🧩 What Influences the Cost of a Private Investigator in Nairobi?
1. Complexity and Duration of the Case
Simple cases like a background check may take a few hours. But complex fraud, surveillance, or cross-county investigations may span several days or weeks—raising overall costs.
2. Expertise and Licensing
Licensed and experienced investigators who offer admissible evidence and forensic reporting typically charge more than unlicensed individuals or freelancers.
3. Technology and Resources Used
Cases involving advanced surveillance, GPS tracking, or digital forensics require specialized equipment and trained professionals, which increases cost.
4. Travel and Logistics
If the investigation extends outside Nairobi or requires following subjects across multiple counties, transportation and per diem expenses are factored in.
5. Urgency or 24/7 Monitoring
Last-minute or time-sensitive investigations requiring immediate mobilization or night work may attract a premium fee.
✅ What You Should Expect from the Cost You Pay
When hiring a private investigator, ensure the cost includes:
- A detailed service agreement
- Confidentiality and legal compliance
- Regular updates or progress reports
- A final written report (and visual/audio evidence if applicable)
- Court-admissible documentation (if needed)
Cheap services may result in poor quality evidence, legal risks, or even scams. Always prioritize value over price.
🛑 Red Flags to Watch for
- Investigators who avoid written contracts
- Extremely low prices compared to market average
- No registration, license, or office address
- Vague answers about methodology or deliverables
