What are 'event-driven notices'?

You must notify Companies House about certain events as and when they happen. The following events include the references and forms that you should use:

A-forms: 

  • AD01 - a change of registered office address
  • AP01 - the appointment of a company director who is an individual
  • AP02 - the appointment of a corporate director 
  • AP03 - the appointment of a secretary who is an individual 
  • AP04 - the appointment of a corporate secretary
  • AA01 - a change of the company’s accounting reference date
  • AD02 - a notification or change of address where the company records are kept available for inspection
  • AD03 - the change of location of the company records to the single alternative inspection address (SAIL) 
  • AD04 - the change of location of the company records to the registered office

C-forms: 

  • CH01 - the change of details (eg the address) of a company director (who is an individual) 
  • CH02 - the change of details (eg the address) of a corporate director 
  • CH03 - the change of details (eg the address) of a secretary who is an individual 
  • CH04 - the change of details (eg the address) of a corporate secretary

T, S and N-forms:

  • TM01 (director) or TM02 (secretary) - the termination of the appointment of a company director or secretary
  • SH01 - for the allotment of new shares
  • NM01 - the change of a company name 

Miscellaneous forms: 

  • a change to the company's total share capital – various forms depending on the circumstances
  • the creation of a charge over any of the company's assets – various forms depending on the circumstances
  • a 'special resolution' or certain other types of resolution being passed by the company’s members – a copy of the resolution(s)

When do these need to be filed?

Forms typically need to be filed at Companies House within 14 days of the change or event but check the Companies House website for any specific requirements.  

You must deliver an application to register a charge to Companies House within 21 days of the creation of the charge to ensure it is valid.

How do I submit the forms?

Most changes can be notified online using the Companies House website or by sending a paper document to Companies House. When you are sending paper copies, you must ensure that you send them to the correct Companies House - the contact details for each Companies House can be found on the government’s website.

Are there any other formalities?

To approve these changes, you should hold a board meeting and make sure that any shareholder approval required is obtained. For more information, read Company resolutions and Board meeting minutes.
