CH03 – Change the details of a secretary Downloadable PDF Form – Print & Post

Form CH03 is specifically used to facilitate the changes relating to company secretaries.

CH03 form is similar to the CH01 document. The retired 288c form was changed to four different distinct documents in recent years. The advantage of this change is that there are less irrelevant boxes and sections and because of this, Companies House now rejects less submissions due to incorrect or incomplete forms.
