Use our secure online booking system to request your preferred date, time and location for a lie detector test.

Your Location - Step 1 of 5

Please utilize the straightforward booking system below to arrange a private test. Simply follow the instructions at each step, indicating whether you prefer the option of a test at our discounted-rate base offices or at one of our controlled offices accessible throughout the UK.

Our offices where we conduct lie detector tests are chosen based on their closeness to clients and their prior suitability. Typically, Controlled Environment Examination Offices are accessible within a 10-15 mile radius of your mainland addresses, ensuring convenience and professional settings for your needs.

To proceed and confirm your booking, we only require an upfront payment of a £100 booking fee (non-refundable). The booking fee is payable upon reservation and will be deducted from the total amount due at least 48 hours prior to the test.

The non-refundable booking fee confirms the customer’s intention to proceed with the booking and is used to cover costs we will have incurred, such as travel and venue expenses.

The booking fee is paid at the moment of the booking and then subtracted from the total to be paid a minimum of 48 hours before the test.

The nature of our work requires our examiners to be flexible and involves travel time and costs. Therefore we require a £100 non-refundable booking fee payment when you book your appointment.

The payment is non-refundable to ensure that the subject does in fact intend to take the test.

Without these measures in place, there is a temptation for a guilty party to book a test as proof that they have nothing to hide, and subsequently cancel the booking. Please be sure you or the test taker can, and intend to make the appointment when you book with us

We are a highly mobile polygraph service for client convenience, making ourselves available days, nights and weekends. This mobility requires us to be efficient in fee collection and scheduling. We would not be able to keep our fees so reasonable if after driving several hours, an examinee decided not to show up, leaving us with no work, no income and a long drive home. For these reasons, we do require £100 non-refundable booking fee WHEN you make your appointment.

Once an appointment is made, fees are non-refundable. You may certainly call for a free consultation at any time, we simply ask that you not schedule an appointment until you are certain you can make that appointment.

Experience precise, professional polygraph exams, cross-verified by accredited British Polygraph Society Examiners. If you require any assistance with your online booking or have any further questions, please contact our support team on 07572 748364

The Private Lie Detector Test

Our private lie detector test is specially developed to assist couples in learning the facts about their relationship

When there is an underlying element related to a specific event which may have happened, the lie detector test can identify the truth of the matter. Suspicion erodes trust and the test will either reinstate confidence or confirm a partner’s worst fears. Either way, both partners are able to move forward with their lives when they are in full possession of the facts. Our specialist polygraph examiners frequently deliver the infidelity lie detector test service to private clients all over the UK. Consistently the truth is established and our clients are able to make informed decisions based on the verified report they receive after the test. More often than not the report helps repair relationships rather than destroy them.

From start to finish the booking process was very simple and easy to follow. I had a examination with Mark in the cardiff location, who was very kind, understanding and compassionate in regards to my test reasoning. He was very clear on how the process worked, explained the equiptment, what would happen, and the process from start to finish. I received my results in less than 24 hours (although he did explain this is not always possible) I can now take a breath and focus on rebuilding my life. Thank you LDT. Your all a wonderful team.
