The nature of their work is to deal with people often in distress so in addition to these requirements, all of our examiners are trained to handle high conflict situations with the necessary interpersonal and communication skills.

Specialists in Private Matters

As a pre-requisite of handling private matters, we identify the key points of each individual test requirement and ensure that the most relevantly trained examiner is selected to conduct the test. An examiner will generally have one specialised area e.g. Infidelity testing, theft matters or at the other end of the spectrum sex offender testing and such. Our client support team are focused on making sure that the most relevant and suitable examiners conduct the your test.

We can provide private lie detector tests by professionally qualified examiners at discreet private office locations across the UK through our pre-mapped network of suitable nationwide locations. Our services are delivered by APA Accredited Examiners who have carried out rigorous training at the world renowned accredited polygraph schools. Our focus is on helping people to resolve private issues from relationships, false accusations to historical abuse and private theft. We do not conduct residential tests as in our opinion the test should be conducted in a controlled and suitable environment which is void of disturbance. Full and comprehensive reports are provided to further justify our findings and we provide them with every test that we conduct.

Our advanced polygraph test is accurate and professional. Our experienced examiners test the psychological signals with our state-of-the-art equipment measuring the physical signs. We always provide you with fully verified reports to substantiate our findings. Reports are always checked and verified by a second examiner so that you have a complete qualified opinion.

Our private lie detector can support you to discreetly resolve any intimate issues which may be causing a strain on your relationship and you can be safe in the knowledge that our work is strictly confidential. Our examiners specialise in resolving infidelity issues – whether specific to an accusation about someone in particular or historically trust problems.

Truth Verification Process

“The Private Lie Detector Test is a combination of Polygraph (Physiological) measuring and Psycho-Analysis through Forensic Psychology. The verification of the truth is determined from a number of factors and high accuracy is only possible through a combination of advancements in polygraph equipment and expert level psychology in deception. We conduct a high number of confidential criminal and legal test’s on a regular basis and the experience of our team of examiners is second to none.”

We always conduct suitability checks with all of our clients to make sure the private lie detector test is necessary and that they understand the process entirely. Most people we speak to have not or would not have experienced the process before so it is important that we are always transparent and informative.
