A typical polygraph examination takes between two and three hours, including the pre-test consultation, the in-test data collection phase, and the post-test discussion.

The pre-test consultation is the most important and often the longest phase, during which every question is carefully discussed and agreed. The actual time connected to the polygraph instrument is usually less than 20 minutes.

Every polygraph examination is personally conducted by Dr Keith Ashcroft, Principal Forensic Polygraph Examiner. We do not subcontract to third-party examiners.

You will always know in advance exactly who will conduct your examination.

The pre-test consultation is the most important part of the process. It covers the background to the matter, confirms medical and psychological suitability, and explains the polygraph process in detail.

Crucially, it is during this phase that every question to be asked during the test is carefully formulated, discussed and agreed with the examinee.

No. Every question is thoroughly discussed and agreed with the examinee during the pre-test consultation.

No surprise questions are ever asked. This is a fundamental principle of professional polygraph practice and is essential to ensure that physiological responses are valid indicators of deception rather than surprise or confusion.

A comprehensive, confidential written report is produced where appropriate. Preliminary results are usually communicated during or shortly after the examination.

For legally instructed matters, the report can be prepared to a standard suitable for court proceedings or submission to relevant authorities.

Polygraph results are not currently admissible as evidence in UK criminal courts. However, they may be used to support defence case preparation, inform plea decisions, assist in family court proceedings, and provide investigative leads.

Dr Ashcroft is qualified as an Expert Witness and can provide reports prepared to forensic standards for use where permitted by the court.

Certain physical, psychological or medical conditions may make a person unsuitable for testing, including severe cardiovascular issues, respiratory disorders, acute anxiety disorders, psychosis, cognitive impairments, pregnancy or substance intoxication.

We also decline instructions where the purpose appears punitive, where consent is coerced, or where the matter cannot be framed as a clear, testable question relating to a past factual event.

Fees are quoted individually because costs depend on the nature and complexity of the issue, preparation time, venue arrangements, travel requirements and reporting needs. A straightforward private examination will differ from a legally instructed matter or a therapeutic disclosure session.

The fee is always confirmed in advance before any appointment is agreed. To receive an estimate, please contact us with a brief outline of the matter, preferred location and timescale.

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.

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. Once an appointment is accepted, a £125 reservation retainer is used to secure it and is deducted from the final examination fee.
