People come to National Private Investigators for a variety of reasons, including:

  • They suspect infidelity on the part of their partner.
  • They need a thorough background check performed on a prospective hire.
  • They are going through a divorce and need to know their partner is not hiding assets.
  • They suspect a staff member of being a mole.
  • They suspect someone is stealing from the company coffers.

There is no need to live with suspicion and doubt.

What most clients want to know when they first get in touch with us is what we can do for them: what specific benefits do we offer? Whilst the specific benefits we’re able to offer often depend on the nature of the case under consideration, all of our clients stand to enjoy the following when taking advantage of our investigative services in West London:


  • Highly Effective Administrative and Field Operatives – The most immediately apparent benefit of our private investigative services will be the highly-skilled operatives who maintain contact with you throughout the case. Both our office and field operatives are industry veterans, possessing the knowledge and skills required to perform first-class investigative work in a wide variety of environments. Using their skills and knowledge, they will swiftly uncover the truths you are seeking and put your mind at rest in the process.
  • Reliable Results – Thanks to our top operatives and our meticulous approach to investigative work, we are able to guarantee 100% reliable results to all of our clients. In the event you decide to hire NPI to conduct an investigation on your behalf, you can depend on us to deliver accurate, verifiable and verified information at the conclusion of the case.
  • Ethical Behaviour – Our regular clients know that they can rely on us to behave ethically at all times, which is one of the reasons they keep coming back. Not only are we able to achieve impressive results, sometimes in surprisingly short timeframes, we are able to do so without resorting to any form of immoral, unethical or illegal behaviour. This is an important benefit for any person or organisation that needs to maintain an unblemished record of behaviour in all that they do.
  • Relief From Anxiety – Perhaps the most important benefit we are able to provide is lasting relief from anxiety. When you don’t know if your suspicions are well founded or not, when you’re just not sure who can and can’t be trusted, it can be very difficult to truly relax, even for just a few minutes. The anxiety that such uncertainty causes makes it hard for you to ever let go completely, which can fray the nerves further, intensifying the anxiety as the vicious circle is completed. The evidence we deliver will eradicate your uncertainties, thereby removing the root cause of your anxiety.
  • Evidence on Which to Base Future Actions – By eradicating the uncertainties with which you have been dealing, the evidence we uncover will also provide you with firm ground on which to base your future actions and decisions. Our private investigators in West London will do everything in their power to ensure you have all the details you require to move on with your life once the case is concluded.


The first step toward solving your problems is to contact National Private Investigators. We are waiting to provide you with the information and evidence you need to move forward.
