Your power bill includes important information about how much power you've used and how much you need to pay.
If you want to know more about the different parts of your power bill, or interested in why the charges are what they are, then contact your electricity retailer, or see this breakdown of an average power bill via the Electricity Authority’s website.
When you purchase electricity there are rights and obligations for you.
You also have a right to fair and honest dealings with your retailer. Energy retailers, like all businesses, must comply with laws around advertising and marketing. There also specific rules that door-to-door and telephone sales people must follow.
