Diamond Energy refused me service, ruined my credit score and now I’m unable to take out a home loan. I attempted to call multiple times, waited 5 minutes each time before their automated line hung up on me. They did not indicate why they refused me service. After speaker to a resolution person, they told me my credit score wouldn’t be… Read more

impacted, they then told me to take it up with Equifax if it did. They state that their standard checks include credit checks, my credit score is excellent, never missed any payments ever. Due to the declining of service , my credit score has now been significantly impacted. I am now unable to secure a home loan, because of the impacts to my credit score from Diamond Energy.

This is purely discrimination and likely breaches their legal obligations of providing services. If you need energy for a place you are moving into, don’t choose Diamond. Because I applied online and selected my start date and entered all of my details, I expected to be provided energy for my move in date that I had selected. Instead, I found out they refused me service, and was living in my property without energy for 3 days due to not being able to connect to another service until then.

Honestly disgraceful.

Diamond deserves more than 5 stars – A year ago, after a recommendation from the Whirlpool website, we changed to Diamond Energy. Immediately our bill was a lot less with our Solar credit a lot more. We like the way the bill is laid out and our credit is paid direct into our bank account every quarter. It's good to deal with an Australian based company who are pleasant to talk to and… Read more

are efficient and understanding.

After issues with Energex QLD, regarding the removal of our Solar Bonus Feed In Tariff, Diamond Energy went in to bat for us. They were on the ball and chased up Energex when we were not getting any response. After 3 months of lots of stress and anguish, Energex finally restored our feed in tariff, what a huge relief. Without Diamond's help we would still have not resolved it all.

During this 3 month period, Diamond Energy also upped our Solar tariff, while this issue was being sorted out.

Excellent, efficient and friendly customer service. We know a lot of time and effort was put in by our customer Service representative, we thank her for this and are extremely grateful for all her help.

Highly recommend Diamond Energy.

Great customer service – I like to ask LOTS of questions and be 100% sure before committing I interviewed 4 Solar installers before settling on a 12 kwh system from Green Energy Australia (ps ask for Randall) They recommended Diamond as cost competitive and a great local supplier. I did my research and was ready to hit up the electricity providers and after making… Read more

several calls and have settled on Diamond primarily because they have great customer service. Also they are the wholesalers for the new SSC solar farm.

Phone service was great. Instantly connect with a human, clear speaking and friendly, had answers for ALL my questions, and provided realistic feedback about options for battery. When I asked about price comparisons, They took a copy of 2 recent electricity bills and generated two clear reports showing savings compared to AGL. Then they added sweeteners for installation and ongoing higher feed in tariff. And have offered to absorb the cost of accelerated cut over meter read..

Email notifications from Diamond have been appropriate keeping me notified of progress. It seems I anticipate the welcome pack will arrive any minute.

I was considering changing electricity provider because I was not getting the full use out of my current plan. But Jules (B2B officer) informed me of options that I was not aware of, which led me to keep on using Diamond Energy. Compared to competition, I won't actually save a considerable amount. But, now I may even save money being with Diamond Energy. Show details ·  1

Horrible - they took over our electricity account without permission as they mixed us up with our neighbours. After receiving dodgey letters addressed "To the Home Owner" with threats to pay them, they clearly didn't have our personal details. They then turned off our electricity and admitted fault, but gave me a default on my credit report. 7… Read more

years later and a mark on my credit rating stopping me investing for 7 years! Finally, the debt came off my credit report and they have come back to threaten me again just this week with a debt collection agency. Still trying to get rid of Diamond Energy, a company I never signed up to or agreed to be with. No contracts exist between the two parties, yet I am punished for years. And the Statute of limitations for debt (which i should never have been given), ignored. Illegal SHAMS.

Overcharging and cheating seems to be their business model – We’ve been with Diamond for many years and recently, our bills are twice what they used to be. We’ve been away on and off the past few months, not using air-conditioning or heating, and we barely have any appliances. Despite this, we were just hit with the highest bill we have ever received, literally the highest usage per day EVER… This seems to… Read more

be a common trend with Diamond recently, their customer support people have also had a chip on their shoulders when bills queried in the past. We signed up because they were ranked the highest in terms of sustainability however, their poor/complicated energy usage charges and seeming overcharging is making us consider going elsewhere.

Four times more expensive than my previous supplier – We switched to Diamond because we wanted to go 100% green. We did our due diligence and even rang the company to speak person to person and make sure we checked the claims on their website. Just received a quarterly electricity bill for nearly $1000 for a period where we were away from home most of the time and I feel sick to my stomach. The bill… Read more

structure and breakdown is the most confusing and strange one we’ve ever seen. There are several different sections, all with different tariffs and charges. They way they break things down I think is designed to be hard to understand and is very different to what you would get from other providers. I’ve compared this bill to a very recent one from our previous supplier and it’s four times more expensive. We are getting away from Diamond as fast as we can as this has been a horrible experience.

