A private investigation agency is paid for careful, discreet work done outside an office. Here is how to organise, train and supervise the people who do it.
Not sure what you need? Tell us about your business in six short steps and we will come to the first meeting prepared.
Share your requirementsA private investigation agency takes cases from companies, law firms, insurers and families: employee misconduct and fraud checks, claims enquiries, due diligence on counterparties, asset and missing-person tracing and matrimonial matters. Many investigators are former police, defence or corporate security staff, joined by analysts, field associates and a case manager who writes reports. Work happens in the field and at desks, often at irregular hours, and a case can last days or months. Clients pay for discretion, accuracy and a report that can withstand questioning. Each investigator holds sensitive information about people and companies, and the agency's name depends on how it is used. Workload is lumpy and cases are held by individuals. See also HR for security services.
These are the places the people side of this kind of business tends to give way. The rest of this page works through them.
HR here has to work for each of these groups, not only the office. The set-up below is written with all of them in mind.
Client names, case details and findings must stay inside the agency, and a single careless conversation can end a relationship.
An investigator knows the file, the contacts and the story, so his leaving mid-case puts the work and the client at risk.
Long hours, odd locations and encounters with hostile people are part of the job, and support for field staff is thin.
Clear, accurate, defensible reports are what clients pay for, yet writing standards differ between investigators.
A large corporate matter takes every available person, and a quiet month leaves skilled staff idle.
Investigators from field backgrounds and analysts from desk backgrounds disagree about methods, pace and priority.
People work out of sight, and judgement about what is appropriate rests on their own sense of limits.
Start with the topics that matter most here: Policies, Compliance and Governance; HR Operations and Governance; Retention and Attrition Management. Then work through the rest. Each topic is written for security services, not in general.
Policies a manager can apply, and obligations with owners and dates.
An HR function that runs the same way every month.
Who leaves, when, why — and which of them mattered.
How many people, in which roles, by when — and what they will cost.
Structure, reporting lines and who is allowed to decide what.
Requisition to joining, the same way every time.
A first day that is the same for the fifth joiner as the first.
Records, attendance, leave and the day-to-day HR that must simply work.
Salary structure, payroll inputs and a month that closes on time.
Goals, reviews and ratings that hold up in a conversation.
Training planned from need rather than from the calendar.

Communication, recognition and the conditions people actually work in.
Two routes — one for complaints, one for conduct — kept separate.
Induction, records, incident reporting and follow-through.
Resignation to relieving letter, in a defined order.
Records that survive people, and approvals that do not queue.
A short monthly pack management actually reads.

Write a clear policy, limit access to files to those who need it, explain the consequences and set an example. Culture matters as much as the paperwork.
If notes and evidence are held centrally and a second person has been briefed, the case continues. Otherwise the client may be lost with the person.
Use a template, a writing guide and a second-person review. Share good reports internally, with client details removed, so standards are visible.
Agree check-in times, a rule on when to withdraw and a debrief after difficult cases. People who feel supported make better judgements.
Review cases weekly, plan training and research tasks in quiet weeks and keep a small group of trusted associates for peaks. Ask a qualified professional about engagement terms.
We would ask how confidentiality is stated to staff, where case files live, and how reports are reviewed before they reach a client. Support for field staff and uneven workload would also come up. A sensible first piece of work is a clear written conduct and confidentiality rule, together with a report standard. We would then send a written scope for you to approve before any work starts.
