There could be multiple reasons for the change you're seeing, such as a meter change, a tariff change, a change in your rate structure etc. As a result, there is no one simple answer I'm sorry to say! However, you're welcome to get in touch with our web chat team (aglener.gy/ChatCom) who'll be happy to look into things for you further!
If I’ve helped in anyway, please mark my post as SOLVED!
