As EV adoption grows in Malaysia, more homeowners are installing chargers at home.
But alongside this growth, there’s also a rising concern:
Not all EV charger installers are properly licensed or qualified.
Some may offer cheaper pricing. Others may promise faster installation.
But here’s the critical question:
What are you actually risking by choosing an unlicensed installer?
1. EV Charger Installation Is Regulated in Malaysia
This is not optional or “recommended practice.”
It is a legal requirement.
According to Suruhanjaya Tenaga (Energy Commission):
- EV charging system installation must be carried out by a competent person
- Work must comply with established electrical standards and safety requirements
Who is considered a “licensed” installer?
In practical terms:
- A registered electrical contractor
- With certified personnel such as:
- Wireman
- Chargeman
- Professional Engineer (where applicable)
What this means:
If your installer does not meet these criteria:
The installation may not be compliant with Malaysian regulations
2. What Happens If You Use an Unlicensed Installer?
Many homeowners assume:
“If it works, it’s fine.”
This is a dangerous assumption.
Risk 1: Electrical Safety Hazards
EV charging involves:
- High current (up to 32A or more)
- Long duration (hours of continuous load)
Without proper design:
- Cables may overheat
- Connections may degrade
- Protection devices may not trip correctly
Result:
- Fire risk
- Equipment damage
- System instability
Risk 2: No Proper Protection Design
Guidelines require:
- Overcurrent protection (MCB / MCCB)
- Earth leakage protection (RCCB ≤30mA)
- Dedicated circuit design
An unlicensed installer may:
- Skip RCCB installation
- Use incorrect ratings
- Share circuits with other appliances
Result:
- Increased risk of shock
- Undetected leakage current
- System overload
Risk 3: Warranty Issues
Most EV charger manufacturers (including reputable brands) require:
- Installation by qualified personnel
- Compliance with standards
If not:
- Warranty may be voided
- Claims may be rejected
Risk 4: Insurance Complications
In the event of:
- Fire
- Electrical failure
Insurance providers may investigate:
- Was the installation compliant?
- Was a licensed contractor involved?
If not:
Claims can be disputed or rejected.
Risk 5: Hidden Long-Term Costs
Cheap installation often leads to:
- Frequent tripping
- Cable degradation
- Need for reinstallation
Reality:
You may end up paying more than doing it properly from the start
3. Why Unlicensed Installers Can Offer Lower Prices
This is important to understand.
They typically save cost by:
- Skipping proper assessment
- Using undersized cables
- Omitting protection devices
- Reducing labour time
- Avoiding compliance requirements
What you don’t see:
- Increased risk
- Reduced lifespan
- Lack of accountability
4. How to Verify a Licensed EV Charger Installer
Before proceeding, ask for:
1. Company credentials
- Registered electrical contractor status
2. Competent person details
- Who is responsible for the installation?
3. Scope of work
- Is it compliant with EVCS guidelines?
4. Protection design
- What MCB and RCCB will be used?
A professional installer will:
- Answer clearly
- Provide documentation
- Explain their design
5. Real Difference: Professional vs Unlicensed Installer
| Aspect | Licensed Installer | Unlicensed Installer |
| Compliance | Meets ST guidelines | Uncertain |
| Safety design | Engineered | Basic / unclear |
| Protection devices | Properly selected | Often minimal |
| Testing | Conducted | Often skipped |
| Accountability | Clear | Limited |
6. The Bigger Picture: Your Home Is at Stake
Your EV charger is not installed in isolation.
It is connected to:
- Your home wiring
- Your distribution board
- Your entire electrical system
A poor installation affects:
- Your appliances
- Your power stability
- Your family’s safety
7. Why This Matters More in Malaysia
Malaysia has unique conditions:
- High ambient temperatures
- Mix of old and new electrical systems
- Predominantly single-phase homes
- Increasing EV adoption without infrastructure upgrades
This makes proper installation even more critical.
Final Thoughts
Choosing between a licensed and unlicensed EV charger installer is not just about price.
It is about:
Whether your installation is designed to handle high electrical loads safely, every day.
A licensed installer:
- Works within system limits
- Designs properly
- Protects your home
An unlicensed installer:
- May only focus on getting the job done
Bottom Line
If the installation is not compliant, it is not safe — even if it works today.
