Course Overview
The EMA Licensed Electrical Worker (LEW) licence is a legal requirement for anyone supervising or carrying out electrical work on electrical installations in Singapore. Obtaining the licence requires passing a written examination set by the Energy Market Authority covering Singapore's electrical regulations, technical standards, and installation requirements.
This two-day preparation course is designed to give candidates the structured revision, technical grounding, and exam strategy they need to pass first time. All sessions are led by our practising LEW engineers — people who have sat and passed the examination themselves and work with Singapore's electrical regulations every day.
Pass rate matters: The EMA LEW examination has a significant failure rate among unprepared candidates. Structured preparation with practising engineers consistently improves pass rates compared to self-study alone.
