No, You have the flexibility to choose any energy supplier you prefer. Our services are independent of your energy supply arrangement. However, we highly recommend considering a time-of-use tariff. By switching to a time-of-use tariff, you have the opportunity to further enhance your system returns. This tariff structure allows you to take advantage of different pricing rates throughout the day, enabling you to optimise your energy consumption and maximize your savings. While the choice is ultimately yours, we believe that a time-of-use tariff can provide you with even greater benefits and help you make the most out of your residential battery system.
