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 Google 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 Google 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 Google 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 Google Luciano TomlinsonTrustindex verifies that the original source of the review is Google.

What Is A Corporate Investigator?
Reliable investigative support isn’t a luxury in today’s corporate world — it’s essential. At PIUK, our corporate investigators handle commercial investigations and corporate fraud investigations across the UK. We take on everything from single-incident reviews to complex, multi-site cases, helping organisations spot fraud, misconduct, and compliance issues before they get worse.
A corporate investigator is a trained professional. We look into financial crime, employee misconduct, and internal threats. We use forensic analysis, interviews, public records checks, and digital surveillance to gather evidence that holds up.
Whether you run a private equity firm or a multinational company, our job stays the same: leave no stone unturned. We identify risks, protect your intellectual property, and gather evidence that supports legal action if needed.
Why You Might Need Corporate Investigation Services?
There are plenty of reasons businesses come to us. Suspected fraud. Data leaks. Missing assets. A breach of contract. Concerns about compliance. Due diligence before a big acquisition.
Common cases include employee theft and payroll fraud. They also include data breaches and supplier fraud. Other cases include disputes between shareholders or partners. They may also involve sabotage and insider threats.
Why Are We the UK’s Most Trusted Corporate Investigators?
We’re known for integrity, accuracy, and discretion. Our investigators have worked across many industries. They know how to handle sensitive cases without making things worse.
What sets us apart? Honest, ethical conduct. Careful handling of sensitive information. A real understanding of business environments. And the know-how to help stop the same thing happening again.
Comprehensive Corporate Investigation Services
Our commercial investigations cover many areas. These include insurance fraud, vehicle tracking, and financial audits.
We also handle employee misconduct and disciplinary cases. We investigate intellectual property issues and asset tracing.
We provide due diligence and background checks. We look into theft and identity theft. We support whistleblower cases and data protection breaches.
We also handle accounting audits, forensic financial reviews, cybercrime, and IT forensics. We handle compliance investigations, contract disputes, and surveillance or counter-surveillance. Every case is handled with confidentiality, accuracy, and full legal compliance.
How Our Investigative Process Works?
It starts with a confidential chat. We talk through your goals, your concerns, and whatever evidence you already have. From there, we scope out the case and put together the right team.
Then we get to work—surveillance, interviews, data analysis, legal documentation. We build a full picture instead of jumping to conclusions.
You’ll get regular updates as we go. You’ll also get a detailed final report with findings, evidence, and clear recommendations. We can also support HR meetings or court proceedings if needed.
The Benefits of Hiring Corporate Investigators
The benefits add up fast. You catch fraud or misconduct early, instead of months down the line. Your compliance gets stronger. You’re protected against financial loss and damage to your reputation.
Contract disputes become easier to resolve. You get a clear picture of your risks, instead of guessing. And if it comes to legal action or an employee hearing, you’ll be prepared, not scrambling.
We also offer corporate forensic investigations when you need a deeper look at financial records or a cyber incident.
Reasons for Conducting a Corporate Investigation
Some problems need expert help. These include repeated mistakes in financial reports. They also include suspected bribery or corruption.
Another issue is unauthorised access to confidential files. Poor leadership can lead to disciplinary issues.
Anonymous whistleblower complaints may also need expert help. Sudden changes in an employee’s behaviour can be a warning sign.
We investigate every lead properly. Our findings hold up in disciplinary hearings and in court.
Misuse of information and Employee Misconduct
Workplace issues like harassment, bullying, or abuse create a toxic environment. They can also put your business at legal risk. We interview staff and witnesses, review internal messages, and gather evidence of policy breaches. We work alongside your HR team to build findings that hold up.
Financial Abuse:
Financial misconduct is often hidden — fake invoices, missing assets, false expense claims. We use forensic accounting to check financial records, spot conflicts of interest, review contracts, and uncover hidden fraud.
Corruption and Sabotage:
When data gets leaked or systems get sabotaged, speed matters. We use cyber-forensic tools to trace the leak, work out how it happened, and find out who’s responsible. Our focus: recover what’s lost, limit the damage, and stop it happening again.
The Legality Of A Corporate Investigator in the UK
UK corporate investigators have to work within the law — the Data Protection Act, GDPR and employment law. We stay firmly within those rules, so every piece of evidence we gather is legal and admissible.
