Private Investigator Singapore

If you believe that doing a background check on a possible business partner is important, look no further as we feature in this article the best private investigator (PIs) firms available in Singapore.

Though there are numerous PIs in Singapore who are ready to work on your case, but you really don't want just any one. You want a true professional who can find the answers to all of your questions.

Despite what many people believe, private investigators aren’t just for criminal cases. They help individuals regarding personal and business matters. One example is to know whether your spouse is faithful to your marriage or not.

Before, we jump to the list, let's take a glimpse first to the cost of hiring these PIs.

The Cost of Private Investigators in Singapore

Hiring a private investigator is never going to be cheap, but you need to understand how much it usually costs. You’ll need to consider many factors when deciding what works best for you, such as location, equipment, type of work, duration of work, the subject, and the level of information to be obtained from the subject.

So you better be prepared for everything to avoid getting into conflict with your hired detective because even the least in-demand private investigators in Singapore could cost you a fortune.

Private investigators do a broad range of work, an example is general surveillance. With general surveillance their typical hourly rate is between $100 to $300, depending on experience. They also do background checks, finding a missing person, tracking family members' movements, and general investigation related to criminal cases, among others. 

Based on our research, the average cost of a 30-hour case is between SGD$2,000 to $4,000. Thus, if you happen to require a job that spans to more hours or days, expect to pay in lump sum ranging from SGD$1,000 to $6,000.

While this type of service is costly, many other firms might charge their clients with ridiculous fees since these companies are not regulated by the Singaporean government. Thus, we encourage you to compare charges and fees offered by these private investigation agencies.
