Fact Checked

Diamond Energy is a small electricity retailer that’s passionate about renewable energy. The retailer launched in Victoria in 2004 with ‘a vision to generate change in the Australian energy marketplace’.

Today, Diamond Energy retails power to homes and small businesses across New South Wales, South East Queensland, South Australia and Victoria. Diamond Energy claims that switching electricity retailers and joining its ranks is a simple and positive way of making a difference.

Some consumers may already be sold on this environmentally-focused retailer, but for the rest, let’s take a closer look at what Diamond Energy offers and whether it presents good value.

Being an environmentally-focused energy retailer is one thing, but what can you actually expect to pay with Diamond Energy? To help you decide if this is the right retailer for you, we’ve estimated annual costs across the states below.

An expert’s guide to Diamond Energy

Not all energy retailers sell electricity or gas in every state across the country. That’s why we’ve summarised what you can expect to find from Diamond Energy below.

Diamond Energy plans

Diamond Energy only has one market electricity plan, simply called ‘Everyday Renewable Saver’, available in New South Wales, Queensland, South Australia and Victoria.

• Everyday Renewable Saver: Customers receive a modest discount if the bill is paid on time. Further savings are on offer to Victorians who sign up pay their bills via direct debit, and refer a friend to Diamond Energy.

Diamond Energy solar

Diamond Energy’s range of solar products and services is what truly distinguishes this retailer from its competitors. Customers signed up to Diamond Energy’s market offer receive a feed-in tariff of up to 5.2c/kWh.

Diamond Energy does not directly retail or install solar systems, so you will need to organise this through a third party. Diamond recommends using a Clean Energy Council accredited solar installer and has a list of preferred suppliers on its website, which it refers to as its ‘Pure Power Installers’. To see which of these installers are available in your area however, you’ll need to contact Diamond Energy.

Some solar customers may also be eligible to join Diamond Energy’s Virtual Power Plant (VPP) and earn credits for sharing their exports. Please note, customers will require a solar battery to join this program.

Diamond Energy billing

No one likes paying bills, so it’s at least nice if retailers make the process as painless as possible. Diamond Energy has eight ways for customers to pay.

• Credit Card – Pay using VISA or MasterCard.
• Direct Debit – The money is automatically withdrawn. Customers receive a 3% discount for paying using this method.
• Electronic Funds Transfer – Use the bank details on your bill to send the funds directly to Diamond Energy’s bank.
• BPAY – Use the Biller Code and Reference Number on your bill to pay with BPAY.
• Australia Post – Pay with cash, EFTPOS or cheque at Australia Post.
• Mail – Mail a cheque or money order with your payment slip to Diamond Energy.
• Bill Smoothing – Set up weekly, fortnightly or monthly direct debit payments to avoid being slugged with large quarterly bills.
• Centrepay – Organise some Centrelink payments to be direct toward your bills.

Is Diamond Energy right for me?

Diamond Energy is not your typical retailer and won’t be for everyone. Diamond’s feed-in tariff, along with its VPPs, could make it a great value retailer for customers with solar.

Customers without a solar system can still sign up to Diamond Energy, however our calculations suggest that such households might be charged more for electricity than they would be elsewhere. When comparing electricity retailers, be sure to observe the rates, discounts, feed-in tariffs and other solar incentives.
