A company director will only be disqualified from acting as a company director of a subsequent company if there is proven misconduct in the first company. Companies go bust all the time, it’s a fact of life. Some directors try and trade out of it, when realistically they are just making it worse. But if they acted in such a way as to, for example, make the indebtedness worse, or preferred one creditors over another in paying debts (i.e. trade creditors and not HMRC) then they will be investigated. Disqualification is between 2-15 years.
