Sometimes you will find that prices differ between providers. This can be for a number of reasons. If you book directly with Lie Detector Test UK the average cost is £395 to £495 including VAT. However, if the test is booked through a third party such as a private investigator or solicitor the price may be higher. This is usually because the test forms part of a wider investigation. If the price is more than you wish to pay through the third party there is nothing stopping you researching online for a private polygraph service provider such as Lie Detector Test UK.

It’s not uncommon to want more than one test. This may apply when both partners in a relationship accuse each other of infidelity or when there is theft, either in the workplace or within the family. As reputable polygraph examiners we offer discounts on multiple lie detector tests. These vary depending on whether or not we have special offers on, usually around festive periods or Black Friday.

It is more economic to conduct all tests required, consecutively on the same day, in the same location. This keeps the cost down. The average time required for one test is around 2 hours.

If you have any queries about the cost of a lie detector test in the UK please contact us.

The most important thing to establish is that the polygraph examiners associated with or employed by a provider are accredited, fully qualified and experienced, together with the following:

A polygraph results report should always be peer reviewed in the same way as all scientific papers are. Lie detector test results can have life changing consequences and a peer review ensures optimum accuracy.

Often when you make up your mind that you want the truth, you want it quickly. Our secure, online booking system is available 24/7. Our customer service representatives are available on our Free Helpline Monday to Friday between 9 am and 8 pm and Saturday to Sunday you can get us on the phone from 10 am to 4 pm. All calls made to us are treated with the utmost confidentiality and you will not see us on TV. The polygraph is a serious, investigative tool that should never be used for entertainment purposes.

Sometimes you may not have the full fee immediately available. We offer payment options to allow you to find out what you want to know and pay later.

When you are quoted a price for a lie detector test, make sure that it is all inclusive with no hidden fees.
