Best Private Investigators in Singapore

The 10 Best Private Investigators in Singapore

Looking for someone who can do a background check on a potential business partner? Well, consider yourself lucky because we’re here to share our picks for the best private investigators in Singapore.

Contrary to popular belief, private investigators aren’t needed only for criminal cases. Most of them help individuals regarding personal and business matters as well: to confirm if your spouse is cheating, for example.

Before we get to our list though, we’ll look at the cost of hiring private investigators on the island. We’ve answered a few questions about them as well, which you’ll see at the end of this article.

The Cost of Private Investigators in Singapore

Before hiring private investigators in Singapore, it’s important to understand how much their services typically cost and the factors that affect their rates. We’re going to admit right away that hiring one isn’t going to be cheap.

There’s a wide spectrum of factors that affect their prices, including location, equipment, type of work, duration of work, the subject, and the level of information to be obtained from the subject.

Even the least in-demand private investigators on the island could set off your back account by a huge sum, so better be prepared for everything to avoid being in conflict with your hired detective.

Private investigators do a broad range of work, such as general surveillance, background checks, finding a missing person, tracking movements of family members, and general investigation related to criminal cases, among others.

When it comes to general surveillance, most private investigators charge an hourly rate that ranges from $100 to $300, depending on their experience. This doesn’t include accommodation and transportation.

If the type of work requires more hours or days, other private investigation firms would charge a lump sum for their services, ranging from $1,000 to $6,000.

According to our research, the average cost of a 30-hour case is somewhere between $2,000 to $4,000.

We highly suggest comparing the charges and fees of private investigation firms as their fees aren’t monitored and regulated by Singaporean authorities. While there’s no doubt that this type of service is expensive, other firms may take advantage of that to charge their clients with ridiculously high fees.

Whether for local or foreign cases, International Investigators can plan and execute an accomplished scheme for your case. It ended up on our list based on two reasons.

First, compared to its competitors, it’s a private investigation firm that specialises on matrimonial and commercial cases. It doesn’t have the wide range services that other firms have, but its limited services allow it to focus each case.

Second, International Investigators knows how to prioritise the emotional state of its customers, as it mostly works with private individuals. You will not only receive technical and legal support but counselling as well to deal with what’s happening.

Its concern for its clients’ emotional wellbeing is enough for us to consider it one of the best private investigators in Singapore. However, there’s more to it than that.

International Investigators is open from Monday to Sunday, allowing customers to ask for help even during weekends. It’s also been praised for its excellent customer service and quick response to their queries.

It may be one of the largest private investigation firms in Singapore, but it has the expertise and dedication to help every client deal with a spousal or business problem.

Pros

  • Open seven days a week
  • Offers counselling
  • Competitive rates
  • Excellent customer service

Cons

  • Focuses on matrimonial and business cases

Customer Reviews

International Investigators have been covered by various media because of their incredible work. Many agree that they should be listed as some of the best private investigators in Singapore.

Jenny shared her own experience on Google Reviews:

“I was fortunate to be referred by a lawyer friend to International Investigators. International Investigators did an excellent task to prove that my ex-employee made false allegations against my company. This ex ex-employee was given a stern warning by the authorities and ordered to make compensation for breach of employment contract. Keep up the good work!”

Ivan Lim shared this comment:

“My relationship with my fiance deteriorated badly during the Circuit Breaker. I took quite some time before I decided to engage PI to check on her. True enough, she is having an extramarital affair with her superior who is married. Though heartbroken, I am grateful to International Investigators who displayed their  professionalism during the progress of the case till the end. Managed to call off the engagement in time, or I would have made a wrong decision and regret forever.”

Established in 2005, AK Global Investigation has been helping local and international commercial and government agencies for more than a decade now. Its long list of experience alone earns it a spot in our list of the best private investigators in Singapore.

When it comes to costs, it admits it doesn’t have budget-friendly investigation services compared to other firms. One thing’s for sure, though: its private investigators will make sure that you will see the results of your hard-earned money.

Another thing we like about AK Global Investigation is its expertise in cyber forensics. In fact, we believe that it’s one of the few investigation firms in Singapore that can obtain digital evidence like email traces and browsing history.

If you believe that you’re being watched, this private investigation company can help with that as well. It also provides bug sweeping service, which is a detailed physical and technical inspection of your home or office to locate surveillance cameras.

In case a client needs legal support, there’s no need for them to contact a separate law firm as AK Global Investigation offers its own litigation services. It works closely with experienced lawyers and reputable law firms on the island.
