At Trojan Surveillance, we thrive on the thrill of running covert investigations – and nothing is more satisfying than getting the evidence required by our clients.
For many years, private investigation has been out of reach to most individuals due to large companies charging grossly inflated rates to cover their large profit margins – Our mission at Trojan Surveillance is to make the surveillance industry more accessible to both individuals and businesses.
We pride ourselves on honesty. We will absolutely never take on a new client without a thorough consultation, ensuring there are appropriate grounds for any investigation to proceed.

Our founders set out to do just this in 1990 with over 60 years’ experience in surveillance and reconnaissance in the Military and Police Service including hostile environments in the UK and internationally and we only employ former covert surveillance specialists and detectives with a similar experience. Trojan Surveillance is a business that recognises the importance of building a strong team and keeping profits margins modest, ensuring both satisfied clients and a motivated team.

Always on top of technology, we are equipped both with state of the art technology and seasoned knowledge of the industry, empowering our teams to carry out successful covert investigations.
