Why Do We Take Non-refundable Advances?

Book your lie detector test with our non-refundable advances to receive guaranteed testing. You have to pay £150 in advance to proceed with the detection. Many payment methods are available here, from bank transfers and credit cards to any digital system.

Commitment to the Process

Taking our non-refundable deposit allows you to get immediate priority for our services. We make our examiner’s time, equipment, and other resources available to you with the certainty of your undergoing. This deposit maintains integrity from both sides for the polygraph test to proceed. Therefore, the non-refundable deposit enables us to provide our services in a reliable manner.

Securing Appointments

Polygraph examiners often have busy or occupied schedules. Their offices may be in high demand, as well. The sooner you make your non-refundable advance deposit, the more likely you will get a slot open. Because the examiner allocates a specific date and time for the test, the client gets the required attention and resources. So, non-refundable advancements help secure the right timing and environment for your test.

Protecting Against No-shows

We generally protect integrity with this strict procedure designed to discourage no-shows. No-shows not only waste slots but deny us the opportunity to serve genuinely interested clients with that appointed slot. The non-refundable advance is a deterrent against no-shows, as clients are less likely to skip the appointment when they have a financial stake in it. It encourages clients to honour their commitments or reschedule in advance, helping maintain a smooth and efficient operation.

Compensation for Preparation

The testing process starts right after you schedule your appointment. Conducting a lie detector test involves extensive preparation on the examiner’s part. This includes reviewing case details, formulating relevant questions, and calibrating the equipment. This preparation is time-consuming and requires expertise.

By requiring a non-refundable deposit, examiners can compensate themselves for this preparatory work even if you cancel or reschedule. It ensures that examiners are fairly remunerated for their professional efforts, regardless of the outcome of the appointment.

There are other administrative expenses, along with the cost of a lost client who probably won’t require the polygraph test again.

Factors That Make Polygraph Tests Expensive

Specialised Training

Polygraph examiners undergo rigorous and specialised training in psychology, physiology, and polygraph technology to be prepared to gain experience in their field. This extensive training contributes to the overall cost of polygraph tests, ensuring that a qualified and knowledgeable professional examines you.

Highly Skilled Examiners

Polygraph examiners must practise their nuanced skills concerning understanding human behaviour and physiological responses to be considered experts in this field. Since they must stay up-to-date in the polygraph industry, they must also maintain a solid record of successful tests.

It requires extensive experience and knowledge, which contributes to increased costs. And the fees associated with their services reflect their level of expertise and the value they bring to the accuracy of the polygraph test results.

Quality Assurance

It is important to ensure that the polygraph examiner you choose has a strong track record of accuracy and reliability. Many testing centres take quality assurance measures to guarantee that all tests are conducted with the utmost professionalism. Trained examiners, equipment maintenance, and specialised sensors are all necessary to ensure that polygraph test results are accurate.

Latest Technology

Polygraph test accuracy has also improved significantly in recent years due to technological advancement. Advanced sensors & machines are more sensitive and allow for better interpretation of responses, which can determine whether a subject answers truthfully. 

This improved technology comes with an increased cost that reflects its value. Continuous upgrading, maintenance, and equipment calibration are also necessary for quality assurance.

Limited Availability

Due to the specialised skills required of polygraph examiners, there are limited available in the UK; thus, their services command a price premium. Certified examiners do not come cheaply, and the fees associated with the test reflect this.

Agencies, too, can be expensive as they have a median rate that reflects the cost of keeping their company in business. The demand is high for these services, but the supply is not, so do not be surprised if you are quoted a steep fee.

Preparation and Analysis

It is important to remember that the cost of a lie detector test does not just encompass the time spent conducting it. Preparation and analysis also take considerable amounts of time and effort from the examiner, which should be reflected in higher fees.

From formulating questionnaires to interpreting results, much work goes into the process, and any good examiner will add all of these components to their fee.

Expensive Equipment

Types of equipment used in polygraph tests can be costly and must be regularly maintained. Since precision is paramount, examiners must have the finest tools available. You may need to measure psychological response, blood pressure, pulse, and respiration in one session, which can be expensive but ultimately worthwhile for the accuracy of results. Moreover, examiners require access to high-tech software that processes the data, so factor in all these components when calculating your costs.
