    Lie Detector Test Exeter & Devon

    Certainty, This Side of Bristol

    An unanswered question does not care how far from anywhere you live. One examination at our Exeter or Taunton office settles it: questions agreed with you beforehand, a controlled test, and the answer in hand before you drive home. Many clients come to prove their own honesty rather than test anyone else's. Both offices sit just off the M5 with parking, and we take on a limited number of examinations each week.

    Single-Issue Testing for Accurate Results

    Relationship Test

    from £419

    Doubt about a partner does not care how far you are from a big city. One issue, examined properly at our Exeter or Taunton office, produces a clear result within 24 hours. Plenty of clients tell us the drive home afterwards was the calmest hour they had had in months.

    Couples Test

    from £695

    When the mistrust runs both ways, a couples booking tests each of you separately on the same day, at the same office, on the same agreed issue. You both leave with the results and it costs less than two single examinations.

    Pre-Employment Screening

    from £549

    For West Country employers, one dishonest hire in a small team does damage a big company would absorb. A voluntary integrity screening before the offer letter adds certainty that references cannot, for roles with cash, keys or vulnerable people.

    Theft Investigation

    from £449

    When something disappears from a home, a farm or a business, suspicion spreads faster than facts. Single issue testing clears the innocent one by one and shows where the problem really lies. Often the person keenest to be tested is the one wrongly accused.

    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 £125 to £150 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, every week

    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 Exeter

    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.

    Examinations at both our offices are conducted by examiners trained to police standards in interviewing before qualifying in polygraph. Hundreds of private and corporate examinations later, they bring the same patience and precision to every client in Devon and Somerset.

    The South West has fewer polygraph operators than the big cities, which cuts both ways: less choice, and less scrutiny. We hold ourselves to the American Polygraph Association's standards precisely because nobody else makes us: validated techniques, annual training and quality assured scoring.

    Every examiner holds a current Enhanced DBS check.

    Choosing a Legitimate Lie Detector Examiner

    With no UK regulator, polygraph quality is entirely down to the examiner you choose, and in the South West the choice is thin enough that some firms count on you not checking. Check anyway, us included:

    Red Flags to Avoid

    • No physical charts or data provided with results
    • Home tests with no screening of the room or conditions
    • Prices significantly below £350
    • Same-day results promised before the test
    • 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 at Exeter Business Park and Taunton, both with onsite parking
    • Computerised polygraph equipment (£8,000+ value)
    • 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 your report. Heart rate, blood pressure, breathing and skin response, the raw traces your result was scored from. An examiner who will not release them is hiding either the equipment or the training.

    Where our clients travel from

    Every examination takes place at one of our two offices, Exeter Business Park or Blackbrook in Taunton. These are the towns our clients most often travel from, and how they get here.

    How It Works

    1

    Booking

    Book online in minutes: choose a service, pick either the Exeter or Taunton office, select a slot with live availability and pay to confirm. Preparation notes and full directions arrive immediately with your confirmation.

    2

    Pre-Test Interview

    Nothing is recorded until the questions are right. Your examiner spends the first 45 to 60 minutes with you agreeing exactly what the examination will test, worded so the result cannot be argued with afterwards.

    3

    The Examination

    The recorded examination takes around 90 minutes. Sensors monitor breathing, cardiovascular activity and skin response while you answer a short set of yes or no questions you have already seen and approved.

    4

    Results

    Your examiner explains the preliminary result before you leave the office, whichever office that is. The full written report with the recorded charts reaches you within 24 hours.

    Frequently Asked Questions

    Get answers to the most common questions about polygraph testing

    Not even slightly. In smaller communities the wondering is worse, because the question follows you into every room. Booking a test is not dramatic; living for months without an answer is. One appointment at Exeter or Taunton retires the question for good, and nobody around you need ever know it happened.

    Statements show a short LPI reference from our parent company. Polygraph, lie detector, Exeter: none of those words appear on the transaction, so even a shared account reveals nothing.

    We cannot and will not test anyone against their will; free written consent is checked at the office before a single question is recorded. But watch what the offer does. In our experience the innocent tend to say yes quickly, and a refusal, made knowing the test is fair, is an answer of a different kind.

    Between 90 and 98 percent decision accuracy when conducted properly: an APA trained examiner, modern computerised equipment, a controlled office and validated question techniques. All four apply at both our offices, and all four are worth checking with anyone else you consider.

    No. Scoring is based on the differences between your responses to different question types, not on how calm you are overall. Almost everyone who sits in the chair is nervous, and honest examinees pass nervous every week.

    A single issue test is £419 at either office, booked and paid online with nothing added afterwards. Couples tests are £695, theft and pre-employment tests £449. Every price includes the pre-test interview, the examination and the full written report with charts.

    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 — 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.
