I’ve just received a letter through the post addressed to someone else but at my address. However in the details it has my name and old address and is asking for £1153 HB overpayment from Jan 2012 
I was on HB at that time but this is the first I have ever heard of an overpayment. Isn’t there some kind of time limit on how long they can chase a debt?! Shouldn’t they have told me about this before?
