Compare the full offer, including usage and supply charges, discounts, contract terms, payment methods and any exit fees—not just the advertised price. Check whether your current plan has a fixed-term contract, and keep your account details and meter information handy for the new retailer. Your new provider will usually arrange the transfer, while your old provider sends a final bill; your electricity or gas supply should generally continue without interruption. If you receive a concession or have an embedded-network arrangement, confirm how switching may affect you with the relevant provider or government department.
