About us



You’re here because you want the truth. And the truth is hard to get when you suspect someone is lying to you.

There’s nothing worse than the feeling you’re being lied to. It wrecks families, ruins workplaces and can even bring businesses down.

So you need somewhere to turn for help.

We have helped people in your position for many years. We have provided state-of-the-art lie detector tests internationally. You can be assured that our polygraph service is the most reliable and accurate on the market.

Our Mission

At British Polygraph Examiners we believe that offering an ethical and supportive service is the key to our success.

We are focussed on bringing the truth to light.

We realise that accuracy and reliability are our customer’s highest priorities and we will always deliver them. We do this by only using the best equipment and the best examiners.

We don’t cut corners. But at the same time, we are quick and efficient at getting to the truth.

Our Service

We are more than just a lie detector service.

We train all of our staff to excel at customer service. This includes offering friendly and supportive advice. We would never tell you how to handle a situation, but we are here to listen and tailor our polygraph services to suit your needs.

We take great care to employ the best examiners that are highly trained and qualified. They calibrate the machines regularly and are experts in designing questions for the test. They will talk you through the results and ease any concerns you might have.

Our main office is in London, but our service is mobile across the UK. When you book, you can choose any major town or city located in the UK. We have offices that we regularly lease across the country, or you can book your own venue if you prefer.

Unfortunately, there are some unscrupulous lie detector companies that operate using old technology that gives results no better than a coin flip. These companies exist only to exploit customers. Their examiners are often untrained. Some of them may be open to bribery.

Our tests are guaranteed to be accurate between 95-98%. All of our examiners can provide credentials and proof of qualifications if asked and operate with complete integrity.

Our customer's opinions are highly valued, so we always ask for feedback after a test. That way we always know how to improve our service.

Our Examiners

We only employ examiners that are trained to a high standard by the top polygraph training providers in the world. They are vetted carefully before coming to work for us. We are very selective about who we employ. Typically 80% of applications are rejected before coming to interview for a vacancy.

Once an examiner comes to work with us, we encourage and oversee their professional development rigorously. This helps them to deliver a top-quality service to you.

Our examiners:

  • Are qualifies and accredited by the American Polygraph Association (world-leaders in polygraph training)
  • Update their training regularly
  • Keep a professional development log which is audited
  • Undergo a criminal record check and regular background checks
  • Are trained in customer service
  • Guarantee discretion and sensitivity

Our Equipment

The hardware and software we use are constantly reviewed and upgraded. Lie detectors have become more and more accurate over the last few years. Our current polygraphs are accurate to 95-98%. We maintain and calibrate the equipment daily to ensure reliability.

Our Code of Practice

  • Polygraph reports are always an unbiased and impartial account of data gathered during the examination
  • Before the examination, enough time will be allowed to ensure that the examinee, and any third party involved, is satisfied with the examiner's understanding of the case and the prepared list of questions
  • Following the examination, the examiner will allow as long as necessary for any questions, doubts or reservations that the examinee and any third party involved may have regarding the report and the examination procedure itself
  • Unless relevant to the case, the examiner will not enquire of the examinee any information regarding their occupation or their religion, political persuasion or race
  • The examiner will hold and handle any information regarding the circumstances of each case in highest confidentiality
  • The examiner will refuse to carry out the test if they suspect that it is being used for unlawful purposes
  • Any attempt through bribery or other means to influence the examiner with the intent of undermining the credibility of the outcome of the test will result in the test being annulled without refund. Any third party involved in the testing or booking process will be informed of any such circumstances

  • The examiner will not accept money or any gifts which are intended to influence the examiner’s opinion
