Chased by a utility company?

Hello, cutting a long story short. Out of the blue, I received an unexpected electricity bill from Scottish Power for £1233 (interest and debt costs added) going back over 4 years in relation to a commercial property I rented out.

It would appear that the tenant may not have paid for his electricity. Bearing in mind over this time I had not received any correspondence from Scottish Power, no emails, letters or any type of correspondence. It’s now got to the point that the Debt Company has instructed Solicitors with the view of Court Proceedings.

I don’t as far as I am aware have contact with Scottish Power my details were obtained through Companies House. If this sort of thing has happened to you where do I stand? Am I liable for somebody else’s bill as the owner of the property or are they trying bullying tactics to get me to pay?

Thanks,

David
