Affordable green energy, excellent customer service
Renewable energy that doesn't cost any extra. As someone who lives in an apartment and cannot get solar, this is the perfect solution for me to lessen my impact on the earth. On top of this, the customer service that Diamond Energy delivers is outstanding - always quick to respond and very helpful. I've been a customer for about 7 years now and will continue to be. I highly recommend them.

Highly recommended
Highly recommended! I believe they are an ethical and competitive choice for energy provider. I 'inherited' Diamond Energy from the previous home owner when I moved to the Northern Rivers 2 years ago. It was such a great surprise to be helped by friendly and knowledgeable staff over the phone and the service has been hassle-free ever since.
