Arrival & Check-In
What happens
You check in at the business centre reception under the name on your booking — there is no polygraph signage anywhere, for your privacy. Reception shows you to a private waiting area; your examiner meets you there and verifies your photo ID before anything begins.
Your part
- Bring a valid government photo ID and your confirmation
- Arrive rested — not rushed, not caffeinated
- A support person may wait in reception
Pre-Test Interview
What happens
Your examiner explains the entire procedure and the instruments, completes your consent paperwork, and conducts a psychophysiological suitability assessment — covering health, medication, and sleep. Then, together, you review and agree the exact wording of every test question. Nothing asked during the examination will be a surprise.
Your part
- Be open about medications and health conditions
- Raise anything you want asked — this is the moment
- Ask questions until you are fully comfortable
The Examination
What happens
Sensors are placed on your upper body and connected to a government-grade computerised instrument. You answer the agreed yes-or-no questions while four physiological channels are recorded. Each question is repeated a minimum of 3 times across multiple charts — a single reaction never decides a result.
What the instrument records
- Cardiovascular activity — heart rate & blood pressure
- Electrodermal activity — skin conductivity
- Thoracic & abdominal respiration
- Movement & timing, chart by chart
Analysis & Verbal Result
What happens
The examiner scores your charts using standardised numerical scoring, explains what the data shows, and discusses the preliminary outcome with you in the post-test review. You leave knowing your result — not waiting for a letter.
Your part
- Ask anything about how the result was reached
- Discuss next steps if the matter is ongoing
Your Written Report
What it contains
- The methodology and technique used
- Every question asked, verbatim
- The recorded physiological data
- The examiner’s professional conclusions
Confidentiality
Results are shared only with you unless you authorise otherwise in writing. Reports are suitable for attorneys and, where your matter requires it, prepared with legal proceedings in mind.
- Pre-test consultation (30–45 min) — all questions reviewed and agreed before the test begins
- Full polygraph examination — questions repeated minimum 3 times for accuracy using digital instruments
- Post-test review — examiner discusses preliminary findings with you
- Detailed written report — methodology, question-by-question results, physiological data, and professional conclusions
- Private testing venue — discreet, climate-controlled suite at Waldron Hythe, Dartford DA1 1UN

Getting to the Dartford Office
Travelling Far? Arrive the Night Before
If your journey is more than about two hours, we strongly recommend travelling the evening before and staying near the office. A full night’s sleep is not just comfort — fatigue measurably affects the physiological responses the polygraph records, and a rested examinee produces a cleaner, more reliable chart. Book a morning appointment, sleep 7–8 hours, have a light breakfast, and arrive unhurried.
How to Prepare
- Get a full night’s sleep — fatigue affects physiological responses and concentration
- Eat a light meal beforehand; the appointment lasts up to 2 hours
- Avoid excessive caffeine, energy drinks, and nicotine on the day
- Take prescribed medication as normal and tell your examiner what you take
- Wear comfortable clothing — sensors are placed on your upper body
What to Bring
- A valid government-issued photo ID — your identity is verified before testing
- Your booking confirmation
- Any relevant documents or case notes for your examiner
- A written list of the questions or concerns you want addressed
- Glasses or hearing aids, if you use them
What Not to Do
- × Do not drink alcohol or take non-prescribed drugs in the 24 hours before your test
- × Do not stop prescribed medication — changing your routine skews your baseline
- × Do not arrive sleep-deprived, unwell, or rushed
- × Do not attempt countermeasures — they are detectable and can invalidate your result
- × Do not bring children into the session; an adult support person may wait in reception
When Testing Cannot Go Ahead
- × If you are under the influence of alcohol or non-prescribed drugs on the day
- × If you are severely ill, exhausted, or in significant pain
- × If a medical condition makes testing unsuitable without physician clearance
- × If you are under 18, or required consent is missing
- × If the examiner’s case review finds the matter unsuitable — your £225 deposit is refunded in full

Why This Matters — What a Professional Examiner Looks Like
Polygraph Testing in Dartford — What to Know
Dartford's position at the Kent end of the crossing gives our Waldron Hythe office an unusually wide draw: clients come from Bexley and south-east London on one side and Gravesham and Medway on the other, with a steady trickle from Essex over the bridge. For many, Dartford is deliberately neutral ground — close enough to reach easily, far enough that nobody familiar will see them.
Relationship cases lead here, as they do across Kent, and the town's commuter character is part of the story. Long London working days and shift patterns at the Bluewater retail complex or the industrial estates along the river create the absences that let suspicion grow. A single-issue examination in Dartford is £595, and couples frequently book a joint appointment so both partners address the same question on the same day.
The second strand is commercial. Logistics and warehousing dominate local employment, and haulage operators bring us cargo-theft and fuel-card allegations they would rather resolve internally than report. All such tests are voluntary, with the employee's written consent.
Family-court-adjacent work rounds out the picture: parents facing allegations in private law proceedings sometimes sit a test to support their account, knowing the result informs negotiations even though English courts will not admit it as evidence.

Beware of Unqualified Examiners

Unfortunately, unqualified individuals operating without accreditation continue to damage the industry’s reputation and deliver unreliable results. Always verify your examiner graduated from an APA-approved school and uses validated testing protocols.
