Join Mercury online

If you are contacting us for the first time, or if you've previously been a Mercury Energy residential customer, to join us today you'll need to:

  Set aside around 10 minutes of your time
 
  Tell us your address
 
  Let us know your property's meter number and ICP number (which can be found on a current electricity bill)
     
  Give us some information about yourself
 
If you do not have all the required information, your form can be saved part way through, which allows you to return at a later time to complete the process.

Simply click the ‘Exit form and complete later’ button when it appears and we’ll send you an email with information on how to return.

If you require help during the process, use the tips in the right hand menu or click any underlined text for an explanation.
