While appointing a company secretary is optional for most private limited companies in the UK, many businesses still choose to have one to support governance, compliance, and administrative tasks. If your company decides to appoint a secretary, you’ll need to file Form AP03 with Companies House.
What Is Form AP03?
Form AP03 is the official document used to notify Companies House about the appointment of a new company secretary. It ensures that the appointment is recorded in the public register and keeps your company records compliant with UK regulations.
Note: While private limited companies don’t need to appoint a secretary, public limited companies (PLCs) must do so.
Why Appoint a Company Secretary?
Even if it’s not required by law, there are several reasons to consider appointing a company secretary.
-
Compliance Support: Helps ensure the company meets legal obligations like filing deadlines and statutory documentation.
-
Administrative Management: Manages internal records, minutes, and communication with shareholders.
-
Professional Oversight: Brings experience in governance, especially helpful for growing or investor-backed companies.
