Everyone is so great and easy to talk to. I've never had issues so I've never had to call and winge. But when I called to disconnect (due to no gas) they answered quickly and the lady I spoke to, Jess, was lovely and helpful. Didn't make me feel bad at all.
Will return when I move

Have found them excellent and cost effective. Very approachable on the phone and spend time to explain. Clear and simple documentation and processing. Good communicators.

There is no point calling their customer service as they don't seem to do anything. Requested to change over to them asap to get the most out of my new solar panels with extra cost involved. Complete mess up, finally connected after 3 months. I feel that I have been very clear with what I wanted. But they have no provide me with what I am expecting.

Company failed to call and let me know my power had failed to shut off. Then received a 200 dollar bill 3 months later after bein told my account was closed. I was required to pay plus extra disconnection fees. No courtesy or accountability. Would not recommend.

Having solar panels and getting the credit is a good thing. After being with origin for years and seeing the fake discounts and price hikes I decided to jump ship and go with diamond. They are good, genuine and also mainly humans. In all this time I have had one problem which got sorted eventually. For all those people who have had issues and complaints please bare in mind these are humans and they do make mistakes, which can be resolved if you treat them like humans and not your slaves who bend over to your demand. Threating or mistreating them will only make things worse as the contract will be enforced even harder.

We have been a customer with DE for 5 years, they were very helpful after we had a solar system installed and getting us signed up.
During the 5 years we have had problems with the supplier (SPAusnet), Diamond Energy sorted these out (incorrect meter readings, estimated readings). These problems were not caused by DE, yet they still resolved them with the supplier. There are not too many companies in any field were you can ring and actually talk to a human, DE is one, their customer service is excellent and i have recommended them to many friends and family.

We signed up for 100% renewable with direct debit. Assumed we were paying quarterly as agreed. 5 months after cancellation because we moved, we get a final notice for entire amount... they hadn't done a single reading in 9 months and we had never received an invoice. No responses to emails and no explanation for constant errors on their part. Avoid this company!

I have solar. Over two and a half years the feed-in rate has dropped from 22c/kWh to 8c/kWh and the daily supply charge has gone up from 50.219 cents a day to 131.44 cents a day, that is an increase of over 150%. Now you must produce more than 16 kWh daily just to cover diamond energy's supply charge. Previously 3 kWh would cover the daily supply charge. How can they justify this?

I applied to Diamond for a switch from AGL. They were honest, friendly and efficient. I am definitely not looking back!

Fantastic customer service, the best power rates and highest solar feed in tarriff. Great green power options too..
Forget powershop... Go diamond !

A green electricity retailer that takes customer service to the next level. No other retailer comes anywhere even close to providing the service that these guys bring to the industry.

I always recommend them to my family and friends.
A+

I love that I can buy 100% renewable energy from a company that ONLY sells 100% renewable energy. Not one of the big fossil fuel fuel companies that begrudgingly sell GreenPower just to keep you on their books while lobbying behind the scenes against the Renewable Energy Target and other carbon reducing policies. Diamond Energy are also very friendly on the phone, which I like.

Was looking for an electricity retailer with good green credentials and locally based (no international call centres please - I haven't got time to waste) and came across Diamond Energy - answered the phone straight away, fantastic service and nice people. I would recommend them to anyone.

I heard about Diamond Energy and decided to join up because they support renewable energy. I called up and to my surprise they answered the phone with only a couple of rings. I was expecting to wait in a queue for ages. They gave me good advice and I then signed up in a couple of minutes on their website. Easy - no hassles. I would recommend them to anyone. Their rates are good too.
