Private Lie Detector Test - Our private lie detector test is specially developed to assist couples in learning the facts about their relationship.

The Private Lie Detector Test

When there is an underlying element related to a specific event which may have happened, the test can identify the truth of the matter. Suspicion erodes trust and the test will either reinstate confidence or confirm a partner’s worst fears. Either way, both partners are able to move forward with their lives when they are in full possession of the facts. Our specialist polygraph examiners frequently deliver the infidelity lie detector test service to private clients all over the UK. Consistently the truth is established and our clients are able to make informed decisions based on the verified report they receive after the test. More often than not the report helps repair relationships rather than destroy them.

What type of questions can be asked? The questions proposed during an infidelity lie detector test are designed to reveal the facts. For example, you will want to know if you partner has been unfaithful, whether any sexual contact has taken place, how often and perhaps with how many people or specifically with whom. You may want to know how long a particular affair has been going on. When a relationship began and/or ended can also be queried. It’s usually not advisable to ask questions that relate to what a person believes or what their opinion is on a matter. Depending on how complicated an issue is an infidelity lie detector test can take up to 2 hours. Usually up to 8 questions will be proposed with 2 to 3 of them related specifically to the issue that has caused the problem. The remainder are questions the examiner needs to ask for metrics and behavioural purposes in building a profile of the subject.
The full scope of case work involved in the infidelity lie detector test process spans around 2 hours. The first step is to discuss your case with one of our highly confidential and discreet client support personnel. This is a free consultation when we’ll consider the information you provide and tell you whether or not the test will help you. If your circumstances are suitable a reservation can be made for a mutually agreed time, date and location to conduct the test. On confirmation of your booking it is necessary to pay a non-refundable booking fee of £150. After the payment has completed we will send you a text message (sms) and email together with a secure access to our online pre-examination assessment form which must be completed within 24 hours. Once completed by you (the client), or by the subject(s) of the examination, and returned to us you can then proceed to the final booking stage where the remaining fee is taken. Once received a booking email with be sent to you confirming, date, time and office location of our test. Secure online booking system As can be expected from a confidential service, our online booking system is highly secure and simple to use. Instructions appear on screen to enable you to complete the process easily with the minimum of fuss. You can also choose the option of a home (residential) test or one in our controlled offices at a location nearest to you.
On the day of the test the total time to complete all aspects can be up to 2 hours. If the test is conducted at your home, our accredited, specialist examiner will arrive discreetly in a normal (unbranded) car. If it is to take place in one of our offices, you check in with our receptionist by giving your names. It’s not necessary to state why you are there, she will already know. Our examiner will be notified of your arrival and greet you. Both parties can be present for the pre-examination interview when your relationship will be discussed in detail including the suspicions or other issues you have. Questions you may have stipulated during the reservation process or those you want to be proposed will also be discussed. The examiner will suggest the correct wording for each question to ensure you get the answers you require. The context and wording is important with close ended, definitive questions that ensure an accurate result is achieved.
When the test is completed, if the results are irrefutable immediately, we are obliged to notify our client. (Our client is always the person who made the booking). If both parties are present and they are comfortable with the results being made available to both our examiner will provide them verbally shortly after the test. However, this is only possible if the examiner deems the results to be conclusive. As with all of our reports the data derived from the test including charts, video and transcripts has to be analysed. After the analysis which ensures you get the authentic results the report is verified and sent to you. Usually this will be within 24 – 48 hours sent by email or ordinary mail – the choice is yours. The examiner who conducted the test analyses the data and a second examiner verifies it before the report is sent.
Through our network of controlled offices in all major towns and cities in the England, Scotland, Wales and Northern Ireland, we are well positioned to serve our clients with Lie Detector Tests when they need them. We can also reach out to those wishing residential tests, including those in rural locations, in the evenings and over the weekend.

Commercial Lie Detector Test

Ensuring that staff members maintain the optimum standard of honesty and integrity is important to any organisation. Over recent years, with the increase in fraud, theft and other illegal activity many businesses have found it necessary to review their loss prevention policies. Our clients come from a broad spectrum of commerce and industry and have benefited significantly from the implementation of our Business Polygraph Testing service.

Business Polygraph Testing

Pre-employment screening

Small businesses don’t have the budget or resources of the large Human Resource departments in large corporations. Introducing the polygraph into your pre-employment screening process is not only affordable but also prevents unquantifiable loss. Business polygraph testing allows you to confirm the details in CVs you have been given by potential candidates. You can verify that everything you have been told is the truth as well as gain some insight into the character of the individual. Among other checks that you can do such as criminal background, educational qualifications and work experience the polygraph is the best tool to validate the information you gather.

Legalities of Business Polygraph Testing

There is very little legislation related to the use of polygraph testing in business. However, an employee is not obliged to take a test and cannot be forced to do so. The best way to implement the process is to make submission to testing part of the employment contract. Or to send a memo outlining that testing is a new policy about to be introduced accompanied by a letter that employees are requested to sign agreeing to be tested. Most honest employees will have no problem in complying.

Credibility Assessment Division

The Credibility Assessment Division was founded on a core framework to assist businesses in the public/private sector to be able to suitably assess the authenticity of personnel within the realm of their organisation.

Random testing of existing employees

Random testing is a policy adopted by many of our clients to ensure the workforce remains loyal to the company and doesn’t steal from it. The introduction of tests sends a clear message to employees that the business has a zero tolerance toward fraud and theft. Questions can be formulated to match the individual duties of staff members. The polygraph can also be used if a specific employee is suspected of criminal activity.

