Check that your property has a compatible smart meter and confirm the retailer’s peak, shoulder and off-peak hours, including weekends and public holidays. Compare the usage rates, daily supply charge, controlled-load arrangements and any discounts with your current plan. Review your past bills to see when you use the most electricity, and consider whether solar panels, a battery or shifting appliances could change the result. Use the retailer’s comparison estimate and Energy Made Easy, then ask the retailer to confirm any meter or plan changes before switching.
