Confidential Appointment Request
Request an Appointment
Requesting an appointment does not commit you to proceeding with a polygraph examination. Every enquiry is personally reviewed by Dr Keith Ashcroft to determine whether the matter is suitable and whether the proposed issues can be examined fairly, accurately and ethically.
You can request a confidential lie detector test in Inverness online without first telephoning. An examination is not confirmed until suitability, consent, question formulation and practical arrangements have been reviewed.
Appointment Reservation
Appointments are secured with a £125 reservation retainer after the enquiry has been reviewed and accepted. It is a payment on account against the individually quoted examination fee and is credited against the balance due. It is not the examination fee itself: the total fee is quoted after the nature, scope and professional requirements of the instruction have been assessed.

Learn MoreOur Commitment to Every Examinee
Preparation & Process
A transparent, step-by-step psychological assessment framework. We ensure all examinees fully understand the process, promoting maximum reliability.
Pre-Test Consultation
We review background case facts, confirm medical and psychological suitability, and explicitly discuss privacy, confidentiality, and consent boundaries before any testing begins.
The Pre-Test Interview
The most critical and comprehensive phase. The examiner thoroughly discusses every question to be asked during the exam. No surprise questions are ever asked.
Data Collection
Specialized, non-invasive sensors are attached to record biometric data (respiration, electrodermal activity, cardiovascular parameters) while the exact agreed-upon questions are asked.
Analysis & Report
The examiner analyses the physiological data using recognised forensic scoring methods. The findings are then communicated in accordance with the agreed scope of the instruction. Where a written report forms part of that scope, a confidential professional report is prepared.
Examinee Preparation Checklist

Fees and Venue Guidance
How Fees Are Quoted
Fees are quoted individually according to the nature and scope of the instruction. Relevant factors may include case complexity, preparation and document review, question formulation, examination time, venue and travel requirements, reporting and professional follow-up.
A straightforward private examination may require a different scope of work from a legally instructed matter, therapeutic disclosure examination or workplace investigation. Differences in fees reflect the professional resources required by each instruction, not a different level of methodological rigour. Solicitor, employer and organisational instructions may also be quoted on a professional day-rate basis where appropriate.
The fee will always be confirmed in advance, after a short discussion about the circumstances, before any appointment is agreed.
Examination Venues in the Highlands
Examinations in the Inverness area are conducted in suitable, private and controlled professional meeting rooms. The exact venue is confirmed directly with the client when the appointment is arranged.
In accordance with American Polygraph Association recommendations, we do not conduct examinations in domestic (home) settings, as it is rarely possible to control the environment to a satisfactory degree.
The date and time of examination are agreed between Dr Ashcroft and the instructing party during the initial consultation. Alternative venues may be arranged where required.
To receive a fee estimate, please contact us with a brief outline of the matter, preferred location and timescale.
