What Does a Private Detective Agency in London Do?
A private detective agency in London offers many different investigation services. These services are designed for both personal and professional needs. Some people hire investigators because they suspect cheating. Some need help locating a missing friend. Some businesses want to protect themselves from fraud or dishonest employees. The work of an investigator is to find the truth using legal methods.
Here are some common services offered:

Surveillance
Surveillance means watching someone’s activity without them knowing. A private detective follows the person, observes behaviour, and captures photos or videos as proof. This is commonly used in cheating cases, internal company issues, or suspicious activities.
