Accuracy of the test
How Accurate is a Lie Detector Test?
A trained examiner must explain the process clearly, prepare relevant questions, follow recognised testing procedures, and review the results using standard scoring methods. Professional polygraph equipment also records physiological responses such as breathing, cardiovascular activity, and skin conductivity during the test.
Research cited by the American Polygraph Association indicates that properly conducted polygraph examinations can reach accuracy levels above 90% in suitable conditions. However, no lie detector test should be treated as a guaranteed answer. The consultation stage helps confirm whether the situation suits testing and whether the questions can be framed clearly.
Lie Detectors UK uses a structured process to help assess truthfulness around specific agreed questions in personal, relationship, workplace, and private dispute situations.

Why Work With Lie Detectors UK?
Lie Detectors UK gives clients that clarity from the start. The service is led by Jason Hubble, combining named examiner expertise, professional equipment, real office-based appointments, and a structured process designed for sensitive personal and professional cases.
How It Works?
On the day of the test, you attend a full session that usually takes around two hours. The examiner begins with an in-depth pre-test interview to gather the relevant information, review the issue being tested, and make sure you understand the procedure.
The examiner then conducts the polygraph examination using professional equipment that records physiological responses during the test. After the examination, the examiner explains the results, talks you through the findings, answers any questions, and provides a detailed written report for your records.
To book a lie detector test in the UK, call the team or book online through the website.
A professional examiner speaks with you about the case, explains the process, and helps confirm the key issue for the test.
The team arranges the time, date, and appointment location based on availability and your requirements.
On the scheduled date, the examiner completes the pre-test interview, conducts the polygraph test, explains the results, and provides the written report.

Included
Features & benefits
Up to 3 Questions
Up to 3 Relevant Test Questions / Statements
We work closely with the client and any relevant stakeholders, including team members, decision-makers, and subject matter experts, to prepare clear, fact-driven test questions.
Each question focuses on the core issue being examined and avoids emotional, leading, or unclear wording. This helps keep the polygraph test fair, focused, and useful for the people who need to review the outcome.
By preparing the questions carefully before the examination, the process gives clients clearer information to support discussion, next steps, or decision-making after the test.
Same Day Testing
Same Day Testing Based on Availability
Please allow two hours for your appointment so the examiner can complete the test properly and give each stage the time it needs. No preparation is required on your part. Our experienced team will guide you through each step of the process, answer your questions, and help you understand what to expect.
We kindly ask that you avoid alcohol or illegal substances for at least 12 hours before the test, as these can affect the accuracy of your results.
Once the test is complete, we process your information promptly and, where available, provide your results on the same day.

After the examination, you receive a full written report at no extra cost. The report summarises the test, the agreed questions or statements, the results, and the examiner’s findings.
The examiner reviews the information gathered during the appointment, the polygraph data, and the context of the case before preparing the report. This gives you clear written documentation of the examination and its outcome for your records.
Group testing
Couple or Group testing with discounts
We offer discounts when multiple tests are required, making group testing more practical for individuals, couples, families, or businesses.
Group testing may be useful when several people are involved in the same issue, such as a theft case, workplace concern, family dispute, or relationship matter. The team confirms the number of tests needed, the appointment schedule, and the pricing before the process goes ahead.
Each test follows the same confidential and professional process, with care taken to handle every person involved discreetly.

