It started in 2006 with a bill for 15p gradually rising to £16.19 in Sept 13 - all of which I ignored then the next bill in Dec 13 was for £571.76 at which point I pointed out that they did not supply the property. Here is the letter I sent in Feb 14.
"I refer to your latest communication dated 3rd February. Please note that the statement “For energy supplied at Flat 7 Temple House EN7 5HY is not correct; you do not supply any energy to that address. The fact of the matter is, as you have been told many times, that this meter is in a garage which is seldom used and there is a separate supply to the residence which is some 100 meters or so from the garage.
I have tried on a number of occasions to provide a meter reading and you refuse to accept it. Your constant manoeuvres are now at the point where I can regard them as nothing short of harassment. Not only do I get ridiculous bills but you constantly demand that for “health and safety reasons” I need to have the meter changed; given that no attempt has ever been made to change the meter in my residence I have to assume this is all part of the harassment campaign.
The electricity in the garage is currently turned off, as it has been for some time, and the meter reading is “0000 1.22” and so, if anything, I suspect that you owe me money so if you want to pursue the matter please feel free I’ll see you in court and counter sue for harassment.
I await your comments with interest."
Hope this helps.
It was after that that I received the letter confirming that they agreed they were not the supplier and advised me that the account was removed and the account closed.
