I have recently moved house and changed energy supplier and got my final letter in from SP saying that I have the aforementioned bill still to pay for my electricity (Gas is in £25 credit).
This had occured nearly 3 years ago where they sent me a similar bill. As it turns out it was from a previous tennant who racked up a bill. I then had to get my landlord at the time to call them (with my permission) and enquire about this. From what I remember is that a code had to be sent out for the new tennant, which didn't happen, and that I had to just go to my local shop with the key and it would register. All done.
Fastforward to now and I get a letter in from SP to my new address saying that I have a bill of £330.10 still to pay for my electricity. I imagine that the previous tennant might have had a direct debit set up with them because I don't understand how I can rack up a bill on a pay as you go tariff.
I'm just waiting on a callback from SP and was just wanting to know if something similar has happened to anyone else, and if so how it got resolved.
Thank you for reading.
From what you say it is a historic debt from an old tennant. This happens a lot, but SP should be able to clear you from any involvement. Anyone taking on a new PAYG should always register as a new tennant with no connection to previous users.
