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 local 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)
- £499 typical cost
Note: We do not offer polygraph testing in Allerton. 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 |
| Allerton 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
