How a Bray P300 EEG Test Actually Runs
The practical detail clients ask about most: how do we get to Bray, where does the test happen, what does the day look like, what does the written report include. Everything below is the same whether you book a single test, a two-person visit, or a dedicated visit.
Travel to Bray
UK-qualified examiner inbound to Dublin Airport (DUB) — 1 hour via Dublin. Medical-grade 8-channel BrainBit EEG kit travels as cabin baggage in cushioned cases. Examiner arrives 2-3 hours before test start to allow for any travel delay.
Venue in Bray
reserved suite at a seafront or town-centre hotel. Corporate premises also accepted for workplace investigations. Venue is booked in advance and confirmed in writing once payment clears — strict confidentiality from the front desk.
The Bray Day
30-minute pre-test interview, 2-hour P300 EEG examination, 30-minute post-test debrief, 30-minute waveform analysis. Total venue time: 3.5 hours. Written report 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 Bray 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 held under UK GDPR equivalent standards.
Payment from Bray
EUR or GBP via international bank transfer, SEPA, Wise, or major credit card. Invoiced by DadLink Technologies Limited (UK). Full payment confirms the booking — this is how we hold your travel slot. No deposits on international bookings.
Brain-Wave Testing. Not Sweat & Heart Rate.
For Bray clients comparing options, here is the honest difference: polygraph machines measure how nervous you are. The P300 EEG measures whether your brain recognises a specific detail you claim not to recognise. One is an emotional signal that can be triggered by anything from a divorce to a tax deadline. The other is a cognitive signal that only fires if the information is already in your memory.
Traditional Polygraph
- Measures anxiety symptoms — not truth directly
- Heavily affected by nerves, anger, stress
- Countermeasures documented widely online
- Accuracy ~85-89% on single-issue tests
- Subjective chart interpretation
- Limited availability in Bray
P300 EEG (What We Do)
- Measures brain recognition — not emotional state
- Involuntary neural response — hard to suppress
- Countermeasures don't block P300 spikes
- 95% accuracy on guilty-knowledge protocols
- Objective waveform analysis
- UK-qualified examiner flown to Bray
Built for Bray's Most Common Cases
In Bray our caseload is dominated by relationship doubts, family inheritance disputes, internal theft investigations and false accusations. The common thread: a contested factual question that needs an answer that holds up. The categories below cover the bulk of what Bray clients bring us.In Bray our caseload is dominated by relationship doubts, family inheritance disputes, internal theft investigations and false accusations. The common thread: a contested factual question that needs an answer that holds up. The categories below cover the bulk of what clients bring us.
Relationship & Infidelity
Private, discreet testing for cheating allegations, emotional affairs, messaging history disputes, or to verify a partner's statements before trust is rebuilt. Confidential venue, written report within 1 hour. Test both partners on the same visit for just £998.
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 Bray 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 Bray Clients Say
★ 4.9 / 5 · based on 499 verified reviews across Deception Detection UK
Clear written report inside the hour as promised
"I had been told by previous providers that reports take days. The examiner handed me a bound written report before I left the venue. That alone made the difference for what I needed it for."
Cleared my name after a workplace theft accusation
"I was wrongly accused of taking cash from the till at work. The P300 test cleared me categorically and my employer reinstated me with backpay. The written report was the difference between losing my career and keeping it."
Two suspects tested on the same visit saved real money
"Our small business had a stock-shrinkage problem narrowed to two warehouse staff. Testing both on the same day cost half what two separate trips would have. One passed cleanly, one did not — case closed."
Polygraph elsewhere was inconclusive — P300 was definitive
"Took a polygraph in London first and the result came back inconclusive after two attempts. Booked a P300 EEG with these guys, got a clear definitive verdict in a single session. Different technology, different result."
Pre-engagement honesty check before a big decision
"My partner and I both took the test before getting engaged. It sounds extreme but for us it settled some lingering doubts cleanly and we are now happily engaged. The two-person rate made it doable."

Common Questions From Bray Clients
For Bray, the closest international entry point is Dublin Airport (DUB) — that is the route we take. From the UK side it is 1 hour via Dublin. The examiner books the inbound flight to arrive 2-3 hours before the test, allows for any delay, then heads straight to the booked venue (reserved suite at a seafront or town-centre hotel) once you confirm you are en route.
Yes — and it's our most popular option in Bray. Each additional person on the same visit is only £299, because our flights and venue costs are already covered. Two tests on the same day costs £998 instead of £1,398 if booked separately. Three tests for £1,297. 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.
Traditional polygraph measures anxiety — breathing, heart rate, sweat. P300 EEG measures a specific brain-wave that fires involuntarily when your brain recognises a detail you've seen or done before. It's measurably more accurate (95% vs ~85%), not defeated by common countermeasures, and not distorted by nervousness. Crucially, a guilty person's brain still recognises the crime even if they're calm — and an innocent person's brain won't recognise details they've never seen, no matter how anxious they are.
Strictly confidential. Tests take place in private booked venues. Reports are issued only to the paying client. We operate under UK GDPR standards (equivalent to Irish 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.
We accept EUR or GBP payment via international bank transfer, SEPA, Wise, or major credit cards. All invoices are issued by DadLink Technologies Limited (UK). Full payment is required to confirm the booking — we don't take deposits on international bookings. This protects both parties and secures examiner travel arrangements.
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're in Belfast, Derry or elsewhere in Northern Ireland, you're part of our UK service — which is considerably cheaper than the Ireland (Republic) rates shown here, as no flight is needed. Book directly through our UK booking page from £699.
