Director duties and personal liability in a UK limited company: what every founder must know

The Insolvency Service disqualifies over a thousand directors each year. Some know the rules and break them anyway. Many simply had no idea the rules existed until an investigation began.

Becoming a director of a UK limited company gives you a legal title, a line on the Companies House register, and — if things go well — a share in something you've built. What it also gives you is a set of seven statutory duties codified in the Companies Act 2006, a filing calendar that does not forgive missed deadlines, and personal exposure that the word "limited" in your company name does not always cover.

This guide sets out every duty, every liability risk, and the practical steps that keep UK founders on the right side of the law — whether you are a sole founder-director or sitting on a three-person board.

The seven statutory duties every UK director owes

Sections 171 to 177 of the Companies Act 2006 set out seven general duties that every director owes to the company. Not to the shareholders personally, not to employees, not to creditors (although that shifts when the company approaches insolvency) — to the company itself as a separate legal person. These duties apply from the moment of appointment and run until you formally resign or are removed.

1. Duty to act within powers (s. 171)

A director must act in accordance with the company's constitution — primarily the Articles of Association — and only exercise powers for the purposes for which they were conferred. If the Articles say a particular decision needs shareholder approval, you cannot bypass that through a board resolution. If the company's objects restrict it to a specific trade, you cannot pivot the business into a different sector without first amending the Articles by special resolution.

2. Duty to promote the success of the company (s. 172)

This is the broadest and most litigated duty. A director must act in the way they consider, in good faith, would be most likely to promote the success of the company for the benefit of its members as a whole. When making that judgement, the Act requires you to have regard to:

• The likely consequences of any decision in the long term
• The interests of the company's employees
• The need to foster the company's business relationships with suppliers, customers, and others
• The impact of the company's operations on the community and the environment
• The desirability of the company maintaining a reputation for high standards of business conduct
• The need to act fairly between the members of the company

In practice, this means you should document major decisions — why you chose a particular supplier, why you rejected a tender, why you invested cash reserves in a new product line. If a decision is later challenged, the court looks at whether a reasonable director, properly informed, could have reached the same conclusion. A paper trail protects you.

3. Duty to exercise independent judgement (s. 173)

You must not simply rubber-stamp whatever the majority shareholder, a co-founder, or an investor tells you to do. Each director is expected to form their own view. This does not prevent you from relying on professional advice (legal, financial, technical), but the final decision remains yours. Nominee directors — common in investor-backed startups — often trip over this duty by acting solely on the nominating shareholder's instructions.

4. Duty to exercise reasonable care, skill, and diligence (s. 174)

The standard here is dual: what a reasonably diligent person with the general knowledge, skill, and experience expected of someone in that role would do, and what you personally would be expected to do given any additional expertise you bring. A director with an accounting qualification is held to a higher standard on financial matters than a director without one. Ignorance of the company's financial position is not a defence — it is evidence of a breach.

5. Duty to avoid conflicts of interest (s. 175)

A director must avoid any situation in which they have, or could have, a direct or indirect interest that conflicts with the interests of the company. This covers personal business opportunities, side projects in the same market, and interests in competitor companies. The duty is strict: even if you believe the conflict would never actually cause harm, you must either avoid it or have it authorised by the other directors (if the Articles permit) or by the shareholders.

6. Duty not to accept benefits from third parties (s. 176)

You must not accept any benefit from a third party that is conferred by reason of your being a director, or by reason of doing (or not doing) anything as a director. This catches bribes, obviously, but also subtler situations — a supplier offering you personal hospitality to secure a contract, or a landlord offering favourable terms on your personal property to keep the company's lease in place.

7. Duty to declare interest in proposed transactions (s. 177)

If you are in any way interested in a proposed transaction or arrangement with the company, you must declare the nature and extent of that interest to the other directors before the company enters into the transaction. For example, if the company is about to lease premises owned by your spouse, you must declare that interest. Failure to do so can make the transaction voidable and exposes you to personal liability for any profit made.

Personal liability: when "limited" does not protect you

The entire point of a limited company is that the shareholders' liability is limited to the amount unpaid on their shares — typically nothing if shares are fully paid. But that protection does not extend to directors who breach their duties, trade while insolvent, or allow the company to be used for fraud. Here are the main routes through which personal liability bites.

Wrongful trading (s. 214 Insolvency Act 1986)

If you knew, or ought to have concluded, that there was no reasonable prospect of the company avoiding insolvent liquidation, and you allowed the company to continue trading, the court can order you to contribute personally to the company's assets. The standard is what a reasonably diligent person in your position would have known — not what you actually knew. A lack of awareness of the company's financial position is not a defence.

The practical trigger is usually a director continuing to take on new debt, placing orders with suppliers, or accepting customer deposits after the point at which the company was clearly unable to pay its debts as they fell due. To defend against a wrongful trading claim, you need to show that from the moment you ought to have known, you took every step to minimise loss to creditors — typically seeking professional insolvency advice and ceasing to trade if advised to do so.

