Diamond Energy's plans fall around the middle for price. Check the plan cards above to see how its plan in each state compares with the government reference price.
However, some of its prices rely on conditional discounts (e.g. a pay on time discount, which also requires you to get your bills by email). This means that if you're late paying a bill, you'll miss out on the discount for that bill.
That said, Diamond has excellent renewable credentials. It not only gives customers the option to support renewables in Australia for an extra fee with GreenPower, but it also generates more renewable energy than its customers consume.
Diamond Energy does not sell natural gas, so you can't bundle your energy.
