The three-year contract is worth approximately £3.5 million a year to the company, which delivers a wide range of frozen, chilled and ambient goods to caterers.
“We are very pleased to have won the contract to supply to McMullen,” said Holdsworth chairman Michael Holdsworth. “Over the past 42 years we have grown to become a respected food service distributor in the UK as a result of our commitment to offering customers a competitive package with the best quality, value for money products and excellent service.
“We are delighted to forge a partnership with McMullen, which is a company that shares our values.”
The independent Hertfordshire-based brewer and pub operator operates in the south of England, from central London to Chelmsford in the east, to Fleet in the west and to Milton Keynes in the north.
Paul Robbins, food development manager at McMullen, said: “Holdsworth supports our vision whole-heartedly. The team is committed and experienced, and we are very pleased to be working with them over the next three years.”
Holdsworth has grown both organically and through acquisition to reach an annual turnover of approximately £49m for the last financial year - a 7.4 per cent increase on the previous year.
Last year the firm acquired four new businesses in Derbyshire, Yorkshire and Staffordshire.
