A Light in the Darkness

Nefarious players are determined to keep their actions hidden and will often go to great lengths to do so. Our job is to determine their motives, follow the breadcrumbs and shine a light into the dark corners where they hide. Whether the target is a wayward partner or a competitor determined to bring you down, we get to the truth and present it to you so that you can formulate an effective response.

Our 4 Step Process

The Private Investigation process encompasses the following 4 steps:

1. Contact Us

When you contact NPI you will speak to one of our friendly and highly trained case managers. They will listen intently as you explain your situation, ask questions when necessary and determine whether your case would benefit from a Private Investigator in Clapham or if you would be better served going to the police. If they conclude you would benefit from a Private Investigator we will proceed to the next step.

2. Information

Now that we have a basic idea of the situation and the players we will need you to provide as much background information as possible. Our case manager will make suggestions as to what type of information would be useful, but the bottom line is this: the more you can provide the faster we will be able to get the results you need.

3. Investigation

Once we have sufficient background information our Private Investigators get to work. In some cases that will mean performing surveillance of a person or location. In other cases it may mean conducting record searches, monitoring social media activity or performing background checks on particular individuals. In most cases, we will pursue multiple avenues of investigation simultaneously.

4. Report

After the investigation has concluded we will issue a final report within 24 hours. This report will contain all the relevant information we obtained on the subject in question and will be up-to-date and accurate. What you do with the information will be up to you.
