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.

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.

Cardiff lie detector tests

Cardiff is the Welsh capital. As well as being the largest city in Wales it has a lot to offer. It was the first Fair Trade capital in the world and enjoys more sunlight hours on average than Milan. Cardiff also has the most green spaces per capita than any other main city in the UK.

Known predominantly for its sport, mainly Rugby, Cardiff has the second largest stadium. Falcons can be seen scaring off pigeons and other small birds over its fully retractable roof. The Cardiff Blues have built a reputation as one of the greatest clubs in world rugby, due to the number of wins against international teams when touring. They’ve beaten South Africa, Australia and New Zealand has also failed to win against this spectacular club despite many attempts.

Cardiff is renowned for its impressive universities. In 2016-2017 the collective universities in Wales featured in The Times Higher Education World University Rankings, later also featuring in the QS World University rankings. People travel from far across the globe to attend these highly recommended resources for higher education. The universities have produced some of the countries greats such as Neil Kinnock, Adrian Chiles, Sian Phillips CBE and our favourite money saving expert Martin Lewis.

However, our polygraph examiners are aware of the price some students and athletes have paid for achieving outstanding results?

Smart drugs

More students nowadays are repeating a growing trend that started in China. Many of them are taking so called ‘intelligence enhancing drugs’ readily available on the internet. The practice has become quite popular here in the UK and has taken over the non-prescription use of Pro plus and caffeine for example. This growing trend starts with 1 in 10 of UK students using ‘smart’ drugs called Modafinil and Noopept. The latter was banned in the UK in 2016 as a non-prescription drug but can be purchased online. It’s illegal to sell Modafinil in the UK but not illegal to buy it online.

With the pressure on for students and athletes to do better than their peers, choosing the ‘smart’ drug route may seem appealing. However, in the long term they are not safe and can be highly addictive.
How Cardiff lie detector tests help

A large part of our polygraph examiners’ work in Wales relates to drug addiction. Our Cardiff lie detector tests are mainly ordered by parents concerned about their sons and daughters at universities. Few students admit to being addicted to a drug they shouldn’t be taking in the first place. Like other types of drug addicts they spend a lot of time in denial. But once addicted they are scared, finding it almost impossible to discuss the problem with anyone close to them. An admission to anyone at university could lead to them being expelled.

Polygraph examiners are always non-judgemental and completely impartial. Ours are also fully qualified forensic psychologists. Those addicted to drugs find it easier to discuss their fears with an unbiased stranger, who they may never meet again. Our Cardiff lie detector tests have helped many to overcome their addictions. The polygraph allows them to admit they have a problem to themselves and then seek the necessary treatment or counselling.
