Thanks for replies, Guys. I'll use your advise for any future correspondence. Here's how the latest attempt to start all over again has panned out. Note how they have told me initially that the matter is urgent, I need to contact them by phone straight away. It's so urgent that I can provide a number and have them phone me. Note also how they drip feed the "urgent" information over a period of almost 2 weeks...

Thanks for that. Did you catch my post previous to yours? I'm pretty certain I don't owe this debt.

** Update ** I think they are both the same company, they've decided to chase the debts separately. Also, they were my supplier prior to when I moved the tenant in. It looks like the tenant has moved out without telling them, and they've simply tried to saddle the debt with the previous account holder. The gap between the tenant's last occupancy and the point of sale is approx 6 weeks. Strangely, the supply period that the utility company is chasing me for is 7 or 8 months after I sold the property. I honestly don't know where I stand here.

Thanks. It's actually 2 debt companies, one for gas and one for electricity. I've actually just noticed that it appears to be 2 different utility companies: Scottish Hydro Electric Gas (pastduecredit) and Scottish Southern Energy (BCW Group – an arvato company). That's 2 separate suppliers, yes?

Hi, I wonder if any of you guys could provide an email template for me to send? Short version of events as follows : I owned a property. I leased it out from Oct 2010 and never lived there again. I sold the property in April 2013. I have had a utility company demanding £800 for the supply of electricity and gas. I have never had an account with this company. The date of supply is from 16-12-2013 to 17-12-2013, yes you read that right... £800 for utility supply for 24 hours... 8 months after I've sold the property. I explain all this to the debt company. They put "my" case on hold. About a month later, the process repeats itself. This has been going on for around 9 months. I sent them evidence of sale when they first contacted. After that I'm thinking, why do I need to prove that I didn't live somewhere anyway? Surely the burden of proof is on them? I also questioned how they could justify £800 for 24 hours supply, and that if I did live there I wouldn't be paying that bill anyway... They then say... "Fair point, we'll put your account on hold and get back to you." One month later.... "We are contacting you because you owe our client £800 for the supply...." Question is, where do I stand? How do I get them to stop harassing me? TIA
