Many people assume director responsibility only applies if you are formally appointed and listed at Companies House.
In reality, UK law can treat someone as a director even if they were never officially appointed, simply because of the influence they hold within the business. This often catches people by surprise, particularly founders who have stepped back, investors who take an active role, senior individuals who are heavily involved in decision making, and in some cases even external consultants.
At Johnson and Boon Solicitors, we advise clients where concerns arise about board control, decision making power, and personal exposure linked to director status.
What is a shadow director? (Companies Act 2006, section 251)
The legal definition of a shadow director is found in section 251 of the Companies Act 2006.
In straightforward terms, a shadow director is a person in accordance with whose directions or instructions the directors of a company are accustomed to act.
This definition is important because it focuses on what happens in practice, not job titles, formal appointments, or whether someone appears on Companies House.
If the board consistently follows the instructions of an individual, that individual may be treated as a shadow director, even if they never intended to take on that role.
The professional adviser exception (Companies Act 2006, s251(2))
The Companies Act 2006 recognises that directors often act on professional guidance, and that doing so should not automatically make an adviser a shadow director.
The exception is set out in section 251(2) of the Companies Act 2006. It provides that a person is not to be regarded as a shadow director by reason only that the directors act on advice given by that person and the advice is given in a professional capacity.
This is an important distinction. There is a difference between professional advice which directors may rely on, and directing the board where directors are accustomed to act on someone’s instructions.
If influence shifts from advice into control, the risk of shadow director status increases.
External consultants and advisers can also fall into the trap
In practice, shadow director concerns do not only arise with investors and founders. External consultants can also become exposed, particularly where a business relies heavily on them to make key decisions.
This risk is higher where an external consultant is effectively performing a senior leadership role, such as overseeing operations, managing negotiations, directing hiring decisions, or controlling major spending. If directors become accustomed to acting on the consultant’s instructions, rather than using the consultant for support and guidance, shadow director arguments can arise.
Businesses often bring in consultants during difficult periods, such as restructuring, rapid growth, or crisis management. These are also the situations where governance tends to weaken, decision making becomes informal, and legal exposure increases.
Who is most at risk of being classed as a shadow director?
Shadow director risk commonly arises where someone has influence such as a major investor who approves key decisions behind the scenes, a founder who has stepped away formally but still directs strategy, a dominant shareholder who dictates outcomes, a senior adviser who effectively runs the business, or an external consultant taking on leadership responsibilities without formal appointment.
This often starts informally, with a person helping the business. Over time it can become a legal problem if the board is no longer exercising independent judgement.
Warning signs: how shadow directorship happens in practice
A shadow director issue may exist where someone gives instructions that are followed without proper board discussion, expects decisions to be made their way as a condition of ongoing support, controls significant company decisions without being accountable, uses directors as signatories rather than decision makers, or sits outside the board but effectively runs the company.
These situations are particularly risky when a company enters financial pressure, a shareholder dispute, or a regulatory issue, because decision making records are often examined closely later on.
Why being a shadow director matters
Being treated as a shadow director can bring serious consequences.
Shadow director arguments tend to surface when there is a dispute about who was really in control, insolvency or creditor pressure, allegations of poor governance or mismanagement, legal claims involving company decisions, or scrutiny into director conduct.
The risk is not just commercial. It can become personal.
What should you do if you are concerned?
If you suspect that someone is acting as a shadow director, or you have been accused of being one, early legal advice is essential. It is much easier to manage risk before a situation becomes adversarial.
At Johnson and Boon Solicitors, we regularly advise on whether shadow director exposure may exist under Companies Act 2006 section 251, how to strengthen board independence and governance, how to structure investor involvement safely, handling disputes involving control and responsibility, and protecting individuals from unintended personal exposure.

FAQs: Shadow Directors
Can I be a shadow director even if I am not registered at Companies House?
Yes. Shadow director status is based on influence and control in practice, not whether you are formally appointed.
Does giving advice to directors make me a shadow director?
Not automatically. Section 251(2) of the Companies Act 2006 confirms that a person is not to be treated as a shadow director by reason only that the directors act on their advice, provided that advice is given in a professional capacity.
Can investors become shadow directors?
They can. If an investor goes beyond oversight and begins directing company decisions in a way the board is accustomed to follow, shadow director risk increases.
Can external consultants become shadow directors?
Yes. This can happen where a consultant moves beyond the scope defined in their letter of engagement and starts directing key business decisions, particularly if the board becomes accustomed to acting on their instructions.
Can a founder who has stepped back still be classed as a shadow director?
Yes. This commonly happens where a founder remains involved in decision making and the board continues to act on their instructions.
What is the difference between a shadow director and a de facto director?
A de facto director is someone who acts as a director in practice, often taking on director style responsibilities openly. A shadow director tends to operate behind the scenes by influencing the board’s decisions without being formally appointed.
Why does shadow director status matter?
It matters because it can lead to personal legal exposure if the company becomes involved in disputes, regulatory issues, or insolvency processes, particularly where decision making is challenged.
What should I do if I am accused of being a shadow director?
Take legal advice quickly. These situations can escalate, and early advice can help you protect your position and clarify responsibilities.
