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.
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.
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.
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.
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.
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.
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
Dormant companies must file a confirmation statement every 12 months regardless of trading activity. No accounts or financial information are required on the CS01.
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.
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.
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.
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.
Filing a confirmation statement through MicroFiler costs £140 including the £50 Companies House digital filing fee, billed as a single invoice. The fee covers a full year’s filing, including any additional confirmation statements within the same 12-month payment period.
No hidden extras. The fee covers CS01 preparation, review of your Companies House record, and direct submission. There are no extra charges for SIC code updates, PSC changes, or filing confirmation.

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.
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.
Once a company is dissolved, all remaining assets including bank balances, property, intellectual property, and debtors 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.
No. The confirmation statement (form CS01) replaced the annual return (form AR01) on 30 June 2016. The CS01 is a confirmation rather than a full return, directors confirm that existing details are correct, updating only what has changed.
Yes. Dormant companies are required to file a confirmation statement every 12 months, regardless of trading activity.
Yes. Filing early is permitted and resets the next confirmation date to the date of filing. Many companies file 30 to 90 days before the deadline to avoid year-end pressure.
The confirmation statement is still required, even when no details have changed. The filing confirms that the existing information is accurate.
Once your details are confirmed, the online submission and Companies House acceptance usually complete within a few minutes. Our end-to-end turnaround from instruction to confirmation is typically 3-5 working days.
A SIC (Standard Industrial Classification) code identifies the nature of a company’s business in five digits. Existing SIC codes are listed on your Companies House public record; new codes are selected from the official SIC list, which Companies House publishes online.
No. They are independent filings with separate deadlines. The confirmation statement deadline is 14 days after your confirmation date; annual accounts are due 9 months after your accounting reference date. The two dates rarely align.
Errors can be corrected by filing a second confirmation statement within the same payment period at no additional Companies House fee. Material errors involving PSC or share capital changes may also require dedicated forms (PSC01–PSC09 or SH01) filed alongside the corrected CS01.
Yes. We can file confirmation statements for newly acquired companies once we are appointed as your authorised agent and identity verification is complete. Bringing the public register up to date on directors, shareholders, and PSC details is part of standard onboarding.
A confirmation statement (CS01) confirms the register annually. A director’s appointment (AP01), resignation (TM01), or change (CH01) is filed at the time of the change. We file both appointment changes within the year and the CS01 to confirm the position annually.
