What is a Licensed Electrical Worker?
A Licensed Electrical Worker (LEW) is an individual licensed by Singapore’s Energy Market Authority for electrical work within the applicable licence scope. EMA’s worker-licence overview says electrical wiring work must be carried out or supervised by a licensed worker and tested and certified safe before supply is turned on.
The worker’s licence is different from an electrical installation licence and an electricity generation licence. Establish the requirements for the actual installation rather than treating all three as the same approval.
Classes and authorised scope
EMA’s consumer guide publishes the following limits:
| Class | Approved load | Voltage |
|---|---|---|
| Licensed Electrician | Not exceeding 45 kVA | 1,000 V and below |
| Licensed Electrical Technician | Not exceeding 150 kVA for design; 500 kVA for operation | 1,000 V and below |
| Licensed Electrical Engineer | No load limit | Subject to licence conditions |
Approved load is not simply the PV module nameplate rating in kWp. The distinction between design and operation also matters. Ask the proposed LEW to confirm that the work and installation fall within their actual authorisation; do not choose a class by converting a solar module count directly into a worker category.
EMA directs consumers to verify the worker’s valid licence and provides ELISE as a route to search for licensed individuals. Check the holder and licence details before work starts. A company logo or a sales title does not establish the individual’s scope.
Solar installation licences: check the separate thresholds
EMA’s solar licensing FAQ says residential installations below 1 MWac do not require the installation/generation licences described there. It identifies an electrical installation licence for non-residential installations with load demand exceeding 45 kVA and requires an appropriate LEW for the installation.
The same FAQ describes electricity generation licensing above 1 MWac, measured by aggregate inverter capacity at the grid connection point, while its introductory wording also refers to installations at 1 MWac and above. For an installation exactly at that boundary, obtain EMA’s determination instead of silently resolving the wording discrepancy. Do not substitute DC module capacity for the specified AC measure.
An exemption from an installation licence does not remove the separate requirement for appropriately licensed electrical work or establish permission to connect or export.
Engage the worker around the required deliverables
Before appointment, retain the installation’s use, approved load, voltage, PV equipment and intended connection arrangement. Agree the work scope and who is responsible for the drawings, installation review, testing, applications and records.
Ask which agency and network submissions apply. Keep the worker’s technical certification, installation licence decision and connection documentation separately identifiable. A software report is not the LEW’s certification or an authority’s approval.
The exact documents and inspections depend on the project. This guide does not prescribe protection settings, cable sizes, fixed application times or a universal professional fee.
Applying for a worker licence
Use EMA’s linked licence page for the intended class and its current eligibility and assessment requirements. Follow the official application route. The qualification, experience and assessment conditions for one class should not be copied into another class’s application.
This article does not claim that completing a solar course automatically grants a worker licence, nor does it provide an invented approval timeline.
Keep the project record consistent
For an illustrative review, compare the installation load and voltage recorded in the appointment scope with the submitted drawings. Resolve discrepancies with the responsible worker. This is a document check, not a retained project case or a claim that software validates licensing eligibility.
Use the Singapore compliance hub for the existing country resources and the solar design workflow for document handoffs. When evaluating SurgePV’s engineering workflow, inspect required outputs with the LEW; software does not grant a licence or replace their professional responsibility.
