Companies Act 2006 Statutory Records and Filing Obligations

Companies Act in Brief

Companies Act 2006 sets the statutory framework - director duties, statutory registers, annual confirmation statement, accounting records and filings at Companies House. Economic Crime Act changes add verification for directors and PSCs.

The Companies Act 2006 Framework

The Companies Act 2006 is the UK's principal company law statute. It sets out the legal framework for forming, running, maintaining and dissolving UK companies. The Act applies to every UK-incorporated company, from a single-member private limited company through to large public listed groups.

The core obligations under the Act fall into four main areas:

Statutory registers - the records the company must maintain about its members, directors, secretaries, charges and people with significant control
Filings at Companies House - the annual confirmation statement, accounts, and event-driven filings such as changes of director or registered office
Director duties - the seven general duties owed by every director to the company under sections 171 to 177
Operational requirements - the registered office, company name display, document signing, and similar day-to-day obligations

For SMEs, most of these duties apply in the same way they apply to large companies. The main scaling is in the accounts filing regime, where small and micro companies have access to simplified filing options. There is also the audit exemption, which is generally available to small companies that meet specific criteria.

Statutory Registers

Every UK company must maintain a set of statutory registers recording specific information about the company and the people involved in it. The principal registers are:

Register of members - the shareholders of the company. This is the legal record of share ownership and is the document the courts will look at to determine who the members are
Register of directors - the current and historical directors of the company, with their service addresses and key personal information
Register of directors' residential addresses - kept separately because residential addresses are protected information not generally available to the public
Register of secretaries - where the company has a company secretary (no longer mandatory for private companies)
Register of charges - records of any mortgages, fixed charges or floating charges granted over the company's assets
Register of people with significant control (PSC) - the individuals with significant control or influence over the company. Information about PSCs is also filed at Companies House

The registers can be kept electronically or on paper, and most must be available for inspection by members and (in some cases) the public. Failure to maintain the registers properly is an offence on the part of the company and every officer in default. Many small private companies elect to keep their statutory information at Companies House under section 128B rather than maintaining separate internal registers - this can simplify administration but means the information is publicly visible.

Companies House Filings

Every UK company has annual filing obligations at Companies House and must update specific information when key events happen. The principal filings are:

Confirmation statement - filed at least once every 12 months, confirming that the information held at Companies House is up to date. This replaced the annual return in 2016
Annual accounts - filed within set deadlines after the financial year end. Small and micro companies have access to simplified filing options, though these are being narrowed under recent reforms
Event-driven filings - changes of director, secretary, registered office, share capital, articles of association, and similar matters need to be filed promptly when they occur
Person with significant control updates - any change in PSC information needs to be filed within 14 days of the change being recorded internally

Failure to file on time results in late filing penalties (for accounts) and can ultimately lead to the company being struck off the register. Persistent failure to comply with filing duties can also result in director disqualification under the Company Directors Disqualification Act 1986.

Director Duties under Sections 171-177

The Companies Act 2006 codified the core duties of directors at sections 171 to 177. These apply to every director of every UK company, regardless of size or whether the role is full-time, part-time, executive or non-executive:

Duty to act within powers (s.171) - act in accordance with the company's constitution and only exercise powers for the purposes for which they are conferred
Duty to promote the success of the company (s.172) - act in the way the director considers, in good faith, would be most likely to promote the success of the company for the benefit of its members as a whole, having regard to factors including long-term consequences, employees, supplier and customer relationships, community and environmental impact, and the company's reputation
Duty to exercise independent judgment (s.173) - form their own judgment rather than simply following the lead of others
Duty to exercise reasonable care, skill and diligence (s.174) - the standard expected of a reasonably diligent person with the general knowledge, skill and experience that may reasonably be expected of someone in the role, plus any specific knowledge or experience the director actually has
Duty to avoid conflicts of interest (s.175) - avoid situations where the director's interests conflict, or might conflict, with those of the company
Duty not to accept benefits from third parties (s.176) - not accept benefits from third parties that arise from being a director
Duty to declare interest in proposed transactions (s.177) - declare any direct or indirect interest in a proposed transaction or arrangement with the company

Breach of these duties can result in the director being personally liable to the company for any loss caused, having to account for any profit made, or having the transaction set aside. The duties are enforceable by the company itself or, in some cases, by shareholders through a derivative action.

For SME directors, the duties under sections 171 to 177 are often overlooked because the day-to-day reality of running a small business does not feel like a board environment. But the duties apply identically. The director of a one-person limited company is subject to the same duty to act within the company's powers, exercise independent judgment, avoid conflicts of interest and declare interests in transactions as the director of a FTSE 100 company. The practical answer for most SMEs is plain enough: a board minute when significant decisions are made, a register of directors' interests that is reviewed periodically, and a habit of separating personal and company affairs cleanly. The discipline pays off if a question ever arises - either from HMRC, from a creditor, or from a co-shareholder.

Companies House Reform - The ECCT Act 2023

The Economic Crime and Corporate Transparency Act 2023 introduced the most significant changes to UK company law since the 2006 Act. The reforms are being phased in over several years through Companies House, with key elements including:

Identity verification - directors and people with significant control are required to verify their identity, either directly with Companies House or through an Authorised Corporate Service Provider (ACSP). The verification is being phased in for new and existing companies
Enhanced Companies House powers - to query, reject and remove information that does not appear to be accurate, and to require evidence to support filings
Restrictions on registered office addresses - the registered office must be at an appropriate address where a delivery to the company would be expected to come to the attention of someone acting for it. PO Box addresses are no longer acceptable
Restrictions on company names - new powers to refuse and direct changes of names that are misleading or that suggest a connection to public authorities
Software-only filing of accounts - paper and web-based filing of accounts is being phased out in favour of mandatory software filing for all companies
Changes to small and micro company accounts - the option to file abridged or filleted accounts is being narrowed, with a move toward more transparency in published accounts

The detailed timetable for these changes is set by Companies House and updated periodically. Directors and company secretaries should monitor the Companies House Reform updates at gov.uk to stay current with the implementation schedule for their specific company circumstances.

