What we test
Private and business polygraph testing at 146 offices across the UK, by examiners accredited with the American and British Polygraph Societies.
Private & confidential
Infidelity, an allegation you can't disprove, something missing from the house. We listen first, and we don't press you to book on the call.
£495 for one person, or £695 for a couple
Business & legal
Stock going missing, a fraud investigation, screening for a role where trust is the job. Reports are written to stand up to scrutiny.
From £295 a person for group testing, minimum three
Client Focused Transparent Process Accredited Examiners
We are providing lie detector tests across the UK with a client focused approach. Together we are combining a wealth of experience, knowledge and high level execution with a regulated operating framework and strict code of ethics.
Prices
Every price below covers the accredited examiner, the pre-examination assessment, the examination itself and your peer-reviewed written report.
£495 all-inclusive
At any of our controlled offices across the UK — the price does not change with distance.
Couples & relationship testing
£695 a couple
Two people, tested on the same day at the same location.
Theft, business & legal
£295 per person
Three or more people, tested on the same day at the same location — all about the same case, with the same questions put to each person. £885 for the first three, then £295 for each person after that.
A £125 administrative booking fee confirms your appointment — not the full amount up front. It comes off the total, whatever the total is, and the balance is payable no later than 48 hours before the test. The £125 fee is non-refundable, and booking waives the standard 14-day cooling-off period, because the assessment work begins immediately. Read the full booking terms →
How it works
Nothing is booked, and nothing is paid, until you've spoken to an examiner.
Call the helpline and talk it through with our team — what happened, whether a test is the right answer, and what it would involve. No charge, no obligation.
Once booked, an examiner reviews your case and agrees the questions with you in advance. You'll know exactly what will be asked before the day.
Up to 4 specific-issue questions plus profiling questions, taking around two hours, at one of our controlled offices — a private room booked for your appointment alone.
A detailed written result, peer reviewed by a second qualified examiner before it reaches you. Yours to use as you need.
Where we test
Controlled examination offices in most major towns and cities, all at the same £495 — it does not change with distance, so choose whichever is easiest to get to.
All examinations are conducted in professional, disturbance-free environments at our private offices throughout the United Kingdom. A controlled setting is essential — polygraph testing relies on precise physiological measurements, and any interruptions or distractions can compromise the accuracy of the results.
Pick a region to see the towns and cities we examine in.
Recognised in UK law
Section 28 of the Offender Management Act 2007 lets the Secretary of State make a polygraph examination a condition of release on licence. HM Prison and Probation Service has run those examinations ever since, under a policy framework published on gov.uk — and Parliament has widened the power twice more.
These provisions concern conditions of release on licence, not evidence in criminal proceedings — a test you book with us is a private examination, not a legal finding. We are not affiliated with, endorsed by or acting for any government department.
Accreditation
Our examiners conduct examinations to the standards set by the British Polygraph Society and the American Polygraph Association — the world's leading body for evidence-based credibility assessment — and to the standards of practice of the European Polygraph Association.
The leading world body in polygraph testing. Every one of our examiners is accredited by the APA and graduated from an APA polygraph academy.
The UK body setting the standards and methods our examinations follow, and the code of conduct our examiners work inside.
The European body for polygraph practice and research. We are affiliated to the EPA and examine to its standards of practice.
Your data is handled confidentially and in line with the Data Protection Act.
Clients review us independently on Trustpilot, week in and week out.
Every examination is recorded on Lafayette hardware — the LX4000 in the photograph at the top of this page.
Proud supporters of the mental health charity, and we recommend them to anyone in distress.
