It is often the ‘not knowing’ that is the worst aspect of cheating in a relationship.

At UK Private Investigators, our cheating partner and infidelity investigations can remove the doubts and either set your mind at ease or provide you with irrefutable evidence to confront the problem.

We’re here for you


It can be a difficult time should you suspect your partner is not being faithful. Obviously, if your partner is cheating, you definitely have the right to know. If they are not, then you need proof in order to alleviate your uncertainty and concern. It is only by having the facts that you can confront your partner or get on with your life.


Our discretion is paramount in cheating partner and infidelity investigations and you can rest assured that your partner will not know of our existence and that you will receive all the evidence you need. Our final reports will be accompanied by photographic or video evidence. This will prove that either your fears are justified and that your partner has been unfaithful, or possibly that you have no need to worry as your partner is innocent and you can continue your relationship as normal with peace of mind.



Out of the 939 cheating partner and infidelity investigation cases we have worked in the past 18 months, over 98% of the cases proved that the clients suspicions were correct and they received the evidence to prove it.
