    Lie Detector Test Reading & Berkshire

    Clear Answers, Close to Home

    Living with an unanswered question wears people down more than any answer ever does. A polygraph test at our Forbury Square or Theale office ends it: questions agreed with you beforehand, a controlled examination, a definitive result the same day. Whether the truth you need is someone else's or your own, our examiners, trained to police standards in interviewing, are a short walk from Reading station or just off the M4 at Theale, and we take on a limited number of examinations each week.

    Two offices: a short walk from Reading station at Forbury Square, or onsite parking at Theale off M4 junction 12.

    Single-Issue Testing for Accurate Results

    Relationship Test

    from £419

    Suspicion has a way of taking over everything. A single issue test, conducted privately at either of our Reading offices, gives you the answer that matters within 24 hours. Whatever the result shows, you will finally know where you stand.

    Couples Test

    from £695

    When neither partner fully trusts the other any more, testing together can reset the conversation. You are each examined separately on the same day, on the same issue, and you both receive the results. It also costs less than two individual tests.

    Pre-Employment Screening

    from £549

    References rarely tell you who someone really is. For roles involving money, vulnerable people or sensitive information, a voluntary screening test gives Thames Valley employers an extra layer of certainty before the contract is signed.

    Theft Investigation

    from £549

    Something has gone missing and suspicion is spreading through the house or the workplace. A focused polygraph test clears the innocent quickly and shows you where to look next. In our experience it is often the wrongly accused who want the test most.

    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
    Booking here
    • 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 fee to join 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

    Professional polygraph and lie detector testing facility in Reading with Stoelting CPS examination equipment

    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.

    The examiners who test at our Reading offices were trained to police standards in interviewing before qualifying in polygraph. They have conducted hundreds of private and corporate examinations, and they treat every client with the same steady, unhurried professionalism.

    This is an unregulated industry, which makes voluntary standards the only meaningful ones. Our examiners follow American Polygraph Association protocols, complete continuing training every year and use only validated questioning techniques.

    Each examiner is Enhanced DBS checked as a matter of course.

    Choosing a Legitimate Lie Detector Examiner

    No licence is required to call yourself a polygraph examiner in the UK. None. That means the checking falls to the person booking the test. Here is what separates a professional service from a cheap imitation:

    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
    • Permanent offices in central Reading and at Theale
    • 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 report always includes the physiological charts recorded during your examination. Heart rate, blood pressure, breathing and skin response: that raw data is the basis of your result and it belongs with you. Treat any examiner who keeps the charts to themselves with suspicion.

    Where our clients travel from

    Every examination takes place at one of our two Reading offices: Forbury Square in the town centre, a short walk from the station, or Theale, just off junction 12 of the M4. These are the places our clients most often travel from, and how they get here.

    How It Works

    1

    Booking

    Book online in a few minutes: pick a service, choose a time with live availability and pay to confirm. Preparation notes arrive by email straight away. Choose between our Forbury Square office in the town centre, a short walk from Reading station, and our Theale office just off junction 12 of the M4, with paid parking onsite.

    2

    Pre-Test Interview

    The first part of the appointment is spent talking, not testing. You and your examiner agree the precise questions the examination will address, because well worded questions are the difference between a useful result and a wasted afternoon.

    3

    The Examination

    The whole appointment takes around 90 minutes, so allow two hours. During the examination itself, sensors track your breathing, cardiovascular activity and skin response while you answer a short set of yes or no questions you have already agreed.

    4

    Results

    You hear the preliminary outcome before you leave the office. The complete written report, charts and analysis included, reaches you within 24 hours.

    Frequently Asked Questions

    Get answers to the most common questions about polygraph testing

    Looking is not overreacting. People do not research polygraph tests idly; by the time you are here, the question has usually been circling for weeks. Booking does not declare anyone guilty and it does not end a relationship. It ends the circling. In our experience, those who leave to think it over rarely return, and not because things improved.

    It appears as a brief LPI reference, our parent company. Nothing on the statement says polygraph or Reading Polygraph Services, so even someone reading the account line by line learns nothing.

    Nobody can be compelled, and consent given under pressure invalidates the result anyway, so we simply will not test a reluctant examinee. The offer itself does useful work though. A partner with nothing to hide usually says yes. A partner who refuses outright has given you something to weigh, gently but honestly.

    Under proper conditions a single issue test achieves decision accuracy in the region of 90 to 98 percent. The variables that decide where in that range you land are all checkable in advance: examiner training, equipment, venue and question technique. Book an APA-trained examiner in a controlled office and you are at the strong end of it.

    It cannot. Scoring works by comparing your responses between different types of question, not by measuring how calm you are overall. Nervous and honest reads as honest. If anxiety could fail people, nobody would ever pass, because nearly everyone arrives nervous.

    A single issue examination at either of our Reading offices is £419, booked and paid online with nothing extra to pay afterwards. That includes the pre-test interview, the test itself and a full written report with charts inside 24 hours.

    No. If your appointment is more than three days away you can secure it with a £149 deposit, and the balance is collected automatically from the same card two days before your test. Nothing to remember, nothing to pay on the day. The deposit is non-refundable, because it protects the appointment we hold exclusively for you, and if you would rather settle everything upfront you can pay in full, including in three instalments with Klarna.
