We still make MARS bars at the same factory where they were originally produced in 1932. Almost 90 years later, in Slough, England, we can make nearly three million bars a day filled with caramel and nougat, covered in rich milk chocolate - remaining loved and enjoyed by many across the UK.

Despite sweets rationing and a gold ink shortage during World War II, MARS bars were successfully distributed to troops in the UK and prisoners of war in Germany from 1939 to 1945.

A new way to enjoy MARS comes to our stores in 1989, and it’s cold. Ice cold. Welcome MARS Ice Cream!

We’re committed to growing with sustainability in mind. This is why, for the past decade, we’ve collaborated with a number of partners to tackle the environmental and social challenges facing the cocoa sector. To learn more, we invite you to read about how we're reshaping the future of cocoa, in our work Cocoa for Generations.
