Private Lie Detector Test – Step‑by‑Step
The process is the same for every private client: consult, design, test, explain. Clear, repeatable steps so you know exactly what will happen on the day.
Confidential Pre‑Call
A private consultation to confirm that a P300 EEG test is appropriate for your situation, define the specific issue and explain realistic outcomes.
Question Design & Agreement
We work with you (and, if relevant, your partner or family) to agree a small number of clear, testable questions. Nothing is asked on the day that has not been agreed in writing first.
Private Appointment
You attend a single, private appointment. A lightweight headband is placed; there are no needles, straps around the chest or invasive sensors.
P300 EEG Testing
The subject views and hears controlled stimuli linked to the agreed questions. The system measures recognition‑linked brain responses in milliseconds.
Analysis & Result
Our software and examiner review the data, classify P300 responses and produce an outcome for each tested issue, with a clear explanation in plain language.
Written Report & Next Steps
You receive a concise written result and can choose to share it with a partner, family member, solicitor or therapist. Further support is available where needed.
Private Client Reviews
These examples reflect the type of private work we undertake every week – relationship, family and personal safety cases where clear, controlled testing changed the direction of a situation.
Relationship – Manchester
"We booked a private P300 test after months of arguments about suspected cheating. The process was calm and professional, and having a clear result allowed us to decide what to do next without guesswork."
Infidelity Concern – Birmingham
"Everything was explained before we arrived, including the exact questions. Results were ready around 30 minutes after the test and presented in a way both of us could understand."
Family Theft – Yorkshire
"Cash had gone missing in the house. The P300 testing gave us a neutral, structured way to deal with it. The examiner kept the atmosphere controlled and respectful for everyone involved."
Teen Behaviour – Glasgow
"We used a private test around suspected smoking and lying. Our teenager was treated with respect throughout, and the result helped us focus on the real issue instead of constant accusations."
Online Contact – London
"I needed clarity around hidden online messaging. The P300 test focused on specific events and accounts. The science was explained clearly so I understood what the result actually meant."
Household Dispute – Cardiff
"We had argued for months over missing property. The private session, agreed questions and written outcome allowed the family to move on instead of continuing the same argument."
Safeguarding Context – Edinburgh
"We used P300 testing as one element in a wider safeguarding situation. The examiner worked alongside our existing professional advisors and kept everything evidence‑focused and documented."
High‑Risk Dating – London
"Before making a major life decision, I wanted evidence about specific past behaviour. The private test and detailed report were worth it for the clarity and control it gave me."
Separated Parents – Leeds
"We used the test as part of a broader conversation around trust and parenting arrangements. Clear structure, no surprises and an honest explanation of what the result could and could not do."
Reputation & Career Risk – UK‑Wide
"As a regulated professional I needed every step documented. The P300 protocol, chain‑of‑custody notes and written explanation stood up well to scrutiny from my own advisors."
Private Lie Detector Test – Key Questions
Focused answers for private clients considering P300 EEG testing.
A private P300 EEG test uses direct brainwave measurement instead of straps and physiological sensors. The appointment is shorter, quieter and structured around a single, clear issue rather than a long list of questions.
By default, the result is released only to the paying client or the person named on the consent form. We will not discuss or share the outcome with partners, family members, employers or solicitors unless you have given written permission to do so.
Yes. In most relationship cases both partners attend. We usually brief you together, carry out the test with the subject and then agree how feedback will be delivered so that both parties understand the result in the same way.
Standard private appointments are usually available within a few days. Same‑day or next‑day slots may be available in Manchester and London, and on request in other cities, depending on examiner availability and travel.
- Get normal sleep the night before (7–8 hours).
- Avoid alcohol for 24 hours and recreational drugs for longer.
- Limit caffeine for 4 hours before the appointment.
- Take prescribed medication as normal unless your doctor advises otherwise.
- Wash hair normally and avoid heavy products on test day.
- Bring photo ID and any relevant case documents.
No lie detector test – P300 or traditional – replaces a court, judge or statutory investigation. P300 EEG can, however, provide structured, scientific evidence to support legal advice, mediation and internal decision‑making where expert evidence is considered.
Yes, subject to our written terms. We outline cancellation and rescheduling timeframes during booking so that private clients understand any fees linked to last‑minute changes, venue hire or travel.
P300 EEG focuses on involuntary recognition responses in the brain. The protocol is designed to make deliberate control very difficult. We also cancel or postpone tests where a subject is unwilling or unable to follow instructions, as this undermines the value of the result for everyone involved.
