30 years of experience!
Monnay Electricité SA was founded by Alain Monnay in 1988 in St-Maurice and was taken over on April 1, 2015 by Gaïl Rappaz and Tobias Gaillard.
Our wide-ranging sector of activity extends from homes to industry and crafts.
We operate mainly in the Bas-Valais and Chablais regions, but also in the central Valais and on the Riviera.