Fraudulent trading (s. 213 Insolvency Act 1986)

This is the more serious cousin of wrongful trading. If the company's business was carried on with intent to defraud creditors or for any fraudulent purpose, any person who was knowingly party to that fraud can be made personally liable without limit. This requires proof of dishonesty, not just poor judgement. Criminal prosecution under s. 993 of the Companies Act 2006 can also apply alongside the civil liability.

Director disqualification

The Company Directors Disqualification Act 1986 gives courts the power to disqualify a person from acting as a director for between 2 and 15 years. The Insolvency Service investigates directors of companies that enter insolvent liquidation, and can also investigate based on complaints, intelligence, or referrals from regulators. Common grounds include persistent breaches of companies legislation (late filings, missing accounts), unfit conduct, and transactions defrauding creditors.

During a disqualification period, a person cannot be a director of any company, act as a receiver or manager, or directly or indirectly be involved in the promotion, formation, or management of a company — unless with leave of the court. Breach of a disqualification order is a criminal offence.

Personal guarantees and HMRC liabilities

Many founders sign personal guarantees for bank loans, commercial leases, or credit facilities without fully appreciating that these survive the company's insolvency. A personal guarantee is a contract between you and the lender — it has nothing to do with the company's limited liability status. Similarly, HMRC can issue personal liability notices to directors for unpaid PAYE, National Insurance contributions, and VAT in certain circumstances, particularly where there is evidence of neglect or deliberate non-compliance.

Filing obligations every director must meet

Beyond the general duties, directors are personally responsible for ensuring the company meets its statutory filing deadlines. Persistent failure to file is one of the factors the Insolvency Service considers when assessing whether a director's conduct makes them unfit to hold office.

Confirmation statement

Due every 12 months from incorporation (or from the last confirmation statement), with a 14-day filing window after the review period ends. The online fee is £50; paper filing costs £110. It must be filed even if nothing has changed — the statement itself confirms that the information on the register is accurate. Missing it does not trigger an automatic fine, but Companies House can initiate strike-off proceedings, and administrative restoration after a strike-off costs at least £341 in Companies House fees (plus any overdue penalties and filings) and takes weeks. Read our confirmation statement deadline guide for a full walkthrough.

Annual accounts

The first set of accounts is due 21 months from the date of incorporation. Subsequent accounts are due 9 months after the accounting reference date. Late filing penalties start at £150 and escalate to £1,500 for private companies. These penalties are levied on the company, but the director is the person responsible for ensuring the accounts are prepared and filed — and a pattern of late filings feeds directly into any future disqualification assessment. See our annual accounts deadline guide for the full penalty schedule.

Corporation Tax return (CT600)

The CT600 is due 12 months after the end of the accounting period. Corporation Tax payment itself is due 9 months and 1 day after the end of the accounting period. Registration for Corporation Tax is required within 3 months of starting business activity — not 3 months from incorporation. "Business activity" includes invoicing, signing contracts, advertising, renting property, employing staff, or earning interest on company funds. Our Corporation Tax registration guide walks through the process.

Statutory registers

Every UK limited company is required to maintain internal statutory registers under the Companies Act 2006: the register of members (shareholders), register of directors, register of directors' residential addresses (private, not publicly available), the PSC register (people with significant control), and register of charges. Accounting records must be retained for at least 6 years from the end of the accounting period. The public Companies House record is not the legal record — the company's own statutory registers are. For a comprehensive breakdown, see our statutory registers guide.

Identity verification: the obligation that catches directors out

Since 18 November 2025, Companies House identity verification requirements have been in force for directors and PSCs under the Economic Crime and Corporate Transparency Act 2023 (ECCTA). Director verification and PSC verification are separate obligations triggered by different filings, though a person who is both a director and a PSC only needs to verify once. Under the current rules, verification is intended to be a one-off process — the same Unique Personal Code (UPC) covers any future appointment at any company — though Companies House retains the power to require re-verification.

There are two routes:

• GOV.UK One Login — free, requires valid photo ID and a smartphone
• An Authorised Corporate Service Provider (ACSP) — ACSPs can include accountancy firms, law firms, and other regulated service providers. Filing HQ is a registered ACSP, suitable if you hold a non-UK passport, cannot use the GOV.UK app, or prefer to have it handled professionally

If you were already a director before 18 November 2025 and have not yet verified, you should do so before your next confirmation statement is due — Companies House is progressively enforcing the requirement, and unverified directors may face restrictions on filing. For new directors appointed after that date, a personal code (UPC) is required for Companies House to accept the AP01 appointment form. For a full breakdown, see our guide to PSC and director verification requirements.

Common mistakes that expose directors to personal risk

These are the patterns we see repeatedly at Filing HQ — situations where a director's personal exposure could have been avoided with straightforward compliance.

