For micro entities operating in London, staying compliant with Companies House is essential. One of the most important annual legal obligations is confirmation statement filing.
Whether your business is newly incorporated or already trading, confirmation statement filing for micro entities in London ensures that your company information remains accurate and up to date on the public register.
Every UK company, including dormant and non-trading businesses, must file a confirmation statement at least once every 12 months. This requirement applies equally to micro entities, small limited companies, and startups based in London.
In this guide, we explain everything you need to know, including filing deadlines, costs, legal requirements, and why professional filing support can help avoid penalties.
What Is a Confirmation Statement for Micro Entities?
A confirmation statement, also known as form CS01, is an annual filing submitted to Companies House.
Its purpose is to confirm that the company details held on the register are correct.
This includes:
- Registered office address
- Directors’ details
- Shareholder information
- People with Significant Control (PSC)
- SIC codes
- Share capital details
- Registered email address
It is important to understand that this is not the same as annual accounts.
Micro entity accounts relate to financial reporting, whereas the confirmation statement is an administrative compliance filing.
This distinction is highly useful for external linking with related anchor terms such as:

- limited company compliance services
Who Qualifies as a Micro Entity?
A micro entity is a very small limited company that meets at least two of the following conditions:
- Annual turnover of £1 million or less
- Balance sheet total of £500,000 or less
- 10 employees or fewer
These businesses often include:
- consultants
- freelancers
- contractors
- e-commerce startups
- service-based agencies
- local London limited companies
Even though micro entities benefit from simplified accounts, the confirmation statement requirement remains mandatory.
Why Confirmation Statement Filing Matters in London
London businesses operate in one of the UK’s most competitive markets.
Missing a confirmation statement deadline can lead to:
- financial penalties
- legal compliance issues
- company strike-off risk
- director reputation damage
- difficulties with banks and lenders
Companies House may begin the process of removing your company from the register if the filing is not completed on time.
For businesses seeking funding, partnerships, or corporate credibility, maintaining a fully compliant company profile is essential.
This makes professional confirmation statement filing services in London highly valuable.
When Must Micro Entities File Their Confirmation Statement?
A confirmation statement must be filed once every 12 months.
The filing deadline is usually:
12 months after incorporation + 14 days
For example:
If your company was incorporated on 10 April 2025, your filing deadline would be 24 April 2026.
Many London business owners confuse this with annual accounts deadlines.
A useful external link anchor here could be:
- annual accounts filing deadlines
- Companies House compliance calendar
What Information Should Be Checked Before Filing?
Before submitting your CS01, review all company records carefully.
Directors and Officers
Ensure all appointments, resignations, or changes are updated.
Shareholders
Verify current shareholding percentages and issued shares.
PSC Register
Confirm details of anyone with significant control.
SIC Code
Update your business activity code if your services have changed.
Registered Office
Ensure your London registered address is still correct.
Changes to certain records must be filed before submitting the confirmation statement.
