Who is iSwitch

We are an electricity retailer licensed by the Energy Market Authority (“EMA”) to serve the market. Our goal is to empower consumer choice—to give you more options to better manage your energy costs.

With you in mind, we have developed a suite of Value Plans. Each iSwitch plan offers a different level of flexibility but all are designed to help you achieve cost savings while enjoying the same, reliable electricity supply from Singapore’s national power grid (known as SP Power Grid).

This is made possible by the deep industry experience of our team and the strong support of the RCMA Group, of which we are a member.

We invite you to meet the iSwitch team, who brings with them extensive electricity retail experience across the Asia Pacific region. You are also welcome to trace our history, which dates back to 1964, and learn more about our parent company the RCMA Group-an established player in the global commodity and energy sectors with an annual turnover in excess of US$1 billion.
