We have been providing our clients with a unique, simple, cost effective yet high value and very results driven service since 1991.  UK and Worldwide Specialist Detectives. After working in the Detective Industry for over 30 years Christopher Knowles and Peter Smithson one day over lunch were discussing how they had noticed that whilst Detective and Investigation work is a very specialist area requiring unique skills and contacts, companies often over charge and over complicate their services and offerings. Inspired by this they decided to set up Low Cost Detectives in order to provide clients a unique, simple, cost effective, yet high value and very results driven service.
