Hamilton took over from former chief executive Lin O’Brien this April following her retirement from HCL.
Hamilton, who has worked for the company for over three years, says he is looking forward to building upon the success of HCL and O’Brien’s work.
He said: “My goal is to work in partnership with schools to increase school meal uptake as well as continuing to deliver healthy and nutritious meals.
“With parents and schools facing tightening budgets, one of our biggest challenges in this competitive market will be delivering affordable school meals without compromising on quality.
“We want to continue to invest in our customers, ensure our school meals keep up with the latest nutritional guidelines and food trends and maintain good working relationships with our clients, suppliers and of course our harshest critics – the students.”
Hamilton will hold the new position until December 2018, and a decision by the HCL board will be made in September 2018 to appointment a permanent chief executive.
HCL provides school lunches across Hertfordshire to the majority of primary schools and half of all secondary schools in Hertfordshire.
