When Your Interests are at Stake, You Need the Truth

The 4-Step NPI Process

A lot of people are unsure about whether to enlist the help of a Private Detective in Essex. They fear their problem may become public or that the process might be overly complicated. The reality is the team at National Private Investigators have decades of combined experience and understand to their core how to keep confidential information confidential. As for the process itself, we’ve refined it to 4 simple steps:

1. Contact Us

It all starts when you get in touch with NPI and describe your situation to one of our case managers. They’ll determine if a Private Detective is right for you or if you should go to the police.

2. Information

If we determine you would benefit from a Private Detective we will then ask for as many details as you can provide. Remember, the more we know the faster we can uncover the truth.

3. Investigation

Once we have all the information you can provide we determine which investigative methods will work best and get to work.

4. Report

Within 24 hours of concluding our investigation, we will provide you with a final report. Though you may find some of it disturbing, the report will contain the truth, nothing less.
