Compare the estimated annual cost for your usage, not just the headline discount, and check supply charges, usage rates, conditional discounts, contract terms and any exit fees. If you have solar, review the feed-in tariff and how it applies to your exported energy. Plans and retailer availability vary by state, meter and household circumstances, so use Energy Made Easy or Victorian Energy Compare where applicable, then confirm details in the retailer’s fact sheet. If you are worried about paying, ask the retailer about its hardship program before switching.
