Labelling food for the consumer

Learn about UK food labelling laws for prepacked, loose, and online seafood – including rules on allergens, ingredients, origin, and product claims.



Consumers rely on clear and accurate food labelling to make informed and safe choices. 

Information appears on packaging or, for loose food, on nearby labels. Additional details may be provided through sales materials, brochures, websites or invoices.  

Labelling requirements for prepacked food 

Under the FIC, all prepacked food intended for the consumer must be labelled with:

  • The name of the food: For seafood, fish labelling rules dictate which commercial names must be used for each species. Link to fish labelling page
  • ‘Best before’ or ‘use by’ date. Find out guidance on choosing the correct date type. 
  • Any necessary warnings: e.g., ‘may contain small bones’ or allergens warnings.
  • Net quantity information: This is the weight of the product that is intended to be consumed. For example, ice glaze or vinegar should not be included in the net weight. However, edible ingredients like olive oil should be included. In this case a QUID declaration stating amounts of fish and oil would be needed. We have produced guidance on how ice glazing should be declared.
  • List of ingredients (if more than one): Allergens must be highlighted in bold. For example, cod (fish), wheat flour (gluten).
  • QUID declarationA declaration of the quantity of characterising ingredients (QUID) may be necessary if one or more characterising ingredients are present. These are ingredients that could affect a consumer's purchase decision. For example, the quantity of fish in a fish pie, or an ingredient emphasised in the name or packaging images.
  • Country or place of origin: Unprocessed seafood will use the country of farming or catch area as its origin. Once processed the origin will become the place of the last processing. However, care must be taken not to mislead consumers. For example, do not call Norwegian salmon, smoked in Scotland, 'Scottish smoked salmon' without stating it came from Norway.
  • Lot number: Helps trace the product in case of a food safety issue. A production date or use-by date can be used if it identifies all products in a batch.
  • Special storage conditions: For example, the temperature required for the product to remain safe until the use-by date stated.
  • Instructions for use or cooking, if necessary
  • Name and UK address of the responsible business: This must be a UK address, which could be be the producer, the brand owner, or the importer. 

Labelling requirements for loose (non-prepacked) food 

For food sold loose, the FIC requires: 

Labelling for online food sales

Food sold online must comply with the same labelling laws as food sold in physical stores.  

If sellers don’t have the full information at the time of sale, they must provide it after the sale but before delivery, including the durability date.
