It depends on the operation: the number of operatives, the hours and days deployed, whether the subject is static or mobile, vehicle requirements, location and urgency all drive the price. Professional surveillance is typically charged by operative hour or as a fixed budget for a defined deployment, agreed in writing before anyone is fielded, and Tremark quotes exactly on that basis.
A single operative observing a fixed address for a morning is the entry point; a mobile subject usually needs two or more operatives and vehicles to follow safely and without exposure, which scales cost with reliability. Duration is the other lever: fraud validation often needs observation across several separated days to evidence a pattern rather than a snapshot. Travel, unsocial hours and specialist requirements such as covert video in challenging environments complete the picture.
The cheapest quote that misses the evidential moment is the most expensive option available. What determines value is planning: pre deployment intelligence so operatives are in the right place at the right time, briefing tight enough that the footage answers the legal question being asked, and reporting that arrives court ready rather than needing rework. Those disciplines, described in what a surveillance report includes, are where experienced providers earn their fee.
