The experience and expertise you'll find under the Surelock umbrella is second to none. Founded by highly commended former senior Metropolitan Police officer Roy Herridge QPM, Surelock's directors, consultants and operatives are drawn from a variety of disciplines, including the police, fire service, military and private and public sector.
I am Roy Herridge QPM and I am the founder of Surelock. After 35 years in The Metropolitan Police Service I retired with the rank of Detective Superintendent, the most highly decorated officer at this time and have been awarded the Queens Police Medal for services to The Capital. I have carried out investigations in a number of European countries and Asia since leaving the police service and working within our company Surelock.
Ron used my services as a client and I was impressed with his professionalism and care he showed for his client he entrusted to me. I have known Ron and the team at Surelock for well over 10 years. Ron represents many well-known international brands. He has extensive experience and in-depth knowledge in the world of brand protection / anti-counterfeiting, and is very results-focused in his work.
Surelock has experience in contractual management and project management audits within the construction industry which seeks to identify and prevent future losses. We will scrutinise the commercial and contractual management of building projects and examine the functions of these projects to determine the cause of any losses.
We provide the best experts using state of the art equipment to help combat domestic issues such as infidelity. Domestic surveillance, sometimes referred to as "cheating partners" can provide evidence required to assist clients and their legal cases where instigated. We are able to provide evidence for court both verbal and photographic and evidence to the client in a sensitive and clear format.

Sometimes in life things happen which one is unable to manage without the assistance of professionals. In my case the service I received from Surelock was extremely helpful. I am very impressed and grateful to the inspectors for their expert advice and support, and definitely made the right decision in seeking Surelock services. I would like to express my gratitude to all involved and if ever needed help again I would not hesitate to contact them.

Just look at this extract explaining just how professional the main man of the ABI is, Mr Ron Harrison himself! At least grace this poor individual with a reply sir.
“Surelock Private Investigator Mr Ron Harrison made a false witness statement against my mother & I. He tried to frame us for an offence which carries up to ten years in prison. His witness statement stated that my mother and I had been selling counterfeit clothing and had been damaging the brands by selling inferior clothing.
Thanks to the grace of God, he was caught out red handed.
The witness statement was entirely false as
