Question 1

Am I overreacting by even looking at this?

Accepted Answer

No, and the fact you are asking suggests you already know that. Nobody researches polygraph testing for fun. The question that brought you here has been costing you sleep, focus, or both, and a controlled test is the only clean way to retire it. Those who close this tab to think usually never return, and the question stays.

Question 2

What will show on my bank statement?

Accepted Answer

Your bank statement shows a short LPI reference, our parent company, and nothing else. There is no mention of polygraph or London Polygraph Services anywhere on the transaction, which matters when accounts are shared.

Question 3

What if my partner refuses to take the test?

Accepted Answer

Consent is not optional in this work: a pressured examinee produces worthless charts, so we test volunteers only. The offer of a test, made calmly, is itself revealing. Acceptance says one thing, refusal another, and a discussion about why can settle more than the test itself sometimes would.

Question 4

Can anxiety or nervousness cause me to fail the test?

Accepted Answer

No. Scoring compares your responses between question types rather than measuring how calm you are, so an honest but nervous examinee reads as honest. Almost everyone tested is nervous.

Question 5

How much does a lie detector test cost in London?

Accepted Answer

A single issue test with London Polygraph Services is £495, booked and paid online with nothing added later. The price includes the pre-test interview, the examination and the full written report with recorded charts within 24 hours.

Question 6

How accurate are polygraph tests in the UK?

Accepted Answer

Run to American Polygraph Association standards, a single issue polygraph test achieves decision accuracy in the region of 90 to 98 percent. Examiner training, equipment, venue and question technique determine where in that range a test sits.
