If you're planning to appoint a new director to your UK company, Form AP01 is a key part of the process. It’s the official document submitted to Companies House to formally record the appointment. 

In this post, we’ll walk you through everything you need to know about Form AP01—from what it is, to how to fill it out, and the most common mistakes to avoid. 

What Is Form AP01? 
 Form AP01 is the official form used in the UK to appoint a new director to a company. It’s submitted to Companies House, the government agency that maintains the official register of companies in the UK. 

🛑 Important: A director’s appointment isn’t legally recognized until this form is submitted. Skipping it could lead to issues for both the company and the individual. 

📝 How to Complete Form AP01 
It might seem a bit technical at first, but once you break it down, completing Form AP01 is quite straightforward. 
📌 Step-by-Step Guide 

1. Company Information 

  • Enter the full legal name of your company exactly as registered. 

  • Add your Company Registration Number (CRN)—you can find this on your incorporation certificate or on Companies House. 

2. Director Details 

  • Input the full legal name of the new director. 

  • Include their date of birth and nationality. Double-check everything against official documents to avoid errors. 

3. Residential Address 

  • List the director’s current and any previous addresses from the last 5 years. 

  • If privacy is a concern, you may provide a service address for public view. However, Companies House still requires the actual residential address for internal records. 

4. Occupation 

  • State the director’s occupation (optional, but helpful for context). 

5. Date of Appointment 

  • Specify the effective date of the appointment. This marks the official start of their role. 

Appointing a new director is a big move—and Form AP01 ensures it’s done right. By following this guide and avoiding common pitfalls, you’ll ensure a smooth and compliant transition. 

Whether you're just starting out or managing a growing company, it pays to get these details spot on. Got questions or need assistance with filing? Don’t hesitate to reach out to a professional for peace of mind.
