We continually appear as one of the lowest cost electricity retailers in government price comparison websites (eg. Energy Made Easy, My Power Planner).  You can view our rates in your area here.


Can Diamond Energy supply power to my property?

We have been supplying electricity to residential and small business customers in VIC, NSW, SA and QLD (Energex region) for over three years – providing competitive rates and great service.

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.

What happens if I don't want to take up the Diamond Energy WattBank50 offer?

The Diamond Energy WattBank50 offer is included with your approved solar package at no additional cost.

We can’t force you, but if you chose not to take up the Diamond Energy WattBank50 offer, you will miss out on:

  • the high feed-in rate for 3 years (only available through Diamond Energy)
  • competitive rates for solar customers; and
  • expert, solar friendly service helping customers every day with hassle free transition to solar to enjoy many years of electricity generation from their rooftops.

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.
