Your Location - Step 1 of 5
To ensure efficiency, we only accept appointments through our online booking system. Upon booking, you’ll receive an SMS and email confirmation. Booking online is the most efficient and optimal way to schedule a polygraph test. This method ensures a seamless experience from start to finish, eliminating potential delays and simplifying the entire process for our clients.
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.
Update: Limited slots in Scotland: If you require a lie detector test to be conducted in Scotland, please click here.

To proceed and confirm your booking, we only require an upfront payment of a £125 booking fee (non-refundable).

The booking fee is paid at the time of the booking and is then deducted from the total amount due.

The non-refundable booking fee ensures the customer's commitment to the scheduled appointment and supports the administrative costs associated with securing preferred time slots, conducting pre-examination assessments, and assigning a qualified polygraph examiner. This fee will be deducted from the full payment for the polygraph test. It's important to note that the full payment must be completed within 24 hours after the examiner approves the pre-examination assessment, ensuring your dedication and helping to minimize cancellations. 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

As a highly mobile polygraph service that operates day and night, including weekends, for the convenience of our clients, we must manage our scheduling and fee collection efficiently. To maintain our competitive pricing, it is essential to ensure that cancellations after long commutes do not result in lost work and income. Therefore, we require full payment no later than 24 hours after the examiner accepts the pre-examination assessment, in addition to the £125 non-refundable booking fee at the time of making 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.

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.
