Lie detector test in Wales
Three controlled examination rooms — Cardiff, Swansea and Wrexham — and the border towns of Chester, Shrewsbury and Hereford within reach of the rest. Welsh prices are English prices; it is Scotland that differs.

Your appointment
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.
What it costs in this region
£495 all-inclusive for one person, £695 for a couple and £295 each for three or more on the same day — the same figure at every room in Wales, with no travel charge.
The south is served from Cardiff and Swansea, the north-east from Wrexham, and mid-Wales is genuinely remote from all of them — Shrewsbury is the room most people from Powys use. Where no room is close the examiner travels, and there is no travel charge for doing so.
Where we test
Four towns in Wales.
Every one has a controlled examination room of its own. Choose a town for its addresses, its prices and what people there come to us about — or put your postcode into the form above and it will rank them by distance.
What we test for
Services we provide across Wales.
The same examinations, run to the same standard, at every office in the region — whichever of these brought you here, it works exactly the same way wherever in Wales you book.

Asked across Wales
The questions this region raises.
Do Welsh tests cost more?
No. Wales is on the same rates as England — £495 for one person, £695 for a couple. Scotland is the only part of the UK with its own price list, because examiners travel to it from England.
What about mid and west Wales?
The examiner travels at no extra cost. For Powys and the borders Shrewsbury is usually the nearest room; for Pembrokeshire and Ceredigion it is Swansea.
Can the examination be in Welsh?
Ask the helpline before booking. Question wording is agreed in advance and has to be unambiguous to the person being examined, so language is a question we would rather settle on the phone than on the day.
Why is the booking fee non-refundable?
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.
How many questions can be asked?
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.
Does it hurt?
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.
What if someone tries to beat the test?
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.
When do I get the results?
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.
What happens if I don't book an examination date within 30 days?
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.
Can I change my appointment date?
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.
What happens if I miss the pre-examination questionnaire deadline?
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.
What if the result isn't what I expected?
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.
Client reviews
What people say afterwards.
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 Wales alone.
Book in Wales
Talk it through before you decide anything.
The consultation is free and there is no obligation to book. Most people who call have never done this before — that is exactly what the helpline is for.
