Frequently Asked Questions

How long does a polygraph examination take?
A full forensic polygraph examination typically requires two to three hours, depending on the complexity of the issue, the pre-test interview, and the number of questions tested. This includes informed consent, a structured pre-test discussion, the physiological data collection, and post-test procedures.
What areas of the United Kingdom do you cover?
The Centre conducts examinations across the United Kingdom, including London, Manchester, Birmingham, Leeds, Glasgow, Edinburgh, and other locations by arrangement. International deployment is also available where the matter is suitable.
Are polygraph results admissible in court?
The evidential role of a polygraph examination depends on the legal, regulatory, or tribunal context. Our reports are designed to assist investigations, legal strategy, disciplinary processes, and expert assessment, but polygraph evidence should not be treated as a standalone substitute for legal advice or wider evidence.
Can you provide expert witness reports?
Yes. Where appropriate, the Centre can provide structured reports explaining methodology, findings, limitations, and relevance to the instructed issue.
What happens during a polygraph examination?
A forensic polygraph examination follows a structured protocol: an informed consent process, a detailed pre-test interview to review the issue and agree the test questions, the physiological data collection phase using validated techniques, and a post-test review. A written report is provided to the instructing party.
How quickly can an examination be arranged?
Standard instructions are typically scheduled within one to two weeks. Urgent or time-sensitive matters can often be accommodated at shorter notice, subject to availability and suitability. Contact the Centre to discuss timing requirements.
Is every case suitable for a polygraph examination?
No. Suitability depends on the nature of the allegation, the examinee, the available evidence, the questions to be tested, and the legal or investigative context.
How confidential is the process?
Enquiries and instructions are handled discreetly and confidentially. Information is only used for the agreed professional purpose and subject to applicable legal, ethical, and data protection obligations.
