Even if one is not due companies will often choose to file a Confirmation Statement early. 

There’s a number of potentially useful applications:

• A company might choose to submit the Confirmation Statement immediately before or after a particularly complex capital reorganisation takes place. This will provide an updated shareholder list to Companies House.
• After any of share transfers or allotments. This would be beneficial where the company wishes the changes and in particular the names of the new shareholders to appear on the public register immediately rather than waiting until the next confirmation date.  Indeed new shareholders sometimes require this to be done.
• If there is an immediate requirement to update the SIC Code that is shown at Companies House. 
• It allows a company to align the Confirmation Date with other statutory filing dates, particularly accounting dates. There’s no obligation to align accounting and Confirmation Dates in this way, but some companies find it administratively easier.

While making an “early” filing was always possible with the confirmation statement, the fact that Companies House will only charge one statutory fee in any Payment Period (rather than a fee with each and every confirmation statement) makes this option more attractive to many companies.

Note: You cannot file more than 1 Confirmation Statement per day. What does it cost to file a Confirmation Statement?

Important: You cannot file a confirmation statement (CS01) on the same day your company is incorporated. The earliest you can file is the day after incorporation.
