All of Weetabix's produce is sourced from within the UK. They mention that they have 160 farmers in the UK that form their Grower Group.

"We use agency labour in our UK manufacturing areas, which is sourced through a reputable recruitment agency. We also have third party suppliers on site which provide contractors. We outsource certain services where specific expertise may be required and a number of non-key activities, such as engineer support, site maintenance and logistics are also outsourced.

All of the wheat for our big Weetabix biscuits is harvested less than 50 miles from our Burton Latimer mill by our Grower Group, which is formed of around 160 farmers dedicated to best practice and responsible production."
