Lie detector tests, also known as eye-detect examinations, are becoming increasingly sought-after across the UK for a range of purposes. From settling personal conflicts to helping with legal cases or workplace inquiries, these tests are prized for their ability to expose the truth in delicate circumstances. Among the first questions you probably have if you are thinking about a lie detector exam is: how expensive is it? The cost can change depending on location, the type of test, and the service provider; hence, the response is not always clear-cut.
