Tracing missing persons

People need to find other people for a variety of reasons, from lost relatives, old friends, heirs and beneficiaries, witness in legal proceedings and last but certainly not least, debtors.


Nationwide Investigations provide a wide range of surveillance services throughout the UK and abroad. Surveillance is often an important element in many aspects of an investigation.

Service of Legal Process

As all lawyers are fully aware the fast and efficient service of legal process is a crucial part of litigation.

Professional Witness Services

The role of our Professional Witness Service is to provide dedicated surveillance and expert witnesses to Housing Associations, local authorities. But we provide international professional witness services through our associated offices.

Insurance Investigation

Insurance fraud is as diverse as the types of insurance policies that are available, although it can be classified in two ways as either hard fraud or soft fraud.

Computer Fraud Investigation

Investigating computer-related fraud is generally a difficult and very time-consuming subject. It can be a labyrinth for the uninitiated.

Counterfeit & Piracy Investigation

Product Fraud is estimated to cost the legitimate owners millions of pounds each and every year. Forgers, imitators and counterfeiters do not just confine themselves to luxury products of international fame.

Polygraph Lie-Detection Services

Polygraph is a generic name for an instrument which is commonly known as a ‘Lie Detector’. Contrary to popular belief, it does not record directly whether a person is lying or telling the truth; it records changes which take place in the body during stress.


Covert listening device’s which are more commonly known as bug’s are normally a combination of a miniature radio transmitter with a microphone . The use of bugs, called bugging, is a common technique in surveillance and in particular industrial espionage.


Forensic science facilities are an important aid to the legal profession in cases of civil disputes, arbitration involving matrimony, protection and industrial accidents.
