The Polygraph Examiners Union of Ukraine (SPU) carries out private lie detector tests across Greece — Athens, Thessaloniki, Patras, Crete and the islands. Sessions are conducted in English, with the preliminary conclusion given the same day.
In short: a private lie detector test in Greece costs €365 for a standard single-topic examination, takes 1.5–2.5 hours and delivers 95–98% accuracy. The examiner travels to Athens, Thessaloniki, Patras, Larissa, Heraklion and the island resorts, or you can take the test at an address of your choosing. A verbal conclusion follows immediately after the session; the signed written report arrives within 3–5 business days and is included in the price. Testing is voluntary and requires written consent, and SPU examiners are listed in the official Register of Polygraph Examiners of Ukraine, and our local partner examiners work to the same protocols.
Greece runs on two calendars. From spring to autumn the country fills with seasonal staff, short contracts and cash businesses; in winter the same towns empty out and the season’s accounts finally get looked at. Add family firms where the till and the family purse are the same thing, and long absences at sea, and you get a very specific kind of question — concrete, factual and impossible to settle by argument.
That is what a lie detector test is for. It will not repair a relationship or replace a lawyer, but it converts a suspicion that has been running for months into one documented answer. Here is what people ask us about most often.
Long absences, an unexplained trip, a story that has been retold three different ways.
Infidelity test →
Voluntary screening for staff who handle cash, keys and guests' belongings during the season.
Personnel screening →
Loans between relatives, an inheritance split by agreement, a business share nobody wrote down.
Borrower assessment →
A psychophysiological examination when your name is questioned and nothing can be shown either way.
Forensic testing →
Housekeepers, carers and property managers who hold keys to a house that stands empty half the year.
Household staff vetting →
Substances, money disappearing at home, a circle of friends that changed over one summer.
Teen testing →Long absences are ordinary here rather than exceptional. A crew member is away for months at a time; a season on an island keeps one half of a couple on the other side of the water until October; a family hotel runs on staff who arrive in May and leave in September. None of that creates dishonesty, but all of it creates gaps — weeks that are hard to account for afterwards.
By the time people book an examination they usually know exactly which question they need answered, and our job is to answer that one properly rather than to audit somebody’s life. Testing runs only on informed written consent, never behind a partner’s back, and any question can be withdrawn without an explanation.
The second recurring theme is money inside families: an inheritance divided by handshake, a loan to a cousin, a share in a small hotel agreed at a kitchen table. When such an arrangement breaks down there is rarely a document to point at, and a court case would cost more than the sum in dispute and end the relationship for good.
A lie detector records several physiological channels at once — breathing, cardiovascular activity, blood pressure and electrodermal response. Concealment produces involuntary shifts in those channels that cannot be switched off deliberately.
SPU examiners follow the standardised CQT and CIT protocols on professional equipment. Accuracy under protocol is 95–98%.
Half the work happens here: we narrow a vague worry down to questions that can actually be tested, and you approve each wording before anything is recorded.
The consent form is signed, then four sensors go on — chest, arm, fingers. Nothing is injected, nothing hurts, and everything can be taken off in seconds.
The agreed questions are put in a fixed order and repeated in several charts. Repetition is what turns a one-off reaction into evidence or into noise.
You hear where the charts point before you leave the room. The signed document, with the methodology and the question list attached, follows in 3–5 business days.
A lie detector does not read minds. It compares reactions to relevant questions with reactions to control questions, across four channels, and looks for a stable difference between the two. Those responses are involuntary, which is precisely why they are informative: the body answers before the person has finished choosing their words.
No conclusion rests on a single spike. What counts is a pattern that repeats across several presentations — that is what separates ordinary nervousness, which lifts everything at once, from a concealment reaction, which is selective. Much of the outcome is decided earlier, in how the questions are built; our editorial team has published a breakdown of the questions asked during a polygraph examination, including those that may not be asked at all.
A lie detector test answers factual questions about events: whether money was handed over, whether a meeting took place, whether something was concealed at hiring. It does not measure feelings, forecast behaviour or decide who behaved better in a quarrel. Anyone promising otherwise is describing something else.
