In Singapore, the question of who is allowed to sign off electrical work is not a formality — it is set by the Electricity Act and enforced through the class of Licensed Electrical Worker (LEW) endorsing the job.
The class required depends on the operating voltage and the approved load of the installation, not on how complex the job looks. A straightforward-looking rewiring on a high-load commercial installation can require a higher class of LEW than a more visually involved job on a small residential load.
Why this matters before the quote
Before we price any electrical work, we confirm which class of LEW the installation actually requires and make sure the person signing off holds it. Work carried out or endorsed by someone without the right class of licence is not just a compliance problem on paper — it can invalidate insurance and expose the building owner directly.
If you are unsure what class your installation needs, that is a five-minute question to ask us before any work starts — not something to discover after it is done.
