The Fine Food Company and Creativevents have won a five year £4m extension to their deal to deliver food and drink concepts at RHS Hampton Court Flower Show.
The new deal will begin in July 2014. Fine Food Company and Creativevents were originally awarded a three year contract in 2011.
The two caterers also work in partnership at the Royal Horticultural Society's Chelsea Flower Show.
At Hampton Court they plan to introduce a new street food themed zone along with outlets such as a champagne and seafood bar, wine and Pimms bars and coffee bars.
Creativevents managing director Adrian Willson said: "Our close working relationship with the Fine Food Company has enabled us to deliver a truly bespoke food experience which delivers real value for money to a very discernible customer."
Fine Food Company managing director Rob Tame added: "Our expertise at cooking to order while coping with high volumes but with premium concepts comes from our wide ranging experience with a variety of audiences and attractions. We work very hard to deliver a unique event experience for our client and customers and both companies are committed to animal welfare, sustainability and sourcing good local ingredients."
