Wholesale electricity prices have gone through the roof, and smaller retailers are beginning to pass those increases through to customers.
Lumo still have good rates and allow you to lock the price through to 31 August 2023 with a fixed term contract. No exit fees apply.
Rates will vary by area, for Jemena VIC I got quoted:
Service to Property (c/day) 85.800
Anytime (c/kWh) 18.898
Additionally, get $70 cashback from cashrewards via econnex if you're a new customer to lumo: https://www.cashrewards.com.au/lumo-energy . It's not possible to stack a referral code with the cashback.
Offer is available on gas too ($42 cashback) but the quoted rates for me were uncompetitive. YMMV.
Cashback offer expired, still possible to sign up directly. Use the referral system for $50 gift card.
Their prices have skyrocketed on their current market offer compared to the deal at the start of Feb 2022.
They can only change their price once per year, which will most likely be in Jan 2023.
