Location and test environment

The test must be administered in a quiet area. It could be on business premises or in a quiet room. Our expert operatives can travel across the UK and Europe to meet you at any location you prefer.

Can we administer foreign language tests?
At Polygraph 1 UK, we have a team of highly skilled translators. We can conduct the tests in any language of your preference.

Can the polygraph test results be affected by nerves?

Function and costs

How does the polygraph function?
It records the physiological changes occurring in the body as the questions are asked. Sensors are attached to your chest, arm and fingers. These detect the changes in the body when a lie is told. The test questions are formulated after a discussion prior to the actual test.

How much does a polygraph examination cost?
Prices are discussed and agreed after a discussion with the client. An initial free of charge consultation is undertaken on the phone prior to meeting with the client, before the examination is conducted. At the conclusion of the polygraph test, a full report will be provided.

We accept all major credit and debit cards.
