How to Choose a Good Electrician (LEW Checklist)

A Singapore homeowner's checklist for choosing a good electrician: verify the LEW licence, EMA class, insurance, quotes and SP notifications before you hire.

How to Choose a Good Electrician (LEW Checklist)

To choose a good electrician in Singapore, confirm they are a Licensed Electrical Worker (LEW) registered with the Energy Market Authority (EMA), match their licence class to your job size, and insist on a written quote with a clear scope. Ask whether the work needs an EMA installation licence or an SP Group notification, and check that they carry insurance. A good electrician explains what is legally required, not just what is cheap.

In Singapore, most electrical work beyond simple plug-and-play tasks must be carried out or supervised by a Licensed Electrical Worker. Using an unlicensed handyman can void your home insurance, breach HDB or condo rules, and create real safety risks. This checklist walks you through what to verify before you commit.

What is a Licensed Electrical Worker (LEW)?

A Licensed Electrical Worker is an electrician, electrical technician or electrical engineer licensed by the Energy Market Authority to carry out or supervise electrical installation work. The LEW system exists so that the person touching your wiring is trained, tested and accountable under Singapore law.

LEW licences come in classes tied to the voltage and load of the installation. For a typical home the relevant category is a licensed electrician handling low-voltage work, but larger jobs or higher loads may require a licensed technician or engineer. Always ask which class the person holds and whether it covers your specific job.

How do I check if an electrician is licensed in Singapore?

Ask for the electrician's full name and LEW licence number, then verify it against the EMA register rather than trusting a photo of a card. A genuine LEW will give you this without hesitation. If someone dodges the question or says a licence is not needed for obvious wiring work, treat that as a warning sign.

Licences also carry an expiry date and a class, so confirm both. An expired licence or a class that does not match the work is not valid cover for your job.

  • Request the LEW's name and licence number in writing
  • Confirm the licence is current and not expired
  • Match the licence class to the size and load of your job
  • Verify the number against the official EMA records

When does electrical work need an EMA licence or SP notification?

Small tasks such as swapping a light fitting or a socket face are generally low risk, but anything touching the distribution board, new circuits, rewiring, or increasing your electrical load usually needs a LEW and may require an EMA installation licence or a formal turn-on request to SP Group. New homes and major renovations almost always involve an application to energise the supply.

A good electrician will tell you upfront which approvals your job triggers and handle the paperwork. If nobody mentions notifications or approvals for a big job, that is a red flag worth pausing on.

What should a proper electrical quote include?

A trustworthy quote is itemised, not a single lump sum with no detail. You should be able to see what work is covered, what materials are used, and what is excluded so you can compare like for like between contractors.

Be cautious of quotes that are far below everyone else. In electrical work, a suspiciously cheap price often means cutting corners on cable sizing, protection devices or the licensed supervision that keeps your home safe.

  • Clear scope of work and the circuits or areas covered
  • Brand and rating of key materials such as cables, breakers and sockets
  • Whether an LEW licence, EMA approval or SP notification is included
  • Labour, warranty period and what is specifically excluded
  • GST treatment and payment schedule

What red flags should make you walk away?

Some warning signs are obvious once you know them. If an electrician refuses to give a licence number, pushes you to skip approvals for major work, asks for full payment in cash upfront, or cannot explain why a certain protection device is needed, slow down and get a second opinion.

Reliability matters too. Poor communication, no fixed business address, and no willingness to put anything in writing usually predict how the job itself will go.

  • Will not share a valid, current LEW licence number
  • Suggests skipping EMA approval or SP notification on major work
  • Demands large cash payments before any work starts
  • No written quote, warranty or contactable business details
  • Cannot clearly explain the safety reason behind the work

Does the electrician carry insurance and offer a warranty?

Ask whether the electrician or their company holds public liability and work injury coverage. If a worker is hurt on your property or a fault causes damage, insurance is what stops the cost landing on you. A settled contractor will answer this calmly and clearly.

Warranty is the other half of accountability. Confirm how long the workmanship is covered and how you would reach them if a socket, circuit or fitting fails a few months later.

Getting the work done safely

Once you have shortlisted a licensed electrician you trust, agree on the scope in writing, confirm any approvals the job needs, and keep a copy of the quote and licence details for your records. This protects both your home and your insurance position.

If you would rather deal with one accountable team, our electrical services cover the licensed wiring, distribution board work and safety checks that Singapore homes need, coordinated alongside renovation and plumbing when a project touches all three. That way the LEW checklist above is handled for you rather than something you chase yourself.

Frequently asked questions

Can I hire any handyman to do electrical work in my HDB or condo? No. Most electrical installation work in Singapore must be done or supervised by a Licensed Electrical Worker, and using an unlicensed person can breach estate rules, void insurance and create safety hazards. Simple plug-in tasks are fine, but wiring, boards and new circuits are not.

How much does an electrician cost in Singapore? It depends heavily on the job, from a small call-out for a single fitting to a full rewiring or distribution board upgrade running into the thousands. Ask for an itemised quote so you can compare scope, not just the headline price.

Do I really need an SP Group turn-on or EMA approval for my job? For minor swaps, usually not, but for new supply, load increases, rewiring or major renovation you generally do. A good electrician will tell you which approvals apply and handle them as part of the work.

What is the difference between an electrician and an LEW? Electrician is the trade, while LEW is the official Energy Market Authority licence that authorises someone to carry out or supervise electrical installation work. You want an electrician who actually holds a current LEW licence in the right class for your job.
