Yes, Diamond Energy has some of the most competitive electricity rates in South Australia for residential and small business customers. We continually appear as one of the lowest cost electricity retailers in government price comparison websites (eg. Energy Made Easy).


Can Diamond Energy supply power to my property?

We have been supplying electricity to residential and small business customers in South Australia for over four years – providing competitive rates and great service.

We also supply electricity to residential and small business customers in VIC, NSW and Qld 

Is there any disruption to my power supply during the switching process?

No, your power will not be cut off. Switching just involves the transfer of information from your current electricity retailer to us.

What if I'm on a contract but want to switch?

Switching to Diamond Energy is easy. We handle it for you, including contacting your existing retailer. If you are on a contract with your existing electricity retailer you can find out from them whether there are any exit fees associated with changing, but ultimately they can’t stop you switching.

How long does it take for Diamond Energy to become my retailer once I have completed the on line application?

This will depend on where your supply address is located and also your local electricity distributor.

If you are in VIC, SA or QLD (Energex only), your transfer to Diamond Energy will most likely complete as your meter is upgraded.

If you are in NSW, in most cases you will transfer the next time your poles and wires company reads your meter.
