First Utility (FU) also go under the name of Shell. I was moved to shell by OFGEM following the failure of Green. In 2017/18 I was a customer of First Utility and left. They supplied a smart meter at that time but my new suppliers did not use these hence I sent in manual readings. Now they are telling me I have been reading this meter incorrectly and it is nearly 3500 units less than I have paid to my previous suppliers. Completely untrue!!!! I know and have been shown how to read a smart meter and both companies before shell have accepted these readings in fact my final reading with First Utility ties up with my current reading. However when I leave FU my meter will show an appx 3500 more units than FU are currently saying my meter reads. Hence I will have to fight to show the FU reading is wrong and I have paid other suppliers for these units and they changed my readings to suit what they say my meter is reading. Their reading is no where to be read on my smart meter. This company was bad 5 years ago and nothing has changed. Thanks a lot OFGEM!!!!
