Avoid !!! Avoid !!! Avoid !!! They are insane, they operate in fantasy land. I don't even buy energy from them, but they are billing me. Spend hundred off hours in "trying" to talk to them, as I don't have an account with Npower they will not talk to me. But it has not stopped them Serving Court papers on to me for money for current used energy of site, of which I pay at a different energy company. Even UKnetworks say they have no rights of claim to my energy meter. Even the energy company I pay, have written to Npower to tell them to stop billing me. Npower's complaints procedure is not to reply to you, if you poke a worker to put an internal one for you, Npower will just sent out a dead lock letter with no explanation. Zero stars, infact negative star review. Do not get mixed up with Npower, they have not got a clue let alone energy. Npower are total lairs, incompetent and insane. Make sure you record all communication with them. Also note staff regularly swear at you, and hang up Expect over a hour in queue when phoning them. Npower see you in Court.
