Definition

Reference checking involves contacting former employers, managers or colleagues of a candidate to obtain additional information about their background, skills and professional behaviour. It validates the information provided and offers external perspective on past performance.

Legal framework and obligations

Legal obligations (UK law)

  • Explicit candidate consent

    Obtained in writing before contacting any references

  • Questions limited to professional competencies

    Respect of privacy and data protection laws

  • Strict non-discrimination

    Feedback cannot form the basis of discriminatory practices

  • Confidentiality of information

    Information subject to professional confidentiality

  • Data protection rights

    Candidate can request access to collected information

  • Secure retention of notes

5-step method for effective reference checking

  1. 1

    Selection and consent request

    Ask for 2–3 professional contacts (ideally former direct managers). Vary profiles: a manager, a peer, possibly a client. Obtain written candidate agreement before any contact.

  2. 2

    Interview guide preparation

    Prepare specific questions on key role competencies, strengths and development areas. Note context information before the call.

  3. 3

    Telephone contact

    Prefer telephone to email for richer exchange. A call allows you to detect nuances and revealing pauses. Introduce yourself clearly and explain the purpose.

  4. 4

    Interview conduct

    Ask open questions, listen for hesitations. Avoid closed questions. Note convergent or divergent points between references.

  5. 5

    Documentation and use

    Document feedback in structured format. Compare information across references. Identify discrepancies to clarify with candidate before final decision.

Tip: silences are revealing

During a telephone reference check, pauses, hesitations and careful phrasing often say more than explicit answers. Allow silences to linger: the most useful information often emerges after a pause. Don't automatically fill blanks.

Frequently asked questions about reference checking

When in the process should references be checked?
Reference checking ideally occurs in the final phase, after interviews and before hire decision, for 1–2 shortlisted candidates. Checking too early is time-consuming; too late, it cannot influence the decision. For sensitive or confidential roles, wait for the candidate's agreement about your hiring intention before contacting current employers.
Can a former employer refuse to provide a reference?
Yes, any referee can refuse to respond or limit themselves to confirming employment dates and job title. This is their right. Faced with refusal or evasive response, consider possible reasons. Some organisations' policies may prohibit managers from commenting on ex-employees.
How do you handle a negative reference about a candidate?
Don't take an isolated negative reference as absolute truth. Cross-check against other references and your own interview assessment. If negativity seems personal or lacks concrete facts, nuance its weight. If multiple references converge on the same critical point, it's a signal to explore deeply with the candidate.
Can you contact references not provided by the candidate?
Technically yes (LinkedIn allows finding common contacts), but proceed cautiously and ideally with candidate knowledge. Contacting unlisted references without their knowledge can cause complications, especially if the candidate's current role is confidential. Always stay within legal bounds and avoid harming the candidate in their current position.
Is reference checking mandatory for all roles?
It's not legally mandatory, but strongly recommended for management roles, roles of trust (access to sensitive data, finance) and roles where soft skills are determining. For junior or highly operational roles with low risk, you can adapt to a lighter version or make it optional.
