I always ask the same question, 20% of what and how long will it last? so many adverts on TV offering different discounts but no one seems to quite manage and offer a deal that shows the bottom line cost to you. In the case of say AGL it's all on their website.
Good luck in your search, for me I am locked into the VPP here in SA for my electricity, despite that, the deal and the FIT are worth a lot to me.
Thanks for getting in touch!
As BWSS stated, details regarding our current discounts are listed on agl.com.au. However, it's always worth checking in with our web chat team (aglener.gy/ChatCom) to see if there is anything else that we can do to ensure that you're saving as much money as possible!
