National Private Investigators Ltd is a London-based private investigation and intelligence agency providing discreet investigative support across the UK and internationally.

The company is led by Jack Charman, a former British Army reconnaissance soldier who moved into private investigation after leaving the military in 2016. Since then, Jack has built NPI around clear evidence, lawful investigation methods, and complete discretion for clients facing sensitive personal, legal, corporate, and security matters.

NPI specialises in surveillance, enhanced intelligence reports, due diligence, TSCM bug sweeps, background investigations, asset searches, fraud enquiries, people tracing, digital exposure assessments, and corporate risk investigations.

The agency works with private clients, law firms, companies, family offices, high-net-worth individuals, and international partners who require reliable evidence and confidential handling. Its work often involves complex personal disputes, corporate misconduct, insider threat concerns, reputational risk, and pre-litigation intelligence.

NPI’s approach is practical, ethical, and evidence-led. Every case is handled with proportionate methods, clear reporting, and a focus on giving clients the facts they need to make informed decisions.

National Private Investigators Ltd is based in London and operates throughout the United Kingdom, with trusted international contacts available for cross-border enquiries.