Secure 24/7 Booking Easy Scheduling
You can use the secure online booking system at any time to start the appointment process. The team will then confirm the appointment details, location, availability, and any requirements before the test goes ahead.
Appointments are available from £399 at the Kent HQ. Other appointment options start from £499, depending on location and arrangements. This may include a home visit, a nearby office, or another suitable private setting where available.
Both options use clear pricing, with no hidden fees added to the agreed test cost. The aim is to make booking straightforward while giving clients a suitable setting for the examination.
Frequently Asked Questions (FAQ)
What is a Lie Detector test?
A lie detector test, also known as a polygraph test, is used to assess truthfulness around specific questions agreed before the examination.
During the test, the polygraph records physiological responses such as breathing, blood pressure, heart rate, and skin conductivity while the person answers. The examiner then reviews the recorded responses, the questions asked, and the context of the case before explaining the result.
Lie Detector test accuracy?
A single-issue lie detector test can reach an approximate accuracy rate of 92% to 94% when it is carried out by a trained examiner using suitable questions, recognised procedures, and professional polygraph equipment.
Accuracy depends on the quality of the questions, the examiner’s experience, the testing method, and whether the issue is suitable for a polygraph test. This is why the consultation stage is important before the appointment is confirmed.
Can a Lie Detector test prove my innocence in the UK?
A lie detector test can support someone who wants to respond to a false allegation by testing specific questions linked to the accusation.
It should not be presented as court proof of innocence, but it can provide useful supporting information for the person involved, their family, employer, partner, or legal adviser, depending on the situation.
Can an innocent person fail a Lie Detector Test?
An innocent person may feel nervous before or during a lie detector test. This is normal and expected. Nervousness alone does not automatically mean someone will fail.
A trained examiner looks at the full test process, including the agreed questions, the recorded responses, and the scoring method before explaining the result.
What does a Lie Detector test do?
A lie detector test asks a person a set of agreed questions while the polygraph records their physical responses. The purpose is to assess truthfulness around a specific issue, such as a relationship concern, false allegation, workplace matter, theft case, or private dispute.
After the test, the examiner reviews the results and provides a written report based on the questions asked, the answers given, and the recorded data.
Why do people fail Lie Detector tests?
People usually fail a lie detector test when their recorded responses indicate deception around the relevant questions, or when they withhold important information linked to the issue being tested.
The examiner does not rely on one answer alone. The result is based on the full examination process, including the agreed questions, the recorded responses, scoring, and professional review.
How long does a Lie Detector test take?
Please allow around two hours for your lie detector test appointment. This gives the examiner enough time to complete the pre-test discussion, review the questions, conduct the polygraph test, explain the result, and prepare the outcome clearly.
How much Is a Lie Detector test?
Lie detector test prices start from £399 at the Kent HQ. Other appointment options start from £499, depending on location and arrangements.
A £150 non-refundable deposit is required to secure the appointment. Please visit the pricing page for the latest prices, appointment options, and full booking terms.
Why Is a non-refundable deposit required?
A non-refundable deposit of £150 is required to secure your appointment. This reserves the examiner’s time, confirms the booking, and helps the team prepare for the test.
How do I prepare for a Lie Detector test?
You do not need special preparation before a lie detector test. The examiner will guide you through the process, explain what to expect, and review the questions before the examination begins.
Please avoid alcohol or illegal drugs for at least 12 hours before the test, as these can affect the examination.
Is there a minimum age limit for anyone taking a Lie Detector test?
Yes. The minimum age for taking a lie detector test is 18 years old.
What kind of questions are asked on a Lie Detector test?
The examiner works with all relevant parties to prepare suitable questions before the test. The questions must be based on facts, not emotions or unclear concerns.
A lie detector test will usually include three relevant questions asked over multiple charts. This helps keep the examination focused on the specific issue being tested.
How do you stay calm during a Lie Detector Test?
It is normal to feel nervous before or during a lie detector test. The examiner will explain the process, review the questions with you, and guide you through each stage before the test begins.
You do not need to force yourself to feel calm. The best approach is to listen to the examiner’s instructions, answer the agreed questions clearly, and ask anything you do not understand before the examination starts.
Does being nervous affect Lie Detectors?
Some anxiety is normal and expected during a lie detector test. Being nervous does not automatically mean someone is being deceptive.
A trained examiner understands that clients may feel anxious and reviews the full examination before explaining the result.
Will I feel pain during a test?
A lie detector test should not cause pain. The sensors are placed on the body to record physiological responses during the examination.
The blood pressure cuff may feel tight when it inflates, but this is usually the most noticeable physical sensation during the test.
Can you cheat a Lie Detector test?
Attempts to manipulate a lie detector test can affect the examination and may be identified by a qualified examiner.
The best approach is to follow the examiner’s instructions and answer the agreed questions honestly.
How do I know if I passed my Lie Detector Test?
After the test, the examiner will explain the result and provide a written report based on the questions asked, your answers, and the recorded test data.
This gives you a clear record of the examination and its outcome.
Can Lie Detector results be used in court?
Lie detector results should not be treated as guaranteed court evidence. If the test relates to a legal matter, court case, police issue, or solicitor instruction, speak to a qualified legal professional before relying on the result.
