Diamond Energy Reviews

  • Here's how customers rate Diamond Energy across the web:
  • Product Review: 3.9 Stars 78
  • Google Reviews: 4.1 Stars 82
  • TrustPilot Reviews: 4.7 stars 94
  • CHOICE review: 76%

We took a look around the web at Diamond Energy reviews to see what customers thought about Diamond Energy.

Overall, Diamond Energy received high marks from customers.

By taking into account the ratings from the sites mentioned above we can estimate that Diamond Energy customers have an 83% satisfaction rate. This is considerably better than other energy providers.

Positive Diamond Energy reviews from customers mention the company's customer-first mentality and receiving large discounts with solar panels.

One customer left the following Diamond Energy review: I'm a long time customer with Diamond Energy. I like to support renewable energy and support companies who work in that direction of creating a sustainable future.
The products at Diamond Energy are very competitive and the customer service is always great, fast and uncomplicated. They also support you in choosing the right product and tariff for your circumstances. I also like their referral program which gives me long term and ongoing discounts on their products. – Andy N.
This review echoes so many others that talk about the ease of doing business with Diamond Energy, and how they see fairly priced green energy with an uncomplicated approach to customer care.

Another happy customer left this Diamond Energy review: I have now been with Diamond Energy for 6 years. I have always been happy with their feed-in credit, even though it has dropped by 2c, but the discounts I receive make up for that. They have always been very helpful and responsive when I have rung with issues. I say "go away" (not so politely) when those pesky various call centres ring. – Lyn T. It's not like most customers to be so supportive of their energy company or to defend them publicly, but this is a common trend seen throughout many of the Diamond Energy reviews we found.

Still, there are some negative aspects to any company. For the most part customers tend to complain about Diamond Energy's Green Power charge called the Diamond Pure Plus charge.

This can be seen in one customer's Diamond Energy review: Be Aware of hidden charge so call Diamond Pure plus 100%. The company charge me more than $60 on every invoice on top of Electricity under the name of Diamond pure plus 100%. Many customers not aware that this fee is not required to pay and it's on top of their electricty usage. Stay with them if you want to pay extra charges and hidden fees. Diamond Pure Plus is the name of the option charge offered by Diamond Energy to add Green Power to your plan. It appears there were several customers paying this fee without being aware it was optional.

In this case, the solution is quite simple. It's important you do your research before deciding to switch energy companies, and that includes Diamond Energy.

Diamond Energy Green Offerings

For customers with an interest in renewables and solar power, Diamond Energy offers attractive green energy options.

Most notably Diamond Energy offers:

  • Green Power & Diamond Energy Pure Plus
  • Diamond Energy Solar GridCredits 100

Green Power & Diamond Energy Pure Plus

The Diamond Energy Pure Plus programme is the name of Diamond Energy's Green Power initiative.

With the Diamond Pure Plus programme, Diamond Energy offers Green Power at an additional charge of:

  • 5.5c/kWh = 100% Green Power
  • 2.75c/kWh = 50% Green Power

By adding Green Power to your energy account, Diamond Energy will commit to purchasing energy from accredited renewable energy generation sources for the equivalent of however much energy you use. Adding Green Power is a great way to ensure your energy is coming from renewable sources, encourage energy companies to purchase energy from renewable generators and also reduce your carbon footprint.

You can add or remove Green Power from your account whenever you like.

Diamond Energy Solar GridCredits 100

Perhaps their most attractive offers are Diamond Energy’s solar feed-in tariffs and GridCredits100 plan.

Diamond Energy offers a standard 7c/kWh payout rate for solar feed-in tariffs. While this number may seem a bit low, it's actually higher than the market offer in most areas of Australia.

However, if you really want to earn money from your solar panels, Diamond Energy offers certain customers access to their Diamond Energy GridCredits100 plan. The GridCredits 100 plan is only available for customers with solar battery storage systems.

With the GridCredits100, Diamond Energy will purchase electricity from your solar battery at a price of $1/kWh when energy is in extra high demand.

In this way, Diamond Energy can help relieve pressure on the energy grid and solar battery owners can make an extra dollar.

Diamond Energy Solar panels

If you don't have solar panels and are interested in purchasing some, Diamond Energy works with third-party retailers to provide solar panels to households in Australia.

For more information on buying solar panels through Diamond Energy, you can contact them by email.

You can find a list of accredited solar installers in our guide to solar energy and the Clean Energy Council.
