In Australia, compare appliances using the Energy Rating Label, checking both the star rating and estimated annual energy use in kWh. Compare models of a similar size and capacity, because a larger appliance may use more power even if it has more stars. Work out likely running costs by multiplying the kWh figure by your electricity tariff, then consider the purchase price, features and expected lifespan. Check the official Energy Rating website for current 2026 information, as label requirements and minimum standards can change.
