Hello Richard
If you are a director of one company and then leave to set up a new business, you have to be very careful about the "look and feel" of the new company. If you set up a new business which is basically the same as the old one, then this could be seen as stealing the assets or goodwill of the old business.
It is possible to set up a Phoenix company but you would need to buy the assets and good will (for example the name) before this can happen. For more information about phoenixing see
