• A large number of complaints to the energy regulator.

• Bad reviews online.

• Mistakes on your bill, such as an incorrect meter number.

What is the difference between a tier 1 and tier 2 energy retailer?

• Tier 1 retailers hold more than a 10% market share in the network region. Tier 1 retailers include Origin Energy, AGL and EnergyAustralia.

• Tier 2 retailers are the remaining retailers who hold less than 10% market share in a network region.

They are typically privately-owned retailers like 1st Energy.

What's the best energy company?

This really depends on what state you live in, your household's particular energy usage needs, and what you value. It's best to compare your options from multiple retailers, particularly as the industry continues to evolve and new offers enter the market. Don't forget, being larger in size doesn't automatically mean the 'best' or cheapest deals.

• 2

  If you don't shop around for energy providers, you’re probably leaving your savings on the table by failing to compare better value options.

• 3

  Most energy providers offer discounted rates for new customers, which is a strong incentive to switch.

  There should be no interruption when you switch energy providers. You'll need to pay a new company for your energy, but there won't be a disruption to your power supply.
