The Rival in the Room: A Board Policy for Specialist Advisers with Competing Clients

UK boards often turn to specialist advisers precisely because generic consultancies cannot match sector depth. That depth carries a structural risk: the adviser whose judgement the board values may also be advising a rival. The issue is not usually a deliberate breach of confidence. It is the quieter problem of strategic proximity — the same person, or the same team, forming views about two organisations whose next moves affect one another.

A confidentiality clause is necessary but insufficient. It governs documents and disclosures. It does not govern pattern recognition, comparator insight or the informal transfer of judgement that makes specialist advice valuable. Boards need a clearer test before appointment and a monitoring policy during the engagement.

Why confidentiality is the wrong starting point

Confidentiality clauses tend to assume that risk travels through papers. In specialist advisory work, risk also travels through people. An adviser who has seen how a rival's board thinks about pricing, capital allocation or regulatory posture cannot simply forget that context. The question is not whether the adviser is trustworthy. It is whether the engagement design makes accidental or structural leakage unlikely.

That is why a 'competitor clause' should be understood as a governance instrument, not a legal ornament. It should force the board to ask how close the adviser is to a competitor, what information the adviser will see, who will staff the work and how conflicts will be escalated.

Four questions before approval

Strategic proximity. How close is the competitor? A rival in the same bidding pool, customer segment or regulatory perimeter is different from a firm that happens to share a sector label. Boards should assess proximity by market, geography, product and timing. If the advice will shape a live commercial decision, the threshold for approval should be higher.

Information segregation. What will the adviser actually see? Boards should distinguish between public sector data, commercially sensitive performance data and forward-looking strategy. For high-proximity engagements, the board should require a documented segregation plan: named access controls, clean-team arrangements where appropriate, and a clear rule on what cannot be shared with the adviser's wider firm.

Team staffing. Chinese walls fail when the same partner or junior team works across both relationships. The board should ask for named personnel, reporting lines and a commitment that the competitor engagement will not be staffed by the same core team. This is more useful than a general assurance that the firm takes confidentiality seriously.

Conflict escalation. Who at the adviser is responsible for conflicts? What triggers notification? How quickly must the board be told? A workable clause should require notice when the adviser accepts a new mandate with a named competitor or a firm in the same strategic space, within a defined period. It should also give the board a right to reassign, pause or terminate.

A board-level approval and monitoring policy

A proportionate policy can be built in five steps.

First, classify engagements by competitor proximity: low, medium and high. Low-proximity work may need only standard confidentiality and a declaration. High-proximity work should require board or committee approval, a named executive owner and a written segregation plan.

Second, require disclosure of current and recent clients in the same sector, limited to what is necessary for the conflict assessment. The aim is not to pry into the adviser's entire client base but to test whether a rival relationship creates a material risk.

Third, put the competitor clause into the engagement letter. It should include a notification obligation for new mandates in the same strategic space, a named conflicts contact, a commitment to team separation where required, and clear reassignment or termination rights.

Fourth, monitor through a standing board item. The relationship owner should report any new competitor mandate, any change in staffing, any information-segregation incident and any deterioration in the adviser's ability to give independent challenge.

Fifth, review at exit. The board should ask whether the clause worked in practice: were notifications timely, was staffing respected, did the adviser's other work compromise the quality of challenge? That review should inform the next appointment.

The limits of the clause

No clause can eliminate the risk that sector expertise becomes competitor insight. Over-restriction has costs too: the best specialists often serve several organisations in a sector, and a board that demands exclusivity may lose access to the very judgement it needs.

The practical answer is proportionality. High-proximity, strategy-shaping work deserves tighter controls. Lower-proximity work can be governed by disclosure and standard confidentiality. What matters is that the board makes the judgement deliberately, records it and revisits it when the engagement changes.

For UK boards, the competitor clause should be less a prohibition than a discipline: a structured way to decide when shared expertise is acceptable, what safeguards are required and who is accountable when the boundary is tested.
