Hi @JemimaBottle
The Core plan is the default plan that applies to your account when your existing 12-month plan is about to expire. Once the current plan ends, the Core plan is automatically added to your account.
For more detailed information or to review other available plans, it’s best to visit our website at https://www.agl.com.au/residential/energy/compare-plans or call us on 13 12 45. One of our dedicated agents will be happy to assist you.
