Excellent service!

published

I have been with Diamond Energy for some years now and have found them to be consistently pleasant, helpful, efficient and cheap. Apart from short breaks in supply during the occasional electricity storm I have had no power interruptions.

Many hidden charges

published

Admittedly I did not do my research prior but just got a bill for $424 for 4 months - one bedroom flat, no air con, lived there for 2 months, for sale for 2 months with Real Estate Agent turning power on at meter for 30 minute inspections only. I did not realise this company charges 109 cents per day for electricity whether you are using it or not, nor was it clear about the connection charges. Cant wait for the next bill with the disconnection charges.

Amazing customer service

published

Diamond Energy you are amazing! I found myself in difficult times and unable to pay my bill in full . I called customer service to discuss and i was so nervous and had some anxiety initially... i even worked myself up to make the call. This was due to previous bad experiences in the past. Well! The lady i spoke to was so warm and friendly and completely understanding. I was soon relaxed and felt like i was talking to someone i knew. She efficiently and calmly helped me to a solution and I didnt feel any judgements upon me at all. Congratulations Diamond on having staff who truly are “ Diamonds in the rough”

April 11th 2019 Update: Re Over Payment Refund Diamond Energy

Great expectations

published

Diamond Energy has been our supplier since we switched to Solar about 7 years ago. Every now and then I do some research to see if i can pay even less. I usually find that Diamond Energy is the cheapest based on daily avg kwh and the price even if it is only a few cents, it still shows i'm paying the least so there is no benefit to switching away.

A great, green company

published

Finally, an electricity company that is transparent and offers great service. We have a premium feed-in tariff. When we're in credit, Diamond pays our bank account on the day the invoice is due. Never had that before! They rank second on the Greenpeace Green Electricity guide, with all renewables (no fossil fuels). That's the most important factor for us.

Top customer service

published

Life is not always about the cheapest price as cheap service usually hangs together with it. Diamond Energy goes against this by offering very competitive prices and best of all, excellent customer service. I have called a number of times and the call gets answered straight away by very friendly Aussies who sort out problems on the spot. It makes customer service at the other retailers look like a complete joke.

Consistent, perfect renewables power supply at great rates

published

Hands down the best electricity company I have ever dealt with. And the only one to ever offer me discounts. If you believe renewables are the future, I'd recommend them.

Easy to deal with.

published

House is 100% electric.
Switched over a couple of years back form another supplier after they upped their pricing and did not tell anyone.
Diamond Energy are easy to deal with and their supply charges seem to be a little cheaper than all the others I have checked with.
I check constantly what other suppliers charge, Diamond Energy still rate the best.
Billing is easy and direct debit is convenient.
My only criticism is that you cannot access your account on their web page as you can do with others.
With all the discounts I have obtained with them, my bills are almost manageable.
At this stage I am a happy Diamond Energy customer.


Always honest

published

Always been happy with diamond. Have left them in the past. HUGE mistake. Back now ppl in the office actually answers your calls and Australian based and owned as far as I know. Just better than the rest. And I sent solar for a living so looking at bills constantly.


Bill shock!

published

Recieved a $1350 bill from these guys after recently signing up. I have a two bedroom unit and usual bill is between $300-$400 with previous companies.
Be very careful!

Best electricity company yet!

published

Very helpful customer service, and extremely good rates. I'm very happy with them. Other electricity companies were an absolute nightmare to deal with, but for over a year now with DE, I have no more issues! And they just emailed me to let me know that the rates have gone down, and that I'll be saving between approx $150-200 per year.

A great, hassle-free experience

published

After being given the run-around by AGL Electricity several times, I was looking to change. And Diamond Energy seemed to be head and shoulders above the rest. And so far the experience has been very pleasant and hassle-free. Customer service is excellent, and pricing is certainly fair. I wish they'd do Gas too.

100% renewable sources, reliable, great customer service

published

After years with AGL & Alinta, I became alarmed at their exorbitant price hikes, so I switched to Diamond Energy. My elec bills are much lower, I like that DE sources its energy from renewables not dirty coal, the supply is reliable and their customer service is excellent! Wish they also supplied gas but not as yet.


Service is the clincher.

published

Diamond does the best kWh/hr deal for my personal house hold consumption and PV production. (ToU) Others sometimes get close but what $ value can you put on being able to get quick sensible and informative answers over the phone (every time I have called)?
I have considered churning several times but over approx. 3 years with Diamond, the numbers (for my circumstances) when crunched convince me that great customer service is the clincher. Thanks Jess and Luke.

Should I only go with Diamond Energy if I have solar panels? I am moving out and will be renting so we won't have solar, will it still be a reasonable price?

I think they do a bill compare if you ask them. They did it for us. They're good even with no solar.

I'm looking at Diamond Energy, I'm in an apartment so trying to work out whether I need solar panels or not?

It would be tricky to get solar panels in an apartment but Diamond energy is sourced from renewables, so at least you know you're helping the planet!

Is it more expensive to have solar on private rentals than owning you own home?

I can only speculate, that as a tenant, after getting the owner's agreement to install panels, if indeed you are responsible for the electricity bill as most tenants in Australia are, you would earn as much credit for the electricity your panels generate as an owner would, but without the security of tenure an owner has, you will have the extra costs of uninstalling, taking the system with you and reinstalling on your next rental property...if you can find an owner who agrees to it.

Hi.
We have solar panels, a 5kw system.
Diamond energy give us 11cents per kw put back into the grid.
But I think the main benefit is that with solar it uses the power generated for the home use first then any excess going back into the grid.
My bills have more than halved since installing solar.
Try using your heavy electricity usage between 9am and 2pm if possible, that is the maximum gain period for solar.
I must admit I have not heard of anyone taking the solar installation with them when they move.
The way new technology is going, there will be bigger and better all the time.
Hope that helps you.

If your bill is 800 plus you may benefit. Personally I would go halves with the owner and only if your bill is really high
