An extraordinary tale of vision, commitment and sheer hard work, the OCS story starts way back in 1900 with the formation of The New Century Window and General Cleaning Company, a small independent window cleaning enterprise. Since then, we have grown from one man with a ladder, pail and pushcart to an international business providing a range of essential services in facilities owned by our clients, with more than 86,000 colleagues worldwide.

 A history of OCS on film

From the smallest of beginnings, OCS is now an extended family that reaches around the world. A lot has changed since 1900, but our purpose remains the same: to care for our colleagues, our local communities and the environment, and to deliver outstanding service for our customers. This is the OCS way.
