To proceed and confirm your booking we will require upfront payment of £125 deposit (non-refundable booking fee).

Once payment is received, you will receive confirmation of your booking via SMS and email.

Online payment *Terms & Conditions *

• I confirm that I have read and understood the terms and conditions, including that the £125 admin booking fee is non-refundable as it covers the administrative work required to manage the booking process and the pre-examination assessment. By proceeding with this payment, I agree to waive my right to a 14-day cooling-off period, acknowledging that the service will begin immediately once payment is received.

Confirm your booking

To confirm your appointment, only an initial non-refundable administrative booking fee of £125 is required, rather than full payment upfront. For more details on what this fee covers and our booking process, [click here].

The £125 non-refundable booking fee is required at the time of booking and will be deducted from the total cost of the polygraph test, leaving a remaining balance of £370 or £325, depending on your location. This fee confirms the client's commitment to the scheduled appointment and covers essential administrative costs, including securing preferred time slots, conducting pre-examination assessments, and assigning a qualified polygraph examiner.

Purpose and CommitmentThis booking fee ensures that clients are dedicated to their appointments, which minimizes cancellations and allows us to offer reliable service. The non-refundable nature of the fee also prevents misuse, as it discourages individuals from booking a test with no genuine intention of attending, simply to give the impression of having nothing to hide. Please book only if you or the test subject are fully committed to attending the appointment.

Cooling-Off Period WaiverBy proceeding with the booking, you agree to waive the standard 14-day cooling-off period under UK consumer law. The booking fee covers immediate administrative processes and pre-examination assessment arrangements, which commence as soon as payment is made. Therefore, the fee is non-refundable to account for these preparations and our commitment to providing efficient service.

Payment TermsThe remaining balance must be paid in full no later than 48 hours before the scheduled test date. Additionally, your completed Pre-Examination Questionnaire must be submitted prior to the appointment.

Refund Policy and Scheduling AssuranceOnce the appointment is scheduled, all fees are non-refundable, as these cover the time, resources, and expertise allocated to your case. By securing this payment policy, we maintain our competitive pricing while ensuring examiners are compensated for their time, particularly when extensive travel is involved. We invite you to call for a free consultation before booking, and we encourage you to schedule only when you are certain of your availability.

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.
