Have a look at Section 32 of the Act:
Postponement of limitation period in case of fraud, concealment or mistake
(1) Subject to subsections (3) and (4A) below, where in the case of any
action for which a period of limitation is prescribed by this Act, either--
(a)
the action is based upon the fraud of the defendant; or
(b)
any fact relevant to the plaintiff's right of action has
been deliberately concealed from him by the defendant;
or
(c)
the action is for relief from the consequences of a
mistake;
the period of limitation shall not begin to run until the plaintiff has
discovered the fraud, concealment or mistake (as the case may be)
or could with reasonable diligence have discovered it.
References in this subsection to the defendant include references to the defendant�s agent and to any person through whom the defendant claims and his agent.
Moving house and not telling the Finance company is concealment. As said, debt does not conveniently just go away and a lot of lenders will pursue you until they have their money.
Most finance companies have their own in house solicitors / legal department and are well aware of the law and do not commit fraud (unlike a lot of people on AB)
As I mentioned, when you do eventually resurface, there will be lenders out there who will get Attachment of Earning Orders placed on you (and hopefully this will embarrass you to your payroll department)
