About National Private Investigators – know you’ve the right expertise in your corner

Why Hiring The Right Private Investigator Matters

When something as critical as the truth is on the line, having confidence in the facts you’re presented with is imperative. You’ve lived with doubts for long enough. But the private investigation industry is unregulated and, unfortunately, flooded with ‘detectives’ who use dubious methods to gather evidence collected illicitly that won’t stand up in a legal setting. Some will even overcharge for unnecessary detection methods when simpler solutions could easily be deployed to gather the proof you need. You should be able to trust that your private investigator has your best interests at heart. With National Private Investigators you can.

How Do You Know You Can Trust Your Private Investigator?

At National Private Investigators, we know the decision to hire a private investigator often comes at a difficult time for our clients. It’s often not a decision that’s taken lightly. That’s why we try to make sure people have considered all the options before moving forward. The good news is you don’t have to rely solely on gut instinct when vetting your PI. There are a few ways you can verify whether they really are up to the job. First, confirm they are members of the following associations – the Investigators Institute of Professionals (IPI), the Association of British Investigators (ABI) and the World Association of Professional Investigators WAPI. The ABI is how we measure high quality, pride, and the utmost integrity within the world of private investigations. NPI is a proud member of all three of these associations.

Who Is The Best Private Investigator In The UK?

Measuring how good a PI is before hiring them isn’t always easy. But if the values of the private investigator match your own that’s a positive indicator they will be a good fit for your case. NPI prides itself on its ethical approach to detection. We are a professional team who care deeply about the rules and regulations of our work. NPI is a legitimate business with a strict code of conduct. We are fully compliant with confidential data processes and our specialist private investigators have worked at a top level in the British military. Everyone is highly aware of the complexities surrounding the world of private investigations and surveillance so you can rest assured your case will always be in the very best hands.

The Ability To Uncover The Real Truth Lies In The Strength Of Your Investigation Team

The quest for the truth often requires specialist expertise and equipment. That’s why we have assembled a highly skilled team of more than 40 world-class surveillance operatives across the UK to focus on specific detection techniques. Our team is headed up by Jack Charman, founder and chief investigator at NPI.

Jack is an ex-army reconnaissance soldier, experienced in covert surveillance and all areas of intelligence gathering. His time in the army has given him a wealth of experience and knowledge which has equipped him to gather an outstanding team for National Private Investigators.

“In the army, our job was to get in close to gather intelligence on enemy forces – this included everything from enemy numbers and weapon systems to morale and supply routes. When we had all the desired information that could have been gathered, our team would extract undetected to present the intelligence back to our chain of command. The skills and techniques gathered in this pressured role in the most extreme environments enable me to lead our team and operate at the highest level for our NPI clients now, gathering essential facts and evidence they can rely on 100%.”

Paul - government-grade bug detection

Special forces trained, Paul leads our bug detection team who deploy a range of surveillance techniques using highly sensitive Government-grade detection equipment. Paul’s team stay at the forefront of detection technology to ensure they can carry out exhaustive bug sweeps that will uncover even the most sophisticated listening devices. Techniques includes thermal imaging, RF detection, Volt detection, non-linear junction detection, spectrum analysis and wide band detection.

Steve - for ingenious covert surveillance

When a job requires discreet surveillance we need equipment that will allow us to be in close range of our target without exposing our activity. Steve, our very own ‘Q’, is a master of covert detection devices, who develops a range of camera and tracking devices that can easily be concealed while evidence collection takes place. Unlike equipment that can be obtained on the mass market, our devices are designed with extended battery life and pinpoint accuracy. Ex-military, Steve is a self-confessed technical geek who deploys the latest equipment and detection techniques to ensure high-quality evidence is gathered.

Simon – a master of lie detection

The former counter-terrorism officer uses a state-of-the-art ‘Eye Detect’ device to detect minuscule movements in the eye. This technique eradicates room for human error or misinterpretation that traditional lie detection methods are susceptible to. Our lie detector tests can return accurate results within 10 minutes of testing.

Aaron – water-tight background checks

Aaron heads up our tracing and background check services for desktop investigations and uses a range of databases and software to delve deep into the data collection on the target subject to trace up-to-date details required by the client. Our checks go way beyond the obvious and, if required, we follow up with pretext enquiries to confirm the evidence we have gathered beyond doubt.
