We work out your personal projection based on the following: 

  • Usage information you provided when you applied to us
  • The size of your home
  • How many people live in your home
  • Any usage information from your previous supplier (if available) 

 

When you're changing your tariff, the personal projection assumes that you’ll use the same energy as last year, and doesn’t include any future or current debit or credit balance on your account.
