In Australia, compare the Energy Rating Label’s star rating and estimated annual energy use, rather than relying on the purchase price alone. Check the appliance’s size and capacity, because a larger model can use more electricity even if it has a similar star rating. The energy rating database can help you compare available models, while features such as efficient wash cycles, heat-pump technology and smart controls may reduce running costs depending on how you use the appliance. For a realistic estimate, compare the label’s usage figure with your electricity tariff and ask the retailer for current product details.
