Moved into a property with Spark Energy as the supplier?

Spark Energy may be the preferred supplier for your rental property, which means that your new home has already been set up with an account with your details.

Typically, these details would have been passed on by your letting agent to Spark Energy as part of the terms of your lease agreement — and authorisation to do this will be outlined in that agreement. You can check your copy of your lease to confirm this is the case.

You should be aware that it is within your rights to switch energy supplier, even if your property has a preferred supplier, and you have signed a lease agreeing to the preferred supplier.

For more information on switching energy at a rental property, read our Tenants’ Guide to Switching.
