Assuming it is a residence then no - they must get a County Court Judgement & you would be notified of their claim by the Court. You would have an opportunity to defend the claim, & to make an offer to pay by instalments. If you comply with whatever judgement the Court makes then the creditor cannot get a charging order. If you do not comply they can get an interim charging order and this is often done without you being notified in advance. But there has to be a Court hearing before the interim order becomes final, and you will be notified of that.
However, if the creditor does not know your present address all the above could happen without you being aware of it - their responsibility is to send documents to the last known address.
