Rob Hutchison, chief operating officer at Müller Milk & Ingredients, said: “The whole dairy supply chain is facing into increased inflationary pressure, and we know that our supplying farmers are seeing rising production costs.

“With markets strengthening, we wanted to make farmers aware of this decision as early as possible, giving them the information to support forward planning over the winter period.

“We will of course continue to monitor supply and demand in the coming months.”
