Bouygues E&S x Equans = Equans Switzerland

Have you heard?

Bouygues Energies & Services and Equans have come together to create something new. In the course of 2024, both companies will be united under one umbrella brand: Equans Switzerland. The best part? Multiplying two top brands creates one thing above all: more benefits for you.

Stronger together

Going forward, we will broaden our service portfolio even further and support you as a full-service provider throughout the entire lifecycle of buildings, districts and infrastructures.

Thanks to the experience and global expertise of our almost 90,000 highly qualified employees worldwide, we are able to offer our customers integral, flexible and intelligent solutions in every area of building technology, facility management, energy supply technology, energy/transport/telecom, process automation, smart buildings/cities energy optimisation as well as digitalisation.

At the core of this is our ambition to make our customers' lives more comfortable, while simultaneously making a significant contribution to emission control and promoting renewable energies. 

Next steps

Until everything is merged under one umbrella brand, you will continue to interact with both brands – for now you can choose between both websites.

Do you have any questions or suggestions regarding the ongoing rebranding? Ivan Widmer and his team will be happy to help you.

What happens when two successful brands merge?

The merger of Bouygues Energies & Services and Equans also brings together the strengths of two major Swiss companies. In the end, the result will be one thing above all: more for you.

Continuing our story

There is an eventful history to our company. Our roots lie in Switzerland with the founding of Atel and Kummler+Matter at the beginning of last century. At about the same time Francis Bouygues founded the Bouygues Group in 1952. The paths of the two companies met in 2018 and the merger resulted in Bouygues Energies & Services Switzerland.

The fact that we are a family business has shaped us. We are aware of our responsibility towards our employees, society and the environment. The next milestone in our company's success story has now been completed: october 2022 – Takeover of Equans by Bouygues. We are excited to continue our journey together under the Equans Switzerland brand.
