What Canstar Blue brings
Canstar Blue is best known for its consumer star ratings (surveys of customers that rate retailers on satisfaction, value, billing and service) alongside a comparison service. Those star ratings are a genuinely useful signal, because price is not the only thing that matters; how a retailer treats you when something goes wrong counts too. If you want a sense of a retailer’s reputation before you switch, Canstar Blue is a helpful reference.
Alongside the ratings, Canstar Blue also runs commercial comparison, which generally means referral arrangements with participating retailers. So the offering blends survey-based ratings with a commercial comparison layer.
Ratings answer a different question than "what will it cost me?"
A star rating tells you how other customers felt about a retailer on average. That is valuable, but it is not the same as knowing what a specific plan will cost your household. Two people with the same retailer can have very different bills depending on their usage and plan, and a satisfaction rating cannot tell you which plan is cheapest for you.
EnergySorted answers the cost question directly. It costs every plan against your actual usage read from an uploaded bill (peak, off-peak and shoulder, solar feed-in, and gas stepped rates) so you see the real dollar figure for your home, not an average sentiment. The two tools are complementary: reputation from ratings, precise cost from real-usage costing.
Independence, coverage and ongoing tracking
Because Canstar Blue’s comparison layer is commercial, it carries the usual referral-model considerations and may emphasise partnered retailers. EnergySorted takes no retailer commissions (you pay a small yearly subscription of around $39) and compares the whole AER-listed market rather than a panel.
EnergySorted also keeps working after the switch: a Bill Health Score, next-bill forecasts, explanations of why a bill changed, and coverage of electricity, gas and fuel together, backed by a savings guarantee. Star ratings are refreshed periodically as a general guide; EnergySorted is tracking your specific bills continuously.
When Canstar Blue might suit you
If retailer reputation and customer-satisfaction ratings are what you most want to check (especially if you have been burned by poor service before), Canstar Blue is a genuinely useful resource, and its star ratings are a good input into any switching decision.
Choose EnergySorted when you want the precise cost for your household rather than an average rating, whole-of-market coverage, independence from retailer commissions, and ongoing bill tracking. Better still, use both: check a retailer’s reputation on Canstar Blue, then let EnergySorted tell you exactly which plan is cheapest for your real usage.
