doing electrical installations or repairs in Singapore, EMA wants to make sure they are qualified, trained, and accountable.
What Is an EMA Licensed Electrical Worker (LEW)?
A Licensed Electrical Worker (LEW) is a person certified by EMA to carry out or supervise electrical works, including installation, maintenance, and testing. There are three classes of LEWs:
| Class | Scope of Work |
|---|---|
| Grade 1 | Design and operate high-voltage (HV) systems |
| Grade 2 | Operate and maintain HV/low-voltage systems |
| Grade 3 | Install and repair low-voltage systems (up to 1000V) — typically used in homes and small businesses |
For most residential and commercial projects, Grade 3 LEWs are the relevant professionals.
What Electrical Works Require EMA Licensing?
In Singapore, any electrical work beyond plugging in an appliance must be done by or under the supervision of an EMA-licensed electrician.
This includes:
- Rewiring homes or offices
- Installing DB boxes or circuit breakers
- Adding new lighting or power points
- Upgrading electrical load capacity
- Installing emergency backup systems
- Testing and certifying installations
By law, licensed electricians must also submit a Certificate of Compliance (COC) to EMA for certain installations.
🔎 Why EMA Licensing Matters
1. Ensures Electrical Safety
Licensed electricians are trained to:
- Use the right wiring and cable sizes
- Prevent overloads or short circuits
- Test and verify that your system is safe
- Follow updated electrical codes and standards
Improper work by unlicensed workers can lead to:
- Fires
- Electric shocks
- Damaged appliances
- Long-term system failure
2. Legal Compliance
Under the Electricity Act, it is illegal to:
- Perform or supervise electrical work without a licence
- Engage someone unlicensed to perform electrical work
Penalties include:
- Fines up to $5,000
- Imprisonment of up to 12 months
- Loss of insurance coverage in case of an accident
3. Required for Insurance & Renovation Approvals
If a fire or electrical incident happens, your home insurance provider may deny your claim if unlicensed work was performed.
Similarly, HDB and BCA renovation approvals often require proof that all electrical works were done by EMA-licensed workers.
4. Quality Assurance
Licensed electricians are held accountable for their work. They must:
- Submit proper documentation
- Offer warranties on installation
- Pass routine checks or audits
Unlicensed workers have no accountability—and you risk shoddy workmanship with no recourse.
What Is the Certificate of Compliance (COC)?
When an EMA-licensed electrician completes an installation (e.g., rewiring, upgrading DB box, or increasing load capacity), they must submit a Certificate of Compliance (COC) to EMA.
This confirms that:
- The work was carried out by a qualified person
- All electrical systems were tested and passed inspection
- Your home or premises is electrically safe to operate
You should always request a copy of the COC from your electrician upon completion of major work.
How to Check if an Electrician Is EMA Licensed
It’s easy to verify if your electrician is legitimate:
Step 1: Ask for the License Number
All EMA-licensed electricians have a unique LEW license number.
Step 2: Visit EMA’s Public Register
Search for the LEW’s name or license number at:

Step 3: Confirm Scope of Work
Ensure the electrician’s grade covers the work you’re requesting (Grade 3 for home and small business electrical work).
Real Risks of Using Unlicensed Electricians
You may be tempted to save money by hiring a freelance handyman or non-certified worker—but here’s what you risk:
| Risk | Consequence |
|---|---|
| Fire Hazards | Poor wiring can cause overheating and fire |
| Equipment Damage | Incorrect voltages can fry appliances |
| Safety Risks | Uninsulated wires may shock or electrocute |
| No Legal Recourse | Can’t file complaints against unlicensed workers |
| Invalid Insurance Claims | Home insurance may reject claims post-incident |
| HDB Renovation Issues | Approval may be delayed or revoked |
