Check the billing period, account details, meter reading and whether the reading is actual or estimated. Review your electricity usage, supply charge, usage rates, discounts, solar feed-in credits, concessions and any late fees or adjustments, then compare them with your previous bill. Confirm the due date and payment options, and contact your retailer if anything looks incorrect or unexpectedly high. If you think you may qualify for an energy concession, check the relevant state or territory government website.
