Lie Detector Test Southampton & Hampshire
An Honest Answer, Once and For All
By the time people find this page, they are usually tired in a way sleep does not fix. A polygraph test finishes it: an answer with evidence, the same day. That includes proving your own innocence, not just testing someone else. Our suite sits beside Southampton Airport, two minutes from Parkway station, and we take on a limited number of examinations each week.
Single-Issue Testing for Accurate Results
Relationship Test
from £495You cannot unask the question once it has taken hold. What you can do is answer it properly. One issue, examined under controlled conditions on questions agreed with you beforehand, with a clear result inside 24 hours. However it comes out, the guessing ends there.
Couples Test
from £719Trust rarely breaks on one side only. A couples booking tests both partners on the same issue, separately, on the same day, and shares the results with you both. Many couples tell us the decision to book was the turning point in itself.
Pre-Employment Screening
from £549A CV tells you what someone wants you to know. For positions of real trust, cash handling, care work, site keys, a voluntary integrity screening tells you the rest. Hampshire employers use us before making offers they cannot easily take back.
Theft Investigation
from £549When money or stock disappears, everyone under the same roof becomes a suspect, and that is corrosive. Single issue testing removes people from suspicion one at a time until the picture is clear. The innocent tend to volunteer 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 £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
- 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
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 International House is conducted by an examiner trained to police standards in interviewing before qualifying in polygraph. That training brings patience, precision and a complete absence of judgement to situations that are often painful.
Because UK polygraph is unregulated, standards are a choice, and ours are the American Polygraph Association's. Validated techniques, annual continuing education and quality assured scoring. Nothing improvised, ever.
All examiners hold current Enhanced DBS checks.
Key Credentials
Following APA standards and best practices
Choosing a Legitimate Lie Detector Examiner
There is no governing body standing between you and a bad examiner. Anyone can buy the equipment and print a certificate. So before you book with anyone, us included, 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 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

- Computerised polygraph equipment (£8,000+ value)
- Single-issue testing for maximum accuracy

How It Works
Booking
Choose a service, pick a slot with live availability and pay online to confirm it. Preparation notes and exact directions to International House come straight to your inbox with your confirmation.
Pre-Test Interview
Testing starts with talking. You and your examiner spend the first hour agreeing the questions your examination will ask, worded so precisely that the result cannot be argued with.
The Examination
The examination itself runs to around 90 minutes. Sensors record breathing, cardiovascular activity and skin response while you answer the questions you have already agreed. Nothing is sprung on you.
Results
You leave knowing the preliminary result. Within 24 hours you receive the written report, with the recorded charts and the examiner's analysis set out in plain English.