Operational Requirements

The Companies Act 2006 imposes a set of day-to-day operational requirements that apply to every UK company:

Registered office - every company must have a registered office in the part of the UK where it is registered. Following the ECCT Act 2023 reforms, this must be an appropriate address where official correspondence can be received
Display of company name and number - the company name must be displayed at the registered office and any other location where business is carried on. The company name, number, registered office address, and place of registration must appear on letterheads, websites, order forms and similar business communications
Document signing - documents executed by the company must be signed in accordance with the Act, typically by two directors, by a director and the secretary, or by a single director witnessed by another person
Accounting records - the company must keep accounting records sufficient to show and explain its transactions, disclose its financial position with reasonable accuracy at any time, and enable the directors to satisfy themselves that any accounts comply with the Act

What I look for on Companies Act compliance in audits is the link between what is filed at Companies House and what the company actually does. Are the directors at Companies House the same as the people making decisions? Is the registered office the actual address used for company business? Are the PSC entries up to date? Have all the event-driven filings been made within the deadlines, or is there a backlog of changes that have happened internally but never made it to the public record? Companies House reform under the ECCT Act 2023 has shifted the regulator's posture from passively accepting filings to actively challenging them, which means inconsistencies that used to go unnoticed are now more likely to be queried.

The other area I focus on is the supporting evidence behind director decisions. A board minute that records the decision and the reasons for it, where directors with conflicts have declared their interest and (where appropriate) abstained from the vote, gives the company the documentary basis to demonstrate compliance with the section 171 to 177 duties. Without that record, an SME relies on memory and reconstruction if a question arises later - never a strong starting position.

The thing that catches small companies out most often on Companies House is the gap between what is supposed to be done and what actually gets done in practice. The director who got married last year and changed their name on everything except the Companies House record. The PSC who sold their shares two years ago but is still listed. The registered office that was changed but the change was never filed. None of these are dramatic, but each is a filing default. Under the post-2023 regime, Companies House is more likely to spot the gap and ask about it. The best defence is the boring one: an annual review of what is on the public record against what is actually true, and prompt filings whenever something changes.

Practical Advice

For most SMEs, Companies Act compliance comes down to keeping the statutory registers up to date, filing the confirmation statement and accounts on time, recording board decisions in a way that supports the section 171 to 177 director duties, and updating Companies House promptly when anything changes. The toolkit and registers below provide the documented basis.

The Companies House reforms under the ECCT Act 2023 are being phased in, so directors should monitor the gov.uk reform updates for the specific changes affecting their company, particularly identity verification deadlines and any narrowing of small company accounts filing options.

Frequently Asked Questions

Do small private companies have to maintain statutory registers?

Yes. The Companies Act 2006 requires every UK company to maintain statutory registers regardless of size. The registers can be kept electronically or on paper, at the registered office or another location notified to Companies House. Small private companies have the option under section 128B to elect to keep their statutory information at Companies House rather than maintain separate internal registers - this can simplify administration but means the information is publicly visible. Failure to maintain the registers properly is a criminal offence on the part of the company and every officer in default.

What are the consequences of late filing?

Late filing of accounts results in automatic civil penalties that increase the longer the delay continues, with higher penalties for public companies than for private companies. Late filing of the confirmation statement does not attract an automatic penalty but can result in the company being marked as overdue and ultimately struck off the register. Persistent failure to file can lead to director disqualification under the Company Directors Disqualification Act 1986. The current penalty levels and filing deadlines are published by Companies House and should be checked at gov.uk for the latest position.

What is identity verification at Companies House?

Identity verification was introduced by the Economic Crime and Corporate Transparency Act 2023 and is being phased in for directors and people with significant control. Each individual must verify their identity directly with Companies House (using a digital service) or through an Authorised Corporate Service Provider (ACSP) such as an accountant or company formation agent. Once verified, the individual receives a personal identification code that is used in subsequent filings. The detailed timetable for new and existing companies is set by Companies House and being rolled out in stages. Failure to verify when required can prevent the individual from acting in the role.

Can I be personally liable as a director of a limited company?

Yes, in specific circumstances. While the limited company structure generally protects shareholders from the company's debts, directors can face personal liability where they have breached their statutory duties under sections 171 to 177 of the Companies Act 2006, where they have caused the company to trade wrongfully or fraudulently while insolvent, where they have given personal guarantees, or where personal liability arises under specific statutes (for example health and safety, environmental, tax or employment legislation). Director duties are owed to the company and can be enforced by it; the protection of limited liability does not insulate a director from breach of those duties.

Do I need a company secretary?

Not for a private company. The Companies Act 2006 made the company secretary optional for private companies, while remaining mandatory for public companies. A private company can choose to appoint a secretary if it wishes, in which case the appointment must be filed at Companies House and the relevant register maintained. For most SMEs, the practical answer is that the company secretary role is absorbed by a director or by the company's accountant or company formation agent. Whether or not a formal secretary is appointed, the underlying duties to maintain registers and file documents on time still apply.
