Once a year, every UK company must tell Companies House: “our details on the register are correct.” That's the confirmation statement — form CS01. It's not accounts, it's not tax, and it takes minutes if your records are tidy.
What it confirms
Your registered office, directors, people with significant control (PSCs), share capital and SIC codes. If anything changed during the year, you confirm the updates have been filed.
When it's due
Within 14 days of the end of your review period — usually the anniversary of incorporation. Companies House charges a £50 fee with the filing.
If you forget: late filing is a criminal offence for directors, and persistent failure can get the company struck off the register — at which point its assets, including its bank balance, can pass to the Crown. This is the deadline founders most commonly miss, which is exactly why we email every customer a reminder, free, forever.
How to file it
You can file free-plus-fee yourself through Companies House WebFiling. Or we'll do it for £74.99 including the £50 fee — we pre-fill everything from the register, you review and approve in one click, and we file the same day.
Have us handle it — £74.99
