I got a new meter installed on 26 November 2020, as my old one was faulty! The old one was a top up meter using a credit key. My new one is a credit meter & has no key, so how do I pay my bill before it gets out of hand? I just have to pay December & January as I got a email from a Bulb engineer (yes they do exist) telling me the meter has gone into safe mode & I would not be charged until the engineer visit. I also have a excel sheet I designed to tell me the cost as I take weekly readings, & they are way out. Do credit meters run on a different tariff that top up meters?
Thanks for any help
