How much does the test cost and does it vary according to the number of questions asked?

This is one of the most frequently asked questions we get. The price of a polygraph test is not dependent on the amount of questions you want the subject to be asked, and here’s why.

A lie detector test will become ineffective if too many questions, or too many different questions, are asked. When you see a tv show in which the examiner asks question after question after question, you should know that the show is for entertainment purposes – the results will not be accurate.

Let me explain this further; a polygraph test should only ever be used to gain the truth about one issue. Only one. Each question should be regarding the specific issue. This way, if the subject answers dishonestly on any of the questions he will fail the entire test because all the questions are related to that one, single issue.

Polygraph testing prices across the UK range from £500-£750 per specific issue exam, and the average fee is about £600. (for real polygraph, not voice stress toys used over a phone or other sub-standard tests) We do not use voice stress “toys”. If voice stress had the provable reliability and validity that Polygraph does for lie detection, we would be using it.

We are a professional polygraph examiners and only conduct examinations in accordance with testing procedures and protocols recognized by the American Polygraph Association. We will not conduct substandard examinations. A properly conducted polygraph examination will result in accuracy rates of 95 to 98 percent whereas an improperly conducted examination will result in accuracy rates that are no better than the flip of a coin.

Each session can take anywhere from 90 minutes to three hours to complete, but to answer the initial question ‘No, the price does not vary according to the number of questions asked’, because we will only ask the amount of questions needed to ensure an accurate result.

How to schedule a polygraph test in the UK?

To make a booking you can either use our website or call our head office directly. We provide polygraph testing all over the UK. In order to confirm your order, it is required to pay a deposit of £300. Once the deposit has been paid, on the same or next day you shall be contacted by our examiner who is responsible for the chosen location.

All we care about is accuracy, not how fast we can do your examination, however we strive to offer appointments as soon as the following day from when the order being placed. In a vast majority of cases we are able to arrange a test within a 1 – 3 days of the order being placed. The sooner you get in touch, the sooner we will be able to conduct your examination.

Why is a non refundable deposit required?

The non-refundable deposit 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 deposit is paid at the moment of booking and then subtracted from the total to be paid on the day of the test.

The nature of our work requires our examiners to be flexible and involves travel time and costs. Therefore, we require a £300 non-refundable deposit 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 £300 deposit payment WHEN you make your appointment.

Once an appointment is made, fees are 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.

There are some polygraph examiners who cost less than you. Why is that?

The answer to this question is simple and applies to almost everything in life – you get what you pay for! That is not intended as a flippant answer, but it is the simplest explanation. We use the most advanced, most accurate equipment available to us in order to ensure the best, most reliable results.

Some polygraph examiners will be using out-dated equipment and achieving less-accurate results, and this will, of course, be reflected in their pricing.

Furthermore, we spend a lot of time making sure we get to the truth – we could lower our fees and spend less time with our clients, but we refuse to sacrifice our integrity.

Please remember there are examiners out there that sell on cheap price, low amount of questions, and will come to your home. These are not on a highly reliable or properly conducted polygraph examinations. Be careful. You get what you pay for. It’s like finding a cheap surgeon or attorney.

When choosing a lie detector test, you should consider the reliability of the results above all other concerns. Polygraph test performed correctly using the latest the latest equipment and qualified examiners will return results with 95-98% accuracy.

Unfortunately, commercial polygraph examination is not regulated by UK Law. This allows less than credible firms to operate. These firms often use outdated and unethical techniques and results from low quality firms will often have less than 65% accuracy and can be as low as 50%.

Don’t decide your future on the flip of a coin.

Why does it take so long?

Every single case we have is as important as the last, so the time spent on putting you at ease, making sure you know the process and explaining the importance of honesty is time well spent because it ensures that we get the most accurate results possible.

On the surface that does seem like a long time, but the actual polygraph test will usually take the least amount of time. The majority of the time will be taken up by us talking. We will discuss the issue at length, which means we can ask the most pertinent questions possible, which in turn gives the most accurate results. We need to make sure you are physically well enough for the test, and that you understand the difference between lying and telling the truth.

You will have the opportunity to tell your side of the story in full, and, once we have compiled a list of the questions to be asked you will be told what those questions are before the actual test begins. Once the polygraph examination is completed, we will then give you the results and discuss them before you leave. It is quite a lengthy procedure but it does go by quickly!

Can I have a Polygraph Test at Home?

