1. Find a comparison website (e.g. run by the government like Victoria's Energy Compare) https://compare.switchon.vic.gov.au
Try another comparison site, for a 'second opinion' (e.g. Canstar).
2. Find the cheapest provider. Check other discounts for Direct Debit payment, Percentage off Usage and/or Supply Charges. No exit fees? No credit card surcharge? Electricity/Gas Combo Deal?
3. The new provider will do the rest.
4. You may get a better counter offer in the mail from your old provider (see below). Previously my old provider's best discount was 35% off electricity usage and 20% off gas usage. The "jumping ship" offer to stay was 46% off and 35% off respectively!
They even sent me a letter addressed to my new provider to facilitate the cancellation of the new contract.
5. Final decision
I am staying with the new deal (Globird Energy) as it has no exit fees. It must be a good deal if the old provider can offer such an attractive counter deal. Be prepared to swap again if you are not satisfied.
