Each situation requires a different investigation service approach. Understanding the available private investigator services in Singapore allows you to move forward with confidence.
How Private Investigator Services Are Regulated in Singapore
In Singapore, private investigation services and activities are regulated under the Private Security Industry Act. Licensing is regulated by the Police Licensing & Regulatory Department (PLRD) under the Singapore Police Force.
One of the mandates of the regulatory agency is to ensure that every licensed private investigator and all but one in Singapore complies with professional standards.
Key compliance principles include:
• Agency licensing under the Private Security Industry Act
• Registration of professional investigators under police licensing rules
• Lawful surveillance practices during investigation
• Proper documentation for Singapore courts
• Evidence collection within legal boundaries
A private investigator with a license should abide by these rules in every part of the investigation process. This framework safeguards both the focus of the inquiry and the clients proper to use the assistance.
If you are hiring a private investigator in Singapore, one of the most important things is to check that the company is licensed by Singapore Police Force. It safeguards your case and ensures that evidence could still stand in courts in Singapore if required.
At Baker Street Private Investigator, our team of private investigators operates under this legal framework throughout Singapore.

Surveillance & Field Observation
A team of professional investigators works on an investigation with surveillance to record behaviour patterns and gather evidence.
Private investigator surveillance is neutral and documented, observing without revealing.
Common surveillance cases include:
• suspected infidelity or adultery involving a cheating spouse
• suspicious activity involving business partners
• insurance-related monitoring
• behavioural observation connected to matrimonial investigations
Professional investigators are discreet regarding surveillance and they keep every single investigation confidential.
Professional private investigation agencies have the right to carry out surveillance operations, keeping them legal and properly documented.
Commercial & Corporate Investigations
Businesses frequently engage private investigator services for internal corporate investigation cases. Corporate risk, fraud investigation, and employee misconduct investigations are common across industries.
Corporate investigation services may include:
• background checks on employees or business partners
• fraud investigation involving financial misconduct
• workplace misconduct verification
• conflict-of-interest investigations
Companies throughout Singapore often engage a trusted private investigation agency to manage corporate cases that require discreet fact verification.
At Baker Street Private Investigator, we regularly assist organisations across Singapore that need professional investigation support for sensitive corporate matters.

Private investigator services for personal cases may include:

A private detective working on matrimonial investigation cases must follow strict confidentiality standards.
