How much does a private investigator cost in Paris in 2026?

The Aquila Group systematically adapts its billing procedures to the operational realities of each assignment.

Beyond the indicative fee schedule, our approach is based on optimization: our years of experience allow us to accurately assess the number of hours required as early as the scoping phase. This ability to plan ahead prevents budget overruns and allows us to offer consistent flat-rate packages tailored to the project’s objectives.

We therefore prioritize hourly packages tailored to the assignment, rather than simply accumulating hours. This approach ensures greater transparency for the client and overall control over the cost of the investigation.

In addition, we offer a sliding-scale pricing structure based on the number of hours committed and the duration of the assignment. The more structured the assignment is over time, the more the hourly rate is optimized.

A minimum engagement of 5 hours is always required to ensure that the investigation is conducted effectively and that the results are usable.

Our rates in Paris in 2026 and throughout France

Hourly rate schedule
Configuration — Hourly rate excluding VAT

Setup	Hourly rate (excluding tax)
An investigator	From €72 to €95 per hour, excluding tax
Two investigators	From €140 to €160 per hour, excluding tax
Team of 3 or more investigators	Custom pricing

Why is there this variation?

The rate depends on the technical complexity of the assignment, the geographic location, the level of urgency, and the technical resources required.

In addition:

A fixed processing fee of 150 € is charged when each assignment is initiated
Investigation reports—which are well-structured and admissible in court—are billed at €360, including tax.
An emergency fee for response within 24 hours applies, charged at an additional €250 per investigator deployed

These elements include, in particular, the preliminary analysis, the strategic structuring of the assignment, and the rigorous documentation of evidence.

Business Trip and Travel Expenses

Travel expenses are determined in advance and included directly in the quote as a percentage of the fee. They cover all logistical costs associated with the assignment: travel, fuel, mileage allowances, tolls, parking, and meals.
This approach ensures complete budget control: no cost overruns, no surprises.

Additional expenses may be incurred only if the assignment requires it (lodging, long-distance travel, meals during the assignment), and always after prior approval.

Our packages include all the resources necessary for the success of the mission: investigative techniques, deployment of personnel, operational equipment, and the development of investigative scenarios when the situation requires it.

The Aquila Group relies on a comprehensive team with complementary expertise: attorneys, bailiffs, notaries, OSINT experts, specialists in data recovery and detection, and cybersecurity experts, as well as a team of investigators tailored to each situation (male or female detectives, mobile units, motorcycle or vehicle surveillance).
We offer operational solutions for every type of situation.

Guaranteed transparency: No additional fees will be charged without prior approval.

The Aquila Group operates within a strictly regulated framework:

– Our investigators hold certifications issued by the CNAPS
– We are bound by the strictest professional confidentiality
– Our work is governed by an obligation of means (human and material resources ), not an obligation of results

The Aquila Group guarantees that all investigators are CNAPS-certified, that the company is fully GDPR-compliant, and that evidence is admissible in all courts.

Why Invest in a High-Quality Survey?

Hiring a private investigator in Paris is a financial investment, but above all, it is an investment in obtaining redress for a wrong suffered.

Finally, each proposal involves operational planning: determining staffing needs, anticipating on-site challenges, and selecting investigative techniques. The goal remains the same: to produce a result that is legally admissible while optimizing the resources deployed.

The cost of an investigation is therefore not limited to an hourly rate; it reflects the ability to analyze, target, and execute.
