Preparation of expert reports
With our expert certified by BDSH e.V., we prepare detailed and reliable private and insurance reports for electrical low-voltage systems. We provide precise support in identifying the causes of damage and assessing the condition of the installation, giving you solid, well-founded facts in the event of disputes.

Well-founded expert reports: Precise analyses & clear facts
In the event of damage, complex technical malfunctions or legal disputes, a precise and independent expert report is essential. Whether it is clarifying the causes of fire in electrical distribution systems, assessing surge damage or verifying proper installation in accordance with standards – mere assumptions are not enough when dealing with insurance companies. Insufficient documentation of the system condition can quickly lead to significant financial losses in the event of a dispute. With personal expertise and neutrality, we provide you with sound facts. We expose weaknesses without compromise, determine the causes of damage beyond doubt and give you a reliable tool to clearly substantiate the facts.
