Your bill is made up of 3 key things
The Sero Life optimisation charge - this is 40p per day and pays for all of the Sero Life services
Your energy usage - This is the total amount of energy you have used from Octopus energy, we estimate this based on your comfort settings and pay Octopus on your behalf. We monitor this closely, to make sure you aren't paying too much (or too little) and we will show you that you have not paid a penny more than you should for your energy usage.
Electricty standing charge: this is the cost of Octopus energy providing an electrical connection to your home, you pay this to us, we pay Octopus on your behalf and don't add to that charge.
To make budgeting easier we base our estimates across the entire year and then divide that amount into 12 equal monthly payments. That means you are paying for more than you use in the summer months, but it means your bill wont go up in the winter.
