What our customers say...


"I have now been with Diamond Energy for over 4 years, and continue to be impressed by their service, and support for any other projects that I am considering, big or small. This 100% customer focus means I will never have to look elsewhere for my power requirements again, a view shared by many of my family and friends who have now also made the change to Diamond Energy as their retailer.”
