(i) It can lead to imprisonment for up to 2 years and / or a fine [section 13 of the Company Director Disqualification Act 1986].
(ii) That person can be held personally liable for the Company’s debts for the time you acted in breach of the disqualification order [section 15 of the Company Director Disqualification Act 1986].
