What Is a Confirmation Statement (CS01)?
A confirmation statement is also known as CS01. It is an annual filing that must be submitted to Companies House. It confirms that your company’s details on the public register are correct and up to date.
This includes details such as directors, shareholders, registered office details and people with significant control (PSC). If details have changed, they should be updated before you file.
Why Does Every UK Company File It?
Limited companies and LLPs of the UK have a legal duty to file it. This applies whether your business is active, dormant or not trading.
The purpose is to ensure that Companies House holds the correct and current details. Right records help customers, banks, investors and suppliers to trust your business.
Missing a confirmation statement deadline can make your company appear non-compliant. This may create issues for you when you are dealing with lenders.
Who Needs to File a Confirmation Statement?
Many people think that only active businesses need to file it. But in reality, almost every registered company has this obligation.
The filing requirement applies on the size of the company, income or trading status. Understanding who needs to file a CS01 helps you to prevent a late confirmation statement.
1. Limited Companies
Every private and public limited company that registered in the UK must submit a CS01 each year.
Even if nothing has changed within the business, directors still need to confirm that all info remains accurate.
If you fail to meet the confirmation statement deadline, then it can lead to compliance concerns and Companies House action.
2. Limited Liability Partnerships (LLPs)
LLPs are also required to file the CS01. The process is very similar to that used by limited companies.
The filing helps Companies House to maintain accurate info about members and registered offices.
An LLP that misses its confirmation statement deadline may face the same enforcement action as a limited company.
3. Dormant and Non-Trading Companies
Many people believe that dormant companies do not need to file. This is incorrect.
Even if a company has not traded during the year, it must still submit a CS01 and annual accounts where required.
If filing obligations are ignored, a dormant company can still receive the warnings for a late confirmation statement.
Did You Know?
Thousands of dormant companies are struck off each year because directors fail to meet basic filing duties.

What to do if you miss your confirmation statement deadline?
Missing your CS01 deadline is stressful, but it is not the end of the road. The most important thing is to act quickly and not ignore the issue.
Companies House does not usually charge an automatic fine for a missed confirmation statement deadline, but delays can still lead to warnings, strike-off risk and also damage the record of your company. The faster you act, the lower the risk of further action.
1. File your confirmation statement immediately
The first step is to submit your CS01 as soon as you realise it is overdue.
Even if you have missed the confirmation statement deadline, filing now shows the compliance and reduces risk.
Do not wait for reminders from Companies House. A late confirmation statement should always be treated as urgent. Delays can make your company appear inactive or poorly managed.
Pro Tip:
If you are unsure about details, still file first and correct errors later. This is better than waiting and missing your confirmation statement deadline further.
2. Check and correct company details
Before submitting your overdue filing, you have to review all the company info carefully. This includes directors, shareholders, PSC details, office address and share capital.

How the Confirmation Statement Review Period Works?
The review period is the time frame that is used to find when your next filing is due. Understanding how it works can help you to avoid missing a confirmation statement deadline.
Many directors assume that the filing date stays the same every year. However, the review period can change if you file early.
12-Month Review Period
Every company has a review period that usually lasts 12 months. It begins either on the incorporation date or the statement date of the last confirmation statement.
During this period, Companies House expects that records of the company remain accurate and up to date. If you make any major changes in a business then you have to report it when it happens.
Knowing your review period is one of the easiest ways to avoid a late confirmation statement.
How is the Statement Date Calculated?
The statement date is the date on which you confirm that the info of your company is correct and up to date.
All details included in the filing should reflect the position of the company on that specific date. This ensures the public register remains accurate.
The statement date is important because it determines your next confirmation statement deadline.
Filing Deadline: The 14-Day Rule
After the statement date, companies have 14 days to submit their confirmation statement.
If the filing is not delivered within this period, it becomes overdue. Companies House may then begin sending reminders or warnings to you.
Many directors think that they have a full month to file, but the 14-day rule is strict.
Case Study: Missing a Confirmation Statement Deadline
James who runs a small marketing agency in Manchester. The business had been trading successfully for several years. But he became busy managing client projects and overlooked his annual CS01 deadline.
Because the filing only happens once a year, James assumed he still had plenty of time. A few weeks later, he noticed that Companies House had marked his company record as overdue.
The Problem
Shortly after missing the CS01 deadline, James applied for a business loan to support growth of his company. During the lender’s review, the overdue filing appeared on the Companies House register.
The Solution and Outcome
As soon as James realised the issue, he submitted the late CS01 online and also he checked all details of the company for accuracy.
The filing was accepted by the Companies House, and the overdue status was eventually updated.
This simple change has helped him to avoid future issues and maintain a strong business reputation.
Key Lesson:
Even a small filing like a confirmation statement can affect funding applications, business credibility and compliance status if it is overlooked.
