Our history

Founded in 1937 with our first performance contract, our company has grown steadily: the post-war boom in collective heating, the challenges of the energy crisis, internationalization, diversification... we have always been there to support our customers. Compagnie générale de chauffe (CGC), formerly Chauffage Service, became Dalkia in 1998 and has been a wholly-owned subsidiary of EDF since 2014.

The beginnings

One evening in the winter of 1937, the boilers at the Villiers-Saint-Denis hospital (Aisne) stopped working. Léon Dewailly, founder of the company Chauffage Service, intervened immediately. The repairs were so quick and efficient that the hospital director asked for a contract to operate and maintain the system, with a guaranteed temperature.

The first energy performance contract was born!

Today, the hospital is still a Dalkia customer.
