Lie Detector Test Swindon & Wiltshire
The Truth, Just Off the M4
By the time most people reach this page, the not knowing has gone on far too long. A polygraph test ends it: an answer backed by evidence, on the day. That includes clearing your own name, not only testing someone else. Our Swindon office is at Windmill Hill Business Park, just off junction 16 of the M4, with parking onsite.
Single-Issue Testing for Accurate Results
Relationship Test
from £449A suspicion does not fade because you decide to ignore it. It waits. A relationship test puts one issue under controlled conditions, on questions agreed with you before anything is recorded, and gives you a result with the charts to back it. Whichever way it falls, you stop guessing.
Couples Test
from £695When both of you have something to prove, test both of you. A couples booking examines each partner separately on the same issue, on the same day, and shares the results with you both. Agreeing to book is often the first honest conversation in months.
Pre-Employment Screening
from £549References confirm dates. They do not confirm character. For roles that involve cash, keys, vulnerable people or confidential data, a voluntary integrity screening before the offer goes out tells you what a CV cannot. It is far simpler than unpicking a bad hire later.
Theft Investigation
from £499Money or stock goes missing and suddenly a whole team is under a cloud. Single issue testing clears people one at a time, on their own agreed questions, so suspicion stops spreading. Those with nothing to hide usually ask to go first.
Secure any test today with a £149 deposit
Book the date now and the balance is collected automatically two days before your appointment, so there is nothing to remember and nothing to pay on the day. Prefer to settle it upfront? Pay in full and you can spread the cost with Klarna at checkout.
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 the dates you would prefer
- 3Wait for a call back, typically several days
- 4An examiner is found and a room hired for the day
- See the real 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 your payment goes through
- Our own office, our own examiners
A deposit with us is not a place in a queue. It confirms a real appointment at a real time, instantly. As far as we know, no other UK polygraph service offers instant confirmed booking or takes Klarna.
Evenings, weekends, or unable to travel?
If you require an evening or weekend test, our home visit service brings the same examiners, the same instruments and the same instant online booking to your own home, 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 Swindon office is run by an examiner trained to police standards in interviewing before qualifying in polygraph. That background shows in the room: patient, exact, and without a trace of judgement about why you are there.
Polygraph is unregulated in the UK, so the standard an examiner works to is their own choice. Ours is the American Polygraph Association's: validated question techniques, continuing education every year and scoring that is checked rather than guessed.
Swindon Polygraph Services is part of LocalPI, established in 2019, with more than 2,000 examinations completed across the group. All examiners hold current Enhanced DBS checks. Same methods, same instruments, same report, wherever you are tested.

Choosing a Legitimate Lie Detector Examiner
Nobody licenses polygraph examiners in the UK. The equipment can be bought online and the certificate printed at home. So before booking with anyone, including us, look for these warning signs:
Red Flags to Avoid
- ✕No charts or recorded data supplied with the result
- ✕Testing in the client's home with no check on the room
- ✕A price too low to pay for proper training and equipment
- ✕A result hinted at before the test has been run
- ✕Several unrelated issues squeezed into one session
- ✕No proper pre-test interview
- ✕Reluctance to explain how the test works
- ✕Training and experience you cannot verify
What We Provide
- Full written report with the physiological charts
- A private, solid-walled meeting room at Windmill Hill Business Park, Swindon
- Computerised polygraph instruments
- Single-issue testing for the most accurate result
- American Polygraph Association protocols
- Every step explained before it happens
- Training and standards you can check
- An unhurried examination, never a conveyor belt
Your charts arrive with your report. Breathing, heart rate, blood pressure and skin response: the actual traces your result was scored from. A provider who cannot show you charts either has no proper instrument or does not know how to read one.

How It Works
Booking
Pick a service, choose a slot from live availability and pay online. Your confirmation arrives straight away with preparation notes, the full address at Windmill Hill Business Park and where to park.
Pre-Test Interview
The appointment opens with a conversation, not a sensor. You and the examiner go through the issue and settle the exact wording of every question, so that nothing on the test is new to you and nothing in the result can be argued away.
The Examination
The whole appointment takes around 90 minutes, so allow two hours. In the examination itself, sensors record breathing, cardiovascular activity and skin response while you answer the questions already agreed. That is all they do.
Results
The examiner tells you the preliminary result before you leave. The written report follows within 24 hours, with the recorded charts and the analysis explained in plain English.
