About Us
Stepping into the world of private investigation, it’s common to be met with a haze of scepticism and doubt. An industry that should be built on trust often finds itself mired in doubt and uncertainty. That’s why, in March 2016, driven by my personal experiences in a covert reconnaissance unit of the British Army, I took it upon myself to illuminate this dimly lit path. Thus, National Private Investigators was born.

From Military Precision to Civilian Service
The British Army’s covert reconnaissance taught me many things – discipline, attention to detail, and, above all, integrity. These core values were noticeably missing in many corners of the private investigative world. Seeing this disparity, I was compelled to take action, hoping to meld my military expertise with a sincere commitment to honesty in civilian service.
