Private Investigators UK

We conduct a variety of Private Investigations including those related to infidelity, child custody, cohabitation and more.

Our corporate investigators help our clients identify emerging risks so that they can take appropriate steps to protect themselves and their interests.

Personal injury claims are one of the most common types of fraudulent insurance claims. By surveilling someone we can help you determine if that person is truly injured.

Insurance fraud alone costs UK businesses billions of pounds per year in losses. If you suspect someone is filing a fraudulent claim the team at NPI can help.

Whether you need to track down a debtor, a contractor who did shoddy work or a loved one who suddenly vanished, our highly-trained tracking agents can find them.

We employ a variety of leading-edge and long-established techniques and technologies to find out if the person you are about to put in a position of trust is worthy of that trust.

Sometimes it’s unwise to get too close to someone being surveilled. A better approach is to attach a GPS device to their vehicle and track their movements remotely.

Our expert bug-sweeping service exposes digital spying devices no matter how cleverly they have been hidden in your home, business or vehicle.

People lie for any number of reasons, but if you have placed them or intend to place them in a position of trust you need to know if what they’ve told you about themselves is the truth.

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.


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.

At National Private Investigators, our guiding principle is clear and unwavering: the pursuit of truth. We’re not here to offer investigative services but to revolutionise them. Our mission is grounded in putting people’s rights and interests at the forefront of everything we do. We aim to usher in a new era in private investigation, where each step is taken with sincerity and genuine service.

We’re not only reshaping the industry; we’re actively striving to purge it of unethical practices that have tainted its reputation for far too long. Our vision is clear: a realm of investigation where every client, irrespective of their stature, can step in with confidence. Whether you’re a multinational corporation or an individual seeking answers, at National Private Investigators, you’re promised transparency, integrity, and compassion.

Our team is our pride. A collective of seasoned professionals, each a master in their domain. Be it intricate surveillance operations, meticulous background checks, or the delicate task of people tracing – we have experts for every need. What’s more, every member of our team is bound by our shared ethos – to transform and uplift the investigative industry, bridging trust gaps and fostering genuine connections.

Beyond our primary services, we’re passionate about educating our clients and the general public about the importance of ethical investigative practices. We host workshops, webinars, and interactive sessions, ensuring that the values we stand for are disseminated far and wide.

Looking forward, our goals are ambitious but straightforward. We aim to be the gold standard when it comes to private investigations – setting benchmarks not just in results, but in the approach, ethics, and relationships we build along the way. With technology and methods evolving, so do we. Staying updated with the latest techniques, tools, and training, we’re ever-ready to serve in the best possible way.
