The Lie Detector

The Lie Detector: polygraph testing and lie detection in the United Kingdom

The Lie Detector is a network of polygraph examiners and forensic investigators operating in the United Kingdom. The company presents itself as one of the most active lie detection services in the country and claims to have conducted more than 19,000 tests over more than 22 years of international work. Its head office is in Coventry, and it conducts tests at Regus network offices and at other locations hired as needed.

Polygraph services

The company structures its offering into several areas. In the private and relationship sphere, it addresses suspicions of infidelity, accusations of deception and family disputes. It also offers pre-employment screening tests, aimed at recruitment processes for positions of trust, and services for private or commercial investigations, such as cases of theft, fraud, CCTV enquiries or telephone records. In addition, it conducts tests for the judicial and prison system, including the assessment of sex offenders on parole, a programme regulated in the United Kingdom.

Media, film and events

The Lie Detector positions itself as one of the companies most used by the British audiovisual industry for lie detection services. It has worked on television adverts, programmes, film sets, radio, interviews, corporate demonstrations and special events, as well as school and university exhibitions. Among its media clients it mentions The Sidemen group.

Geographic coverage

The company serves clients throughout the United Kingdom and also conducts tests in Scotland and Ireland. For Scotland it uses hired offices in Glasgow or Edinburgh on specific days of the month, while in Ireland tests are carried out in Belfast. The head office is in Coventry, and in other cities Regus meeting rooms can be booked.

Methodology and equipment

Examinations are conducted with advanced digital polygraph systems, specifically the Lafayette LX6 model, and the company also keeps two analogue systems from the 1970s that it uses for social media clients and film sets. The polygraph is described as a diagnostic instrument that records physiological indicators such as blood pressure, pulse, respiration and skin conductivity while the subject answers a series of questions. The company cites an accuracy of up to 95% for this type of test.

Training and accreditations

The network's examiners were trained internationally and hold credentials from associations such as APA, BPS, EPA, ISOPE, SAPFED and ACFE. The company highlights having received advanced APA-accredited training, delivered by PEAK Credibility Assessment Centre (United States), for the assessment of post-conviction sex offenders, an area that in the United Kingdom requires specific qualifications and experience.
