How to File Your UK Confirmation Statement (CS01) — 2026 Guide
Every year, every UK Limited Company must file a Confirmation Statement (Form CS01) with Companies House. This is NOT a tax return; it is a “Snapshot” of your company’s administrative details. For Arab entrepreneurs, this is often the most forgotten filing, but missing it can lead to your company being “struck off” (closed) by the government. In 2026, the process is fully digital and takes less than 5 minutes if your records are organized.
In this guide from Eteform.com, we explain what the CS01 is and how to file it correctly.
What is the Confirmation Statement?
The purpose is to confirm that the information Companies House holds about your company is still accurate. It includes:
- Registered Office Address: Where the company is legally located.
- Directors: Who is currently running the company.
- Shareholders: Who owns the company and how many shares they have.
- PSC Information: Who are the Persons with Significant Control.
- Standard Industrial Classification (SIC) Code: What kind of business you are doing.
The Strict Deadline
You must file a Confirmation Statement at least once every 12 months. You have a 14-day “grace period” after the anniversary of your incorporation to submit it.
How to File Your CS01 (How-To)
Step 1: Check Your Data
Log in to your Eteform dashboard or the Companies House portal. Review all the current details. Have you changed your address? Has a partner left?
Step 2: Update if Necessary
If details have changed, you must file the update forms (like AD01 for address or AP01 for directors) before or at the same time as the CS01.
Step 3: Pay the Government Fee
There is a small annual filing fee paid to Companies House. At Eteform, we include this fee in our CS01 Filing Service.
