When comparing smart meters, check whether the meter supports interval data, remote readings, outage detection and solar or battery connections. Also compare the electricity plans available with each meter, including time-of-use rates, daily supply charges, solar feed-in tariffs, contract terms and any installation or exit fees. In some areas, your retailer may arrange the meter installation, while the distributor remains responsible for the network equipment. Ask the retailer for a written quote and confirm how your usage data is collected and used before switching.
