Lie Detector Test Slough & East Berkshire
Know for Certain, This Week
People who reach this page have usually been turning the same question over for a long time. A polygraph test ends it: an answer backed by evidence, with the preliminary result before you leave. That includes clearing your own name, not only testing someone else. Our office is on the Bath Road in Slough, just off junction 6 of the M4, with parking onsite, and we take on a limited number of examinations each week.
Single-Issue Testing for Accurate Results
Relationship Test
from £449A suspicion does not fade because you stop talking about it. A relationship test takes the one issue that matters, examines it under controlled conditions on questions agreed with you beforehand, and gives you a clear result inside 24 hours. Whichever way it falls, the guessing stops.
Couples Test
from £695When trust has gone on both sides, one test rarely settles it. A couples booking examines both partners on the same issue, separately, on the same day, and shares the results with you both. Agreeing to book together is often the first thing you have agreed on in months.
Pre-Employment Screening
from £549References confirm what a candidate has chosen to tell you. For roles built on trust, cash, keys, vulnerable people, confidential data, a voluntary integrity screening fills in the rest before the contract is signed. Employers use it when an offer would be costly to withdraw.
Theft Investigation
from £499Missing stock or money puts everyone in the building under suspicion, and that does more damage than the loss itself. Single issue testing clears people one at a time, on the same agreed questions, until the picture is plain. Those with nothing to hide usually ask to go first.

Booked means booked
There are two ways to book a lie detector test in the UK. They are not the same.
Most polygraph websites
- 1Pay a deposit, often non-refundable
- 2Fill in a form with your preferred dates
- 3Wait for a call, typically 3 to 5 days out
- 4Card only, an examiner assigned, a room hired for the day
- See the actual calendar with real free slots
- Pay in full, or secure eligible dates with a deposit
- Spread the cost with Klarna at checkout
- Confirmed the moment payment completes
- Our own offices, our own examiners
A deposit here is not a place in a queue. It confirms a real appointment, instantly. To our knowledge, no other UK polygraph service offers instant confirmed booking or takes Klarna.
Evenings, weekends, or unable to travel?
Our home visit service brings the same examiners, the same instruments and the same instant booking to your own front room, seven days a week with the last examination starting at 8pm. Enter your postcode and see real visit times for your address.
Your Examiner
A note from your examiners: you will not find our names or faces on this website, and that is deliberate. The nature of this work means examiners here stay anonymous, and the same discretion that protects us is what protects every client we test. What we can tell you is that we are trained to police standards in interviewing, and that the words clients use most about their examinations are rarely the ones they expected to use.
"You are very calming." "Thank you so much for putting me at ease." Said to us by recent clients, during and after their examinations.
Every examination at our Bath Road office is conducted by an examiner trained to police standards in interviewing before qualifying in polygraph. That background shows in the room: patience, exact wording, and no judgement about why you are there.
Polygraph is unregulated in the UK, so the standards an examiner works to are a matter of choice. Ours are the American Polygraph Association's: validated techniques, annual continuing education and quality assured scoring. Nothing is improvised.
All examiners hold current Enhanced DBS checks.
Key Credentials
Following APA standards and best practices
Choosing a Legitimate Lie Detector Examiner
Nobody licenses polygraph examiners in the UK. The equipment can be bought online and a certificate can be printed at home. So before booking with anyone, including us, check for these things:
Red Flags to Avoid
- ✕No physical charts or data provided with results
- ✕Home tests with no screening of the room or conditions
- ✕Prices far below the going rate
- ✕A result promised before the test has been run
- ✕Multiple issues tested in one session
- ✕No formal pre-test interview
- ✕Unwillingness to explain the process
- ✕No verifiable training or experience
What We Provide
- Comprehensive report with physiological charts
- Private, solid-walled testing room at our Bath Road office, Slough
- Computerised polygraph equipment
- Single-issue testing for maximum accuracy
- APA testing protocols followed
- Full transparency about the process
- Verifiable qualifications and experience
- Professional, unhurried examination
Your charts come to you with the report. Heart rate, blood pressure, breathing and skin response, the actual traces your result was scored from. If a provider cannot show you charts, ask what the result was scored from.

How It Works
Booking
Choose a service, pick a slot from the live calendar and pay online to confirm it. Preparation notes and exact directions to our Bath Road office, including where to park, arrive by email with your confirmation.
Pre-Test Interview
The appointment begins with a conversation, not a machine. You and your examiner agree the questions your test will ask and settle the exact wording, so that nothing in the result can be argued away afterwards.
The Examination
The whole appointment takes around 90 minutes, so allow two hours. During the examination itself, sensors record your breathing, cardiovascular activity and skin response while you answer the questions already agreed. There are no surprise questions.
Results
You leave knowing the preliminary result. Within 24 hours the written report follows by email, with the recorded charts and the examiner's analysis explained in plain English.
