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 2 Kingdom Street, Paddington, London W2 6BD

Getting to the London – Paddington 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 London – Paddington — What to Know
The Paddington suite at 2 Kingdom Street sits in Paddington Central, the canal-side office estate directly behind Paddington station. The station is the reason this office exists: the Heathrow Express arrives fifteen minutes from the airport, the Elizabeth line runs east–west across the capital, and Great Western services feed in from Reading, Oxford, Bristol, South Wales and the West Country — so a client can leave Cardiff or Cornwall in the morning, be examined by early afternoon, and be home for dinner.
That reach defines the clientele. Alongside West London locals from Maida Vale, Bayswater and Notting Hill — whose cases run the familiar range of infidelity, family money disputes and pre-marital questions — Paddington handles a constant stream of long-distance and international clients. Some fly in via Heathrow purely for the examination; others are West Country and Welsh clients who prefer London's anonymity to a test nearer home. The estate's steady office footfall along the canal makes every arrival unremarkable.
A single-issue examination at Paddington is £595; couples travelling in together are examined in one visit at £895. A £150 deposit secures the appointment, with the balance paid on the day. Because so many clients here are working around trains and flights, we confirm timings precisely at booking and recommend a minimum one-hour buffer between your arrival into Paddington and the start of your session.
