Licensed Electrician (LEW) Services in Singapore

Straightforward prices for all your electrical needs.

What Is a Licensed Electrical Worker (LEW)?

A Licensed Electrical Worker (LEW) is authorised by the Energy Market Authority (EMA) to carry out, supervise, or certify electrical works. From installing power circuits to endorsing submissions, LEWs play a crucial role in ensuring safety, compliance, and operational integrity across residential, commercial, and industrial sites.

Role of a LEW in Electrical Works

In Singapore, a licensed electrician must be engaged when working with higher-voltage systems, performing complex upgrades, or submitting documents for electrical turn-on. LEWs help assess electrical load, ensure code compliance, and sign off on key installations.

Why Hiring a LEW Matters

A licensed LEW is not just a formality. They are legally required for specific categories of work and bring technical expertise and regulatory knowledge to every project. You can view the official list of licensed electricians in Singapore through EMA’s portal.

Who Needs LEW Services?

LEW involvement is required not only for large-scale developments but also for specific upgrades or installations. If you’re unsure whether you need a LEW, here’s a quick guide:

Homeowners Renovating or Rewiring

If you’re upgrading your distribution board or increasing your electrical load, a LEW is required to supervise and endorse the installation.

Businesses Installing New Systems or Upgrading

New commercial setups, increased electrical usage, or switching to three-phase power all require a LEW service to ensure legal compliance.

Developers and Contractors Needing Certified Oversight

Construction or A&A works involving temporary or permanent power supply must be managed and endorsed by a LEW before power turn-on.

Facilities Requiring Ongoing Electrical Maintenance

Industrial facilities, data centres, and larger buildings with complex systems benefit from routine LEW inspections to prevent faults and downtime.

SP Testing Before Power Turn-On

Safety First: Before any new or majorly modified electrical installation can be powered on, it must undergo a mandatory inspection known as SP Testing. This ensures all wiring and components meet safety regulations, reducing the risk of electrical hazards.

Permit to Power On: Only after passing this inspection will SP Group issue the green light to activate the electricity supply. A LEW must be engaged to carry out the test and endorse the setup in accordance with local regulations.

Frequently Asked Questions About Licensed Electrical Workers

What is the difference between an electrician and a Licensed Electrical Worker (LEW)?

While general electricians handle most day-to-day electrical tasks, a LEW is licensed by the EMA to take on higher-risk or regulated jobs, such as supervising installations, certifying documents, and submitting applications for electrical turn-on.

Do I need to engage a LEW for residential electrical works?

Not all residential work requires a LEW. However, if you’re upgrading your main switchboard, increasing load capacity, or applying for a Temporary Supply (TS), then yes, you’ll need an EMA-licensed LEW.

Can 81 Electrical help with SP Group electrical turn-on applications?

Yes. Our team handles end-to-end support, including testing, endorsements, and application submission to SP Group for a smooth and compliant power turn-on process.

How do I know if the LEW I’m hiring is certified?

All LEWs must be registered under the Energy Market Authority. At 81 Electrical, our team includes certified professionals who are listed and recognised by EMA.
