What is a confirmation statement (CS01)?

A confirmation statement (filed on form CS01) is how a company tells Companies House, at least once a year, that the information on the public register is still correct. It replaced the old annual return in June 2016.

What it confirms

It is a check, not a re-submission. You confirm that the following are up to date: registered office, directors and secretaries, people with significant control (PSCs), shareholders and share capital, and the company’s SIC codes (what it does). If anything has changed, you update it — some changes are made on the statement itself, others must be filed separately first.

When it is due

Each company has a review period (usually 12 months from incorporation or from the last statement). You have 14 days after the review period ends to file. You can file earlier and start a new 12-month cycle.

Why it matters

Filing is a legal duty. Persistently failing to file is a criminal offence and can lead to the company being struck off the register. In Compaxit, the confirmation-statement due date appears on your dashboard deadlines so you never miss it.
