One of the worst companies I've ever used. We live in a small flat as a couple and we have been charged £500 this month. This has been going on since we moved in despite the cost of living. In the summer our bills were hitting £150-£200 at times. The meter was broken and overcharging us, it got replaced and now it's got worse. They want £120 to check this meter when it's clearly broken. We are now getting the energy ombudsman involved so we will see what happens. They also took two payments out £433 and £366 for one month and then I had to call up and ask for one of them to be refunded.
