Every HDB flat, office tower and factory in Singapore depends on safe electrical installations, and the law requires that the people who design, install, inspect and take charge of that work are properly licensed. If you enjoy hands-on technical work and want a career with a clear progression path, becoming a licensed electrical worker in Singapore is worth a serious look. This guide explains the licence grades, the usual route through qualifications, experience and exams, and how to plan your next steps.
Requirements are set and updated by the Energy Market Authority (EMA). Treat this as a general overview and check EMA’s website for the current rules before you sign up for any course or exam.
What an LEW Does and Why the Licence Matters
LEW stands for Licensed Electrical Worker. In Singapore, electrical installation work generally has to be carried out or supervised by an LEW, and many installations need an LEW to take charge of them, inspect them and certify that they are safe before they are switched on. For consumers, this is why they are advised to look for licensed help, as explained in our guide to finding a licensed electrician.
Typical LEW work includes:
- installing, extending and repairing wiring in homes, shops and offices;
- testing and inspecting installations and issuing the required certificates;
- taking charge of the electrical installations of larger buildings on an ongoing basis;
- designing installations for new buildings or major renovations at the higher grades.
The licence is personal. It shows that you have met EMA’s standard of knowledge and experience, and it comes with legal responsibilities. Doing licensable work without the right grade can lead to serious penalties.
The Three LEW Licence Grades
EMA licenses LEWs in three main grades. Each grade allows you to work on installations up to a certain size and voltage, and the higher grades also allow design work. The exact capacity limits and scope are set out by EMA.
| Grade | General scope | Typical background |
|---|---|---|
| Electrician | Smaller installations, such as homes and small shops | ITE-level electrical qualification plus practical experience |
| Electrical Technician | Medium installations, such as larger commercial premises | Diploma-level electrical engineering qualification plus experience |
| Electrical Engineer | Large and high-voltage installations, including design | Degree in electrical engineering plus substantial experience |
Within each grade, a licence may cover different types of work, such as installation, design or taking charge of an operating installation. Check which privileges apply to the licence you are applying for.
The Usual Route: Qualifications, Experience and Exams
While details differ by grade, most people go through the same three building blocks.
1. A recognised qualification
You will generally need an electrical qualification that EMA recognises for your grade. Common starting points are:
- ITE Nitec or Higher Nitec courses in electrical or related engineering fields, a frequent route to the Electrician grade;
- Polytechnic diplomas in electrical engineering, a common route to the Electrical Technician grade;
- University degrees in electrical engineering for the Electrical Engineer grade.
If you already hold an overseas qualification, EMA may assess whether it is acceptable. Do not assume it will be recognised without checking.
2. Relevant practical experience
EMA requires a period of relevant working experience in electrical installation work before you can be licensed. This is usually gained by working under the supervision of a licensed LEW, for example as an electrical tradesman, technician or junior engineer. Keep a careful record of your work, the installations involved and your supervisors, because you may need to document your experience in your application.
The required length of experience depends on your grade and qualification, so check EMA’s current requirements early and plan your first jobs around them.
3. Passing the required assessments
Most applicants must pass written examinations covering electrical theory, safety and Singapore’s electrical regulations and codes of practice. Some grades also involve an interview or oral assessment. Exam schedules, venues and formats are announced through EMA and the appointed exam bodies, so watch their notices and register in good time.
Building Your Career as an LEW
Getting the first licence is only the start. LEWs commonly progress in a few directions:
- Moving up a grade. With further study and experience, an Electrician can work towards the Electrical Technician grade, and so on. Many people study part-time while working.
- Specialising. Areas such as building services, solar installations, electric vehicle charging and industrial plants all need LEWs with specific know-how.
- Running your own firm. Some LEWs go on to set up an electrical contracting business. That brings extra licensing and business requirements, covered in our guide to starting a plumbing or electrical services business.
- Taking charge of buildings. Facilities management companies need LEWs to take charge of installations in malls, offices and estates.
Your licence must be renewed regularly, and EMA may set conditions on renewal. Keep up with changes to codes and standards, and consider courses that keep your skills current.
Is This Career Right for You?
Ask yourself honestly:
- Do you enjoy practical problem-solving? Much of the work is diagnosing faults and getting things working safely.
- Are you careful and methodical? Electrical work leaves little room for shortcuts.
- Can you handle physical work? Many jobs involve climbing, crawling into ceilings and working in hot plant rooms.
- Are you prepared to keep studying? Progression depends on further qualifications and exams.
If you answered yes to most of these, try to get some exposure first. Internships during ITE or polytechnic, or a holiday job with an electrical contractor, will tell you a lot about day-to-day life on site.
Practical First Steps
- Read the LEW section of the EMA website and note the requirements for the grade you are aiming for.
- Choose a course that clearly leads to that grade, and ask the school how past graduates have gone on to qualify.
- Look for a first job where you will work under an experienced LEW and log recognised experience.
- Start reading Singapore’s electrical codes of practice early, as they form a large part of the exams.
- Talk to working LEWs about their path. Most are happy to share how they got there.

Frequently Asked Questions
How long does it take to become a licensed electrical worker? It depends on your grade, qualification and the working experience EMA requires, so there is no single answer. The route combines a recognised qualification, a period of supervised experience and written assessments. Check EMA’s current requirements early and plan your first jobs around them.
Can I become an LEW with an overseas electrical qualification? Possibly, but do not assume it will be accepted. EMA may assess whether an overseas qualification is recognised for the grade you want. Check with EMA before enrolling in any course or exam, and keep records of your coursework and work experience ready.
What is the difference between an electrician and an electrical engineer licence? The grades differ in the size and voltage of installations you may work on. Electricians handle smaller installations such as homes and small shops, while Electrical Engineers deal with large and high-voltage installations and can do design work. EMA sets the exact limits.
What can I do while gaining experience if I am not yet licensed? You can work under the supervision of a licensed LEW, for example as an electrical tradesman, technician or junior engineer. Keep a careful record of your work, the installations involved and your supervisors, because you may need to document this in your application.
Is being an electrician physically demanding in Singapore? Often, yes. Many jobs involve climbing, crawling into ceilings and working in hot plant rooms, and the work leaves little room for shortcuts. If you are unsure, try an internship during ITE or polytechnic, or a holiday job with an electrical contractor, to see site life first.
