I would shop around and call for prices, they are all different all the time different discounts for new customers and specials don’t assume what was cheapest is still cheapest. I’m with Redenergy but called them to ask for a better rate and they price matched Give your current supplier at call

Energy Australia i pay $500 each bill not bad for a family of 6

Shopping around as suggested by other ‘answers’ is a good idea.

Ask for best deals from other companies and then take those to yours you can save heaps doing this.

It pays to call them and ask for a better deal and threaten to walk unless they can offer you something better.

I imagine it would depend on where you live and the best deals that can be put in place for your usage.
Maybe use an online comparison guide to obtain all relevant information and compare providers and prices.

I have AGL, they give a discount if it’s paid before the due date. But now they’re prices have increased.

My mum is with Energy Australia she says they’re cheap.
Maybe use I select to compare that might be helpful

Do some research and ask anyone you know like a family member or friend. But I like AGL they have been a good energy company to me.

I think it depends on where you live. I am in WA, I am with Alinta and I never had any problem with them.
