🇬🇧 Front-of-Pack Nutrition Labeling in UK

Front-of-pack nutrition labeling provides at-a-glance nutrition information and is guided by the FSA Reference Intake and traffic light system in United Kingdom.

What the Rule Is

Front-of-pack nutrition labeling (FOPL) appears on the front or main display panel of food packaging, offering a quick visual summary of nutritional content. Unlike the mandatory back-of-pack nutrition table, FOPL requirements vary between markets and are evolving significantly. The UK uses the voluntary multiple traffic lights (MTL) scheme — red/amber/green per nutrient — in the government-recommended format adopted by most major retailers.

What You Must Include
  • Energy value per serving or per 100g on front of pack (EU/UK)
  • Key nutrients presented in the FOPL must match the back-of-pack Nutrition Facts
  • Reference intake (RI) percentages where required
  • Color coding or rating system aligned with local guidance
  • No claims that contradict the FOPL nutritional profile
Common Violations
  • FOPL data that contradicts the nutrition facts panel values
  • Using a voluntary FOPL scheme (e.g., Nutri-Score) incorrectly
  • Claim combinations that create a misleading overall impression (e.g., "high protein" prominently displayed while FOPL shows high saturates)
  • Not updating FOPL after recipe changes
  • FOPL values based on uncooked vs. cooked product confusion
Examples: Compliant vs Non-Compliant

Compliant Examples

UK traffic light labels showing red/amber/green for fat, saturates, sugars, salt with RI% per portion
Nutri-Score A–E grade aligned with the product's nutritional profile
Front-of-pack energy per serving in kcal/kJ matching the nutrition table

Non-Compliant Examples

Energy value on front of pack that differs from the nutrition panel
Using Nutri-Score "A" on a product with high saturates
Missing reference intake percentage when using the UK traffic light system
