Background Checks

A Background Check will include, when available, a criminal background check, marriage and divorce records, lawsuits, bankruptcies, property records, an address search, phone numbers, relatives & neighbours and a wide variety of other.

Surveillance Services

Maybe your partner is not being as faithful and honest as you, a business associate might be trying to defraud you or perhaps someone you care about has started a habit that is going to be harmful to them. Our surveillance services can determine if you need to take any action.

Cheating Partner

It is often the ‘not knowing’ that is the worst aspect of infidelity in a relationship. At UKPI, our cheating partner investigations and detectives can remove the doubts or set your mind at ease or provide you with irrefutable evidence to confront the problem.

Find an Address

Do you need to find a person’s address – someone who owes you money, an old friend, relative or missing persons? Our people tracing service will provide you with their current address within 24 hours. We can start the person trace with just a full name but sometimes may require additional information.
