How a Mallow P300 EEG Test Actually Runs
The practical detail clients ask about most: where in Mallow the test happens, what the day looks like, what the written report includes and how payment works. Everything below is the same whether you book a single test or a two-person visit.
Home Visit in Mallow
Prefer to do this at home? The examiner comes to you, anywhere in Mallow or the surrounding area. The 4-channel BrainBit EEG kit sets up on an ordinary table in a few minutes. All we need is a quiet room for around 90 minutes.
Private Venue in Mallow
Rather not have it at home? We arrange a reserved suite at a Mallow town-centre or Springfort-side hotel, booked in our company name and confirmed to you in writing. Corporate premises also accepted for workplace investigations. Strict confidentiality from the front desk.
The Mallow Day
A pre-test interview, the P300 EEG examination itself, a short debrief and the analysis. Allow 60-90 minutes for the appointment plus up to an hour for the written report, which is handed to the paying client before they leave the venue.
The Report
8-page forensic report — raw waveform data, P300 spike analysis per probe question, deception score breakdown, methodology summary, signed certificate of examination. Issued only to the paying client; never copied or shared.
Confidentiality
The Mallow venue is booked under our company name, not yours. The examiner arrives in plain clothes with unmarked equipment cases. Nobody at the venue is told what the booking is for. Records are handled in line with GDPR.
Payment
Priced and charged in euro by card, so your bank makes no conversion. Enquiries can also be settled by SEPA, Wise or bank transfer. Book and pay online, or agree a date with us first and pay once it is confirmed in writing. Full payment secures the appointment, and every invoice carries our full company details so you always know exactly who you are dealing with.
Brain-Wave Testing. Not Sweat & Heart Rate.
Why does the method matter for a Mallow case? Because a polygraph is hardest on anxious truth-tellers and easiest on calm, prepared subjects. P300 EEG looks at brain recognition rather than stress, which is a different question, and a fairer one to put to a nervous but honest person.
Traditional Polygraph
- Measures stress responses — not truth directly
- Affected by nerves, anger and stress
- Chart interpretation depends on the examiner
- Typically a 2-3 hour session
- Physiological sensors on the body
- Limited availability in Mallow
P300 EEG (What We Do)
- Measures brain recognition — not emotional state
- Involuntary recognition response
- Nerves do not fail an honest subject
- 60-90 minute appointment
- Waveform record with every report
- Examiner comes to you in Mallow

Relationship Trust
Private, discreet testing where trust in a relationship has broken down: disputed accounts of where someone was, messaging history disputes, or verifying a partner's statements before trust is rebuilt. Confidential venue, written report within 1 hour. Test both partners on the same visit for €949.
Family & Household
Theft in the home, inheritance disputes, adult children under suspicion, sibling disagreements, or accusations within blended families. Clear, objective answers without police involvement.
Business & Workplace
Specific-incident investigations with employee consent — missing stock, data leaks, suspected fraud, internal misconduct allegations. Test multiple suspects on one visit for significantly lower per-test cost.
False Accusations
If you've been accused of theft, dishonesty or misconduct at work or in your personal life, a passed P300 EEG test provides objective brain-wave evidence that you're telling the truth — far more robust than your word alone.
Pre-Relationship / New Partner
Past behaviour verification, dating-profile honesty, discrete checks before a serious commitment. Used quietly by many Mallow clients before getting engaged, buying property together, or introducing someone to children.
Second Opinion
Previously failed a polygraph elsewhere and want an independent P300 EEG test on the same facts? P300 measures brain recognition, not anxiety — so a nervous polygraph result doesn't predict a P300 result. Clean slate, different technology.
What Mallow Clients Say
★ 4.9 / 5 · based on 499 verified reviews across Deception Detection UK
Three-person business partner test came in cheaper than one polygraph each
"We needed all three founders tested independently after a money dispute. The grouped-visit pricing meant the whole exercise came in cheaper than three separate polygraphs would have been. Reports in our hands same day."
Cleared a teenage son of a drug accusation in the home
"We had wrongly accused our teenage son of something and needed to make it right with proof he could see and accept. The test cleared him cleanly. The conversation we had afterwards rebuilt trust in a way an apology alone could not."
Best technology I have seen in this space
"I work in tech and was sceptical until I saw the actual waveform data. The 8-channel EEG plus the methodology behind the analysis is genuinely impressive. Different league to anything else marketed as a lie detector."
Two-test couple visit handled with sensitivity
"Booked a two-test couple visit after months of arguments. The examiner separated us professionally, ran identical protocols on each, and gave us the results privately first before any joint conversation. Handled with care."
Definitive report stood up to scrutiny
"Used the report in a formal grievance hearing and the other side could not credibly challenge it. The waveform analysis and methodology section were strong enough that we did not need any expert witness in addition."

Common Questions From Mallow Clients
Tell us the dates that suit you and we check the diary for Mallow before you pay anything, so you never commit to a slot that does not work. If it is urgent, say so when you enquire and we will tell you straight away what is possible. The appointment itself is 60-90 minutes at your home or at a reserved suite at a Mallow town-centre or Springfort-side hotel, and the written report is handed over the same day.
Yes, and it is the most popular way to book. Each additional person on the same visit is €349, because the examiner is already with you and the venue is already covered. Two tests on the same day cost €949 rather than €1,198 as two single bookings; three cost €1,298. Five or more, get in touch for a group rate. Ideal for couples, business partners, family members in a dispute, or staff in a specific-incident investigation.
A traditional polygraph measures anxiety: breathing, heart rate and sweat. P300 EEG measures a brain response that appears when your brain recognises a detail you have seen or done before. It asks a different question, recognition rather than stress, so a nervous but honest person is not penalised for being nervous and a calm person is not credited for being calm. The published research on the method is summarised in the note at the foot of this page.
Strictly confidential. Tests take place in private booked venues. Reports are issued only to the paying client. We operate under GDPR and do not share, store or disclose any case information to third parties without written instruction. Nothing is filed with any authority, employer or family member unless you explicitly ask us to.
Very common reason for booking us. Traditional polygraph results can be distorted by nerves, medication, medical conditions, or poor question design — a genuinely truthful person can fail simply by being anxious. P300 EEG measures something different: brain recognition, not anxiety. A P300 test on the same underlying facts can provide a clear, independent second result.
Priced and charged in euro by card, so your bank makes no conversion. Enquiries can also be settled by SEPA, Wise or bank transfer. You can book and pay online, or ask a question first, agree a date, and pay once it is confirmed in writing. Full payment secures the appointment. Every quote and invoice carries our full company details: DadLink Technologies Limited, trading as Deception Detection UK, company number 16161444, with an Irish address in Longford and a UK office in Cheshire.
Tests are conducted in English. If the subject needs an Irish Gaelic or Polish interpreter, we can arrange one locally — just raise this at the enquiry stage so we can factor it into scheduling.
If you are in Belfast, Derry or elsewhere in Northern Ireland, you are covered by our UK service at £499 sterling, booked through the UK page rather than this one. Book directly through our UK booking page.
