I originally started with First Utility who for the short time I was actually with them they seems great. It all went down hill as soon as Shell took over. They upped my bill as they said I was using more than I’d previously said, I tried to argue that with it being winter and the heating is on we do but in summer we use a lot less. So over the year it evens out. They didn’t agree and so doubled my monthly payment. Then I had a smart metre fitted, which shows on the remote display unit I use roughly what I’d always thought I did. Tired to call shell and can never get through and even though they metre reading is sent to them daily they still seem to think I use more than I think I do. Again tried to call to see if the remote unit is wrong or the metre has an issue or they’re wrong but can never get hold of anyone. My renewal is due so I’ve switched and hopefully will have better service from E-On. I’d never recommend Shell to anyone and I’d never use them again.
