Long gone are the days when Private Investigators are just retired police detectives. In this modern day they come from all walks of life — yes, the police and military services are still prevalent, but many come from university or other professions and then train to be a PI.
The bottom line is you may be academically qualified, but nothing beats the experience you learn on the job which is far more important.
Surelock has been established for over 30 years, founded by highly decorated Senior Detective Roy Herridge QPM, and now managed by former Scotland Yard Detective and past President of The Association of British Investigators Ron Harrison.
We have a dedicated, highly skilled, and experienced team of professional private investigators. We spent many years recruiting experts from the police, military services and the private sector.
