Many founders reach a point where they need senior, experienced input but are not ready, or not willing, to reshape their statutory board. Perhaps the company is too small to justify independent non-executive directors, the shareholders want to keep control of the board simple, or the business needs specialist knowledge in a particular market or technology. An advisory board can fill that gap.
Done well, an advisory board gives a growing company access to expertise, networks and challenge at a fraction of the cost and formality of a full board. Done badly, it becomes an occasional dinner with well-meaning contacts that produces little, or, worse, blurs the legal line between advising and directing. This guide explains how to build an advisory board that is clearly structured, properly documented and genuinely useful.
Key takeaways
- An advisory board has no legal authority; advisors are not directors and do not owe directors’ fiduciary duties to the company.
- Advisors must not direct the company in practice, or they risk being treated as shadow directors under the Companies Act 2006.
- Start with a clear purpose, then recruit for specific skills, networks and perspectives the business lacks.
- Written terms of reference and advisor agreements set expectations on role, time, confidentiality and conflicts.
- Compensation can include fees or equity, but share schemes such as EMI may not be available to non-employees, so take advice.
- Measure value against the objectives you set and refresh membership as the business evolves.
Advisory board versus statutory board
The statutory board of directors is the legally appointed body that manages the company. Directors are registered at Companies House, owe statutory duties under the Companies Act 2006 and are collectively responsible for the company’s decisions. An advisory board, by contrast, is an informal group set up by the company to provide advice. It has no decision-making power, and the statutory board is free to accept or reject its recommendations.
| Feature | Statutory board | Advisory board |
|---|---|---|
| Legal status | Required by company law; directors registered at Companies House | Voluntary; no formal legal status |
| Authority | Makes binding decisions on behalf of the company | Provides advice only; no decision-making power |
| Duties | Statutory directors’ duties, including those in sections 171 to 177 | Contractual obligations only, such as confidentiality, set out in an advisor agreement |
| Liability | Personal liability in certain circumstances, such as wrongful trading | Generally limited, unless the advisor acts as a shadow or de facto director |
| Composition | Executive and non-executive directors, often including investor representatives | Industry experts, specialists, potential customers or partners |
| Formality | Formal meetings, minutes, resolutions and filings | Flexible format, agreed in terms of reference |
| Typical cost | Higher, reflecting responsibility and time commitment | Usually lower; often a mix of fees and equity |
| Best for | Governance, accountability and investor oversight | Expertise, networks and strategic sounding board |
The two are not alternatives in every case. Many companies have both: a small statutory board for governance and an advisory board for specialist input. As a business matures or takes on institutional investment, it often makes sense to appoint independent non-executive directors to the statutory board as well.
Understanding shadow director risk
Advisors are not directors and do not owe directors’ fiduciary duties. But that protection depends on how they behave, not just on their job title.
Under section 251 of the Companies Act 2006, a shadow director is a person in accordance with whose directions or instructions the directors of a company are accustomed to act. There is an exception for advice given in a professional capacity, but it will not protect someone who in reality controls the board’s decisions. Shadow directors can be subject to the general duties of directors, to the extent those duties are capable of applying, and to liabilities such as wrongful trading under insolvency law. A person who acts as a director in practice, for instance by negotiating contracts on the company’s behalf or presenting themselves as a director, may also be treated as a de facto director.
How to keep the line clear
- Make clear in all documents that the advisory board is advisory only and that decisions rest with the statutory board.
- Ensure the statutory board genuinely considers advice and makes its own decisions, recording its reasoning where significant.
- Do not give advisors authority to sign contracts, instruct staff or commit the company.
- Avoid titles that suggest directorship, and check how advisors are described on the website and on LinkedIn.
- Be particularly careful where an advisor is also a significant investor or lender, because their influence may be greater in practice.
Tip: Use language such as “the advisory board recommends” rather than “the advisory board decided” in notes and papers. Small wording choices help reinforce that the statutory board remains in control.
When an advisory board makes sense
An advisory board is particularly useful when a company:
- is entering a new market, sector or country and needs specialist knowledge;
- is developing a technology or product where expert input materially reduces risk;
- needs introductions to customers, partners, investors or talent;
- wants to build credibility ahead of fundraising, as part of wider investor readiness;
- is not yet ready for independent directors but wants structured external challenge.
It is less suitable as a substitute for good governance where the business already needs accountability, for example where outside investors require board representation, or where the company faces significant financial or regulatory risk.
Designing your advisory board
Start with purpose
Define what you want the advisory board to achieve over the next one to two years. For example, a 30-person health-tech business might want help with NHS procurement, clinical credibility and preparing for a Series A round. Those objectives determine who you need.
Size and composition
Three to five advisors is a practical size for most SMEs. It provides diverse views while keeping meetings manageable. Think about the mix of:
- Sector expertise: people who know your market, customers and competitors.
- Functional expertise: specialists in areas such as technology, regulation, finance or international expansion.
- Networks: advisors who can open doors to customers, partners or investors.
- Diversity of thought: different backgrounds, experiences and perspectives reduce groupthink.
Chair
Appoint a chair of the advisory board, who may be one of the advisors or the founder. The chair keeps discussions focused on the agreed objectives and ensures advice is captured and followed up.
Recruiting advisors
The strongest advisory boards are recruited deliberately rather than assembled from friends and former colleagues. Write a brief role profile for each seat, covering the expertise sought, the expected time commitment and what the advisor will receive in return.
