Contacted PIUK for a time sensitive matter, spoke to a lovley chap called john who offered me the best advice in regards to my dilemma. Over the moon with the quality of detective work carried out, can't thank them enough. Highly recommend to all👌Posted on Mr AutomatticianTrustindex verifies that the original source of the review is Google. When I suspected my spouse of infidelity, I turned to John for help. His investigation was conducted with utmost discretion and sensitivity. The evidence he provided was clear and indisputable. While the truth was painful, it was necessary for me to move forward. John's support and professionalism throughout the process were invaluable. He truly understands the emotional aspect of such cases.Posted on marta mendelssonTrustindex verifies that the original source of the review is Google. Answering your answer, a big 😂🤣. I am sure you thought it was a case of a man with two identities; a big detective's case like in the films! 😎 One in a life time! Poor John!. Had it been true what you say, you wouldn't have been hiding, you would have answer my phone calls, emails, messages. Anyway, If anybody is interested, please contact me to show proof. Kind regards (Review: As a detective, a failure. His first report was about a wrong person, John mistook the individual with his brother but, as we could use one single line of his 15 pages report, I gave him a second opportunity. However, instead of doing a good job this time, the detective has done nothing and, what is worse, not only is unable to comply with his contract or to recognize he has not the detective skills and tools needed for the job but has been hiding for the last two weeks. That is to say, as detective a failure and as a person, rubbish.)Posted on Kelly SoperTrustindex verifies that the original source of the review is Google. I had been put in contact with John as I was looking to get a lie detector test in on myself. I was abused as a child and none of my family believed me. 26 years later John has helped me get the closure I so desperately needed to move on with my life and to finally prove I wasn’t a liar. My experience with John was amazing. Obviously I was very nervous about the whole process and having to discuss this with a stranger but he made me feel at ease and was very professional. John was very reassuring and respectful of my situation. The results were almost instant even though I was told it could take a few hours. The test was very professional and easy to do and worth every penny to get the results I’d been seeking for so long. Thank you so much John I highly recommend his servicesPosted on Luciano TomlinsonTrustindex verifies that the original source of the review is Google.

Infidelity Private Investigators in the UK
Nearly a quarter of married men admit being unfaithful
According to YouGov, nearly a quarter of married men in the UK admit to being unfaithful. In other words, suspicion like yours is far more common than most people realise.
Infidelity and cheating can destroy a relationship. However, so can making accusations without proof, which is exactly why so many people turn to us before saying anything to their partner. If you suspect your partner of infidelity, a private detective can help you find out the truth. Before you read on, we highly recommend our guide to Signs of a Cheating Partner.
When the signs are there, our experience shows we gather proof in around 90% of cases. As a result, most of our clients leave their investigation with real clarity, one way or the other. We’ve built our infidelity investigations methods over the past 20 years, and on this page, we answer the questions we hear most.
Naturally, every case is different, so we offer a free 30-minute consultation to every prospective client before anything begins. Contact us today to speak with one of our experts.
Infidelity Investigations uncover the truth
Confrontation Gets You Nowhere
Confronting your partner without evidence rarely works. After all, someone willing to cheat is usually willing to lie about it too, and nobody admits to an affair they’re not having. Consequently, you’ll end up in an argument with no real answers and possibly a damaged relationship on top of your original doubts.
By contrast, running a private investigator infidelity check gives you evidence your partner can’t argue with. If we find nothing, you still gain genuine peace of mind and avoid an unnecessary argument altogether. Either way, you come away with something confrontation alone could never give you: certainty
How an infidelity investigation can help you
Try to Act Normal
First, we ask our clients to carry on exactly as normal. It’s understandably hard to resist calling your partner out, but discretion matters throughout the investigation, and your partner must not suspect anything is happening.
If your partner finds out our cheating partner investigators are on the case, we may lose our only chance to gather solid evidence. Therefore, we ask you to keep your behaviour consistent and to avoid overcompensating for hurt feelings with unusually affectionate gestures.
If you’re struggling to hide how you feel, prepare a plausible explanation for your mood in advance, such as work stress or a disagreement with a friend. That way, you protect the investigation and give our team the best possible chance of success.
Hiring a private investigator to expose an affair
Discretion is Key
We hold ourselves to strict standards of discretion and confidentiality, so we ask you to do exactly the same. Above all, keep your infidelity investigation to yourself, and avoid discussing it with anyone outside the process.
We don’t recommend telling a friend, even one you trust completely. After all, it only takes one person passing that information to someone else, and you can’t always know who your friends know. Likewise, don’t rely on a friend simply because they live far away or share no mutual friends with you. There’s still no way to know who they might tell.
If you genuinely can’t keep the details to yourself, choose someone who keeps information confidential as a matter of course, such as a solicitor or a counsellor. This way, you protect the integrity of your case from start to finish.
FREQUENTLY ASKED QUESTIONS ABOUT INFIDELITY INVESTIGATIONS
Married couples and people in exclusive relationships make up the majority of our clients. That said, we also work with clients in newer relationships who simply want clarity before committing further.
Most clients notice a change in their partner’s behaviour long before they come to us. However, a gut feeling rarely holds up on its own over time, so hiring an investigator remains the surest way to know for certain.
We ask you to look out for specific signs before requesting our help. Click here for more information, and get in touch once you’re ready to take the next step.
Every case is different, so we look closely at your circumstances before discussing next steps. Rather than guess at a figure, we prefer to understand your situation first. Call us or contact us for a free, no-obligation consultation, and we’ll talk you through exactly how we can help.
We find out where your partner goes and who they see. Additionally, we trace people and run thorough background checks to build a complete picture. Once we gather enough evidence, we present it all clearly in your final report, so you can make an informed decision with confidence.
We operate a nationwide network of private detectives, so we guarantee coverage wherever you are in the UK. Furthermore, we offer international services on an individual basis, meaning distance is rarely a barrier to getting the answers you need.
Most of our infidelity investigations rely on covert surveillance, which means physically following the person involved and recording video evidence.
That said, we’re also seeing more digital and “online-only” affairs since the pandemic, where no physical contact takes place, but someone carries on a deep emotional affair through social media instead.
Our investigators bring genuine digital forensics experience to these cases. Provided the work stays legal and GDPR compliant, we’re glad to carry out a digital investigation into your partner as well.
Most of our private detectives come from public sector investigation backgrounds. In fact, our agents have experience in government intelligence and the armed forces, which is exactly the kind of background this work demands.
