Dolos Investigations

Dolos Private Investigators care about finding you the truth and getting you the answers. Sometimes the result is painful and sometimes the result is innocent, but we will get you the result.

We are run by an Ex-Detective Sergeant who was responsible for covert operations, but also managed high risk offenders and vulnerable victims. We know that your privacy is paramount and that you the customer are our focus.

Nathan is an exellent surveillance operative. His reporting is professional and concise, he is diligent and goes the extra mile. I would be happy to recommend him to anyone who requires his services.

Fully recommend Nathan’s services. Straight talking and approachable. Did exactly what we asked for and he took the time to call and explain his report step by step. Also was kind enough to offer advice, over and above what we’d asked for, based on his knowledge and experience. Kept us updated step by step of the way and kept to the timelines promised. A no nonsense service. Thank you Nathan, your work was invaluable.

A to Z

We used Dolos investigations to help with a problem we had. I can honestly say Dolos were totally professional in what they did. We would not hesitate in recommending them to anyone who seeks the truth and justice. We spent a fortune on solicitors but the best decision we made was using Dolos which was a lot more cost effective. Thanks Nathan.
