How refreshing to speak with any of the Diamond Energy team, they're so friendly and helpful and I love that. Friendly isn't a word I would have used when calling my previous company, nor was it user friendly. I went on the government compare website and Diamond came out on top. Good Rates, Good Service, that calls for a five star rating!

Loyalty reward
Spoke with a staff member about my solar and negotiated a better rate as a long time loyal customer. Who says loyalty doesn't have it's benifits in 2020.
Thanks Diamond or is that platinum....

competitive prices
Really competitive prices together with positive, quickly reactive, well meaningful staff .
No notification
Service has been very good over the years, however when our inverter blew up and we were no longer putting energy into the grid, Diamond Electricity did not notify us of that fact. A family friend had the same problem and were notified by their supplier and were able to rectify the problem immediately. We unfortunately went a whole quarter before we realised there was a problem.

Too expensive but ethical
Too expensive and lack of communication between departments and transparency. Diamond have since contacted me which I appreciate, however I am still considering going with another provider but do support the ethical priorities that Diamond have
