Private investigation costs frequently asked questions.
Here are some of the most frequently asked questions when it comes to cost and hiring a private investigation service.
Can I pay a fixed fee?
On some of our investigation services, a fixed fee is possible. Process serving is an example of this where a fixed fee is paid and we then attempt to deliver your legal documents up to three times. A service such as this is perfect for a fixed fee as we know the number of hours involved, the distances that will need to be travelled and expenses that we will incur.
Other services such as covert surveillance on the other hand don’t lend well to a fixed fee as it is not known how many hours will be needed to gather the evidence you need. To help you with this you can block book our hours so that costs are affordable.
What is a private investigator retainer?

A private investigator retainer is when you hire us for a set amount of hours, usually on a weekly or monthly basis and we work for those required hours on your case. A retainer is a great way of handling more complex investigative cases while keeping the money spent on our services affordable to you.
Can you price match another investigator?
Our private investigator fees are competitive and are a result of the experience of our operatives. Our fees are put in place so we have enough manpower, equipment and time to get you the best result possible.
Cheap private investigator – Should you hire one?
Hiring a cheap private investigator may be better than doing the work yourself but as the private investigator industry isn’t regulated anyone can say they are an investigator. Hiring a cheap investigator is a potential sign that the person offering the service isn’t confident in the ability to do the job. I understand that hiring a cheap private investigator may be something you are considering but I would urge you to consider how important the job at hand is for you.
How do I hire a private investigator?
The cost of hiring a private investigator is important, pay too much and you may not be able to afford a full service for sufficient evidence collection and pay too little and an agency could drag their feet prolonging the service while not collecting the evidence in a sufficient manner which won’t hold up in court.
