I think you have a misunderstanding about fixed rate energy contracts. Fixed rate means that the cost each unit (or kWh) of electricity and gas that you use will remain the same for the period of your contract, however the amount you are charged each month will change depending on how many units (kWh's) of electricity and gas you use. In general you will use less in the summer (and your bills will be lower) and more in the winter (your bills will be higher).
I hope this helps.
