Also if the company is liqudated (Or placed in administration) you can write to the administrator and DTI as a creditor, demanding further investigation into the conduct of the directors of the company.
If any of them are found to have prejudiced the creditors or the operations of the company in any way, then they can be struck off as directors, and found personally liable.
FYI if you are owed a salary at the time of the company being foreclosed, you are a creditor (It still owes you money).
