Client testimonials

I don’t usually post reviews but I just wanted to say a massive thanks again for the work which was completed on my behalf. I was faced with divorce proceedings from my adulterous ex-wife, PrivateInvestigators-UK were able to gather the evidence that I needed in order to prove that she had a new partner. Without the images that were taken I would have been in a much weaker position. I can say that the money I have spent I have made back more than 1,000 fold. The evidence was collected quickly and I was given regular updates. The tactics and techniques used were ingenious and she had no idea that she was being watched until it was too late. I would recommend this service to anyone, thank you again.

— Michael D, Nottinghamshire

I can’t thank PrivateInvestigators- UK enough for the work they did tracing my biological mother. I had spent so much time trying to find her myself that I thought it was probably going to be impossible. After I decided to get professional help and open a case, I was stunned to receive all of the information that I asked for in less than one hour. What a great service. My only regret was not seeking professional help sooner.

— Mia, Southampton

Thank you for a superb service. The quality of evidence gathered far exceeded what I had hoped for, and it took less time than we had budgeted for which was another added bonus. The investigator used a “discreet” camera to capture video evidence at short range, watching the video back felt like we were in the room. The footage is very clear footage. I would not hesitate to use this firm again for any type of investigation.
