Very friendly and fast order processing by Ms. Bauer and Mr. Wehn. The electrical system in my old building was a complete mess, but the experienced electrician from Hess fixed it within a few hours. The price/performance ratio was right, and the customer is our top priority. I'd be happy to do it again.

We rented a temporary power supply box from the company Hess – everything went perfectly, from communication and quote preparation to service including setup and dismantling. Very friendly, reliable and stress-free.

We had our photovoltaic system and storage unit installed by Elektro Hess and are completely satisfied! We save real money every day! From planning to installation, everything was top-notch! Elektro Hess also provided the temporary power supply box, and we were very well taken care of there too.
