What Should You Do When a Job Candidate’s References Do Not Match?

When references do not match a candidate’s CV, the discrepancy can change a hiring decision. It can also reflect a simple date error, a different description of the same role, or a former employer that only provides basic factual references.

Your first job is to establish exactly what conflicts. Do not turn one unexplained difference into a conclusion about the candidate’s honesty.

Start with the exact discrepancy

Put the candidate’s application, CV and reference beside each other. Identify the specific point that does not agree:

• employment dates;
• job title or level;
• duties and responsibilities;
• reason for leaving;
• qualification or professional status;
• identity of the referee;
• whether the organisation employed the candidate at all.

Record the wording from each source and the date on which you received it. This separates a real contradiction from a difference in terminology.

For example, a candidate may describe themselves as a team lead while payroll records use a different formal title. An employer may confirm only the start date, end date and last job title. Neither situation proves that the application was false. The question is whether the difference matters to the role and whether it can be verified.

A brief reference is not automatically a bad reference

Acas says that employers do not generally have to provide a reference unless a contract, regulated role or another agreement requires one. An employer that does provide a reference may choose how much information to include, and some organisations have a policy of giving only a basic reference.

That means silence about duties, performance or a reason for leaving is not evidence that the referee is concealing a problem. Ask whether the organisation has a standard reference policy before drawing a conclusion from what is missing.

Acas also says that a reference must be fair and accurate. A detailed reference can include relevant employment dates, duties, ability, current disciplinary information and a reason for leaving, but opinions should be supported by evidence and irrelevant personal information should not be included.

Check that the reference came from the right person

A convincing email address or letterhead is not enough on its own. Verify the organisation and the referee through a route that does not depend entirely on the contact details supplied by the candidate.

You can use the organisation’s official website or switchboard to confirm that the referee works there and is authorised to provide references. Check whether the email domain matches the organisation. If the employer no longer trades, record that fact and consider other evidence such as contracts, payslips, tax records or a reference from another manager, but request only what is relevant and necessary.

Do not mislead a person or organisation to obtain information. The Information Commissioner’s Office says recruiters must not obtain candidate information through deception. If a check requires a more intrusive enquiry, make sure it has a defined purpose and lawful basis before it begins.

Ask the candidate before you escalate

A candidate should have the opportunity to explain an inconsistency. The ICO’s recruitment guidance says that where an employer has questions about information provided by a candidate, it should contact the candidate. Acas similarly advises an employer to discuss uncertainty in a reference before withdrawing an offer.

Ask a neutral, specific question. For example:

Your application says you worked in the role from March 2022 to June 2025. The reference confirms May 2022 to April 2025. Can you explain the difference and provide any relevant supporting evidence?

Avoid accusing the candidate of lying or inviting them to disclose unrelated personal information. Keep the discussion focused on the point that affects the appointment.

Match the depth of checking to the risk

Verification checks information the candidate has supplied. Deeper vetting involves making additional enquiries about their background. Those are not the same thing.

The ICO says that pre employment vetting should be used where there is a legal obligation or where the employer can identify a significant and particular risk to the organisation, clients, customers or others. The check should be proportionate to that risk and should not become routine merely because more information is available.

A discrepancy about a qualification required to practise safely may justify more work than a minor difference in the title used for an earlier junior role. A senior appointment with access to money, sensitive information or vulnerable people may also justify checks that would be excessive for another position.

Explain the verification process to candidates early, collect only the information you need, apply the same decision rules consistently and keep a record of why each check was necessary.

Keep right to work and criminal record checks separate

A reference does not replace the checks the law requires. GOV.UK says you must check that a job applicant is allowed to work in the UK before employing them. The prescribed process may use the Home Office online service, original documents or an approved identity service route, depending on the applicant.

Criminal record checks follow separate eligibility and disclosure rules. Do not ask a referee to provide criminal record information as a shortcut, and do not treat a general background check as a substitute for the correct Disclosure and Barring Service route.

Decide only after the facts are clearer

Once you have checked the discrepancy, classify the result:

1. Explained and corroborated. The candidate provides a credible explanation and supporting evidence. Record the resolution and continue the process.
2. Unresolved but not material. The difference cannot be fully confirmed, but it does not affect a requirement of the role. Record the limitation rather than presenting it as a fact against the candidate.
3. Material and contradicted by reliable evidence. The candidate’s claim affects their suitability and the available evidence does not support it. Follow your recruitment policy and obtain employment law advice where necessary before changing or withdrawing an offer.

The wording of the offer matters. Acas explains that an offer can be made conditional on satisfactory references or other checks. Withdrawing an unconditional offer can create a different legal position, particularly once it has been accepted.

When can an investigator help?

A professional reference verification may be useful when:

• the referee’s identity or authority cannot be confirmed;
• the employer has closed or changed ownership;
• employment dates, duties or seniority conflict across several sources;
• a required qualification or professional claim needs independent confirmation;
• the appointment carries a defined financial, safeguarding or information security risk;
• your internal team cannot resolve the discrepancy through ordinary reference checks.

The investigator should confirm the purpose, permission and scope before starting. The report should state what was checked, what was confirmed, what remains uncertain and which sources support the findings. The hiring decision remains yours.

UKPI’s reference verification service is designed for conflicts in employment history, references and professional claims. For a wider check before appointment, see the pre employment checks service and the Evidence Room guide to pre employment screening.

Prepare the evidence before you ask for help

Keep the candidate’s application, CV, reference, relevant correspondence and a short note identifying the exact discrepancy. Record which facts have already been confirmed and which remain assumptions. Do not send unrelated personal information simply because it is available.

If a reference conflict affects a current appointment and ordinary checks have not resolved it, use the confidential enquiry form to explain the discrepancy. UKPI can assess whether reference verification is proportionate before you commit to an investigation.
