Food labels provide you with information to help you choose food. Manufacturers must follow clear legal guidelines about what labels can and cannot show. 

You can also find out more about food labelling on the Food Standards Agency website. 


Large food businesses (250 or more employees) must display calorie labelling at the point of choice for the customer. This can be on physical menus, online menus, food delivery platforms and food labels. 

This includes non-prepacked food served in restaurants, cafes and supermarkets so consumers can make healthier choices. 

Prepacked food and drink are already required to display nutritional information. 

Smaller food businesses are not legally required to use calorie labelling but it is encouraged by the government.
