Why do Lie Detector Test Prices Vary?
The price of lie detector tests may be different from one provider to the next because of the number of factors. British Lie Detector Test UK normally charges an all-inclusive fee that falls somewhere in the region of £399 to £450 when booking directly with the company.
If third-party pricing exceeds your budget, you have the option to research and book directly with a private polygraph service provider like British Lie Detector Test UK.
When getting an estimate for a lie detector test, you should always make sure that the price includes everything and that there are no additional expenses on top of that.
Do You Need Multiple Lie Detector Tests?
It is normal for multiple lie detector tests to be needed, especially when there are multiple claims of cheating or theft in the same family or workplace. Our expert polygraph testers offer discounts for multiple tests, and our prices change based on current special deals, which are most common around holidays or events like Black Friday.
To ensure cost efficiency, we recommend conducting all required tests consecutively on the same day and at the same location, as this helps minimise expenses. Each test generally takes approximately two hours to complete.

What to Look for Before Booking Your Polygraph Lie Detector Test in the UK?
When choosing a polygraph service, it is essential to ensure that the examiners associated with or employed by the provider are accredited, fully qualified, and experienced.
Additionally, polygraph results should undergo peer review, similar to scientific research papers. Since lie detector test results can significantly impact a person’s life, a peer review process is essential to verify accuracy and reliability before finalising the results.

Examiner qualifications and accreditation
The level of training, certification, and experience of the examiner.
In the UK, the cost of a single-issue polygraph test typically ranges from £400 to £600, depending on the complexity of the case, geographical location, and any additional logistical or technical requirements.
While anyone can purchase polygraph equipment and claim to conduct tests, the accuracy and reliability of the results depend on the examiner’s expertise. A highly trained and accredited professional, certified by organisations such as the American Polygraph Association (APA), adheres to strict ethical guidelines and undergoes continuous professional development. In contrast, unaccredited examiners may lack the necessary skills and ethical standards to ensure accurate and unbiased results.
When booking a lie detector test, always verify the examiner’s qualifications and accreditation to ensure a professional, ethical, and scientifically sound examination.
Why Expertise and Accreditation Are Critical for Accurate Lie Detector Tests?
Just as you wouldn’t hire a plumber to repair your computer, selecting the right polygraph examiner is essential. Unqualified individuals exist in the industry, often offering services at suspiciously low prices. While not every low-cost service is unreliable, it is important to ask yourself: can you afford to risk inaccurate results when the outcome truly matters?
The qualifications and experience of a polygraph examiner directly impact the accuracy of the test. Choosing an examiner accredited by the American Polygraph Association (APA) ensures they have undergone rigorous training and adhere to strict ethical standards. They should also hold relevant academic qualifications, such as a degree in psychology, forensic psychology, or criminology, or have extensive investigative experience, often gained from law enforcement careers. Reputable polygraph providers do not employ examiners without these essential credentials. Former police officers, for example, bring invaluable investigative skills that align seamlessly with polygraph testing.
Even the most experienced examiners must have their results peer-reviewed before issuing a final report. This ensures that another equally qualified professional has validated the findings, providing the highest level of accuracy and reliability. When booking a lie detector test, always verify the examiner’s credentials, accreditation, and experience to ensure a scientifically valid and ethical process.
Beware of Fake Polygraph Examiners:
Why Ethics and Confidentiality Matter?
Lie detector test results occasionally surface in newspapers due to unethical examiners leaking confidential information. Such practices are strictly prohibited by the American Polygraph Association (APA). Only the individual who arranges and pays for the test has the right to disclose the results, though it is generally not advisable to do so. Unregulated examiners cannot always be trusted to maintain confidentiality, as some may be tempted to profit from unauthorised disclosures or even manipulate results for financial gain.
Confidentiality is a fundamental principle in the polygraph industry, particularly for private-sector tests. Clients seek lie detector tests to discreetly uncover the truth regarding sensitive matters, and professional examiners uphold strict privacy standards. Regardless of a client’s wishes, it is never the examiner’s role to publicise or share test results.
Polygraph examinations conducted by qualified professionals take place in controlled, secure environments, such as designated offices or, in certain cases, at the examinee’s home. Home tests are only performed when optimal conditions can be ensured, including the absence of alcohol or drug consumption prior to the test, a quiet setting, and no interruptions throughout the examination.
Ethical examiners maintain strict neutrality and discretion, ensuring confidentiality is never compromised.
The Real Cost of a Lie Detector Test:
Are You Paying for Accuracy or Regret?
As with any service, the quality you receive is often reflected in the price. Compromising on quality can lead to disappointment, so it is essential to research lie detector test providers thoroughly. Reviewing client feedback and verifying the qualifications of polygraph examiners will help ensure that you are selecting a reputable provider. If you seek accuracy and professionalism, be prepared to invest accordingly.
When evaluating reviews, consider their credibility. A provider with only one review on platforms like Trustpilot may appear to have a 100% positive rating, but a single review offers little insight into overall service quality. Due to the confidential nature of polygraph testing, most clients prefer discretion, meaning that polygraph providers typically do not amass hundreds of reviews. However, a provider with at least 10 reviews can give a reasonable indication of client satisfaction.
It is also important to recognise that not all reviews will be positive. Individuals who receive an unfavourable result may express dissatisfaction, leading to negative feedback. Additionally, the person taking the test is often not the one who arranged it, which can influence their perspective on the experience. When assessing reviews, consider the context and look for consistent patterns rather than isolated opinions.
