Our team of highly experienced, multi-disciplined male and female private investigators in London are fully trained in all aspects of private investigation work – from practical skills, logistical work, due diligence, and more. Their dedication to achieving results and resolving your case is their main priority and they will work closely with you to ensure the best results possible are obtained for your investigation.

London is home to the largest and most diverse proportion of the British population, making it challenging to find an individual amongst the masses. Our Central London based office specialises in knowing the area inside-out, those operating in proximity, and how to deal with complex and sensitive issues. Our highly trained personnel have worked hard to acquire in-depth local knowledge and experience, allowing them to work quickly and effectively within this area

This large, fluctuating population requires a greater demand for private investigators than any other area in the country and because of this people want a detective agency that can provide a discreet and professional service.

In addition, many of the world’s largest companies and organisations are based in London offices – allowing them to obscure their actions and make it difficult to make a determination about their practice and interests. Because of this, the need to investigate all aspects of business such as corporate fraud and employee theft are extremely high. Whether it is criminal aspects, legitimate personal concerns, or questions about sincerity and character – Insight are here to cut through the noise and get to the truth.

Our services also include catering to concerns of a more severe nature – such as personal security, whether it be at work or home, and ensuring that those in your care remain safe. For such instances, we can provide security services such as CCTV, vehicle tracking and forensics to ensure your safety and provide a swift response in times of difficulty.

I can heartily recommend insight for any investigative situation the professionalism and dedication to the job in hand was exemplary


I was particularly impressed with the professionalism in which the agents carried out the observations and reported their findings and attended at the subsequent disciplinary hearings.
