Lie Detector Test Preston

Yes. The Centre for Forensic Neuroscience provides confidential polygraph examinations in Preston and across Greater Lancashire, conducted by Dr Keith Ashcroft. Appointments are arranged after a preliminary consultation to confirm the suitability of the case.

All polygraph examinations are held in the strictest confidence. Results, charts, and reports are only released to the instructing party, unless there is a legal or safeguarding obligation to disclose information to relevant authorities. Please review our terms of business for complete confidentiality details.

Yes. Private examinations can be arranged at neutral, professional meeting spaces throughout Lancashire, including Leyland, Chorley, Blackpool, and Blackburn. We do not conduct examinations in residential settings to ensure the highest standards of reliability. If you decide to proceed, you may be asked to complete a confidential suitability questionnaire before your appointment. To discuss your case, contact Dr Keith Ashcroft.

Examinations can address specific, verifiable issues such as relationship disputes, allegations of theft or fraud, pre-employment security vetting, and legal or criminal defence matters. For a full breakdown of the protocols we offer, refer to our forensic glossary or contact us directly.

Polygraph examination fees in the UK vary depending on the nature of the issue to be investigated, the complexity of the case, the location of the appointment, travel requirements, meeting room or venue costs, and the professional time required.

At the Centre for Forensic Neuroscience, fees are quoted individually so that the cost reflects the actual work involved. A straightforward private examination may differ from a legally instructed matter, a therapeutic disclosure examination, a post-conviction sex offender assessment, or a workplace investigation.

Where possible, the fee will be confirmed in advance after a short discussion about the circumstances of the case. The quotation may take account of preparation time, travel, venue arrangements, examination time, reporting requirements and any necessary professional follow-up.

For solicitors, barristers, therapists, employers and organisations, fees may be quoted on a case-by-case basis or on a professional day-rate basis, depending on the nature of the instruction.

To receive an accurate fee estimate, please contact us with a brief outline of the matter, the preferred location, and any relevant timescales.

Yes. Questions are discussed and agreed before testing. Surprise questions are not used. Learn more about polygraph question formulation.

Yes, legal or solicitor-led enquiries may be considered where the scope is clear and the examination is suitable. A polygraph should not be treated as a substitute for legal advice or the court’s assessment of evidence. See our polygraph examinations for solicitors page.

A polygraph may assist in specific-issue relationship matters where both the scope and questions can be clearly defined. It is not a substitute for counselling, legal advice or safeguarding action.

All examinations must be taken on a voluntary basis. No person should be intimidated or coerced. If we believe coercion or threats are present, the instruction will be declined.

Examinations are conducted in a suitable, private and controlled professional venue in Preston or the surrounding Lancashire area. In line with APA recommendations, we do not conduct examinations in domestic (home) settings.

Examinees will be sent preparation information in advance. General guidance includes getting a normal night’s sleep, consuming normal meals, continuing prescribed medications and wearing comfortable clothing.

Yes. Complete the confidential enquiry form and the matter will be reviewed personally before an appointment is confirmed.

No. Each enquiry is reviewed to ensure that the proposed examination is suitable, fair and ethically defensible.

No. You may request initial contact by email, telephone, SMS or WhatsApp. Some matters may require a brief discussion before an appointment can be confirmed.

You may state your preferred office or location when submitting the enquiry. Availability will be confirmed after the case has been reviewed.

A specific-issue examination is normally restricted to no more than three carefully formulated relevant questions. Some cases involving separate issues may require more than one examination.

No payment is required merely to submit an enquiry. After the enquiry has been reviewed and accepted, a £125 reservation retainer is used to secure an offered appointment. It is a payment on account against the individually quoted examination fee, not the examination fee itself.
