After not billing us for 18+ months we got a huge bill mid-last year. We had an odd 2-meter setup and had one removed because we wanted to switch companies. 8 months on they still cannot update the meter record and so we cannot switch. We seem locked into nPower whatever we try and stuck on the standard tariff. And now they are not billing again so we expect another large bill in, I dunno, 2 years time maybe. We want to switch to dual fuel with another provider but no chance - tried uSwitch to SSE and got told that as we have a non-standard meter setup (because nPower cannot change the data!) we cannot switch. How difficult can it be! I wonder if this Omid Djalili guy knows exactly what he's put his face on...
