If you’re starting a career in the electrical industry, obtaining a LEW 7 licence is one of the most important steps you can take. In Singapore, electrical work is strictly regulated, and only certified professionals are allowed to carry out installations legally.
This guide explains everything you need to know about LEW 7, including requirements, job scope, salary expectations, and how to get certified.
