Unchecked electrical systems may have defects that can cause accidents or fires. The E-Check helps identify risks early and ensures compliance with legal regulations.

Only certified electrical specialist companies that operate according to DKE standards are permitted to perform the E-Check. Trained electricians with special certification carry out the inspection.

The inspection covers wiring, protective measures such as RCDs (Residual Current Devices), electrical appliances, earthing, as well as surge protection against lightning strikes or power surges.

For private households, an E-Check is recommended every 2 to 4 years, whereas in commercial and industrial settings, it is required more frequently depending on regulations. After remodeling or renovations, an inspection should always be carried out to ensure safety.

It increases safety, protects against accidents, provides insurance proof, preserves the value of installations, and ensures compliance with legal regulations.

The cost is usually between 100 and 300 euros, depending on the size of the installation and the amount of testing required. Extensive inspections may be more expensive.

If safety deficiencies are identified, they must be corrected by a certified professional company. In severe cases, usage restrictions or even shutdown may be necessary.

The E-Check certificate confirms that the inspected systems are safe and compliant with standards. It includes documentation of the inspection and recommendations for possible repairs.
