Transparent pricing, hourly rates, retainer minimums, and what drives the final bill." lang: en --- All articles (https://exerogroup.cz/blog)Personal Investigations (https://exerogroup.cz/blog/category/personal-investigations)June 2026 # Private Detective Pricing in Czech Republic By Exero Group · Exero Group, Prague Image: Czech private detective pricing and rate guide by Exero Group (https://akreodypygwbrmmgpmsq.supabase.co/storage/v1/object/public/blog-images/2026-06-01-pricing.jpg) "How much does a private detective cost in the Czech Republic?" is the first question almost every client asks. This guide breaks down how Czech investigative firms actually price work, what drives the final invoice, and what red flags to watch for when comparing quotes. ## Hourly rates vs day rates Most reputable Czech detective agencies (in Czech often called _soukromé očko_) price surveillance and field work either by the hour or by an 8 to 12 hour day. Hourly rates in Prague typically run between CZK 700 and CZK 1,800 per investigator per hour depending on complexity, language requirements, and whether the work requires a two-person team or specialist equipment. ## What actually drives the price - **Team size.** Static surveillance can sometimes be handled by one operator; mobile surveillance in city traffic almost always needs two or three. - **Duration and unpredictability.** A subject with an erratic schedule means more standby hours. - **Language.** English-, German- or Russian-language work commands a premium because the pool of qualified Czech investigators with that capability is small. - **Evidence standard.** A report meant for a Czech court must be collected and documented far more carefully than an internal management briefing. - **Travel.** Outside Prague, expect mileage and accommodation on top of the hourly rate. ## Retainers and minimums Serious agencies work on an upfront retainer, typically CZK 25,000 to CZK 75,000 depending on scope, drawn down against actual hours. Any firm willing to start without one is either inexperienced or planning to bill aggressively at the end. The retainer protects both sides: the client gets a defined budget ceiling per phase, the agency gets paid for the time it has already committed. ## Why "cheap" detective work is the most expensive The Czech market has a long tail of unlicensed operators who quote half the market rate. Their reports are almost always unusable in court (GDPR breaches, evidence collected unlawfully, no chain of custody), which means the client pays twice: once for the bad work, and again for a licensed firm to redo it properly. The price gap usually disappears once you add the cost of a failed case. ## How Exero Group quotes We quote in writing after a free initial consultation, with the scope, deliverables, hourly rate, estimated hours, and a clearly defined cap.

Hourly rates in Prague typically run between CZK 700 and CZK 1,800 per investigator, depending on complexity, language requirements, and whether the work requires a two- or three-person team. Day rates for 8 to 12 hours of field work are usually negotiated for longer engagements. ### Why do reputable Czech detective agencies require a retainer? Serious agencies work on an upfront retainer of roughly CZK 25,000 to CZK 75,000 drawn down against actual hours. The retainer caps the client's budget per phase and ensures the agency is paid for time already committed. Any firm willing to start without one is either inexperienced or planning to bill aggressively at the end. ### Are cheap, unlicensed detectives a real saving? Almost never. Reports produced by unlicensed operators usually fail in court because of GDPR breaches, unlawfully collected evidence, or missing chain of custody. The client then pays twice: once for the bad work and once for a licensed firm to redo it. The headline saving disappears as soon as the case fails. ### What factors push a Prague detective quote higher? Team size (mobile surveillance in city traffic almost always needs two or three operators), an erratic subject schedule, working language (English, German, Russian), court-grade evidence standards, and travel outside Prague are the main drivers. ## Need investigative support on a similar matter?
