What is the price for a lie detector test?

The price for a lie detector test varies, typically contingent upon where it is administered and the complexity of the issue at hand. At Lie Detector UK Services, a test costs £450 when conducted at one of our multiple office locations situated across major towns and cities in the UK. Alternatively, for those preferring the privacy and comfort of their own homes, the service is available at £550. Our prices, however, are subject to change, and for the most current pricing, please contact us directly.

We maintain strict ethical standards, professionalism, and discretion irrespective of the test location chosen. Dealing directly with us ensures no middle agency and allows verification of examiner credentials, enabling well-informed and calm decision-making. Avoid making bookings in the midst of disagreements, as advance deposit payments are necessary to secure bookings.

Pricing can also differ when multiple individuals are involved in a similar issue, potentially lowering the cost per person, such as in cases of theft suspects or couples opting for infidelity tests.

Be wary of exceedingly low prices that could indicate scams or exorbitantly high prices that could involve extra agency commissions. It is crucial to make decisions with a clear, calm mind and to be informed about who you are dealing with to avoid any inconveniences or misinterpretations.

Why is a non-refundable deposit required to book a test?
Our non-refundable deposit policy is a conventional norm within our industry and it serves crucial objectives. Primarily, it establishes an assurance of commitment from the client for the scheduled booking, thereby enabling us to dedicate appropriate resources and time to execute the test.

Secondarily, in the eventuality of a cancellation, this policy enables us to mitigate the incurred administrative expenditures and potential lost scheduling opportunities with other clients.

Furthermore, it is imperative to understand that polygraph testing is a sophisticated procedure, necessitating a significant level of preparation and proficiency from our examiners. The process incorporates comprehensive stages, including pre-test interviews, test administration, and detailed post-test analysis. Our examiners devote considerable time and resources into each examination.

By maintaining a non-refundable deposit requirement, we can safeguard the justified compensation for our examiners’ invaluable time and expertise, even when faced with unforeseen cancellations. This policy not only ensures a sustainable business model but also assures clients receive a service rooted in commitment and professional diligence.

What distinguishes a sexual contact lie detector test from a relationship infidelity lie detector test?

Although both can be used to resolve issues related to intimate relationships, the infidelity lie detector test focuses specifically on whether a partner has been unfaithful throughout the relationship, while the sexual contact lie detector test is appropriate when there has already been an admission of guilt but doubts remain about the extent of the intimacy, such as whether there was full sexual intercourse or other types of sexual contact.

While a question about sexual contact may be included in an infidelity test, the test is primarily focused on determining whether a partner has had an affair or been unfaithful, and it is up to the client to define what they consider to be cheating in the context of their relationship. During the consultation and pre-test interview, it is crucial to clarify the test’s objectives, and we will assist in focusing the questions to ensure a clear resolution.

Can I get a Free Lie Detector Test?

We do not offer free lie detector tests for a number of reasons. Our priority is the well-being of our clients, and providing free tests for the sake of publicity or views goes against our integrity. We believe that a lie detector test should be conducted with a serious and professional approach, and not for entertainment purposes. Additionally, offering credit services may suggest that a lie detector test is a solution to all problems, which is not the case. Our tests are accurate and thorough, but they work best when all parties involved are committed to resolving the matter at hand.

What Can You Expect on the Day of the Lie Detector Test?

Once you have confirmed your booking, we will send you a booking confirmation with details about when and where to arrive. When you arrive at our private and discreet location, simply provide your name to reception as we prioritize client confidentiality. Our examiner will meet with you and the person being tested (if not yourself) and escort you to a controlled studio.

At the studio, we will check your identification and ask you to sign a consent form. The test is video and sound recorded for analysis purposes. The examiner will then conduct a pre-test interview to gather facts and begin the psychoanalysis.

After the pre-test interview, the polygraph test will take place where the person being tested is connected to the equipment and asked a series of questions while their physical readings are recorded. Only the person being tested and the examiner will be in the room during this process.

The final part of the test is where the examiner will analyze the results and draw conclusions. The results will be provided to you verbally, and a full verified report with more detailed conclusions will be transmitted to you via email or post upon request. We respect your confidentiality and will only disclose the results to the person who made the booking unless instructed otherwise. If you wish to have someone verify that the test is credible, we will provide you with a pass code for third-party communication.

What are the requirements for the person being tested?

To ensure the most accurate results, the person being tested must abstain from alcohol or recreational drugs for 24 hours prior to the test. It’s important to disclose any medication they are taking at the time of booking, so we can advise accordingly. However, prescribed medication should be taken at their regular dosage.

How many questions may I ask?

Our polygraph tests adhere to formats that are recognized and approved by the American Polygraph Association. These formats have been extensively researched and are considered to be the most accurate, and they are used by law enforcement agencies and government departments in the U.K. and around the world. We use either a one question test format called the UTAH test, or a three question test format known as the AF/MGQT. As these formats have been developed to ensure the most accurate and reliable results, we are unable to deviate from them or permit additional questions.

Is the Lie Detector Test Accurate? Can it be Wrong?

The accuracy of the lie detector test has been proven to be between 95% and 98% by the American Polygraph Association, based on results from over 6,000 tests. However, the accuracy of the test relies on how well the test is controlled and administered. An experienced examiner, a controlled environment, up-to-date equipment, and necessary credentials all support a more accurate test.

It is essential to ensure that you book your test with a qualified examiner and that they conduct the test following a proven framework. A professional examiner will be able to report on and make accurate conclusions, ensuring that you receive the correct results. Be sure to check the credentials of the examiner before committing to a test. You can use the links on our website to the APA or contact us directly to ensure that the examiner is reputable.

How Does a Lie Detector Test Work?

The Lie Detector Test, also known as a Polygraph test, follows a controlled scientific experiment under a proven operating framework that combines the analysis of physical changes in a person while under questioning, with the principles of psychology. The test is conducted by a skilled examiner who measures changes in variables such as heart rate, breathing, and perspiration, in addition to psychologically evaluating the person being tested.

The psychological part of the test identifies specific issues and formulates a physiological profile of the examinee. The physical part of the test uses technical instruments to detect signs of deception and verification of the truth. The examiner combines the analysis from both the physical and psychological testing to draw conclusions and provide a professional report.

The Lie Detector Test is used globally in personal, criminal, and legal matters. In the UK, it is predominantly used to resolve personal matters like relationships, false accusations, and family disputes, with the success of such shows as Jeremy Kyle.

At Lie Detector UK Services, we strive to offer clear and transparent information to our clients. Our goal is to ensure that our customers feel confident that they are working with qualified and experienced professionals in the field of lie detector testing.

We believe that knowledge is essential, and our priority is to share it with those who seek our services.
