John provided my company a brilliant service. Surveillance was needed to check if an employee was really off sick or not. We were provided with a very professional and fast service, and a very clear, detailed report. This helped the company to obtain all the evidence that we needed. I Will definitely be using John again. Thank you.


The service i received was brilliant. Very professional and discreet. I had a feeling that my partner was cheating on me and unfortunately it turned out i was right.

What Can A Private Investigator Investigate Legally In Preston?

When working in Preston, a Private Investigator (PI) must follow the rules set by UK law. Important rules like the General Data Protection Regulation (2018), the Investigatory Powers Act (2016), and the Regulation of Investigatory Powers Act 2000 protect people’s privacy and safety. It’s important to choose a PI from a company that puts a high priority on following these laws, protecting clients, and respecting human rights.

Trained investigators are very important for keeping the law in order. By joining security groups like the ICO (the UK’s independent authority), private investigators promise to keep your information secret. PIs don’t have the same legal rights as police officers when it comes to things like arresting people or entering private land without permission. It is against the law to pretend to be a police officer for personal reasons.

PIs use a variety of investigation techniques to make sure they do the best work possible within the limits set by the law. Safety is the most important thing, and PIs are required to avoid doing harm on purpose. Hiring a private investigator in Preston is a legal and effective way to solve problems.

We Understand Your Needs

What Sets PI UK Apart From Other Preston Investigation Agencies?

We find that some PI agencies are too cold and clinical in their approach. The investigators can get tunnel vision, without really listening to your needs. While collecting evidence is important, we think this approach can take away from the quality of service that you receive.


We’re client-focused, so we’ll make sure you get the results you want, while making sure you feel supported and understood. Please get in touch with us for friendly, professional advice and a free, no-obligation consultation of up to 30 minutes.