This is why the interview matters more than the equipment. A fair share of enquiries end with us saying that two or three precisely worded questions will do the work of fifteen vague ones — or that an examination is the wrong instrument here entirely. That conversation is free and happens before any booking.
The figure below is the whole cost of a standard case — not a rate per hour that grows while you sit in the chair. The consultation beforehand is free, and the written conclusion is part of the price rather than an upsell at the end.
| Format | What it covers | Price, EUR |
|---|---|---|
| Standard polygraph examination | One subject, one topic; 1.5–2.5 hours including the interview; written report included | €365 |
| Online-format examination | When the parties are in different countries and meeting in person is not realistic | €175 |
| Testing in a foreign language | Surcharge outside our working languages — English, Spanish, Russian and Ukrainian are included | +€80 |
| Multi-topic or corporate examination | Several respondents, an internal investigation, urgent scheduling | Quoted individually |
The standard price covers most private requests — resolving a family conflict, a check before marriage, establishing who took what, an examination at a lawyer's request and a visit by the examiner to your address. Company formats such as an internal investigation or a scheduled staff check are costed per case, since the workload depends on the number of participants.
Treat these as reference figures: what you pay is fixed during the free consultation, once we know how many topics and how many people are involved and where the session will be held.
| Criterion | SPU | Independent examiner |
|---|---|---|
| Who the examiner answers to | The union and its standards board | Nobody but themselves |
| Certification you can check | ✓ SPU certification and protocols | Rarely verifiable |
| Protocol | CQT and CIT, applied the same way every time | Whatever the examiner prefers |
| Second opinion on the charts | Available on request | Not possible |
| Paperwork | Consent form and reasoned conclusion as standard | Often a verbal answer only |
Greek cases are handled by local certified partner examiners of the Polygraph Examiners Union of Ukraine. Which of them takes your case depends on the subject: corporate and legal work and delicate family matters call for different experience.
Both work to SPU methodology and under the union's quality control: the question list is agreed in advance, the charts can be re-read by a second examiner, and the conclusion is issued on a union form. We name the examiner assigned to you when the appointment is confirmed.
Tell us what happened and we will say honestly whether a test can answer it. The consultation is free.
Get a consultationThe owners closed a busy summer with takings that did not match the bookings. Six seasonal employees had handled cash at some point, most of them leaving the island within weeks. Four agreed to a voluntary lie detector test before departure. One session explained the shortfall, the others left with their reputations intact, and the family avoided accusing a whole team on the strength of a spreadsheet.
A woman in Piraeus had spent four years married to a man who worked long contracts at sea. Every homecoming began with the same accusation, and neither of them could prove anything. They took an infidelity test together during shore leave. The result confirmed his account — and the real outcome was that the argument stopped being the first conversation of every visit.
Three siblings had split their parents' savings without a document, as their parents had done before them. Two years later the sums did not add up and the family stopped speaking. A voluntary examination established that the shortfall came from an expense nobody had been told about rather than from a theft. They settled it privately in a fortnight.
The owner of a scooter and car rental firm suspected his manager of pocketing deposits during the high season. Firing him mid-August would have closed the business; keeping him meant working under suspicion. The manager requested the test himself. The result supported his account and the discrepancy turned out to be a bookkeeping error — the examination protected an honest employee rather than exposing a dishonest one.
People arrive with situations they have not discussed with their closest friends, and a lie detector test is not something anyone wants talked about afterwards. Discretion here is procedural rather than promised.

Most corporate enquiries here come from hospitality and property management — hotels, restaurants, rental fleets and villa services, where teams are assembled quickly for a season and handle cash and other people's belongings from day one. Companies use lie detector tests narrowly: to clarify a specific incident such as a shortage or a leak, to screen candidates for positions of trust, and to run periodic checks agreed in advance with the staff concerned.
Participation is voluntary in every case, consent is informed and in writing, and the data collected is handled under normal data-protection duties. A result informs a management decision; it does not replace a fair internal procedure, and we say so plainly to clients who expect otherwise.
