Demonstrating our compliance and competency
At Tremark Associates, we understand the critical importance of maintaining both positive public relations and legal compliance in our industry.
You were extremely clear on what info you required to effect service, and you were very efficient in checking the requirements of certifying service, to ensure that you did so in compliance with Scots law, as the matter related to service of Scottish proceedings. Julia was very friendly and efficient.

Aware of the potential impact of our actions on our clients’ reputations and our own standing, we approach investigative activities with utmost sensitivity and diligence.
Any professional investigator in the private sector, must ensure that they are compliant with all UK legislation in undertaking their investigations. Click here for our directory of legislation that must be considered.
Recognising the absence of statutory regulations, we took the initiative in early 2013 to establish rigorous self-regulatory standards to demonstrate to our clients that we are committed to legal compliance and competence.
Here are the milestones and achievements that underscore our dedication to compliance and competence:
