The short answer: no, not automatically. There is no rule in England and Wales, Scotland or Northern Ireland that makes polygraph or EyeDetect® results admissible evidence, and no court is obliged to consider a report or give it any particular weight.
That is a less commercial answer than you will read on some UK testing websites, and it is the accurate one. This page explains the position as we understand it, and where a report genuinely does help. It is general information, not legal advice — always take advice from your own solicitor about your case.
Lie detector evidence is not part of the ordinary criminal evidence toolkit in the UK. Guilt is determined on witness evidence, documents, forensic material and admissions, and a credibility test result is not treated as reliable scientific evidence of guilt or innocence.
Separately, polygraph testing does have a statutory role in the supervision of certain released offenders in England and Wales, used as a licence-management tool. That is a specific supervisory regime and it does not mean a test result becomes admissible evidence in an ordinary trial.
Civil and family courts have wide discretion over what they will admit and how much weight to give it. Some family practitioners do put test reports before the court in support of a client's account, particularly where an allegation rests on one person's word. Whether the report is admitted, and what the judge makes of it, is entirely a matter for the court.
For that reason the sensible order is: speak to your solicitor first, then book a test if it will help your case. Do not commission a test on the assumption that a court must consider it.
Most of the value in our reports is realised outside courtrooms. In practice they are used in negotiation, mediation, employment and disciplinary processes, family discussions and personal decision-making — settings where nobody is bound by rules of evidence and independent documentation counts.
Every report names the person examined, the date and location, the exact questions asked, the outcome for each question, the technology used and its 86-88% accuracy. It is written to be understood by a non-specialist and it does not overstate what a test can show.
If your solicitor wants to understand the methodology before instructing us, we are happy to talk it through with them at no cost.
Not automatically. No UK rule makes polygraph or EyeDetect® results admissible, and any weight given is at the court's discretion. Take advice from your solicitor before relying on one.
Some clients do put reports before family courts to support their account. The court decides whether to admit it and what it is worth, so discuss it with your family solicitor first.
Yes, in a narrow context: the supervision of certain released offenders in England and Wales. That is a licence-management measure, not a rule about court admissibility.
They are under no obligation to act on one. A private test is best used to support your own position and decisions, and with your solicitor's guidance.
It can support an internal investigation, but it should never be the sole basis for a disciplinary outcome. Employers should take HR or employment law advice.
We provide a clear written report and can explain the methodology to you or your solicitor. Whether a court hears that evidence is a matter for the court, and we make no promises about it.
