Supply Installation Licence – Ensuring Safe and Compliant Temporary Electrical Installations in Singapore

In Singapore, electrical safety is governed by strict regulatory standards designed to protect people, equipment, and ongoing operations. One of the most critical regulatory requirements for temporary electrical systems is the Supply Installation Licence. Whether the installation is used for construction sites, temporary facilities, outdoor events, or generator-powered operations, this licence ensures that electrical systems are safe, properly tested, and legally approved before being energized.

At RES Engineering Services, we support clients across commercial, industrial, and infrastructure sectors by managing the entire Supply Installation Licence process—from technical assessment to final approval—ensuring full compliance, safety assurance, and uninterrupted project progress.

A Supply Installation Licence is a mandatory approval issued by the Energy Market Authority (EMA) under Singapore’s Electricity Act. It certifies that an installation — whether a temporary site generator, high-voltage network, or permanent industrial setup — meets all necessary technical and safety standards.

The licence ensures that the installation is managed by Licensed Electrical Workers (LEWs) and that all testing, protection, and safety mechanisms are in place before operation. This is not just a regulatory requirement; it is a guarantee of safety, reliability, and operational efficiency.
