★★★★★
I have been with Diamond Energy since 2021 after a recommendation and have been very happy with the service. The members who I have spoken to over the phone are always professional, personable and clear in their communication. In comparison to my last provider, my bills have been reasonable even with the increasing costs of living.
Amanda
★★★★★
Diamond Energy are a wonderful company to be a customer of. Customer Service has always been efficient, warm and genuine. I love what this company stands for, and highly recommend them.
Adam
★★★★★
In these dynamic times, we live, often lacking authenticity, and consequently trust it so good to have a company like Diamond Energy, which is transparent in its operations, genuinely supportive and helpful.
Kristi
★★★★★
I've been with Diamond Energy for 10 years. I cannot fault their customer service. Always quick to resolve any issue I have had. Extremely helpful and understanding as circumstances has changed. Can not recommend enough.
Ken
★★★★★
I’ve been a Diamond Energy customer for 7 years and have always found them to be an excellent company to deal with. Asked a question recently about moving house and Lindsay came back very promptly with a clear, detailed and lucid reply. No smoke and mirrors just easily understandable facts.
Nari
★★★★★
I've been with Diamond about 8 years in 3 rentals and now my own home with solar. Highly recommended them, they are fantastic!
Ann
★★★★★
We have been with Diamond Energy for a while now, and have recently moved house and took them with us. Their customer service team are fantastic, every time I have phoned they have been professional and very pleasant to deal with and always give me an answer. The pricing is pretty good too.
Maha
★★★★★
After an initial shock from my former electricity provider about the cost of leaving them, I couldn't be happier with Diamond Energy. Fair dealings with me, as they recognise my solar panels generate more electricity than I use each billing period. Definitely helps with 'Cost of Living' issues many Aussies are currently experiencing! I highly recommend them.
Ali
★★★★★
Great to have a green energy company which I know is moving towards a better future. 100% renewable and no bad investors! The slight extra cost compared to other companies I see as a donation to sustainability 🙂
Kenneth
★★★★★
We have been extremely happy with Diamond Energy and would recommend them to all. We have been with them for a fair while now moving to a new home 12 months ago and bringing Diamond with us. Have recommended to family members and friends. Great people to deal with.
Malcolm
★★★★★
I’ve had dealings with diamond energy recently changing address, and ever since the beginning of working with them a few years ago, I’ve been aware of excellent customer service, very responsive clear answers and genuine efforts to understand my needs. Even when things have not gone smoothly, they have been Quick to address the problems and honest about what’s happening. Can’t recommend them enough, and the fact that this is renewable energy at work is a huge factor for me.
Andrew
★★★★★
I was very pleasantly surprised how much I got back for solar on my bills
Deborah
★★★★★
It is refreshing to have a power company such as Diamond Energy that supports its customers. We were provided with genuine assistance and support when my relative who for various reasons, had overdue bills. I thank Dahlia for her compassion, professionalism, and thorough knowledge of supporting resources applicable to his situation and for her assistance and guidance throughout this process!
Anna
★★★★★
So happy I found this wonderful company many years ago, when searching for the "greenest" electricity because at the time, I purchased a house where I had solar panels installed. And even though I am now in a complex where (so far) we can't have solar panels, I have continued to have the very best, most reliable and affordable service from Diamond Energy. Highly recommended, especially if you are environmentally aware!
JJ
★★★★★
I have been with Diamond Energy for years and have no intention of going anywhere as they are the best, hands down. Diamond is 100 % Australian and 100 % renewables. They have brilliant ethics and I just love how easy and green they make everything. The Aussie customer service team are easy to contact, always super helpful and friendly. Diamond Energy is the best-kept little secret in the energy market. Wow and I just saw they are listed first by CHOICE in 2022 and 2023 as the Best Electricity Provider in Australia. Why am I not surprised? Love your work Diamond and I look forward to many years of being a super happy and satisfied customer. Thank you all so much.
Andrea
★★★★★
Diamond's billing is easy to understand and provides useful information on my usage and feed-in. I'd like Diamond to consider tiered billing on the all day rate to encourage energy conservation.
CJ
★★★★★
Joined Diamond in 2022 and have been pleased with customer service, price, discounts and most of all that my house is supplied with green energy!
