You can request a confidential lie detector test in Leeds 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.
Why Choose Our Leeds Lie Detector Test Service?
The Centre for Forensic Neuroscience has provided lie detector tests in Leeds and across West Yorkshire for over two decades. Our polygraph examinations are conducted to the standards of the American Polygraph Association (APA) and are led personally by Dr Keith Ashcroft — one of the most experienced forensic polygraph examiners in the United Kingdom.
Whether you are a private individual seeking clarity on a personal matter, a solicitor preparing a case, or an employer addressing a workplace concern, our Leeds service is designed to be thorough, discreet and professionally managed at every stage. We specialise in relationship and domestic matters, criminal defence assessments, and workplace investigations.
All examinations take place in a suitable, private venue within the Leeds area. In accordance with APA recommendations, we do not conduct polygraph tests in domestic settings.
Leeds is the largest financial and legal centre in the UK outside of London, with a concentration of major law firms, banks, and corporate headquarters in its city centre. This thriving professional services economy drives significant demand for polygraph testing in corporate fraud, employment disputes, and due diligence investigations.
Core Polygraph Services in Leeds
We provide specific-issue polygraph examinations for individuals, solicitors, employers, therapists and safeguarding professionals across Leeds, Bradford, Wakefield, Huddersfield, Halifax, Harrogate, York and the wider West Yorkshire area. Every examination follows APA standards and a structured, transparent process.
Private & Relationship Matters
Confidential polygraph examinations addressing specific disputed incidents between partners, family members or associates. These assessments are investigatory in nature and provide structured, evidence-based information to support decision-making — they should be considered alongside other evidence and, where appropriate, professional counselling.

Solicitors, barristers and legal professionals can instruct the Centre for credibility assessments in criminal, civil, family and immigration matters. Cases involving allegations of sexual abuse are subject to enhanced procedures with two forensic polygraph examiners. Dr Ashcroft is qualified as an Expert Witness.

Polygraph examinations for private-sector employees under investigation for specific allegations of theft, fraud, misconduct, insider threats or breaches of trust. We also provide pre-employment screening for roles where trust and security are paramount.

We support safeguarding professionals through the child sex offender disclosure scheme and conduct post-conviction sex offender polygraph testing (PCSOT) in conjunction with therapists and probation officers. These examinations assist in managing risk to children and vulnerable adults and support treatment compliance in the community.
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 analyzes physiological charts using sophisticated forensic scoring algorithms. A comprehensive, confidential written report is subsequently produced.
Examinee Preparation Checklist

Fees and Venue Guidance
How Fees Are Quoted
Polygraph examination fees are quoted individually because the cost depends on the nature of the issue, the complexity of the case, preparation time, travel requirements, venue or meeting room costs, and reporting needs.
A straightforward private examination will differ from a legally instructed matter, a therapeutic disclosure session, or a workplace investigation. For solicitors, employers and organisations, fees may be quoted on a case-by-case or professional day-rate basis.
The fee will always be confirmed in advance, after a short discussion about the circumstances, before any appointment is agreed.
Examination Venues in West Yorkshire
Examinations in Leeds are conducted at Regus Leeds - The Pinnacle, 67 Albion Street, Leeds, LS1 5AA. This professional venue provides a private, controlled environment suitable for polygraph testing, with meeting rooms specifically configured for forensic examinations.
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.
