Liverpool Testing Services
Lie detection testing across Liverpool and Merseyside using advanced P300 EEG. We measure brain responses directly to known stimuli, producing court-ready evidence with industry-leading accuracy.
How P300 EEG Lie Detection Works
Event-Related Potential (ERP): We present an “oddball” sequence of images/words. When the subject recognises a relevant detail, the brain emits a P300 spike (~300ms latency) that we record via EEG.
Direct Neural Signal: Multiple scalp electrodes capture millisecond-level activity. Because P300 is involuntary, it cannot be reliably suppressed or “beaten”.
Artifact Rejection & Averaging: We remove muscle/blink noise and average signals across trials to isolate the true P300 response with high signal-to-noise ratio.
95% Accuracy: Structured stimuli, strict question design, and validated analysis pipelines deliver consistent, court-presentable results.
Quality Controls: Baseline runs, control items, and examiner cross-checks verify cooperation and data integrity.
Efficient Sessions: Typical appointments take 45–90 minutes including setup, testing, and results review.

P300 vs Polygraph Lie Detector Tests in Liverpool
P300 EEG Technology
Direct measurement of brain activity in response to relevant stimuli. Strong scientific foundation and robust against countermeasures.
- ✓ Measures brain activity directly
- ✓ Stronger legal standing in Liverpool courts
- ✓ Faster testing (45–90 minutes)
- ✓ Resistant to manipulation
- ✓ Expert witness testimony included
Traditional Polygraph (Comparison)
Measures physiological responses (heart rate, blood pressure, skin conductance). Vulnerable to countermeasures.
- ✓ Established legal precedent
- ⚠ Can be influenced by countermeasures
- ⏱ Longer sessions (2–3 hours)
- £799 typical cost in Liverpool
Note: We do not offer polygraph testing in Liverpool. Polygraph details are provided for comparison only.

Technology & Accuracy
P300 EEG measures direct neural recognition (event-related potentials), while polygraph measures indirect physiological changes. P300 offers stronger scientific grounding and higher accuracy.
| Feature | P300 EEG | Polygraph (Comparison) |
|---|---|---|
| Accuracy | 95% | 65–75% |
| Duration | 45–90 minutes | 2–3 hours |
| Manipulation | Resistant | Vulnerable |
| Liverpool pricing | £499 | £799 |
P300 EEG consistently delivers around 95% accuracy with proper stimuli design and cooperation. Accuracy benefits from:
- Validated ERP protocols and controls
- Multiple-trial averaging and artifact rejection
- Clear, factual yes/no question design
- Certified examiners and QC checks
P300 measures involuntary neural recognition. Attempts to manipulate the signal are detected through control items, consistency checks, and noise screening. This makes countermeasures ineffective compared to polygraph.
Test Process & Preparation
- P300 EEG: 45–90 minutes (setup, testing, results)
- Complex/legal cases: May require additional time
- Sleep 7–8 hours the night before
- No alcohol for 24 hours
- Limit caffeine 4 hours before
- Eat normally (avoid heavy meals)
- Continue prescribed medications
- Arrive early (traffic/parking)
- Bring photo ID and any case documents