The simple answer to this is, no. The offices we use are specifically geared towards accuracy in the polygraph – at home, there are many distractions, such as family pets, interruptions from the phone or doorbell and other family members. No matter how well you try to prepare your home, life happens, and unfortunately, that will get in the way of a lie detector test.

Our offices are neutral bases – there are no ties, no memories or emotions attached as there would be at home, and as accuracy is paramount we will only hold the examinations there. However, we do have offices at many locations across the country.

What happens if someone tries to beat the test?

Many people think they can beat the polygraph test, and in older versions of the test it was possible. However, with today’s technology, there are measures in place to detect any attempt to tamper with the test. Moreover, you would not only be up against the equipment, but you would also be trying to fool highly experienced and trained examiners, people who are well aware that some will try to beat the test.

What if someone who is charming and persuasive tries to fool you?

Ok, so of course people can be charmed, and polygraph examiners are not immune to personality. The equipment, however, is immune! So even if your examiner is fooled by someone who is lying, the involuntary responses which occur will still be recorded on the monitor.

Polygraph examiners know they are only human and therefore look to the equipment for clarification. Any examiner will override their gut feeling that someone is innocent when the equipment tells them otherwise. Similarly, an examiner could draw the conclusion that a subject is guilty just by their mannerisms, but be proved totally wrong when the equipment shows that they are, in fact, innocent.

Anyone can search on the internet for ways to beat a lie detector – however, it would take someone who is highly practised and skilled to successfully achieve that. Most polygraph testers, who have been working with this technology for years and know exactly how it works, would not be able to beat the test.

Our equipment is highly sophisticated and is designed to detect attempts at manipulating the test. So really, in answer to the question, it is highly improbable that anyone, no matter how personable they are, could fool the polygraph.

Why would anyone who is guilty agree to take a lie detector test?

If a person refuses the chance to clear their name using a polygraph, that alone suggests guilt. Furthermore, most people will assume that you are just bluffing when you ask them to take one and agree because they don’t actually believe you have access to the equipment to back it up.

Can nerves make me look guilty when I’m not?

This is a situation which has been exploited (unsuccessfully) by many people who think they can beat the polygraph. Nerves will NOT affect the outcome of the examination, and for good reason. If you are nervous at the beginning of the test, as most people are, you will remain nervous throughout the test. Your reactions to answering truthfully and deceitfully will still differ and will still look very different to each other, thus giving us a clear indicator of guilt or otherwise.

How long will I have to wait for the results?

The subject will be given the results verbally immediately after the test, once they have been scored. If required, a written copy of the results can be posted. We are also happy to call and discuss the results with an interested third party to whom the subject wants the results to be known.

How accurate is a polygraph test?

This is a much-debated question and one which we have answered in depth elsewhere on our website. Accuracy depends on many factors, and for details on those, you should have a look at the page which deals specifically with that. However, the American Polygraph Association will tell you that a properly conducted session, with specific questions (as opposed to the many questions we discussed earlier), will give a result of between 95% to 98% accuracy.

I’m on prescription medication from my Doctor. Do I need to stop taking them?

Definitely not! Not taking your prescription drugs could be dangerous, and in fact, could interfere with the test. The vast majority of prescription drugs will not interfere with the accuracy of the test as we need you to be as ‘normal’ as you would be on any other day.

Does it hurt?

No. You may feel a slight discomfort or pressure from the blood pressure cuff on your arm, which is inflated for the duration of the test, but it is no more uncomfortable than if a nurse or Dr was taking your blood pressure. In fact, the cuff will be slightly less inflated than in a medical situation, so discomfort should be minimal, if at all.

Is there a minimum age limit for someone taking a polygraph test?

The short answer would be no. However, in order for the test to be accurate, the subject does need to possess a good level of language and to understand the concept of truthfulness. Some children under the age of 12 may not possess that comprehension, so younger people are screened on an individual basis.

I’d like to sit in on the test. Can I do that?

if you have brought someone to us for a lie detector, you being in the room, watching and listening, is almost guaranteed to distort the truth. Let’s face it, not many people will want to admit their guilt with their accuser sitting next to them, or even listening in! Most people find it easier to admit guilt to a stranger – that’s why counselling is so effective! So no, as much as we understand that you would want to sit in and hear what is being said, your presence would undermine the effectiveness of the test.

What about Voice Stress Tests?

Voice stress testing is not as accurate or reliable as polygraph testing, so we do not use it in our examinations.

Do I need to come to a central office for a polygraph test?

We realise that one location will not be convenient for many people, so to that end we do travel to various locations across the country, as long as a suitable venue is available.
