Edinburgh Polygraph

Edinburgh Polygraph is a provider of accredited lie detector examinations operating in Edinburgh and across Scotland. They conduct confidential, APA-standard polygraph tests for individuals, couples, employers, and legal matters. The business is now part of Lie Detector Test UK, which they describe as the UK's largest polygraph provider, while maintaining the same examiners and venue in Edinburgh.

The total price for an examination is £495 per person, which includes a £125 pre-examination assessment fee paid online and an examiner's fee paid 48 hours before the appointment. This fee covers the consultation, the full computerised examination, independent scoring, and a same-day written report. There are no add-ons or hidden costs according to their pricing policy.

Examinations are conducted at a Regus serviced office located at 9–10 St Andrew Square, Edinburgh, EH2 2AF. Appointments are strictly by appointment in controlled and discreet conditions. The office is described as a professional, central, and discreet location for the tests.

To get started, clients can call the business at 0800 008 6365 for a free, no-obligation, and completely confidential conversation. Alternatively, they can book an examination online at any time through the website. The first conversation commits the client to nothing and is used to understand their situation before any fees are due.

The business serves clients across Edinburgh, the Lothians, and the whole of Scotland. They offer specific services including relationship and infidelity testing, pre-employment screening, theft and workplace investigations, false allegation defence, and legal or solicitor-referred cases. Each partner in a relationship is examined privately and separately.

The examination process involves a pre-test consultation, a computerised test of around 60–90 minutes, and time to review the results. The entire appointment is estimated to take around two hours in total. The instrument records physiological responses like respiration, electrodermal activity, and cardiovascular activity while questions are answered.

The business states that their methodology follows American Polygraph Association validated techniques adapted to UK practice and law. They use modern computerised instrumentation that records several physiological channels at once. Charts are scored independently rather than on impression to ensure reliability.

The examiners are accredited by the British Polygraph Society and work to its code of ethics and standards of practice. This accreditation ensures the examination is conducted to a recognised UK professional standard. The examiners are trained, insured, and answerable to an independent body.

The website mentions that the typical booking turnaround is within 24 hours, though confirmed bookings are made within one business day. Clients can also arrange evening appointments by arrangement. The business aims to confirm appointments quickly after an online booking request.

The business emphasises that attempts to manipulate the test, known as countermeasures, are far less effective than commonly suggested. The most reliable result comes from arriving relaxed, well-rested, and honest. A trained examiner is alert to any manipulation attempts during the process.

The business states that their accuracy, when tests are carried out correctly by a trained examiner, is in the region of 90–98%. This high reliability depends heavily on technique, the quality of the pre-test interview, and correct scoring. Accreditation is cited as a key factor in ensuring this level of accuracy.

The business operates on a fixed fee model with a clear price of £495 per person. They state there are no small print clauses or hidden fees. The price is structured to provide transparency, covering everything involved in a complete, professionally conducted examination.

The business operates Monday to Saturday, including evenings by arrangement. They offer a free, no-obligation conversation for those who prefer to talk first. The contact phone number is 0800 008 6365 and the email is [email protected].
