Good luck Nick with companies house, it can take months for the receivers to put details forward.

A winding up order may have been serve'd on them if so ring the local courts and they my be able to tell you who the liquidaters/receivers are.

Its also very difficult to bring criminal chargers against a director who has blatantly traded insolvent, unless it is exceptional they wont bother and just ban them from being a director again.

Good Luck
