When you sign up to Bunch you agree a monthly payment which will be same for each month - unless there is over usage on the account.
This means that although we are aware that less energy will be used in the household during the summer months the payments that you make will remain the same.
Your allowance given covers the summer and winter months. We don't increase the payment in winter when you are using more but they also do not reduce in the summer either.
This makes budgeting for your energy easier. Most energy companies work on one monthly fee across the course of the year.
Also remember if you do not use all of your allowance in your contract this will be credited back when your contract ends.
