Polygraph Lie Tests

About the test

Our Forensic Psychophysiologists (polygraph examiners) use the latest equipment and techniques and are trained and qualified with the American Polygraph Association, the British Polygraph Association and the International Society of Polygraph Examiners.

Although polygraph tests are not usually admissible in UK courts, a judge can decide to take polygraph test results into account when adding to the weight of other evidence. Polygraph evidence has sometimes been used in UK industrial tribunals.

Appointments last about 1½ hours to 2 hours. Routinely, our examiners undertake appointments anywhere in England and Wales. Therefore, we ask you for a quiet venue that is uninterrupted for a minimum of 2 hours. It could be a private house or a hotel meeting room. It must be a quiet place, ideally with a table or desk and two chairs.

Medical matters

Sometimes, dependant on duration of pregnancy, examiners are able to test pregnant ladies. If you are pregnant, please advise us. The minimum age is 14 years old.

It is important that the subject is in a fit state to be tested. We ask that the subject to be tested consumes no alcohol on the day of the test and also no drugs for 24 hours prior to the test unless these have been prescribed or purchased from a pharmacy.

Prescribed medication may be relevant and our examiner will need to know what medicines are being taken at the time particularly if the subject has issues relating to heart rate or blood pressure. Please contact us to discuss this if you have any concerns.
