A few quick steps. The £125 booking fee secures your appointment and comes off the total; the balance is due 48 hours before the test.
Where we test
Every examination happens in a private, controlled room booked for you alone — never a home, never a hotel lobby. Put the postcode into your satnav; on the business parks it is the building number that matters.

What Cardiff asks us about
Cardiff is a university city and the caseload shows it. The pattern that recurs is a parent who has worked out that their son or daughter is taking something bought online to keep working, and a student who will not discuss it — partly because admitting it at university carries consequences of its own.
Nothing is reported to a university, an employer or anybody else, and the examiner is not there to judge anyone. The test can only go ahead if the person taking it agrees to it, which with a student is usually the harder conversation — the helpline will talk you through having it.
What we test for
The same examinations, run to the same standard, at every office in the UK — whichever of these brought you here, it works exactly the same way in Cardiff as anywhere else.

Client reviews
Independent Trustpilot and Google reviews. A review never records which office the examination was at, so these are clients from across the UK rather than from Cardiff alone — it is the same examination and the same examiners wherever it happens.
Asked in Cardiff
If yours is not below, the free helpline will answer it — including when the answer is that a test is not the right thing for your situation.
No. Nothing goes to a university, a college, an employer or anybody else without written permission. That is usually the first thing a student wants to know, and it is worth telling them before you ask them.
You can book and pay. They still have to agree to sit it, and the examiner will stop if it becomes clear they are only there because they were told to be.
Yes — Swansea, Newport and Wrexham among others, at the same £495. The examiner travels to you at no extra cost.

No. Your examination in Cardiff is held at Brunel House, 15th Floor, Brunel House, 2 Fitzalan Road, which is booked for your appointment and nobody else's. A polygraph measures small physiological changes over a couple of hours, and it needs a quiet, private room with no interruptions to do it — a doorbell, a neighbour through the wall or a family member in the next room is not a neutral setting, and it is not one we can guarantee in somebody's house. Our examinations take place in a dedicated, private setting designed for polygraph testing, which is what gives the controlled conditions and the confidentiality the examination depends on. If getting to an office is genuinely difficult, call the helpline on 0800 861 1058 before you book and we will talk through what is possible.
No. It is £495 all-inclusive for one person wherever you book in England, Wales or Northern Ireland, including Cardiff — the price does not change with distance. Scotland is the one exception, priced separately.
Because the work starts before you arrive. An examiner reviews your case, agrees the questions with you in advance and prepares the examination — and the slot is held for you and nobody else. That is also why booking waives the 14-day cooling-off period, which is set out in the terms and conditions. If you are unsure whether a test is the right step, call before you book rather than after.
Up to 4 specific-issue questions, alongside the profiling questions the format requires. Each is repeated at least three times during the test, because consistency across repetitions is what makes the result readable.
No. The blood pressure cuff stays inflated during the test and can feel tight — about like having your blood pressure taken at a surgery. Nothing else is felt at all.
Countermeasures were a real problem with older equipment. Modern instrumentation records the attempts themselves — deliberate movement, controlled breathing, pressure applied out of sight — and a trained examiner sees them in the data. An attempt to distort the test is itself a finding.
A full written report reaches you by email within 24 hours of the examination, or within 48 hours by tracked post if you prefer that. Every report is checked and verified by a second examiner, so what you receive is a qualified opinion rather than one person's reading.
Your examination date needs to be agreed within 30 days of the original booking date. If it is not, we may close the booking and the £125 booking fee stays non-refundable — clause 3.15 of the terms and conditions has the exact wording. If your circumstances change, call the helpline before the 30 days runs out rather than after.
Yes, with at least 48 hours' notice, and the new date has to fall within 30 days of the original booking date — see clause 3.9 of the terms and conditions. Call the helpline to make the change; it is time-sensitive, so a call gets it done faster than email.
You have 24 hours from booking to return it, by text or SMS link. Miss that window and we reserve the right to cancel the appointment — clause 3.5 of the terms and conditions sets it out. If you need more time, call the helpline before the 24 hours is up rather than after.
It stands either way — No Deception Indicated, Deception Indicated or Inconclusive — and no refund is due once the test has been carried out and the report provided, regardless of the outcome. Clause 3.12 of the terms and conditions sets it out. If you are unsure whether a test is the right step, the free consultation before you book is the place to ask.
