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.

Mobile and Active Surveillance Services in the UK
When you need answers, having the right evidence can make all the difference. At Private Investigations UK (PIUK), our skilled investigators provide mobile and active surveillance services. We support individuals, businesses, solicitors, and insurance companies across the UK.
Whether you worry about a partner’s behaviour, suspect employee misconduct, or need legal evidence, our experienced detectives can help. Every investigation is planned for your situation, done with full discretion, and focused on the facts you need.
We understand that contacting a private investigator isn’t always an easy decision. That’s why we’re committed to making the process straightforward, confidential, and professional from your initial enquiry.
What Is Active Surveillance?
Active surveillance is the process of monitoring a person or location in real time. Instead of using old information or assumptions, investigators watch events as they happen. They record key evidence throughout the investigation.
This type of investigation is often used when you need reliable information quickly. It can help establish someone’s routine, confirm suspicious behaviour, or provide evidence for personal, legal, or business matters.
At PIUK, we carefully plan every operation before it begins. Our skilled private investigators choose the best approach for your case. We gather accurate evidence and stay discreet all the time.
How Mobile Surveillance Works at Private Investigations UK?
Mobile investigations allow our team to follow a subject as they travel between different locations. This helps us build a clear picture of their movements and activities throughout the day.
Depending on the situation, our detectives may use an unmarked vehicle, follow on foot, or use both methods. We make every decision to keep the investigation as discreet as possible while maintaining clear observations.
Our operatives use unbranded cars equipped with GPS and communication tools to ensure we stay on the subject’s trail without being detected. Before any investigation begins, we’ll discuss your concerns, explain how the process works, and agree on the best strategy. Throughout the investigation, our team adapts to changing situations so we don’t miss valuable evidence.
Surveillance Methods and Transportation Used
Every case is different, so we never use the same approach for every investigation. Our experienced investigators assess each situation before deciding on the best way to collect reliable evidence. Depending on your case, we may use:
- Mobile observations using unmarked vehicles.
- Foot observations in busy public places.
- Static monitoring from suitable locations.
- A combination of investigative methods.
Our team trains to blend naturally into different surroundings. This allows us to gather evidence without drawing unnecessary attention or disrupting the investigation.
Good planning and experience are just as important as the equipment we use. That’s why our investigators focus on collecting accurate information that can support your case.
Bespoke Surveillance for Private and Corporate Clients
No two clients come to us for the same reason. That’s why we tailor every investigation to your individual needs.
For private clients, our private investigators often help with relationship concerns, family matters, missing person enquiries, and other cases. In these cases, you may need clear evidence before making an important decision.
For businesses, our detectives support internal investigations involving suspected misconduct, fraud, theft, insurance claims, and other workplace concerns. We understand how important it is to protect your business while handling sensitive matters professionally.
From your first phone call to your final report, you’ll receive a confidential service designed around your goals.
Corporate Surveillance Solutions
Businesses can face many different risks. Whether you suspect employee dishonesty, fraud, or risks to company assets, getting facts early can stop bigger problems later.
Our skilled private investigators work with businesses across the UK. We provide discreet investigation services to help employers make informed decisions.
Corporate investigations may be suitable for:
- Employee misconduct.
- Insurance fraud.
- Theft investigations.
- Long-term sickness concerns.
- Due diligence enquiries.
- Protecting business interests.
Our team handles every investigation with professionalism and complete confidentiality. We work hard to minimise disruption while collecting reliable evidence that supports your business.
Private Investigations and Relationship Surveillance
Relationship concerns can be difficult and emotionally stressful. If something doesn’t feel right, it’s natural to want clear answers before making important decisions.
Our experienced detectives carry out discreet investigations to help establish the facts. Instead of guessing or being suspicious, we collect solid evidence to help you understand the situation better.
We also assist with family-related investigations and missing person enquiries where appropriate. Every case is treated with sensitivity, respect, and complete confidentiality.
If you’re not sure about needing an investigation, our helpful team can explain your options for free.
Discreet Surveillance Equipment and Techniques
Modern technology plays an important role in every investigation, but experience is what delivers results.
Our investigators use professional equipment to record observations and collect evidence where appropriate and lawful. Our investigators can take photos, record videos, and write clear reports about their observations.
Just as important is the experience of our team. Staying discreet and observing at the right moment allows us to gather trustworthy evidence without interfering with the investigation.
This combination of skill, planning, and technology helps us provide a professional service that clients can trust.