Working out questions that need to be propose We work closely with you to formulate appropriate questions specific to the truth you need to find. Whether in the pre-employment screening process, theft, fraud or anything else that is bothering you. Normally up to 8 questions are asked with 2-3 of them relevant to the matter you are concerned about. The other questions proposed are for profiling purposes, related to behaviour and metrics. You may want to know if your data has been passed to a competitor, or what the subject knows about theft of equipment or assets. Questions must always be related to factual matters rather than opinion. The test may take up to 2 hours depending on how complex the issue is which includes the pre-test interview.
Business Polygraph Testing can take up to 2 hours. Firstly, you’ll need to discuss your requirements with us.  We can do this on the telephone or organise an online conference. If you want to order Business Polygraph Testing on a regular basis for recruitment screening or random checking we can arrange to meet up at your offices or ours. Initially we’ll gather information from you and make a decision as to whether polygraph testing will benefit your particular circumstances. If so, you will be able to book the service online using our secure reservation system when you can choose the date, time and location for the test. When the booking is confirmed you pay a £150 reservation fee which is not refundable. As soon as the payment has been cleared you will receive an sms (text message) and an email confirming payment and giving you access to our online pre-test assessment form.  This needs to be completed within 24 hours. On completion by you, someone acting on your behalf or the subject(s) of the polygraph test, the outstanding balance of the fee must be paid. Thereafter we will send you an email confirming all the details of the test including location, date and time. Secure online booking system Because of the sensitivity of our work, we provide the optimum in secure online booking together with a highly confidential and discreet service. On screen instructions guide you through the booking procedure that is easily understandable. During the process you will be able to designate where you want the test to be conducted with a choice of office locations near you or onsite at your business premises.
Pre-Test Interview 2 hours should be set aside for the employee on the day the test takes place, longer if they are travelling to one of our offices. On arrival at our office our examiner will meet your employee after checking in with our receptionist. Thereafter, the pre-test interview will commence when a number of questions will be discussed including those that you have predetermined with us. The purpose of the pre-test interview is to ensure the subject is relaxed and understands completely what the test is about. The predetermined questions and the way they are worded are suggested by the examiner since they need to be defined and close ended. The most accurate results from the polygraph come with perfectly worded and contextualised questions are asked.
Business Polygraph Testing Results and Report If the issue has been a simple one, and the result is considered conclusive at the end of the test, our examiner will immediately apprise the client verbally if required. To be precise our client is the individual who booked the test. Unless otherwise advised in writing that we may share the results of the test with a 3rd party we will never do so. Detailed analysis of the resulting transcripts, video and charts will be undertaken by the examiner who performed the polygraph test. It will then be verified by another equally qualified and accredited examiner before the report is sent to the client, usually within 48 hours. There are a many benefits for companies to introduce Business Polygraph Testing into the recruitment or loss prevention strategy. You can rely on us to advise you how to implement it effortlessly without distressing your staff.
We have controlled offices located in most major cities and towns throughout the UK where testing is performed. Alternatively the test, subject to environmental conditions, can be conducted at your place of business or in the employee’s home.

Thank you, first let me say this was what my family and I needed and the price was so affordable.I took a polygraph in the past with another company. The guy who did the first test was some kind of PI and obviously not a polygraph operator with much experience.I never knew that polygraphs were available to the public, but I am so grateful that they are.I would highly recommend Lie Detector Test Ltd to anyone that may be having personal or non-personal issues.

My partner and I had been going through some issues that resulted in the need to take a lie detector test. For the sake of my privacy I won't go into too much detail but the test showed both of us were telling the truth all along. We were able to move past our problem and our relationship is stronger because of it. I was very pleased with the services of Lie Detector Test Limited. They treated us with dignity. Taking a lie detector test is never easy but they made it as smooth and painless as possible. They did a wonderful job and I'd happily recommend them to friends and family the next time something comes up that necessitates a lie detector test.

Running a home cleaning business is tough. People trust their most valuable belongings with us and we just can’t afford for something to go wrong. This is the main reason for which we have very serious background check-ups when we hire new people. A polygraph is also a must. We’ve been using the services of the Lie Detector Test UK for years and they’ve always delivered.

Ex reckons I was messaging someone on Facebook but he messaged me and I don't even know who he is.

My work recently experienced a business theft where we had several suspects. We were very sure of one person in particular who had contacts with the office but they were adamant that they didn’t take it. We suggested that they take a lie detector test with Janet and they reluctantly agreed. When they were proven guilty, they admitted to the crime and said that they believed that they were sceptical of the test until it proved to be true.

After booking an appointment at the London office I was a bit hesitant to go due to the weather conditions. However, the team was nice enough to allow me to reschedule for the following week. The examiner was EXTREMELY professional and diligent - not to mention I cannot fault the explanation that me and my partner were given. Even though I do hope that I don't have to do it again anytime soon I would still recommend it to anyone without hesitation.

Brilliant and reliable service I was hesitant to use a lie detector test in case my worries within my relationship turned out to be true but the whole process really helped put me at ease. From start to finish, the process was clearly explained and carried out in the controlled rooms, in an easy to find Regus building in London. The truth has really helped both of us and I would highly recommend Lie Detector Test UK, brilliant service.
