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 the East of England 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. Payment instructions are provided with the appointment confirmation. The reservation retainer is deducted from the final examination fee.
Professional Lie Detector Tests Across the East of England
The Centre for Forensic Neuroscience has provided professional polygraph examinations across the East of England for over two decades. Every lie detector test we conduct is personally carried out by Dr Keith Ashcroft, Principal Forensic Polygraph Examiner — a chartered investigative psychologist with extensive experience in forensic psychophysiology and credibility assessment. We are an independent forensic practice, not affiliated with any agency, party or commercial chain.
Our examinations are conducted from professional consulting facilities throughout the region, providing a confidential, controlled environment suitable for forensic testing. We follow an evidence-led methodology grounded in the standards of the American Polygraph Association (APA) and ASTM International Committee E52 on Forensic Psychophysiology. Every examination incorporates structured question formulation, careful pre-test consultation and rigorous data analysis using peer-reviewed scoring techniques.
Our East of England polygraph service is used by solicitors and advocates, barristers, corporate investigators, private individuals, therapists, families and employers. Whether you are dealing with a relationship dispute, responding to a false allegation, investigating workplace misconduct or preparing a legal case, we provide the same structured, transparent methodology for every client. For more about our approach and professional background, visit our about page.
Coverage extends from the academic centre of Cambridge to coastal Suffolk and Norfolk. We maintain access to Regus Businessworld consulting facilities in multiple cities, and can often arrange suitable professional venues elsewhere on request. To understand more about polygraph methodology and what the research tells us, see our guide on how polygraph examinations are evaluated.

Professional Consulting Facilities Throughout the East of England
As a Regus Businessworld member, Dr Ashcroft has access to a network of professional consulting facilities across the East of England. This membership provides access to private meeting rooms and consulting suites in city-centre business locations throughout the region, ensuring that examinations are conducted in a professional, controlled environment appropriate for forensic psychophysiological testing.

Confidential Consulting Rooms
Private, soundproofed meeting rooms configured for confidential forensic examinations.

Why Clients Choose Dr Keith Ashcroft
Many clients who contact us have already researched polygraph testing and have made a deliberate decision to travel to one of our East of England locations rather than select the nearest available examiner. The reasons are consistent: they want to know exactly who will conduct their examination, they want to understand the methodology in advance, and they want confidence that the process will be handled professionally from start to finish.
Dr Ashcroft’s professional reputation has been built over more than two decades of forensic practice. As a chartered investigative psychologist, his approach draws on a specialist background in forensic psychology, investigative methodology and psychophysiological assessment. This is not a side business or franchise operation — polygraph examination is the core of a dedicated independent forensic practice.
Independence is central to the service. Dr Ashcroft is not connected to any party, agency, solicitor firm or commercial interest. This independence means that results carry greater weight with legal professionals and investigators who need to be confident in the objectivity of the examination and the examiner. Every examination follows a clear, structured methodology with careful question formulation and thorough pre-test consultation.
Crucially, Dr Ashcroft is a named examiner. Clients know in advance who will conduct their examination, can verify his professional qualifications and memberships, and deal with the same person from initial enquiry through to report delivery. For guidance on evaluating polygraph examiners, see our article on how to choose a polygraph examiner in the UK.
