Senior Reference Checking — A Practical Guide

Senior Reference Checking: A Practical Guide

Reference checking is consistently the most underinvested stage of the senior executive appointment process and the one that most reliably surfaces material information when conducted rigorously. Most organisations conduct references as a formality — confirming employment dates with HR departments, or brief conversations with referees selected and briefed by the candidate. These produce no meaningful assessment information, and their function is accountability rather than genuine insight.

Rigorous senior reference checking — structured conversations with principal references who have directly managed or been closely managed by the candidate, asking specific questions about performance in roles most relevant to the appointment being made — consistently produces material information unavailable from the assessment process. This information is sometimes confirmatory (the reference validates the candidate’s self-assessment and assessment performance), sometimes additive (the reference provides specific performance context that was not volunteered), and occasionally disconfirmatory — revealing a performance concern or behavioural pattern that the structured assessment did not surface.

This guide explains how to design and conduct senior reference checks, the difference between principal references and character references, the FCA regulatory reference requirement, and the specific reference considerations for board-level appointments. It is designed for both hiring organisations and search firms managing the reference process on their behalf.

Principal References vs Character References

The most important distinction in senior reference checking is between principal references — people who have directly managed the candidate or been directly managed by them and who have specific, evidenced, first-hand knowledge of their performance — and character references — people who know the candidate personally or professionally but cannot provide direct performance evidence.

Principal references are: the candidate’s most recent direct manager (who has the most current and specific performance information); their manager’s manager if accessible (who provides context on how the candidate was perceived at the level above their direct management relationship); and a direct report who managed a significant function (who can provide evidence of how the candidate leads, develops, and holds accountable their own team). These are the references that produce the most diagnostically valuable information and that should be prioritised in senior reference processes.

Character references — professional colleagues, board members who sat alongside the candidate but did not manage them, and professional acquaintances — add social proof but limited performance information. A character reference from a respected figure who “has known [candidate] for fifteen years and can vouch for their integrity” tells the hiring organisation almost nothing about how the candidate will perform in the specific role being offered. Character references are appropriate as supplementary references after principal references have been obtained, not as substitutes for them.

The most common reference design failure at senior level is accepting the candidate’s list of three or four referees without question when that list consists entirely of people the candidate is confident will be positive. Best practice requires: a minimum of two principal references (one manager, one direct report); at least one reference not pre-selected by the candidate (obtained by the search firm through their independent network knowledge); and a commitment to follow up on specific concerns identified in principal references with an additional targeted reference if needed.

Obtaining References: Consent, Timing, and Process

Reference checking requires the candidate’s consent, and the process of obtaining that consent should be handled transparently from early in the assessment process. Candidates should understand from the initial process briefing that principal references — including at least one reference from outside their own nominee list — are a standard part of the appointment process. Surprising candidates with a demand for non-nominee references at offer stage creates unnecessary friction and occasionally results in candidates withdrawing because they are uncomfortable with the scope of the reference process.

Timing of references within the overall process varies. The most common approach is to conduct references on the preferred candidate only, after selection but before formal offer, making the offer conditional on satisfactory references. This minimises the reference burden on candidates who are not selected and protects the confidentiality of the process. An alternative approach — conducting references on all shortlisted candidates as part of the assessment — provides a more complete picture earlier but requires referees of all shortlisted candidates to be engaged, creating a wider disclosure circle and a larger reference burden.

Reference conversations should be scheduled as formal conversations of 20–30 minutes, providing the referee with advance notice of the specific topics to be covered. A brief preparation note — setting out the role being filled, the two or three specific capabilities being assessed, and the questions to be asked — sent to the referee 24–48 hours before the call consistently produces more substantive responses than cold reference calls where the referee has not had time to think through their recollections. Referees who are asked to participate without preparation tend to default to generic positives; those who have had time to reflect tend to provide more nuanced and specific responses.

The Reference Conversation: Structure and Key Questions

A structured senior reference conversation should cover the following areas systematically, in an order that builds from context to specific performance to summary judgement.

