Independents by Sodexo has been awarded a five-year contract to manage catering and cleaning services at The King's School, Worcester.
The King's School was founded in 1541 and currently has more than 1,400 pupils aged from two to 18.
The £4.25 million contract will see the caterer introduce "a wide range of dishes with a focus on fresh, nutritious and seasonal food"' from 1st September.
A 29-strong cleaning services team will use cleaning solutions around the schedule of The King's School.
Jeremy Alderton, managing director of Independents by Sodexo, said: "We know that young people want variety in their food but are also conscious about sustainability and provenance. Our highly skilled chefs will be creating a selection of dishes using sustainably sourced ingredients that will not only interest and excite the pupils, but will also power performance to help them get the most out of school."
