What is a Private Investigator Retainer?

A retainer allows clients to secure dedicated investigation hours on a weekly or monthly basis. This structure is particularly suited to complex or ongoing matters such as long-term surveillance, corporate investigations, and legal support.

Retainers offer predictable costs, priority scheduling, and efficient case management without repeated onboarding.

Our approach prioritises value, reliability, and defensible outcomes rather than cost-cutting at the expense of quality.