First, establish the context: how long did the referee know the candidate, in what capacity, and how directly did they work together? This calibrates the evidential weight of everything that follows. A reference from someone who worked closely with the candidate for three years as their direct manager is worth significantly more than one from someone who observed them at occasional meetings for two years.

Second, understand the candidate’s role: what specifically were they responsible for, what were the most significant challenges they faced, and what were the major decisions or initiatives they led? This context frames the performance discussion that follows and often provides specific examples that the interviewer can probe.

Third, assess strengths with specific examples: “What were the two or three capabilities that [candidate] demonstrated most consistently?” followed by “Can you give me a specific example of that?” Generic strength statements without examples are not assessment evidence — they are personality descriptions. The specific example is the unit of reference evidence.

Fourth, assess development areas with the same specificity: “Where did [candidate] have the most opportunity to develop?” followed by “Can you describe a situation where that showed up?” This is the question most referees find uncomfortable, and which most reference processes handle poorly — accepting the first vague response (“perhaps delegation”) without probing for the specific situation that would illuminate whether the development area is minor or material.

Fifth, assess performance on specific dimensions relevant to the role being filled: leadership, financial management, stakeholder relationships, transformation leadership, or whatever the two or three most critical capabilities for the specific appointment are. These role-specific questions are the most diagnostically valuable and the ones most commonly omitted from generic reference frameworks.

Finally, the summary judgement: “Would you rehire [candidate] for a comparable role?” This question has a simple binary that is difficult to avoid. A hesitation, qualification, or conditional in the answer is as informative as a direct “no.” Referees who are genuinely enthusiastic about a candidate answer it immediately and unequivocally.

Reading Between the Lines

Senior referees are typically experienced professionals who have given references before and understand both the legal constraints on what they can say and the professional norms around reference giving. Understanding how reference responses are shaped by these constraints allows the reference taker to extract more information than the literal content of the responses.

References that are warm but imprecise — “I enjoyed working with them enormously and they are a genuinely nice person” — without specific performance examples typically indicate a referee who is being carefully positive but has real reservations they are choosing not to articulate. The appropriate response is to ask more specific questions: “Can you describe a specific situation where they handled a difficult challenge well?” followed by, if still imprecise, “What situations did they find most challenging?”

Referees who describe the candidate’s performance exclusively in terms of outputs and results — “they consistently delivered the numbers” — without commenting on their leadership approach, team relationships, or management style are sometimes masking concerns about those dimensions. The specific follow-up — “How did the team respond to their leadership style?” — often produces more textured responses.

Pauses and hesitations before answering specific questions are informative. A referee who pauses before answering “Would you rehire them?” is giving as much information as their eventual answer. Experienced reference takers note the quality of responses as well as their content.

FCA Regulatory References

The FCA’s regulatory reference requirements under the Senior Managers and Certification Regime create specific obligations for both the appointing firm and the former employer. The appointing firm must request regulatory references covering the previous six years from all previous employers before the individual takes up a senior manager function. Former employers must provide regulatory references in a prescribed format using the FCA’s standard template, covering specific conduct matters: regulatory investigations and findings; disciplinary action related to fitness and propriety; and any conduct concerns that would be relevant to the FCA’s fit and proper assessment.

Former employers have a positive obligation to provide complete and honest regulatory references. A former employer that provides a misleading regulatory reference — omitting relevant conduct information to protect the departing executive’s future prospects — may face regulatory sanction. This obligation is enforceable and, in high-profile cases, has been invoked. Firms providing regulatory references should involve their compliance team in the reference preparation to ensure the obligations are met correctly.

Regulatory references are not performance references. They cover conduct and regulatory fitness matters — whether there are regulatory concerns about the individual’s fitness and propriety — not commercial performance, leadership capability, or functional expertise. Both types of reference are necessary for senior regulated firm appointments, and neither substitutes for the other. The companion SMF roles guide covers the regulatory reference requirements in the context of the full SMCR framework.