I signed up to Diamond Energy some months ago. Signing up was more complex than expected and billing can kindly be described as erratic but these are minor issues given that the rates are extremely competitive and customer service has been as good… Read more

as other reviews indicate. The low score is due to an email I recently received advising that payment on an invoice is overdue. The payment was made the day the invoice was received, a fact that Diamond Energy's own website clearly shows. Whether this alarming and deeply offensive accusation of non-payment is due to incompetence, something about which I already harboured suspicions in regards to this company, or reflects some darker intent I cannot say. I have reported the matter to Diamond Energy and await a reply. I recommend that you approach this company with a degree of caution and make a habit of keeping an eye on your account online.

 Follow-up  · The issues with billing and signup were both minor. The billing was a matter of the timing being unpredictable - never on the expected day and occasionally not for the expected period - and I found the bills themselves extremely difficult to interpret. Both issues appear to have been sorted out and hopefully were teething troubles. They are… Read more

I ran into an issue during moving where my new property's electricity was remotely disconnected and tragically Diamond were unable to reconnect me remotely. Jules was wonderful and patient in assisting me throughout the whole process and while there was a brief period without power, we were able to get everything running again with Diamond. Show details ·  1

I have been with D/Energy for yonks and have never experienced a bad session. Today the customer service person was very helpful, my usual experience, and emailed me immediately with what I requested. My responses, if I have to compare, have been a bit woeful because of the huge changes every minute of the day, sending me potty!! But I managed… Read more ·  1

today pretty well so a thumbs up for me! Please bear in mind IT is becoming soooo complex especially as one ages with changes by the minute in so many areas, and this is where you have, for me, really shined. Keep up your valiant awareness and patience across the board please. As for my electric power, I intend keeping up with maintaining low rates of power as much as I possibly can. Big ticks all around with huge thanks. Sue

Thoroughly recommended. Very rare to find a business this efficiency run and the customer service is 10/10 in an age when the big companies can barely rate a 1/10. The price is lower than many of the alternatives too. I never write reviews, but never say never i suppose. Show details ·  1

Very happy with Diamond. Switched a few years ago, when Powershop went bad. Initially Diamond advised they had no capacity for new customers, but then contacted me by email when capacity increased. My power bill is noticeably less since the switch - getting the quarterly bill is still a nice surprise each time, yeah that doesn’t get old - and the process was quick and smooth. Electricity for a unit. Thank you Diamond. Show details ·  1

I just spoke with Mishka about our energy bill and solar panels etc and they were so helpful, friendly and professional. They were able to patiently and thoughtfully answer all of my questions despite my glaring lack of knowledge. I would highly recommend this company based solely on this interaction. This person deserves a raise! Show details

Supportive and compassionate power company – It is refreshing to have a power company such as Diamond energy who support their 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! Show details ·  1

Do not bother – Getting on was easy, closing the account, not so easy. Written advise is not enough, a phone is not enough and even when all is aligned, still not closed. Customer service lacks knowledge and communication skills, either to the customer or to other colleagues. They just won't let you leave. Ombudsman is the next step. Show details

Good customer service team but fees will apply for switching so double check your quote with them before signup – We have experiences with many other retailers before but were never charged for a transfer, so find it unusual to be charged a $22 establishment fee for our transfer to Diamond. We also found the prorated billings and two tier rates structure confusing but thanks to the customer team, we had a fair resolution to our issues. Show details

Diamond Quality Energy Company, with Sparkling Staff – I had an extremely productive discussion with the Diamond Energy call centre - the staff member was incredibly knowledgeable, and was able to get deep into the technical aspects (and it was a low-level technical issue). I am impressed that Diamond Energy staff are so technically literate, and very good communicators. Thank you Diamond Energy, and thank you to Annie N for her excellent work! Show details

Very happy customer – Have been using Diamond Energy for about 5 years - we chose them for originally for their focus on renewables but have been pleasantly surprised by cost of electricity, as I was expecting to pay more. Their customer service is fantastic. Whenever I have had reason to call them, the call is answered within a few rings, the person on the other end is friendly, helpful and knowledgeable. We are very happy customers. Show details

If I could score below 0 I would! – If I could score below 0 I would. Worst company ever! I was recommended to use this company by a friend. Worse decision I EVER made. Feed in tariff is quite low.

Someone answered the phone - YAY – Have been with Diamond Energy for 2 or 3 years now. Excellent service. Real people answer the phone and help. My bill has reduced with time so I find it OK. Power supply reliable (in Brisbane). Can't speak highly enough about them. My mother is with another company and pays nearly the same as our household with 4 people. Show details
