Running a UK limited company means dealing with Companies House at some point, and for most directors that means working out which form to file and when. Whether you are appointing a new director, issuing shares, changing your registered office or filing your annual confirmation statement, getting the paperwork right matters.
Errors can lead to rejected filings, late penalties, or a public record that does not reflect the real position of your company. This page walks through the main Companies House forms you are likely to come across, what each one does, and the practical points worth knowing before you file.
If you want to talk through a specific situation with someone who has seen it all before, our telephone guidance line is the fastest way to get clarity.
What this document is
Companies House is the registrar of companies for the United Kingdom. It holds the public record for every limited company, LLP and certain other entities registered in England and Wales, Scotland, and Northern Ireland. The register is open for anyone to search, which is why keeping it accurate and up to date is a legal duty placed on company directors rather than an optional piece of admin.
Filings with Companies House cover the full life cycle of a business: incorporation on form IN01, ongoing changes such as director appointments (AP01), director resignations (TM01), share allotments (SH01), changes to the registered office (AD01), and the yearly confirmation statement (CS01). There are also forms for more significant events, such as changing the company name (NM01), registering a charge (MR01), or striking the company off the register (DS01).
Most filings can now be made online through the Companies House service, though paper versions remain available for situations where the online route is not suitable.
How to use this document
01
Work out which form you actually need. Start by identifying exactly what has changed or what you are trying to do. Appointing a director is AP01, removing one is TM01, allotting new shares is SH01, and updating the registered office is AD01. Picking the wrong form is one of the most common reasons filings get rejected, so it is worth checking before you start.
02
Gather the information the form asks for. Each form has its own data requirements, from dates of birth and service addresses for directors, to share class descriptions and prescribed particulars for share allotments. Have the company number, authentication code, and any supporting details ready before you open the online form so you do not lose progress part way through.
03
File online where possible. The Companies House online filing service handles most routine forms and processes them far faster than paper. You will need the company's authentication code to sign in. Paper filings still have a place for certain forms and situations, but expect longer processing times and check gov.uk for the current fee.
04
Check deadlines carefully. Some filings, such as the confirmation statement and annual accounts, have fixed deadlines tied to the company's incorporation date or accounting reference date. Others, such as director changes, must be filed within a set period after the event. Missing a deadline can lead to penalties and, in serious cases, the company being struck off the register.
05
Keep copies and update internal records. Once a filing is accepted, download the confirmation or receipt and update your statutory registers, such as the register of members and the register of directors. The Companies House record and your internal records should match, and the statutory registers remain a legal requirement alongside the public filings.
Common questions
QWhat is a confirmation statement and how often do I file one?
The confirmation statement, form CS01, is an annual filing that confirms the information Companies House holds about your company is still accurate. It covers details such as directors, registered office, shareholders, and people with significant control. Every active company must file at least one confirmation statement each year, even if nothing has changed. Check gov.uk for the current filing fee.
QHow do I appoint a new director?
A new director is appointed using form AP01 for an individual or AP02 for a corporate director. You will need their full name, date of birth, nationality, occupation, service address, and usual residential address. The filing should be made within 14 days of the appointment taking effect, and your internal register of directors should be updated at the same time.
QWhat form do I use to issue new shares?
Allotments of new shares are reported to Companies House on form SH01, the return of allotment of shares. You will need the number and class of shares allotted, the amount paid or unpaid on each, and the prescribed particulars of the share class. The form should be filed within one month of the allotment, and the company's register of members must be updated.
QHow do I change my registered office address?
A change of registered office is filed on form AD01. The new address must be in the same country of registration as the company, so an England and Wales company cannot move its registered office to Scotland without a more involved process. The change takes effect once it is registered by Companies House, not on the date you submit the form.
QWhat happens if I file a form late?
Late filing of accounts attracts an automatic civil penalty that increases the longer the delay continues. Other late filings may not trigger an immediate fine, but they can lead to the register being inaccurate, which is itself a breach of duty by the directors. Persistent failure to file can result in the company being struck off the register.
QCan I correct a mistake on a form I have already filed?
Yes, in most cases. Some forms have a dedicated correction route, such as RP04 for second filings where the original contained errors. For others, you may need to file an updated version of the original form. It is worth checking the position before filing anything new, because the wrong correction route can make the public record more confusing, not less.
QDo I need to file anything when I close a company?
A solvent company that is no longer needed can apply to be struck off the register using form DS01. Certain conditions must be met, including that the company has not traded or changed name in the previous three months. Insolvent companies follow a different route involving a formal liquidation process rather than a simple strike-off application.
