Lie Detector Test in Cardiff
Wales’s most trusted polygraph service. Professional, discreet testing from £395 in the heart of Cardiff.
You Shouldn’t Have to Keep Wondering
When the truth matters, uncertainty isn’t something you can just live with.
It often starts with a feeling that something is off, or a story that doesn’t quite add up. A clear, professional result changes that and it starts with one call.

What Unanswered Questions Actually Do to People
Over time, the story you tell yourself becomes harder to separate from what actually happened. Relationships deteriorate not because of the truth, but because of the space where the truth should be.
Clients at our Cardiff office often tell us the relief wasn’t just about the result. It was about finally having something real to work with instead of spiralling on possibilities.
Of the couples who come to us with infidelity concerns, 70% are able to repair and move forward after the test. The truth tends to do far less damage than months of unresolved doubt.
A Result You Can Finally Do Something With
Certainty isn’t the end of the story. For most people, it’s where their story starts again. Whatever the result, you will leave our Cardiff office with clarity and a professionally verified conclusion that gives both parties a factual starting point.
Some use it to rebuild. Others use it to make a decision they’d been putting off for months. What they all have in common is that they stopped being stuck and started moving.
