If you are suspected of fraudulent or wrongful trading, action may be taken against you which could lead to criminal prosecution, a fine, and/or disqualification as a director. If you have personally guaranteed the company's debts, you will be required to honour those guarantees. You could also face personal insolvency and possibly bankruptcy proceedings, if you are unable to pay.
Otherwise, however, there should be no significant consequences. You can continue to act as a director of other companies (though your credibility may suffer). For the next five years, however, you are not allowed to be a director of another company with a similar name without the court's permission. (This helps to prevent unscrupulous directors of failed companies from setting up a so-called 'Phoenix' company which then carries on in the same line of business without being obliged to pay back the original company's creditors.) If you wish to trade under the same name in a new company, there is a procedure to be followed which will enable you to do so. You should seek specialist legal advice.