360-Degree References for Senior Appointments

For the most senior appointments — CEO, CFO, and board-level roles — some organisations commission a broader 360-degree reference process as part of the appointment due diligence. The 360-degree process extends the reference population beyond the standard upward references (former managers) to include peer references (former colleagues at the same level) and downward references (former direct reports), providing a more complete picture of the candidate’s leadership impact across all dimensions of the management relationship.

The 360-degree reference process for a senior appointment typically involves five to eight reference conversations across all three reference populations, conducted by the search firm or an independent reference checking firm, with a structured report provided to the hiring organisation. The additional investment — in time for the referees and in cost for the appointing organisation — is typically justified for CEO and CFO appointments where the appointment’s commercial significance is highest and where the cost of a failed appointment most clearly exceeds the cost of the reference process.

Background Checks Alongside Reference Checking

Background checks — verification of qualifications and professional credentials, criminal record checks, financial probity checks, and media and adverse interest searches — are distinct from reference checks but are typically commissioned alongside them as part of the pre-appointment due diligence process. For listed company director appointments, the disclosure obligations under the Listing Rules require specific verification of biographical information that is disclosed in the appointment announcement.

Professional credential verification — confirming that the candidate holds the qualifications they claim — is particularly important for appointments where specific professional credentials are material to the role. A CFO appointment at a listed company should verify ICAEW, ACCA, CIMA, or other accounting qualifications; a Chief Medical Officer appointment should verify GMC registration; a Chief Legal Officer should verify SRA admission. Qualification fraud — claiming credentials that are not held — is uncommon but not unknown at senior level, and verification takes little time and removes the risk entirely.

How Exec Capital Approaches Reference Checking

Exec Capital conducts structured principal reference checking as a standard part of every retained search engagement. Our reference conversations follow the framework described in this guide, with specific questions tailored to the dimensions most critical for each specific appointment. We provide clients with a written reference summary that presents the key findings from each reference conversation, identifies any patterns across references, and flags any specific concerns or development areas for the client’s attention in designing the induction programme.

References as an Induction Planning Tool

The most underused application of senior reference information is induction planning. A rigorous reference process produces specific, evidenced information about the appointed executive’s development priorities, their leadership style, the types of situations they find most challenging, and the management conditions in which they perform best. This information is of direct, practical value to the board chair, the CEO, and the HR Director in designing an induction programme that sets the executive up for success rather than discovering their development priorities reactively after they have already manifested in the role.

Reference information that identifies a consistent pattern — “they are excellent at external relationships but need strong finance support to manage the detail” — should translate directly into: ensuring the finance team reporting to the new executive is well-resourced and professionally qualified; planning a specific early conversation with the CFO about the financial management approach expected; and including financial management oversight as an explicit focus in the first board effectiveness review after the executive joins. This is constructive use of reference information — not as a reason to reconsider the appointment, but as a resource for managing it successfully.

Reference information about leadership style should inform team management planning. If the reference process reveals that the candidate is a decisive leader who can be demanding of their direct reports, the HR Director should proactively engage with the direct report team in the induction period to establish a constructive relationship before any management friction emerges. If references reveal that the candidate has previously struggled to build relationships with a specific function — finance, technology, HR — an early structured meeting with the equivalent function at the new organisation can prevent the pattern from reasserting itself.

Common Reference Checking Mistakes at Senior Level

1. Accepting the candidate’s referee list without question. Candidates provide referees who they are confident will be positive. Requiring at least one reference from outside the candidate’s list — obtained through the search firm’s independent network knowledge — consistently produces more balanced information than a list of candidate-selected advocates.

2. Treating HR confirmation of employment dates as a reference. HR departments at most organisations provide employment date and job title confirmation only, citing legal advice about reference liability. This is not a reference. A genuine reference requires a conversation with someone who has specific, first-hand performance knowledge. If the only “reference” obtained is an HR confirmation letter, no reference has been conducted.

