I have been with them 5 yrs now but for some reason just lately my electric is using £30 aweek. I did get in touch with them n it went down on how much it was using but then realised it went back to how it was. Other than that I did really like using this one n I would of stayed with them. Now I have switched because of that. The person under me using the same amount of electric as me but only spends £20 every 2 weeks n there is a plus I can have my home warm discount on my gas Or my electric but with them they split it n put half on each one. I did recommend other to join without refer a friend I just told them about it. Now if they seem to using more I be recommending they switch again
