The family-run business, now in its 21st year, has contracts in education, business and industry sites across the north of England, and in April this year was the winner of the CSC Contract Catering Award.
As part of its growth strategy, the company increased its sites by 37% over the last two years and has plans to double in size within the next five.
Tony Trainor, Mellors chief operating officer said: “This is a great September start for us to have smashed through the landmark 200 number of sites which is a combination of great retention rates and winning several new site contracts.
“We have had an amazing 18 months - winning the prestigious national contract caterer of the year award 2017, recently getting through to the BIBA’s awards finals in three categories and now having over 200 sites to our name.
“It comes down to passion, hard work, great staff and planning and it just re-iterates to us and our customers that we are the first choice contract caterer in the north.”