3. Failing to ask follow-up questions. Generic positive responses without specific examples are not assessment evidence. The follow-up — “Can you give me a specific example of that?” — is the most important question in any reference conversation, and it should follow every response to a substantive question until a specific example has been provided.

4. Not probing the development area response. When a referee identifies a development area, the natural instinct is to move on quickly to avoid an uncomfortable conversation. This instinct should be resisted. “Can you describe a specific situation where that showed up?” and “How significant was the impact in that case?” transform a vague development observation into actionable information.

5. Conducting references too late. References conducted after the formal offer has been made — as a pure formality — produce either confirmation of what the organisation already believes (adding no value) or disconfirmatory information that is now much harder to act on because the offer is live and the candidate has given notice to their current employer. References belong before the formal offer, not after it.

Reference Checking for Board Appointments

Reference checking for NED and board chair appointments requires specific adaptation. The principal references for a NED candidate are different from executive references: they should include former company secretaries or general counsels who can speak to the candidate’s governance engagement and board contribution; former CEOs or CFOs whose boards the candidate has served on and who can assess whether the NED provided genuine challenge or simply endorsed management’s position; and former investment managers or PE partners who held board observer or director positions on the same boards as the candidate and who can provide a commercially-calibrated assessment of the NED’s contribution.

Investor references for NED candidates — conversations with PE investors, venture capitalists, or institutional shareholders who have observed the candidate’s board performance — are among the most valuable and most underused references in the NED appointment process. PE investors in particular have a frank and commercially-grounded assessment of board member effectiveness that is informed by the real consequences for their own investment returns. A PE investor who says “they were an excellent chairman of the audit committee and caught a significant issue with our cash management — we would absolutely appoint them again” is providing high-quality evidence of specific governance capability. The equivalent conversation with a former fellow board member who says they were “an excellent and collegial board member” is providing far less.

Managing the Reference Conversation Legally

Referees at UK organisations are often advised by their HR and legal teams to provide only factual, verifiable information in references — and to avoid any statement that could expose the organisation to a defamation claim. This legal caution has created a culture in which many corporate references are informationally limited by design, and senior executives giving references are sometimes advised to say nothing negative regardless of their actual assessment of the candidate.

The legal reality, however, is more nuanced. UK defamation law provides a qualified privilege defence for references given honestly and without malice in response to a genuine request for information. A referee who provides an honest assessment of a candidate’s performance — including performance concerns that are genuine and evidenced — is protected by qualified privilege as long as the assessment is honest and is not communicated beyond the specific reference recipient. This protection is broad enough to support candid references, and the “say nothing negative” advice that HR teams often give their executives is more conservative than the legal position requires.

Conversely, negligent misstatement — the legal principle that a reference given carelessly or misleadingly can give rise to liability to the recipient — creates a positive incentive for referees to provide honest, reasonably complete assessments. An organisation that provides a deliberately incomplete reference to help a departing executive move on — omitting material performance concerns — may face liability if that executive subsequently causes loss to their new employer in a way the reference, if complete, would have warned against. The Spring v Guardian Assurance case (1994) established this principle in UK law.

The practical implication for reference takers is that a referee who is clearly being very careful — sticking closely to factual statements, avoiding any assessment judgements, and declining to engage with specific performance questions — is often doing so on legal advice rather than from genuine reluctance. The appropriate response is to engage them directly: “I appreciate you may be providing a limited reference on advice — are there things you are not able to say in this format that you could share more informally?” A surprising number of referees, when given the opportunity to speak more freely, will provide the information they are genuinely willing to share but were not offering unprompted.

Exec Capital conducts all reference conversations in compliance with GDPR data protection requirements. Reference notes are treated as personal data of the candidate and are shared only with the hiring organisation’s designated contacts. Candidate consent is obtained for the reference process before reference conversations are initiated. Reference notes are not retained beyond the conclusion of the appointment process unless the client requires them for their own HR records.
