FREQUENTLY ASKED QUESTIONS
All professional opinions and answers to our frequently asked questions have been provided by our accredited Polygraph Examiners. Should you have any further questions, please feel free to contact one of our examiners direct.
What is a Polygraph Test?
The Polygraph Test, (more commonly referred to as a Lie Detector Test) is an in-depth procedure conducted by trained and experienced polygraph examiners, using the latest in computerised polygraph systems and validated test techniques. A test can typically take a minimum of 2 to 3 hours, depending on the nature of the test. The term “polygraph” derives from the Greek words poly (many) and graph (writings), “many writings”.
Is a Polygraph the same as a “Lie Detector”?
Yes. The polygraph is a scientific diagnostic system which is often referred to as a Lie Detector or Lie Detector Test. A Polygraph simultaneously records physiological changes in the body when questioned in regard to a specific incident or event.
What Polygraph Examiner should I choose?
When choosing to go down the route of a Polygraph Test it is important to ensure you choose the right examiner especially when the outcome of a Polygraph Test can be life changed for some. We have therefore provided you with several factors to consider which should help you with the decision making.
A qualified and accredited Polygraph Examiner will have graduated from an accredited polygraph training academy. To verify the accreditation of a Polygraph Examiner, this can be confirmed by visiting The American Polygraph Association website.
Qualified Polygraph Examiners must first & foremost be registered with The American Polygraph Association. The majority of qualified polygraph examiners will be registered with a second and credible association such as The British Polygraph Association or The International Society of Polygraph Examiners.
As with all businesses and services, some companies and examiners will have more experience than others. Experience can be measured by the number of years an examiner has worked within the field of Polygraph and the number of tests they have conducted. Any Polygraph examiner should be happy discuss their experience and credentials with you.
Polygraph Examiners are required to comply with guidelines set by The American Polygraph Association of completing training every two years, as outline in their Continuing Education Policy. The policy is set out to ensure examiners are remaining current with advancements in polygraph science, research and technology.
EQUIPMENT & TECHNIQUES.
Polygraph Examiners should be proficient with using a variety of validated test techniques and should only use the latest in computerised polygraph systems. Equipment should be complete, fully operational and maintained to the highest standard.
A qualified and quality examiner should have adequate training and experience to identify the use of countermeasures, (attempts to "beat" the test).
A written report should be provided willingly and at no additional cost. A qualified and reputable Polygraph Examiner will be happy to put his/her opinions in writing.
What Polygraph Company should I choose?
From the outset you will notice that search results on the internet for Polygraph Test/Lie Detector Tests will return numerous companies appearing to offer the same thing. Therefore, it can be difficult for the consumer to know who to trust and what company to choose.
Polygraph Associations do not exist for the purpose of gaining “business” or “sales”, but exist as a gateway for the consumer to find factual information relating to Polygraph and to verify Polygraph Examiners accreditations and credentials.
There are several polygraph agencies who act as a third-party and often do not conduct polygraph tests themselves. These agencies will outsource independent Polygraph Examiners with usually higher fees than what can be achieved when booking direct with an independent examiner.
Independent Polygraph Companies:
The simplest way to check if a Polygraph Company is truly independent and not an agency is to pick up the telephone and ask. The person you speak to will more than likely be an examiner themselves. Any question you have should be able to be answered by them and without referring you to their website to find that information or checking and calling you back.
How much does a Lie Detector Test Cost?
As with all businesses and services, prices can vary depending on the location of the company, examiner experience, third party providers and the number of tests required. Typically, prices throughout the UK for one test, range from £395 to £595.
Prices can vary due to…
The location of the examiner:
Most companies are based within a particular region and therefore will have to travel to you. Additional costs such as meeting rooms and travel costs are to be expected but should not be exorbitant.
Cheap rates vs experience:
A lower cost may sound attractive and too good to pass up, however the cost should always be weighed up against the experience of the examiner. An experienced examiner will provide a professional and thorough service, catering to the needs of their clients, rather than their own.
Third Parties or Agencies:
Booking directly with an independent Polygraph Company is advisable as opposed to booking with an agency. The best fees are achieved by booking direct, as you will find agencies charging a higher rate only to outsource a Polygraph Examiner.
These should be provided and at no additional cost. If an examiner is unwilling to provide their findings in a written report, this is a red flag and should be questioned.
Test Techniques can vary due to the circumstance in which they are used for. Specific issue, incident or event tests such as infidelity or theft within the family home would require a different test technique to what would be used for business matters or when a larger pool of people is to be tested.

How accurate is a Lie Detector Test?
Although no forensic testing of any kind can be guaranteed to be 100% accurate, research gathered by The American Polygraph Association has suggested that qualified polygraph examiners can achieve an accuracy of 95% to 98% when an examination is conducted in an accurate manner, with issue-specific questions and using validated polygraph techniques.
Do you provide Lie Detector Tests on evenings and weekends?
Yes. Upon request, evening and weekend appointments are available but are dependent on availability and more notice is usually required. Please note: appointments are always necessary. We do not accept walk-ins, nor do we conduct tests without a confirmed appointment.
Will I know what the questions will be, prior to the test?
Yes. Each question that will be asked during the test will be read and explained to you before you take the actual test. There will be no surprise or trick questions, all questions are reviewed before the test is administered!
Will nervousness affect the outcome?
This is one of the more common questions asked and the answer is simply no. Everyone is at least a little nervous before taking a Polygraph Test, however the examiner conducting the test will assure the subject that they should not be concerned with being nervous. Nervousness is not interpreted as deception.
