What Is an Electrical License in Singapore?
In Singapore, not everyone is allowed to work on electrical wiring. The law requires that only trained and licensed professionals carry out electrical work to ensure it is performed safely and correctly. This is managed through an electrical license Singapore, which guarantees that only qualified individuals handle power lines, sockets, lighting, and electrical panels in homes and offices. Ultimately, this licence protects families, buildings, and electrical systems from potential hazards or damage.
The Energy Market Authority (EMA) oversees who receives this licence. They issue it to workers who have completed the required training and demonstrate the knowledge to perform electrical work properly. These LEW licensed electrical workers install, inspect, and maintain systems carefully. EMA regulations ensure that homes are safe and that all electrical work complies with the law.
Why Electrical Licensing Matters
Electrical work needs more than plugging wires together. One wrong move may spark fires, fry circuits, or shut down power. So, Singapore follows strict rules to prevent that from happening. The rules guide workers and prevent mistakes before problems spread.
The electrical license in Singapore ensures workers:
Understand how to build and repair systems
Pick the right parts and tools
Follow all safety steps without skipping
Guard homes, offices, and schools from electrical trouble
These rules reduce accidents and keep everyone safe around electricity.
Who Are LEW Licensed Electrical Workers?
A LEW licensed electrical worker earns their licence from the EMA after completing the required training in handling electrical systems. They undertake tasks appropriate to their training and licence level, learning codes, diagrams, and safety procedures to ensure power flows safely and efficiently. These professionals diagnose problems quickly and carry out electrical work with care and expertise.
They don’t guess they know exactly what to do. Each job is planned with purpose, focus, and confidence. The EMA classifies workers into three main categories:
1. Electrician (Grade 7)
These LEW licensed electrical workers handle smaller jobs, such as wiring rooms, repairing lights, and inspecting outlets. They primarily work in homes or small shops, carrying out basic tasks with precision and the right tools.
Power limit: Up to 45kVA
Voltage: 1,000V and below
Their work ensures that homes remain safe and that electrical systems operate reliably.
2. Electrical Technician (Grade 8)
These LEW licensed electrical workers handle larger-scale projects than electricians. They install systems in places such as food courts, offices, and other busy buildings, and they design systems that comply with safety regulations.
They carefully plan circuits and review safety measures to ensure everything is secure.
Design work: Up to 150kVA
Operation work: Up to 500kVA
Voltage: 1,000V and below
Their expertise allows them to manage power safely in public and commercial spaces.
3. Electrical Engineer (Grade 9)
Engineers manage major tasks in tall buildings, factories, and large sites. They map out, install, and fix powerful electrical systems.
They organise large jobs and guide teams through complex projects.
No power limit
Voltage up to 400,000V, based on license
They keep power running smoothly across large systems and buildings.
When Do You Need a LEW Licensed Electrical Worker?
All electrical work in Singapore, regardless of scale, must be carried out by a LEW licensed electrical worker. This is required by law to prevent violations and protect homes, offices, and commercial buildings from potential hazards. Always ensure the worker has the correct licence class for the task.
Grade 7 Electrician: Suitable for home repairs
Grade 8 Technician: Suitable for offices or shops
Grade 9 Engineer: Suitable for large buildings or factories
Each class performs work according to their training, power capacity, and site size. Allowing unlicensed individuals to handle electrical work is both dangerous and illegal. Protect your property by hiring the right licensed professional every time.
How Can You Check a Worker’s License?
All LEW licensed electrical workers carry a card. It shows:
Name
ID number
License number

This card proves they finished training and earned approval from EMA. Before work starts, visit the EMA website and use their License Search Tool. This helps you check if the license is real. Always check before work begins to stay safe and avoid problems.

Assessment Steps
After training, the worker must:
Finish a 2.5-hour written test
Pass a 1-hour practical test
Complete a 1-hour interview with questions
