Used for various investigations from infidelity to criminal behaviour, Eye Detect's quick results support its use in the UK's criminal and civil courts, bolstering the reliability of legal proceedings.


In addition to employing advanced investigative technologies, Trojan Investigations prides itself on being a part of the United Kingdom Professional Investigators Network (UKPIN). Membership of UKPIN is considered prestigious within the industry, signifying adherence to high professional standards.

Our London Private Investigator Services


Surveillance

All our private detectives have received specialist training and are experienced in conducting covert operations and evidence gathering (including gathering photographic evidence / audio evidence legally to the highest quality). During surveillance operations, our clients are constantly updated, and we are open to changing objectives dynamically should any situation change.


The types of surveillance we conduct are:


  • Domestic/matrimonial disputes such as an extramarital affair or cheating partner, substance misuse and child custody issues.
  • Insurance fraud investigations, for example, fraudulent claims.
  • Employee monitoring, such as moonlighting and any other surveillance requested on employees/directors.

Any evidence we gather will be presented to a standard the legal industry requires.



GPS Vehicle Tracking

Watch the location of your target from the comfort of your home. We use the best GPS vehicle trackers on the market. Our trackers are deployed on any vehicle where you can monitor its location 24 hours a day from the comfort of your home using an app on your smartphone or desktop computer.


Vehicle tracking can also be used with physical surveillance to gather evidence of the vehicle's occupants' activities.


This app can provide a detailed route the target vehicle has taken throughout the day, which is all dated and timed. When you have collated your evidence, we remove the device from the vehicle, leaving you to disseminate the tracker information to whoever you wish.



Tracing

Tracing missing persons, debt tracing (debtor tracing), long lost family members. We operate a 'No Find, No Fee' policy. We have access to numerous databases if you are looking for someone and do not know where to start. Combined with our investigative skills, we can offer unparalleled rates of success.


Tracing can be used for various reasons, such as missing persons, bad debtors and locating ex-partners.



Employee Monitoring

Keep an eye on your staff in and out of the workplace. Do you want to see what your employees are really up to?


We supply undercover operatives to join your workplace as employees to gain behind-the-scenes knowledge. We will document the client's needs and present the findings in detailed reports.


We also follow employees when they are out of their normal place of work. Are they moonlighting or behaving in a detrimental manner that could affect the client's business? They could be using illicit drugs, drink driving or involved in industrial espionage, passing company secrets and tactics to a rival.


We are here to provide results.



Background Checks

Knowing every detail about your target can be a great benefit. We carry out discreet and comprehensive background checks on any individual with a suspected hidden past or criminal background, with the subject of the check being none the wiser.

Our services build an intelligence picture for concerned partners, parents, employers and business partners.

So, what can they show?


Full names, dates of birth, marriages, divorces, National Insurance number, passport and driving licence details. Any criminal history the subject may have. A full credit search showing any black marks, such as CCJs. Current business interests and property ownership.


Not sure about someone? Contact us!



Process Serving

Process serving is the service of legal documents on behalf of solicitors and the courts. It is also the service of legal documents to a defendant or individual involved in a court case.


We provide a fixed fee for serving documents. We serve orders issued in the civil or family courts and, if required, can collect documents for service from any office, UK court, or your client.



Lie Detection

More accurate than a polygraph test – working alongside Lie2me. Trojan Investigations offers lie detection services using Eye Detect, the next-generation lie detector, which detects lying through minor eye changes.


We offer lie detection services to UK private, public, and commercial clients.


The Eye Detect system studies the eyes during the test and transmits the information to an encrypted database; this database runs the test data via the algorithms, and then it will rapidly and without human mistake or interpretation give an impartial and accurate result to you within minutes.


There is no getting away from the truth since the computer assesses participants, the test administrator cannot modify test results, and all the test data is secured and tamper-proof.
