The 'made up to' date of your confirmation statement is typically one year after the date of incorporation of the company, with a due date of 14 days after that. It is mandatory to submit a confirmation statement to Companies House at least once annually.

However, if there are any changes that need to be reported to Companies House, it is recommended to file a confirmation statement after the changes have been completed. By doing so, the due date for the confirmation statement will be modified, as it will be considered an "early" filing. The confirmation statement 'made up to' date will change to a year from the date of the last confirmation statement filing, with the due date being 14 days after that.

The 'made up to' date is the final date to consider, when working out what changes need be filed at Companies House. 

Example:

If the company’s 'made up to' date is 1 February 2024, the confirmation statement due date will be 15 February 2024. This means that any changes that were made to the company up until 1 February should be noted in the confirmation statement that is to be filed by 15 February.

If a change took place within the company on 2 February 2024 or later, that would need to be filed in the next confirmation statement, as it was done after the confirmation statement 'made up to' date.

If you’re in doubt, you can find a company’s confirmation statement due date by searching for the company on the public record at Companies House. The first date shown is the confirmation statement 'made up to' date, and the second date is the confirmation statement due date.