1. Treating the company's money as personal funds. Drawing money from the company without proper documentation — no dividend vouchers, no board minutes, no loan agreement — creates a director's loan account that HMRC scrutinises aggressively. If the company becomes insolvent, liquidators will pursue the director personally for repayment.
2. Ignoring the point of no return on insolvency. The most common route to personal liability is continuing to trade after the point at which a reasonable director would have concluded the company could not avoid insolvent liquidation. The moment cash flow or balance sheet insolvency becomes apparent, take professional advice that day.
3. Missing filing deadlines persistently. Late accounts, overdue confirmation statements, and unfiled changes are individually small infractions. Collectively, they form a pattern that the Insolvency Service uses as primary evidence in disqualification proceedings. A director disqualified for 5 years loses the ability to run any company — not just the one that failed.
4. Failing to declare conflicts of interest. A director who awards a contract to a company they own, or sells a personal asset to the company at above market value, without declaring the interest to the board faces both personal liability for any loss caused and potential disqualification.
5. Not maintaining statutory registers. Many founders assume the Companies House register is the legal record. It is not. The company's own statutory registers are the authoritative source, and failure to maintain them is a criminal offence under s. 167 of the Companies Act 2006.
6. Signing personal guarantees without understanding the scope. A personal guarantee for a lease, a loan, or a credit facility is a contract between you and the lender. If the company fails, the guarantee survives. Read every guarantee before signing, understand the cap (if any), and negotiate wherever possible.

How to protect yourself as a director

Personal liability risk is manageable. The directors who end up in front of a court or the Insolvency Service are overwhelmingly those who ignored the basics. Here is the practical checklist:

• Know your duties. Read sections 171–177 of the Companies Act 2006 at least once. They are short, written in plain English, and freely available on legislation.gov.uk.
• Document decisions. Board minutes do not need to be formal — a clear record of the decision, the reasoning, and who agreed is sufficient. If a decision is later challenged, your minutes are your best defence.
• Monitor the company's financial position. You do not need to be an accountant, but you must know whether the company can pay its debts as they fall due. A monthly cash flow review is the minimum. If the answer is "probably not," seek advice immediately.
• File everything on time. Confirmation statements, annual accounts, PSC notifications, director changes — each one has a statutory deadline. Use a compliance service or calendar system that sends reminders well before the due date. Filing HQ's compliance packages include deadline tracking and filing for this reason.
• Declare interests early. If you have any personal interest in a transaction the company is considering, declare it to the board before the transaction is entered into. Not after, not during — before.
• Get professional advice when it matters. Insolvency, major contracts, restructuring, and anything involving HMRC investigations are situations where the cost of professional advice is a fraction of the cost of getting it wrong.
• Consider directors' and officers' (D&O) insurance. D&O insurance covers the legal costs of defending claims against you as a director. It does not cover fraud or criminal conduct, but it provides meaningful protection against negligence claims, regulatory investigations, and wrongful trading allegations.

Frequently asked questions

Can I be held personally liable even though the company is "limited"?

Yes. Limited liability protects shareholders from losses beyond their investment in shares. Directors, however, owe personal duties to the company. If you breach those duties, trade wrongfully while the company is insolvent (s. 214 Insolvency Act 1986), or participate in fraudulent trading (s. 213), the court can order you to contribute personally — potentially without any cap.

Do director duties apply to a sole founder-director?

Absolutely. All seven statutory duties under ss. 171–177 of the Companies Act 2006 apply regardless of how many directors the company has. A sole director must still act within powers, promote the success of the company, avoid conflicts, and declare interests in transactions — even if there is no one else on the board to declare to. In practice, clear documentation is even more important for sole directors because there is no one else to corroborate decisions.

What happens if I resign — do my duties end immediately?

Most duties cease on resignation, but some obligations can survive. The duty to avoid conflicts of interest (s. 175) continues to apply to the exploitation of any property, information, or opportunity of which you became aware while you were a director. You also remain exposed to wrongful trading liability for the period during which you were a director, even if you resigned before the company entered liquidation.

Is there a UK residency requirement to be a director?

No. There is no UK residency requirement for directors of UK limited companies. Nationality is also irrelevant. A director can be resident anywhere in the world. The only eligibility requirements are: aged at least 16 (s. 157 CA 2006), not disqualified under the Company Directors Disqualification Act 1986, and not an undischarged bankrupt. Identity verification under ECCTA must be completed regardless of where the director lives. For more on running a UK company from abroad, see our guide to running a UK limited company from overseas.

Does my UK limited company need a company secretary?

No. Private limited companies are not required to appoint a company secretary — this requirement was removed by the Companies Act 2006. Public limited companies (PLCs) must still have one. Many private companies choose to appoint a secretary voluntarily, or use a corporate service provider such as Filing HQ, to manage compliance and filings. Read our detailed company secretary guide for more.

How can I check if someone is a disqualified director?

The Insolvency Service maintains a publicly searchable register of disqualified directors on GOV.UK. You can search by name to check whether a proposed director is currently disqualified. This is a sensible step before any director appointment, particularly when bringing on someone you have not worked with before.
