The deal, worth more than £20m, will see Leith’s, a Compass sport, leisure and hospitality brand, work in partnership with the centre to introduce a new range of food concepts and creative menus.
The contract was awarded following a competitive tendering process involving a number of the major and bespoke catering companies.
Mark Taylor, chief executive, QEIICC said: "This contract heralds a new era for catering at the QEIICC. We were looking for a caterer that we could work in close partnership with; a company that would work with us and our clients in a proactive collaborative and bespoke fashion.
"Although the Centre has worked with Compass for many years, a European wide tendering process was conducted and the contract was highly contested with a number of exceedingly strong tender returns. Leith’s/Compass have been selected again to work with the Centre based upon a combination of their partnership approach, depth of delivery and flexibility, combined with exceptional service and innovation."
Colin Bailey, managing director for Compass sport, leisure and hospitality said: "Our partnership with the Queen Elizabeth II Conference Centre spans over two decades and I’m thrilled that we have been given the opportunity to build on this longstanding relationship and excited about the plans we have in place.
"The conference and events market is extremely competitive; vital to the success of a venue is its ability to offer something different and I believe our new food concepts and chef partnerships coupled with the fantastic conference facilities at the QEIICC have enabled us to do this."
Compass will be working with Masterchef 2009 winner Steve Groves, now head chef at Roux at Parliament Square.