Group testing. For five respondents or more we agree a per-case rate and a schedule built around the season rather than against it. Ask in WhatsApp or Telegram — we reply the same day.
Sessions are arranged in Athens, Thessaloniki, Patras, Larissa, Volos and Kalamata, and on the islands — Crete, Rhodes, Corfu, Kos and the Cyclades. Our Athens address is Kifissias Avenue 16, 11526; in practice most clients prefer the examiner to come to them, which for the islands simply means agreeing the date a little further ahead.
For a visit, any quiet closed room of about 10 m² is suitable: a room at home, a hotel room, a meeting room or an office out of season. Privacy and two uninterrupted hours are the only requirements.
When we reply: messages on WhatsApp, Telegram and Viber are answered daily, 08:00–22:00 local time.
You receive a signed report from a certified examiner setting out the methodology, the questions agreed in advance and the conclusion. It is used most often outside a courtroom — in private disputes, negotiations between relatives or partners, internal company decisions and family situations where someone wants their position documented. Whether such a report can be added to court materials depends on the jurisdiction and the type of proceedings, so discuss your specific case with your lawyer first and we will prepare the examination in the format they require.
Nothing needs rehearsing before a lie detector test. Sleep normally, avoid alcohol and sedatives the day before, eat as usual and allow enough time so that you are not arriving straight off a ferry in a rush. Prescribed medication is not an obstacle — mention it during the interview and the examiner will factor it in, as they do routinely.
Almost everyone is tense for the first ten minutes, and the method accounts for that — you will already have read and approved every question, so there is nothing waiting to ambush you. What does interfere is deliberate breathing control or muscle tensing: it shows up on the chart as clearly as a raised hand.
A lie detector test is safe and painless, but a few conditions make a result unreliable: acute cardiovascular or neurological illness, pregnancy, acute stress or bereavement, and alcohol or sedatives taken within the previous day. Anyone under 18 is tested only with the written consent and presence of a parent or guardian.
The examiner checks all of this during the mandatory pre-test interview, so candour there matters more than at any other stage. If you feel unwell on the day, moving the appointment costs nothing and protects the accuracy of the answer you came for.
A standard examination costs €365 — one subject, one topic, 1.5–2.5 hours including the pre-test interview, with the signed written report included. The online format is €175. Multi-topic and corporate cases are quoted after the free consultation.
Yes. Sessions take place in Athens, Thessaloniki, Patras, Larissa, Volos and Kalamata, and on Crete, Rhodes, Corfu, Kos and the Cyclades. The examiner travels to the address you name; a closed room of about 10 m² at home, in a hotel or in an office is enough.
Usually within a few days in Athens and Thessaloniki, and with more notice for the islands and the high season. Tell us your location when you write and we will name the earliest realistic date.
English, and on request Spanish, Russian or Ukrainian. We do not currently run examinations in Greek, so the session is held in English — the wording of every question is agreed with you beforehand, which is why the language is settled long before the test begins.
The report works best outside a courtroom — in private disputes, negotiations and internal company decisions. Whether it can be added to court materials depends on the jurisdiction and the type of proceedings, so agree the format with your lawyer before booking and we will prepare the examination accordingly.
No — and we check that ourselves before accepting a corporate booking. The examinee signs consent in person, may withdraw at any point, and a refusal cannot be treated as an admission. A hotel owner may invite staff to take a test; nobody can be marched into one.
It occurs in a small share of cases — usually because of a medical condition, medication, or a topic worded too broadly to test cleanly. We say so plainly instead of presenting an unclear chart as an answer, and depending on the reason we either reword the questions and repeat the relevant part at no extra charge, or advise that a polygraph cannot settle this particular question.
Yes, but only when three things line up: a parent or guardian consents in writing and stays in the room, the teenager genuinely agrees, and the questions are adapted to their age. A session forced on an unwilling teenager produces a bad chart and a worse relationship, so we decline those.
Free consultation — we will match the format, the language and the examiner to your situation
Describe the situation in a couple of sentences. We will come back to you, say honestly whether an examination will answer your question, and name the price and the nearest available date. The consultation costs nothing and commits you to nothing.
