Electrical License in Singapore: Why It Matters for Installation & Maintenance Services

When dealing with electrical work in Singapore, it’s important to know that you cannot hire just anyone. The law is strict: only a LEW licensed electrical worker can install, repair, test, or maintain electrical systems. This ensures that homes, offices, shops, and large sites are protected from electrical risks.

Below, you will learn why the electrical license in Singapore matters, what LEW workers actually do, and why you should always hire one for any electrical job.

What Is an Electrical License in Singapore?

An electrical license in Singapore is a legal approval issued by the Energy Market Authority (EMA). It allows a trained professional to carry out electrical work safely and in compliance with the law.

A LEW licensed electrical worker has the skills to handle wiring, lighting, power points, circuits, panels, and main systems. Because electrical work is risky, the EMA ensures that each worker is properly trained before issuing a licence.

The licence shows that the worker:

• Understands electrical codes

• Uses proper tools

• Follows safety rules

• Works without causing damage

• Knows how to prevent shocks, fires, or power faults

Hiring someone with an electrical license in Singapore helps protect your property and everyone inside it.

Why the Electrical Licensing System Matters

Electrical systems look simple from the outside. Yet one wrong connection can cause a fire or even a power outage in a whole building. This is why licensing matters.

A LEW Keeps You Safe

A licensed worker understands how electricity behaves. They know how to install and fix systems without putting anyone at risk. Because of this, they reduce the chance of accidents.

A LEW Prevents System Failures

Most electrical issues are caused by poor workmanship. When a trained worker handles your system, you avoid faults such as:

• Flickering lights

• Overloaded circuits

• Burnt wiring

• Tripping breakers

A LEW Ensures the Work Is Legal

Singapore law requires a LEW licensed electrical worker for almost all electrical work. Hiring an unlicensed person is not only unsafe but can also result in legal penalties.

A LEW Helps You Avoid Costly Repairs

Correct work done the first time saves money. You do not need to pay for repeat repairs or major fixes later.

Types of LEW Licensed Electrical Workers

EMA groups LEW professionals into three grades. Each grade covers a different level of responsibility and power capacity.

Grade 7 — Electrician

A Grade 7 Electrician handles basic electrical work such as:

• Installing lights

• Replacing switches

• Fixing power points

• Wiring small rooms

Power limit: Up to 45kVA

Voltage: 1,000V and below

These workers usually support homes and small shops. They keep small electrical systems running safely.

Grade 8 — Electrical Technician

A Grade 8 LEW handles larger jobs. They work on electrical systems in:

• Offices

• Food courts

• Retail units

• Mid-sized commercial spaces

Their work includes designing circuits, planning layouts, and checking safety rules.

Design work: Up to 150kVA

Operation work: Up to 500kVA

Voltage: 1,000V and below

They make sure power is stable in busy areas with higher demand.

Grade 9 — Electrical Engineer

A Grade 9 Engineer oversees major electrical systems. They handle installation and maintenance work for:

• High-rise buildings

• Industrial plants

• Factories

• Large commercial sites

Because these places use a lot of power, the engineer must plan and manage the entire system.

Power limit: No limit

Voltage: Up to 400,000V (based on licence)

They guide teams, inspect complex systems, and ensure everything is safe and compliant.

When Do You Need a LEW Licensed Electrical Worker?

In Singapore, all electrical work must be carried out by a LEW licensed electrical worker. This rule is strict and non-negotiable. If the job involves wiring, circuits, or power systems, you must hire a licensed professional.

Use this guide:

• Grade 7 Electrician: Home repairs or small shops

• Grade 8 Technician: Offices, small buildings, and commercial spaces

• Grade 9 Engineer: Large buildings, factories, and projects with high power demand

Because each grade has different authority, choosing the right LEW ensures the work is safe and legal.

How to Check if a Worker Has an Electrical Licence

Every LEW carries an EMA-issued licence card. It shows:

• Name

• Photo

• ID number

• Licence number

• Grade

Before any work begins, you can verify the licence using the EMA Licence Search Tool. This confirms that the LEW licensed electrical worker is certified and authorised to carry out the job.

Taking this step protects you from scams and unlicensed workers who could cause damage.

What LEW Services Usually Include
