The benefits of using a private lie detector test and how to book one with Lie Detector Test UK across the UK.

One of the main benefits of using a private lie detector test is that it can provide clear and definitive answers to questions of infidelity, theft, or other issues. It can bring closure to individuals who are suffering from uncertainty and doubt and can also provide important information that can be used to make decisions about the future of the relationship or in legal proceedings.

Another benefit of the test is that it is conducted in a confidential and controlled environment, ensuring that all information is kept private. This is particularly important for individuals who are concerned about their privacy and the potential consequences of their test results being made public.

My partner passed the test with questions about cheating with a specific person, a few weeks later she admitted to me that they have been intimate with one another and she apologised and said she don’t know how she passed the test.

Just feel let down that I put my hard working money to not get the truth.

Reply from Lie Detector Test

This is a very unusual review. In over 15 years of conducting polygraph examinations, we have never had a situation like this where a client later claimed the result was wrong but did not contact us directly so we could investigate it.

Polygraph testing is not 100% infallible, and no responsible examiner should claim that it is. Validated single-issue examinations are highly accurate, with some validated techniques reporting accuracy levels of around 95%, so while an incorrect result is possible, the circumstances described here would be very unusual.

We asked this reviewer for a booking reference or any other details that would allow us to identify the examination, review the exact questions asked, examine the charts and speak with the examiner. We received no response.

At this stage, we therefore cannot verify that this review relates to a genuine client or an examination carried out by our service.

For anyone considering credibility testing, we would always recommend a properly conducted, evidence-based polygraph examination by a trained examiner rather than relying on newer or less established alternatives such as eye-tracking or automated “lie detection” systems.

Polygraph testing itself is certainly not a novelty in the UK. It is the same type of testing used by HM Prison and Probation Service. Section 28 of the Offender Management Act 2007 provides for polygraph testing as a licence condition for certain offenders, and its use has subsequently been extended through further legislation. The Probation Service has been using polygraph examinations with certain sexual offenders for more than a decade.

If this reviewer is a genuine customer, we are still more than happy to investigate the matter properly. Please contact us directly with your booking reference so that we can review the examination.

I went to polygraph results today

I went to polygraph results today At lie detector test uk and Met a lovely guy, Marc who explained the process. He put me at ease. Great experience from start to finish. This firm is highly recommended. I was so scared but I absolutely 💯 smashed it 99.9% pass. I was let down by another firm with the eye lie test. I have sever dyslexic so having the questions asked & answering myself rather than the button on an eye detector test was so much better. I highly recommend 👌 the company & Marc for all the help you gave me. Explaining step by step means the world to a person with dyslexicia 5 🌟 thanx Kelly 👍

I recently took a lie detector test in the UK and the experience was highly professional from start to finish.

The results were delivered promptly and with a detailed explanation, showing real expertise and transparency.

Organised Test with Justin

Organised Test with Justin

Went to test with partner and we were supposed to watch results of video and we didn’t get shown.

Complaining and then he tells me he cannot deal with me due to data protection, yet he was happy to ask for my bank details as I was paying for it.

Then had to cancel due to partner having a medical emergency for abscess in his mouth, said pay another £300 and that will fine. Gets to the test and then he asked for a further £300. This test has cost me over £2000 for one person and still no further forward as we haven’t seen any evidence. I am now complaining and said I cannot deal with me, but no problem dealing with me when he was asking for money to be paid. Make sure he explains everything clearly about watching video as evidence as this is what you are paying for.

I understand you don’t get to keep video, and when I have asked for them to send audio, so will update soon to see if Justin sends it the audio

We are no further forward and bring together for 32 years and this has now caused us more harm and a lot of stress and no clarification apart from a piece a paper which isn’t worth the paper it’s written on.

Scammers

Scammers - Bad way of doing business - test paid £450 and booked for today at 4pm was told I would need to confirm with them on the day, I work nights so advised them when they call I may be asleep so I may not be able to confirm but I will be 100% attending and asked them to leave a note on system stating this. Woke up at 3pm (I live in close proximity to the test location) called straight away as soon as I woke up and they told me they have cancelled my test and will be keeping the total £450. They said they tried to call several times to confirm but I was asleep so couldn’t confirm earlier on in the day. Really bad way of doing buisness as if they were trustworthy would’ve used them again, really disappointed with my service now no test and out of pocket £450

Thank you for sharing your feedback, and we're sorry to hear about your frustrating experience.

We've carefully reviewed our records and booking systems regarding this situation. Our confirmation policy exists specifically to protect both our clients and examiners—polygraph appointments require significant preparation, travel arrangements, and dedicated time slots that cannot be filled at short notice if a client doesn't attend.

When bookings are made, we clearly communicate that same-day confirmation is required to proceed with the appointment. This is standard practice across the polygraph industry, as no-shows create substantial operational challenges. While we understand you work night shifts and communicated this, our system requires verbal confirmation on the day to ensure the appointment will definitely proceed.

**However, we genuinely want to work with you to find a resolution.** If you can provide us with your booking details, we'd be happy to review your specific case and explore options that might include:
- Applying your payment toward a future appointment with a more flexible confirmation arrangement
- Discussing alternative scheduling that better accommodates your work pattern

We recognize this situation has been disappointing for you, and while our policies are in place for important operational reasons, we're always willing to have a conversation about individual circumstances.

Please contact us directly with your booking reference so we can discuss how to move forward in a way that works for everyone.

We appreciate your understanding and hope we can still provide you with the professional service you were seeking.

10 out of 10. Outstanding professional service

I had an outstanding experience with lie detector test UK. My examiner was Marc who was so professional at what he does, he guided me to ask the right questions as I was a difficult client who couldn't grasp it but he had so much patience and guidance and I wouldn't have got the answers I was looking for without him. I would also like to mention Jo, the telephone advisor who spoke to me with such care and humanity, I felt like I knew her personally which put me at ease throughout the process. Jo was very down to earth and helped me with every enquiry I asked for. I couldn't thank them both enough and im sure we will be back for another test as there has been a lot of lies, he failed all 4 questions so thank you again for my clarity and helping me move forward to getting the truth.

Absolutely Golden Standard. Start to Finish.

Absolute gold standard service from start to finish. My examiner was Marc, he was very welcoming and made everything crystal clear, step by step, and made the whole thing flow well.

I'd recommend them to anyone, we had the results a few hours after finishing the test in Exeter.

We were about to cancel our wedding over a rumor, but we took a lie detector test at Lie Detector Test UK before doing something we would regret. The truth came out, the lies were exposed, and the wedding is back on!

We appreciate your feedback and understand that failing a lie detector test can be an emotional experience. However, we stand firmly by the accuracy and integrity of the results. The questions were agreed upon in advance and conducted using industry-standard procedures by a qualified examiner.

While it can be difficult to accept the outcome, our responsibility is to deliver the truth based on physiological data, not to provide a result someone hopes for. It's also worth noting that your partner, who arranged the test, is satisfied with the outcome, appreciates our professionalism, and has left us a 5-star review in support of the process.

We understand this may be upsetting, but we will not issue a refund for a result that did not meet your expectations. In the future, the best approach to avoid this situation is to be completely truthful—both with yourself and others. The polygraph is a powerful tool for uncovering the truth, and it's most effective when approached with honesty.

Our goal is to help people find clarity, even when the truth is difficult. We remain committed to that mission.