- Search widely: use your network, investors, industry bodies and specialist search support.
- Test for fit: hold more than one conversation, ideally including a working session on a real business challenge.
- Check references: speak to other founders or boards they have advised.
- Probe commitment: ask how many other advisory and board roles they hold and how much time they can realistically offer.
- Identify conflicts: clarify relationships with competitors, suppliers or investors at the outset.

Terms of reference and advisor agreements
Two documents provide structure: terms of reference for the advisory board as a whole, and an individual agreement with each advisor.
Terms of reference
- purpose and objectives;
- the advisory, non-binding nature of the board’s role;
- membership, chair and term of appointment;
- meeting frequency and format;
- how advice is reported to the statutory board;
- how performance will be reviewed.
Individual advisor agreements
- expected time commitment and activities;
- compensation and expenses;
- confidentiality obligations;
- ownership of intellectual property created in the course of the role;
- conflicts of interest and how they will be declared;
- data protection responsibilities where advisors handle personal data;
- term, notice and termination, including what happens to unvested equity.
Take legal advice on the agreement, particularly on IP, equity and employment status. An advisor engagement should be structured so that the advisor is not inadvertently treated as an employee or a director.

Meeting cadence and running effective sessions
Most advisory boards meet quarterly, with the option of ad hoc conversations between meetings. Some companies hold a longer annual strategy session. The right cadence depends on your objectives and how quickly the business is moving.
Effective sessions share some common features:
- Focused agendas: two or three substantive questions on which you genuinely need input, rather than a long operational update.
- Pre-reading: a concise pack circulated in advance, so time together is spent on discussion.
- Clear questions: frame issues as decisions you are weighing, such as “Should we enter Germany or the Netherlands first?”
- Recorded actions: capture advice and follow-ups, and report back on what you did with it at the next meeting.
Many of the principles of running an effective board meeting apply equally to advisory sessions, even though the legal formalities do not.
Working with advisors between meetings
Much of an advisory board’s value is created outside formal sessions. An advisor might review a pricing proposal, join a call with a prospective partner or sense-check a hiring decision. Agree in advance how these requests will work: who in the business can contact advisors, roughly how much time is included in their arrangement, and how additional work will be scoped and paid for. Keep a simple log of requests and outcomes, which also feeds the annual review of value. Be mindful, too, that the more closely an advisor is involved in operational matters, the more important it is that decisions remain visibly with management and the statutory board.
Keeping the statutory board informed
Report the advisory board’s main recommendations to the statutory board, together with management’s response. This creates a clear record that advice was considered and decisions were made by the directors.
Compensation options
There is no single market rate for advisors, and arrangements vary with the company’s stage, the advisor’s seniority and the time required. Common approaches include:
- Fees: a fixed fee per meeting, a monthly retainer or a day rate for additional work. Fees give clarity and suit established businesses with cash flow.
- Equity or options: early-stage companies often offer a small equity stake or share options that vest over the advisor’s term, aligning interests with long-term success.
- A combination: a modest fee plus equity can balance cash constraints with fair reward.
- Expenses only: some advisors, particularly those motivated by learning or relationships, may accept expenses alone, though this can make commitment harder to sustain.
Be careful with equity. Tax-advantaged schemes such as Enterprise Management Incentives (EMI) are generally designed for employees who meet working-time requirements, so they may be unavailable to non-employee advisors. Alternatives exist, but the tax and legal implications vary, and you should seek advice from a qualified tax adviser or lawyer before offering equity to advisors.
Tip: Whatever you offer, link it to an agreed time commitment and a defined term, with vesting or review points. This keeps expectations clear on both sides and makes it easier to refresh the board later.
Measuring value and refreshing the board
An advisory board should earn its place. At least once a year, review its contribution against the objectives set out in the terms of reference. Useful questions include:
- Did the advice materially influence any significant decisions?
- Did advisors make introductions that led to customers, partners, hires or investment?
- Did they help the business avoid mistakes or reduce risk?
- Was attendance and preparation consistent?
- Are the skills on the advisory board still the ones the business needs?
Set fixed terms, typically one or two years, renewable by mutual agreement. This makes it easier to thank advisors whose expertise is no longer central and bring in new perspectives as the company evolves. As the business grows, some advisors may be natural candidates for a non-executive role on the statutory board, subject to a proper appointment process.
Frequently asked questions
Do advisory board members have legal duties?
Advisors are not directors and do not owe the statutory duties that apply to directors. Their obligations usually come from their advisor agreement, such as confidentiality. However, if an advisor directs the company in practice, they risk being treated as a shadow or de facto director.
What is a shadow director?
Under section 251 of the Companies Act 2006, a shadow director is someone in accordance with whose directions or instructions the company’s directors are accustomed to act. Advice given in a professional capacity is excluded, but shadow directors can be subject to directors’ duties and liabilities.
How many members should an advisory board have?
For most SMEs, three to five advisors works well. This gives a range of expertise while keeping meetings focused and manageable.
Can advisors receive EMI options?
EMI is generally aimed at employees who meet specific working-time conditions, so non-employee advisors are often not eligible. Other equity arrangements may be possible, but you should seek professional tax and legal advice before making any offer.
How often should an advisory board meet?
Quarterly meetings are common, supplemented by ad hoc calls when specific issues arise. The cadence should reflect your objectives and pace of growth.
