Why Use a Polygraph?

If you need a conclusive answer to an issue or if you need to prove your innocence then a polygraph examination is the answer. A business polygraph can be used to resolve the following issues:

  • Theft
  • Fraud
  • False Claims (e.g. Insurance)
  • Sexual Harassment
  • Pre Employment Screening
  • Disproving False Accusations

North London Detectives use the same equipment as used by the United States & Canadian Governments. Our in-house polygraph examiners are trained to the highest standard at the New England Polygraphy Institute in the United States.
