The confirmation statement (CS01) confirms every year that your company’s details at Companies House are correct. In the app you have two options: ask Aiden to file it or do it yourself on WebFiling, the Companies House website.
When it’s due
According to gov.uk (checked on 11 November 2026), you must file at least one every 12 months, and you can file up to 14 days after the review period ends. The Companies House fee is £50 online, according to its «Companies House fees» page. Your date is in Taxes, under Your calendar.
Have Aiden file it
- In Taxes, tap Confirmation Statement (CS01) in your calendar
- Tap Have Aiden file it
- Under Shall we request it?, tap Request it. A support ticket opens and you’ll see Request sent
- An Aiden accountant prepares it and replies in the ticket, which you follow in Settings → Support → Contact support
As the app says, nothing gets filed or paid without you confirming first.
Do it yourself
- In Taxes, tap Company and, under Important dates, tap Confirmation Statement (CS01)
- Tap File it myself (WebFiling): Companies House WebFiling opens
- Sign in with your company authentication code, check directors, PSCs, capital and activity, and file
How to get the code: verify your identity for Companies House. So that Aiden can file, save your codes in the app: how to save your Companies House codes.
