What Is Included in the Lie Detector Test Price?
Your lie detector test price covers more than the actual test. It includes the key stages needed to prepare, conduct and explain a professional polygraph examination properly.
Pre-Test Consultation and Interview
Every appointment begins with a private pre-test consultation and pre-test interview. The polygraph examiner reviews the issue, explains the testing process and prepares suitable questions.
A standard examination can include up to three relevant questions or statements. The questions are clear, focused on one issue and agreed before testing begins.
Professional Polygraph Examination
The price includes the polygraph examination conducted by a qualified examiner using professional equipment.
During testing, the equipment records physiological responses including breathing, heart rate, blood pressure and changes in skin conductivity. A blood pressure cuff and other sensors are used to record these responses while the person answers the agreed questions.
Allow around two hours for a standard appointment, including the pre-test interview, preparation and examination.
Same-Day Results and Written Report
Your results are explained on the same day. A full written report is included in the agreed test price and is usually provided on the same day following the examination.
There is no separate charge for the standard written report.
What Does the Lie Detector Test Cost Cover?
When comparing the cheapest lie detector test with a professional service, check what the quoted price actually includes. A lower headline price may not tell you whether question preparation, professional examination or a written report is included. At Lie Detectors UK, the agreed price covers the complete testing process described above.

Why Professional Polygraph Testing Costs More Than a Basic Appointment
Specialist Polygraph Equipment
Professional polygraph testing relies on equipment that records physiological responses such as breathing, heart rate, blood pressure and skin conductivity.
The equipment requires maintenance, checks, servicing, calibration and replacement of components where necessary. These costs form part of operating a professional polygraph service.
Examiner Training and Professional Standards
A trained examiner needs specialist knowledge before conducting professional examinations. Examiner training can include physiology, psychology, interviewing techniques, question preparation, instrumentation and recognised polygraph procedures.
Lie Detectors UK works with accredited examiners, including Jason Hubble, Director of the UK Polygraph Association and an experienced examiner affiliated with the American Polygraph Association.
Practical Experience
Polygraph testing requires professional judgement as well as equipment.
An experienced polygraph examiner must know how to prepare suitable questions, manage the pre-test interview, conduct the examination and analyse the recorded responses.
This is particularly important when dealing with nervous clients, relationship disputes, false allegations, workplace investigations and other sensitive circumstances.
Quality Review and Documentation
Professional polygraph services should follow a clear process from the initial consultation through to the written report.
The price therefore reflects more than the time spent conducting the actual test. It covers preparation, examiner experience, confidentiality, testing conditions, analysis and documentation.
It’s advisable to request a conversation with the examiner themselves to discuss your case before proceeding. This direct interaction can often clarify misunderstandings, address specific concerns, and potentially lead to a more favorable outcome without further formal steps.
Why Choose Lie Detectors UK?
Qualified and Accredited Polygraph Examiners
Your test is handled by experienced examiners trained in professional testing procedures.
Lie Detectors UK works with APA and UKPA accredited examiners, including Jason Hubble, who has over 12 years of polygraph experience and is Director of the UK Polygraph Association.
Clear Question Structure
A professional polygraph examination depends on suitable questions.
Questions should:
- require yes or no answers
- focus on one main issue
- avoid vague or subjective wording
- avoid questions about feelings or emotions
- be easy for the person taking the test to understand
- remain directly connected to the issue being examined
The examiner works through these questions with you before the test begins.
Your enquiry, appointment details, examination information and results are handled discreetly. Privacy and confidentiality apply throughout the process.
The Maidstone HQ appointment costs £399. The £150 non-refundable deposit forms part of that total rather than being an extra cost. The remaining balance is payable on the day of the appointment. There are no hidden fees added to the agreed test cost.
The £399 HQ examination takes place at the Lie Detectors UK Maidstone office in a private and controlled setting. The testing environment matters because distractions, question preparation, examiner handling and equipment setup can affect the quality of a polygraph examination.
Where more than one test is required, pricing is confirmed according to the circumstances, location, urgency and complexity. For larger or time-sensitive cases, more than one examiner may be available where appropriate. Separate tests can then be organised efficiently while maintaining privacy and professional testing standards.
Lie Detector Test Pricing FAQs
How Much Does a Lie Detector Test Cost in the UK?
A lie detector test at the Lie Detectors UK Maidstone HQ costs £399. Other appointment arrangements start from £499, with the final price depending on factors such as location, travel, urgency and complexity.
Why Is a Non-Refundable Deposit Required?
A £150 non-refundable deposit is required to secure your appointment. It forms part of the total test price rather than being an additional booking fee.
The remaining balance is payable on the day of your appointment.
Is the Written Report Included?
Yes. A full written report is included in the test price, with results explained on the same day.
Will Nervousness Make Me Fail a Polygraph Test?
Feeling nervous or anxious before a lie detector test is normal. The examiner doesn’t determine the result simply because someone feels nervous.
The pre-test consultation, question preparation and testing process allow the examiner to prepare the person and establish appropriate testing conditions before the examination begins.
Can I Have a Lie Detector Test at Home?
A home visit or another appointment outside the Maidstone HQ may be possible depending on your location and circumstances.
The location must provide a suitable private and controlled environment for professional polygraph testing. Outside-HQ appointments start from £499, with the total fee confirmed before booking.
Is a Lie Detector Test 100% Accurate?
No polygraph test is 100% accurate. Validated polygraph tests can achieve 87% – 96% accuracy when conducted correctly by a qualified examiner. Accuracy depends on factors including examiner training, question design and testing conditions.
Can I Pay by Credit Card or Use a Payment Plan?
Lie Detectors UK does not currently offer a formal payment plan. You can pay the deposit upfront and the remaining balance on the day.
Credit card payments are accepted if you prefer to pay by card or spread the cost through your card provider.
Why Does an Appointment Outside the HQ Cost More?
Appointments outside the HQ may require additional travel, location arrangements, privacy checks and examiner scheduling.
This is why the cost can be higher than the fixed £399 Maidstone HQ appointment.
Are Discounts Available for Multiple Tests?
Where multiple tests are required, the price is confirmed based on the location, appointment arrangements, urgency and complexity.
This can apply to workplace investigations, theft cases, family disputes or other situations involving several people.
Can More Than One Examiner Be Arranged?
Yes, where appropriate. More than one professional examiner may be available for larger or time-sensitive cases, helping several separate tests to be completed efficiently.
