What is a confirmation statement?

A confirmation statement is the annual filing UK limited companies and LLPs submit to Companies House to verify that the public register holds accurate company information. It replaces the old annual return (form AR01) and is filed on form CS01 for companies or LL CS01 for LLPs. It is separate from annual accounts and the corporation tax return as these are three distinct filings with three different deadlines. Filing a confirmation statement does not involve any financial information; it is purely a register-of-companies update.

What's included in our confirmation statement filing service?

Our confirmation statement filing service covers the full CS01 submission process, from reviewing your existing Companies House record to confirming acceptance with you by email. You provide the latest details for any changes, and we handle every step of the submission.

Review of your existing Companies House record

Before filing, your current Companies House record is reviewed to identify any details that may need updating. Common items checked include directors and secretaries, registered office address, registered email address (mandatory since March 2024), shareholders, share capital, and SIC codes describing the nature of business.

Updates to directors, shareholders and PSC information

Any changes to directors, shareholders, or people with significant control (PSCs) are submitted as part of the confirmation statement. Where appointments, resignations, or PSC changes need to be filed separately on forms AP01, TM01, or PSC01, we file those alongside the CS01 to keep your record fully current.
Read More

SIC code review and changes

SIC codes describe the nature of your company's business and are confirmed each year on the CS01. Where your activities have changed, new SIC codes are selected from the Companies House list and submitted with the confirmation statement.

CS01 form preparation and submission

The CS01 form is prepared with your confirmed details and submitted online to Companies House through our authorised agent account. Submission is usually accepted within minutes; in practice, the digital service rejects only filings with incomplete identity verification or unresolved register inconsistencies.

Companies House £50 filing fee handled for you

The £50 Companies House digital filing fee is paid as part of our service and itemised on your invoice. You do not pay Companies House directly, one invoice covers both the service fee and the statutory fee.

Who needs to file a confirmation statement?

Every entity registered at Companies House whether trading, dormant, or recently incorporated must file a confirmation statement at least once every 12 months. Filing is a legal requirement under section 853A of the Companies Act 2006, and there is no exemption based on size, turnover, or activity.

Active

Active limited companies

Active limited companies file a confirmation statement annually to confirm directors, shareholders, PSC details, and registered office. The statement is filed in addition to annual accounts and the corporation tax return, on a separate deadline.

Dormant

Dormant limited companies

Meet at least two of three thresholds. File simplified micro-entity accounts under FRS 105 with Companies House and a full CT600 with HMRC. Micro-entity status reduces disclosure requirements.

LLPs

LLPs and other Companies House-registered entities

Limited liability partnerships file a confirmation statement on form LL CS01, covering members, designated members, and PSC details. Community interest companies (CICs), limited partnerships, and Scottish limited partnerships have equivalent annual filing obligations.

When is your confirmation statement due?

The confirmation statement is due once every 12 months, with a 14-day filing window after the end of each review period. Companies that miss the window face strike-off action, not financial penalties, which makes the deadline more urgent than late accounts filings in practical terms.

Your annual confirmation date explained

The confirmation date is the anniversary of your company’s incorporation, or the anniversary of your last confirmation statement, whichever is later. A company incorporated on 15 June 2024 has a first confirmation date of 14 June 2025 and an annual filing window opening on that date each year.

The 14-day filing window after the review period

You have 14 days after the confirmation date to file the statement. Filing on the confirmation date itself or earlier is permitted. The 14-day window is firm as Companies House does not extend it for individual companies.

First confirmation statement after company formation

A newly incorporated company files its first confirmation statement no later than 14 days after the first anniversary of incorporation. The first confirmation statement is identical in form and content to subsequent statements; there is no simplified version for new companies.

mandatory for all UK companies since March 2024 under the Economic Crime and Corporate Transparency Act
Identity verification at Companies House became mandatory for new directors and PSCs from 18 November 2025, with a 12-month transition window for existing officeholders ending 18 November 2026. Verified ID details must be on file before any confirmation statement involving director or PSC changes is filed.

Can you file a confirmation statement online?

Confirmation statements can be filed online and most are. Companies House accepts digital CS01 submissions through its WebFiling service or through authorised agents like MicroFiler. Online filing has three advantages over paper:
Filing through an authorised agent removes the need for company directors to maintain Companies House WebFiling accounts, presenter codes, or authentication codes. Submission, payment, and confirmation are handled by the agent and confirmed back to the director by email.

What happens if you don't file a confirmation statement?

Failing to file a confirmation statement triggers Companies House strike-off action against the company. Unlike late accounts, late confirmation statements do not attract direct financial penalties, but the consequences are more severe which can be loss of the company itself.

Companies House strike-off proceedings

Companies House issues a first warning letter shortly after the 14-day filing window closes, followed by formal strike-off action under section 1000 of the Companies Act 2006. A notice is published in the Gazette giving two months’ notice of intended dissolution. If the confirmation statement is not filed within that period, the company is dissolved and removed from the register.

Director personal liability and disqualification risk

Directors of companies struck off for non-filing can face disqualification proceedings under the Company Directors Disqualification Act 1986. Disqualified directors cannot act as a director of any UK company for the period of disqualification, which ranges from 2 to 15 years.

Loss of company assets to the Crown (bona vacantia)

Once a company is dissolved, all remaining assets including bank balances, property, intellectual property, debtors and pass to the Crown as bona vacantia. Recovering assets requires court-ordered administrative restoration, which takes 6 to 12 months and incurs legal fees, restoration fees, and back-filing costs that typically exceed several thousand pounds.
